PROBLEM TO BE SOLVED: To provide a resin composition for FRP for obtaining a fiber-reinforced plastic molding in which an added ultraviolet absorber does not bleedout nor sublimate, is not eluted in a solvent such as hot water or an alcohol, nor loses its potency on contact with an acid or alkali, and which is hard to discolor even if it is exposed to irradiation of light such as daylight for a long period of time. SOLUTION: The resin composition contains a reactive ultraviolet absorber in which a methacryloyl group is introduced into a benzotriazole skeleton, as an ultraviolet absorber. The fiber-reinforced plastic molding obtained by using the resin composition forms a polymer skeleton by the reaction of the reactive ultraviolet absorber with a resin component in the process of molding and curing. Thus, the ultraviolet absorber becomes hard to be separated from the fiber-reinforced plastic molding, and becomes hard to bleedout or sublimate. COPYRIGHT: (C)2005,JPO&NCIPI
