Optical body

A transparent laminate including a transparent substrate and structure layer, wherein the structure layer contains protrusion portions, depression portions, or both on a surface thereof, and an average distance between the adjacent protrusion portions or between the adjacent depression portions is equal to or less than a visible light wavelength, the structure layer includes a polymerized product of an active energy ray curable resin composition, the resin composition includes a composition of a (meth)acryloyl group-containing polymerizable compound, the compound composition includes one or more from each of (A), (B), and (C):

Transparent laminate

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&#xb0; or more and 74&#xb0; or less; and storage elastic modulus at 180&#xb0; C. of the structure layer being less than 0.5 GPa.

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.

Transparent film for face protection shield

The purpose of the present invention is to prevent an increase in reflectance and a decrease in transmittance, retain the intact instantaneousness and ease of stripping, improve the releasability of the adhesive, avoid the generation of distortion due to the thickness of the adhesive, and ensure the visibility, by laminating filmy members () each equipped with a moth-eye structure (). This transparent laminate () comprises a plurality of filmy members () which each comprise a base () and, disposed on at least one surface thereof, a structure () made up of recesses and protrusions which have been regularly arranged at a pitch not longer than the wavelengths of visible light. At least the ends of the filmy members () have been superposed, with a pressure-sensitive adhesive layer () interposed therebetween. In the superposed filmy members (), there is a space () between the opposed structures ().
