Structures for forming an optical feature and methods for forming the optical feature are disclosed. In some embodiments, the structure comprises a patterned layer comprising a pattern corresponding to the optical feature; a base layer; and an intermediate layer bonded to the patterned layer and the base layer.

A replica master mold 10 comprises: a base material layer 11; and a surface shape body 12 formed on the base material layer 11 and having a fine irregular pattern, wherein a softening temperature of the surface shape body 12 is higher than a softening temperature of the base material layer 11.

Provided is an extensible decorative film that includes a surface layer having excellent scratch resistance and matte properties before and after extension, and a surface coating composition that may form such a surface layer.

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.

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 is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

In the method for manufacturing a three-dimensional structure of the invention, an ink for forming an entity portion is applied to a region where the three-dimensional structure is configured, and an ink for forming a sacrificial layer is applied to a region on a surface side of an outermost layer which is adjacent to a region to become the outermost. As the ink for forming a sacrificial layer, a first ink for forming a sacrificial layer and a second ink for forming a sacrificial layer are used. At the time of curing the ink for forming an entity portion, the viscoelasticity of the first ink is smaller than that of the ink for forming an entity portion, and at the time of curing the ink for forming an entity portion, the viscoelasticity of the second ink is greater than that of the ink for forming an entity portion.

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.)

A composition for extruding or injection molding low-gloss articles exhibiting improved color retention and mechanical properties as compared with conventional pigmented or painted PVC or TPO resins includes polypropylene, a thermoplastic polyolefin elastomer in an amount sufficient to impart superior impact resistance and at least one particulate delustering agent in an amount sufficient to provide low-gloss without sacrificing impact strength.

A structural body which comprises a base and a microrelief structure layer having a microrelief structure. The microrelief structure layer is laminated on the base so as to form the surface layer of this structural body, and the microrelief structure layer has at least one physical property selected from the group consisting of (A) and (B) described below. (A) The elastic modulus at 25 C. is 50 MPa or more, and the elastic modulus at 80 C. is 30 MPa or less. (B) The tensile elongation at break at 80 C. is from 20% to 100% (inclusive).

This invention relates to a method of manufacturing an optical sheet, including: (S1) forming a single layer by feeding a curable resin composition, (S2) obtaining the single layer having a transferred nanopattern on a surface thereof by passing the single layer formed in (S1) through a release mold having a nanopattern having a pitch of 50 to 500 nm and an aspect ratio of 1.0 to 5.0, and (S3) curing the single layer having the transferred nanopattern obtained in (S2).
