(Composition 7 for a Hard Coat Layer)

[0397] Polyethylene glycol diacrylate (M240 manufactured by Toagosei Co., Ltd.) 100 parts by mass

[0398] Photo-polymerization initiator (IRGACURE 184) 4 parts by mass

[0399] Fluorine leveling agent (F568, manufactured by DIC CORPORATION) 0.2 part by mass (in terms of solid)

[0400] Solvent (MIBK) 150 parts by mass

[0401] In addition, a Martens hardness of the resulting first hard coat layer was 250 MPa.

Comparative Example 5

[0402] A layered body was produced in the same manner as in Example 1 except for curing an applied film by irradiating the applied film with ultraviolet rays so that a cumulative light quantity is 200 mJ/cm.sup.2 under the condition of oxygen concentration of 200 ppm or less using a UV irradiation apparatus (manufactured by Fusion UV Systems Japan; light source, H bulb), as a curing condition of the first hard coat layer.

[0403] The layered bodies obtained in Examples, Comparative Examples and Reference Examples were evaluated concerning the following items. Evaluation results are shown in Table 2.

(Folding-Durable Test)

[0404] Each of the layered bodies of Examples, Comparative Examples and Reference Examples was cut to a rectangle of 30 mm×100 mm to prepare a sample. The prepared sample was attached to an endurance testing machine (DLDMLH-FU for U-shape Sliding Plate Test, manufactured by YUASA SYSTEM CO., LTD.) with a side of 30 mm fixed to the machine so that a bending radius R of the sample is 1.5 mm (diameter 3.0 mm). A test in which the entire area of the sample is folded 180 degrees with a surface on a side where the hard coat layer has been formed facing inward is repeated 100,000 times (stroke, ±30 mm; testing speed, 60 rpm), and the folding-durable performance was rated according to the following criteria.

[0405] +: Cracks are not produced in a sample

[0406] −: Cracks are produced in a sample

(Pencil Hardness)

[0407] The pencil hardness of each of the layered bodies of Examples, Comparative Examples and Reference Examples was measured according to JIS K5600-5-4 (1999) (load of 1 kg).

(Steel Wool (SW) Resistance)

[0408] The outermost surface of the hard coat layer of each of the layered bodies of Examples, Comparative Examples and Reference Examples was scrubbed to and fro 3500 times at a rate of 50 mm/sec under a load of 1 kg/cm.sup.2 using #0000 steel wool (trade name: BON STAR, manufactured by Nippon Steel Wool Co., Ltd.), and thereafter the presence or absence of a scuff on a surface of a hard coat layer was visually observed to be rated according to the following criteria.

[0409] +: There is no scuff

[0410] −: There is a scuff

(Antifouling Property)

[0411] The outermost surface of the hard coat layer of each of the layered bodies of Examples, Comparative Examples and Reference Examples was marked with an permanent marker, and then wiping out of a mark with a cellulose non-woven cloth wiper was tried 20 times to be rated according to the following criteria.

[0412] +: Mark can be wiped out

[0413] −: Mark cannot be wiped out

[0414] As shown in Table 2, the layered bodies of Examples were excellent in the folding-durable performance, the abrasion-resistance and the antifouling property and had the excellent pencil hardness of 7H or higher.

[0415] On the other hand, the layered bodies of Comparative Examples 1 to 5 were inferior in the folding-durable performance. In addition, the layered body of Comparative Example 5 was inferior in the folding-durable performance since adhesiveness between the first hard coat layer and the second hard coat layer was poor. The layered bodies of Comparative Example 3 and Reference Examples 1 to 3 and 5 were inferior in the pencil hardness, and the layered bodies of Reference Examples 2 and 4 were inferior in the abrasion-resistance and the antifouling property.

[0416] In addition, the layered bodies of Comparative Examples 1 and 2 intensively generate curls, and produced cracks only by stretching the curl in order to perform a folding-durable test.

Examples 22 to 42, Comparative Examples 6 to 16, and Reference Examples 6 to 13

[0417] Layered bodies were produced in the same manner as in Example 1 except for changing so as to have the composition and thicknesses shown in Table 3.

[0418] In addition, in Examples 38 to 40, a backside hard coat layer was formed, in the same manner as in the first hard coat layer, on a surface opposite to the surface of the substrate film having the first hard coat layer and the second hard coat layer provided thereon.

