Patent ID: 8354163

Claim:
A resin substrate provided with a coating layer, which comprises: a substrate made of a resin containing an aromatic ring, and a coating layer formed on at least one surface of the substrate, said coating layer having a thickness of from 0.5 μm to 10 μm and comprising: (1) an acrylic polymer comprising at least one member selected from the group consisting of an alkyl acrylate and an alkyl methacrylate, as main monomer units, and (2) an ultraviolet light absorbing component, wherein the acrylic polymer (1) has an acid value of at most 1 mg KOH/g, a glass transition point of from 60° C. to 150° C., and a mass average molecular weight of from 90,000 to 1,000,000, and wherein the average of absorption coefficients of the ultraviolet light absorbing component (2) to light in a wavelength region of from 350 nm to 380 nm is from 3.5 g/(mg·cm) to 100 g/(mg·cm), and said ultraviolet light absorbing component (2) is 2-[4-(4,6-bis-{2-hydroxy-4-[1-(6-methyl-heptyloxycarbonyl)-ethoxy]-phenyl}-[1,3,5]triazin-2-yl)-3-hydroxy-phenoxy]-propionic acid 6-methyl-heptyl ester.
