Master manufacturing method, optical body, optical member, and display device
There is provided a master, an optical body, and a master manufacturing method, including: forming, on a surface of a master body that includes a base material, a periodic micro concave-convex structure in which an average cycle of concavities and convexities is less than or equal to visible light wavelengths; forming an inorganic resist layer on the surface of the master body; microparticulating and spraying an organic resist dissolved in a diluent onto the inorganic resist layer, to thereby form an organic resist layer, on a surface of which is provided a macro concave-convex structure in which the average cycle of concavities and convexities is greater than the visible light wavelengths; and etching the organic resist layer, the inorganic resist layer, and the master body, to thereby superimpose and uniformly form the micro concave-convex structure and the macro concave-convex structure on the surface of the base material.
Surfacing materials and method of manufacture
A surfacing material includes a substrate having a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an electron beam radiation curable material applied to the bottom side of the substrate. The coating is an epoxy acrylic or urethane acrylic laid upon the substrate. The epoxy acrylic or urethane acrylic is irradiated with UV-radiation to produce a UV-radiation layer wherein the epoxy acrylic or urethane acrylic is neither hardened nor is an entire layer of the epoxy acrylic or urethane acrylic crosslinked but rather the epoxy acrylic or urethane acrylic only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.
BIAXIALLY STRETCHED POLYESTER FILM AND METHOD FOR PRODUCING THE SAME
A biaxially stretched polyester film and a method for producing the same are provided. The biaxially stretched polyester film includes a polyester resin base layer and a matte layer. The polyester resin base layer includes: (1) 50 to 95 wt % of a polyester resin base material, and an intrinsic viscosity of the polyester resin base material being between 0.5 and 0.8 dL/g; and (2) 0.01 to 5 wt % of a high viscosity polyester resin material, and an intrinsic viscosity of the high viscosity polyester resin material being between 0.9 and 1.1 dL/g. The matte layer includes: (1) 50 to 95 wt % of a polyester resin matrix material, and an intrinsic viscosity of the polyester resin matrix material being between 0.5 and 0.8 dL/g; and (2) 0.3 to 40 wt % of a plurality of filler particles, and the filler particles having an average particle size of between 0.15 m and 10 m.
Thermoplastic resin film, its manufacturing method, and laminated body
Provided is a thermoplastic resin film having at least one of film surfaces being excellent in printability, having sufficiently low internal haze, and exhibiting a favorable matte appearance. A thermoplastic resin film according to the present invention composed of a thermoplastic resin composition (C) including at least one kind of a thermoplastic resin (R) and fine particles (P) having a volume average particle diameter of 0.5 to 15 m and a refractive index different from that of the thermoplastic resin (R) by 0.02 or more. At least one of film surfaces satisfies formulas (1) and (2).
G.sub.L60(1),
G.sub.L35G.sub.HG.sub.L10(2)
(In the formulas (1) and (2), G.sub.L is 60 gloss (%) at 20 C., G.sub.H is 60 gloss (%) when the thermoplastic resin film is heated at a temperature 10 C. higher than a glass transition temperature of the thermoplastic resin composition (C) for 30 minutes, then cooled to 20 C.).
Textured hardcoat films
Textured hardcoat films are disclosed for preferable use in film insert moulding. Texture in the hardcoat film is created through the use of a textured protective overlayer, which can impart texture to the curable coating of the hardcoat film. This process preferably avoids the need to alter the composition of the curable coating to allow for texture and preferably produces a hardcoat film with a matte and reduced-glare finish. An apparatus and a method embodying the invention are disclosed.
Matte film and method of manufacture therefore
A film structure having a matte film surface and method of manufacture thereof. The preferred embodiment of the present invention contemplates a blend of polyethylene homopolymer or copolymer resins, coupled with one or more platelet shaped (non-spherical) inorganic or organic fillers. The matte polyethylene film surface as prepared from these polymer/filler blends exhibits a low gloss matte surface for wide utility in laminated and non-laminated, food and non-food, packaging and non-packaging applications. A unique and heretofore uncontemplated technique of manufacture exploiting the phenomenon of die swell as enumerated herein is utilized during production to facilitate the reorientation of the fillers during the extrusion process to produce the matte surface effect.
Plastic Molded Product
A plastic molded product includes a plastic body provided with a plurality of holes, which are recessed in a common depth direction, on a surface of the plastic body. The holes include: an inner surface including an inlet a specific reference plane perpendicular to the depth direction and including at least a portion of the inlet and a depth reference point, which is spaced away from a center point on an inlet side of the specific reference plane toward a bottom side of the hole, the depth reference point being spaced away by a distance equal to of a maximum value of an inlet side bore diameter on the specific reference plane. A deepmost portion of the inner surface of the hole is in a position which coincides with the reference point or is deeper than the reference point toward the bottom side.
Printer-compatible, pre-embossed films
Decorative films, useful for making a wide range of decorative laminates, that have a relatively deep texture on one major face and a relatively smoother, print receptive surface on the other major face. Notwithstanding the deep texture, the films have superb tracking characteristics and are compatible with a wide variety of automated printing operations. This allows automated printing equipment to print information directly onto the films.
METHODS FOR PRODUCING HIGHLY THERMOFORMABLE ACRYLIC SOLID SURFACE
Articles may be formed from a thermoformable composition, the thermoformable composition including: a) about 35 wt % to about 95 wt % of an acrylic pre-polymerized syrup; b) about 0 wt % to about 10 wt % of a comonomer; and c) about 5 wt % to about 65 wt % of a filler having an average particle size (d50) in a range of about 0.1 m to about 50 m; wherein the article has a surface having a gloss measurement at a 60 measurement angle within a range of about 0 Gloss Units to about 20 Gloss Units, and a roughness Ra within a range of about 1 microinch to about 100 microinches. Methods may include producing a thermoformed article by the steps of: i) preparing a thermoformable composition; ii) casting the thermoformable composition into a sheet; and iii) thermoforming the cast sheet against a mold to produce a thermoformed article.