[0419] Further, a composition I for a hard coat layer of the second hard coat layer of Comparative Example 14 is as follows.

(Composition I for a Hard Coat Layer)

[0420] A mixture of dipentaerythritol pentaacrylate and dipentaerythritol hexaacrylate (M403, manufactured by Toagosei Co., Ltd.) 90 parts by mass

[0422] Photo-polymerization initiator (IRGACURE 184) 4 parts by mass

[0423] Solvent (MIBK) 150 parts by mass

[0424] In addition, a Martens hardness of the resulting second hard coat layer was 650 MPa.

[0425] The layered bodies obtained in Examples and Comparative Examples were evaluated in the same manner as in Example 1 concerning the folding-durable test, the pencil hardness, the steel wool (SW) resistance and the antifouling property. Evaluation results are shown in Table 4.

[0426] As shown in Table 4, the layered bodies of Examples were excellent in the folding-durable performance, the abrasion-resistance and the antifouling property and had the excellent pencil hardness of 4H or higher.

[0427] On the other hand, the layered bodies of Comparative Examples 6 to 16 were inferior in the folding-durable performance, the layered bodies of Comparative Examples 13 and 16, and Reference Examples 9, 10, 12 and 13 were inferior in the pencil hardness, the layered bodies of Comparative Examples 8 to 13 and 16, and Reference Examples 6 to 8, 11 and 12 were inferior in the abrasion-resistance, and the layered body of Reference Example 11 was inferior in the antifouling property.

[0428] In addition, the layered body of Comparative Example 15 was inferior in handleability since the substrate film thereof was thick and much heavier than the layered bodies of other Examples and Comparative Examples.

[0429] Further, although the layered body of Comparative Example 16 was similar in the composition of the substrate film, the first hard coat layer, and the second hard coat layer to the layered body of Example 22, the layered body had poor adhesiveness between the first hard coat layer and the second hard coat layer, resulting in inferior pencil hardness, and easily produced peeling off at an interface between the first hard coat layer and the second hard coat layer, resulting in inferior folding-durable performance and abrasion-resistance, because of forming the second hard coat layer after completely curing the first hard coat layer.

[0430] Layered bodies were produced in the same manner as in Example 1 except for changing so as to have the composition and thicknesses shown in Table 5.

[0431] In addition, a composition a for a cured layer of a monofunctional monomer having a composition described later was applied onto one surface of the substrate film to form an applied film, and the formed applied film was heated at 70° C. for 1 minute to vaporize a solvent in the applied film. Using a UV irradiation apparatus (manufactured by Fusion UV Systems Japan; light source, H bulb), the applied film was irradiated with ultraviolet rays in the air so that a cumulative light quantity was 100 mJ/cm.sup.2 to half-cure the applied film, and thereby a cured layer of a monofunctional monomer with a thickness shown in Table 5 was formed.

[0447] The layered bodies obtained in Examples, Comparative Examples and Reference Examples were evaluated in the same manner as in Example 1 concerning the folding-durable test, the pencil hardness and the steel wool (SW) resistance, and moreover, the following anti-interference fringe test was performed. Evaluation results are shown in Table 6.

(Anti-Interference Fringe Test)

[0448] With respect to each of the layered bodies of Examples, Comparative Examples and Reference Examples, a black tape (manufactured by TERAOKA SEISAKUSHO CO., LTD.) was bonded to a surface opposite to the side of the substrate film having the cured resin layer provided thereon. Then, using a spectrophotometer (MPC3100, manufactured by SHIMADZU Corp.), a surface on the side of the substrate film having the cured resin layer provided thereon was irradiated with light having an incident angle of 5 degrees, and reflected light in a specular direction which was reflected on a film was received to measure reflectances in a wavelength range of 380 nm to 780 nm, and then measured data in the wavelength range of 400 nm to 700 nm was approximated by a second-order polynomial, and a standard deviation was calculated from a difference between the measured value and an approximate value by the second-order polynomial in an arbitrary range of 50 nm.

[0449] Thereafter, a standard deviation of a wavelength range of 50 nm which has the largest standard deviation in the wavelength range of 400 nm to 700 nm was determined.

