摘要： A transparent laminate including: transparent substrate; and structure layer which contains protrusion portions, depression portions, or both on a surface thereof, average distance between the protrusion portions adjacent or the depression portions adjacent being equal to or less than wavelength of visible light; the structure layer including polymerized product of active-energy-ray-curable resin composition including composition of (meth)acrylate-based-polymerizable compound; the composition including at least any of the following (A) and (B), and the following (C) and (D): (A) ester (meth)acrylate of trihydric alcohol having main and side chain each including alkyl chain; (B) ester di(meth)acrylate of ethylene-oxide-modified bisphenol A; (C) polyalkylene glycol di(meth)acrylate; and (D) ester di(meth)acrylate of dihydric alcohol having main chain including linear alkyl chain; water contact angle on the surface of the structure layer being 26° or more and 74° or less; and storage elastic modulus at 180° C. of the structure layer being less than 0.5 GPa.

摘要： There is provided a transparent film for a face protection shield in which transparency is enhanced and visibility from a non-wearer is also enhanced, the transparent film for a face protection shield including: a transparent base material having flexibility; and a transparent resin layer configured to be laminated on at least one of surfaces of the transparent base material, the transparent resin layer having on a surface a plurality of structural bodies including concavities or convexities provided at a pitch of less than or equal to a visible light wavelength. A refractive index of the transparent base material is different from a refractive index of the transparent resin layer, and an interface between the transparent base material and the transparent resin layer has a concave-convex shape.
