An object of the present invention is to provide a coating composition and a polycarbonate resin molded article having good appearance, transparency and adhesion, and capable of imparting an unprecedentedly high level of wear resistance to the surface of a substrate. An organosiloxane resin composition comprising (A) colloidal silica (a component), (B) a hydrolyzed condensate of an alkoxysilane (b component), (C) a curing catalyst, and (D) a solvent, In the organosiloxane resin composition, the chemical shift of the silylmethyl group proton of the organosiloxane resin composition has a specific integrated value in a specific range of positions, and the solubility parameter of the solvent is 10.0 to 13.2. An organosiloxane resin composition and a surface-protected polycarbonate resin molded product. [Selection diagram] None |