[0450] Further, with respect to each of the layered bodies of Examples, Comparative Examples and Reference Examples, a black tape (manufactured by TERAOKA SEISAKUSHO CO., LTD.) was bonded to a surface opposite to the side of the substrate film having the cured resin layer provided thereon, and then the presence or absence of the interference fringe was visually checked under three-wavelength tube fluorescent lamp.

[0453] As shown in Table 6, the layered bodies of Examples 43 to 56 were excellent in the folding-durable performance, the pencil hardness and the abrasion-resistance.

[0454] Further, in the layered bodies of Examples, the interference fringe at a bending portion was not found even though layered bodies were folded, and a moving interference fringe resulting from folding was not observed.

[0455] On the other hand, the layered bodies of Reference Examples 14, 16 and 17 were inferior in the anti-interference fringe performance since the layered bodies did not have a cured layer of a monofunctional monomer. Further, in Reference Example 15, although the layered body had the monofunctional monomer layer, an interference fringe was observed since a thickness of the layer was large.

[0456] Further, the layered body of Comparative Example 17 was inferior in the folding-durable performance since adhesiveness between the first hard coat layer and the second hard coat layer was poor.

[0457] Further, in the layered bodies of Reference Example 18 in which the first hard coat layer was too thick, Reference Example 19 in which the second hard coat layer was not formed, and Reference Example 20 in which the second hard coat layer was too thick, although cracks were not produced by folding the layered body with a backside facing outward in the folding-durable test, cracks were produced by folding the layered body with the surface facing outward. Further, Reference Example 19 in which the second hard coat layer was not formed was also inferior in the abrasion-resistance.

[0458] Further, in the layered bodies of Reference Examples 18 to 20, since a cured layer of a monofunctional monomer was suitably formed, the interference fringe at a bending portion was not found even though layered bodies were folded, and a moving interference fringe resulting from folding was not observed.

[0459] Layered bodies were produced in the same manner as in Example 1 except for changing so as to have the composition and thicknesses shown in Table 7.

[0460] The layered bodies obtained in Examples, Comparative Examples and Reference Examples were evaluated in the same manner as in Example 1 concerning the folding-durable test, the pencil hardness and the steel wool resistance, and moreover, the following total light transmittance test was performed. Evaluation results are shown in Table 8.

(Total Light Transmittance)

[0461] The total light transmittance (%) was measured according to JIS K 7361 using a haze meter (manufactured by MURAKAMI COLOR RESEARCH LABORATORY; product number, HM-150)

[0462] As shown in Table 8, the layered bodies of Examples 57 to 73 were excellent in the folding-durable performance, the abrasion-resistance and the transparency and had the extremely excellent pencil hardness of 5H or higher.

[0463] Further, in the layered bodies of any Examples, their cross-sections were observed with a microscope, and consequently elution of the material components of the substrate film into the first hard coat layer was recognized.

[0464] On the other hand, the layered bodies of Reference Examples 21 to 24, which did not use a polyimide film or an aramid film as the substrate film, were inferior in pencil hardness, and cross-sections thereof was observed with a microscope, and consequently elution of a material component of the substrate film into the first hard coat layer was not found.

[0465] Further, the organic EL layered body of Comparative Example 18 was inferior in the folding-durable performance since adhesiveness between the first hard coat layer and the second hard coat layer was poor.

[0466] Further, in the layered bodies of Reference Example 25 in which the first hard coat layer was too thick, Reference Example 26 in which the second hard coat layer was not formed, Reference Example 27 in which the second hard coat layer was too thick and Reference Example 28 in which the substrate film was too thick, although cracks were not produced by folding the layered body with a backside facing outward in the folding-durable test, cracks were produced by folding the layered body with the surface facing outward.

[0467] Further, Reference Example 26 in which the second hard coat layer was not formed was also inferior in the abrasion-resistance.

[0468] Further, Reference Example 28 in which the first hard coat layer was not formed was inferior in the pencil hardness.

[0469] In addition, the case in which the layered bodies obtained in Examples, Comparative Examples and Reference Examples were laminated on a commercially available organic EL layer to form layered bodies for organic ELs in which a layered body is laminated on one surface of the organic EL layer, results were the same as the above-mentioned results.

[0470] The layered body of the present invention can be suitably used as a surface material of a folding type image display device.
