To provide a resin substrate provided with a coating layer having excellent weather resistance and thereby capable of maintaining properties of the resin such as transparency and fracture resistance over a long period of time. n A resin substrate provided with a coating layer, which comprises a substrate made of a resin containing an aromatic ring and a coating layer containing an acrylic polymer having 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 an ultraviolet light absorbing component selected from a polymer having ultraviolet light absorbing groups and an ultraviolet light absorber, having an average of absorption coefficients of from 3.5 g/(mg·cm) to 100 g/(mg·cm) to light in a wavelength region of from 350 nm to 380 nm, formed on at least one surface of the substrate. |
