(57) [Abstract] [Purpose] To provide a durable plastic molded article having high abrasion resistance, scratch hardness and solvent resistance. [Structure] An organopolysiloxane resin composed of an alkoxysilane, a (partial) hydrolyzate thereof, a partial condensate thereof, or a mixture thereof and a methacrylate acrylic resin having a hydroxyl group are thermally cured by reaction on the surface of a plastic substrate. A first layer, a second layer obtained by reacting the organopolysiloxane resin and a methacrylate-based acrylic resin having an alkoxysilyl group by thermosetting, and a third layer obtained by thermosetting the organopolysiloxane resin. A plastic molded article having a protected surface, which is formed by sequentially laminating from a first layer. |
