<p>A surface-protected transparent plastic composite which comprises: a transparent plastic base; a coating layer (I), as a first layer, which has been formed on a surface of the base and is made of a resin composition comprising a resin component at least 50 wt.% of which is accounted for by an acrylic resin comprising 50 mol% or more repeating units derived from an alkyl methacrylate; and a coating layer (II), as a second layer, which has been formed on the first layer by heat-curing a resin composition comprising an organosiloxane resin comprising the following ingredients (a), (b), and (c): (A) colloidal silica (ingredient (a)) (B) a product of the hydrolytic condensation of a trialkoxysilane (ingredient (b)), and (C) a product of the hydrolytic condensation of a tetraalkoxysilane (ingredient (c)), the amounts of ingredients (a), (b), and (c) being 5 to 45 wt.%, 50 to 80 wt.%, and 2 to 30 wt.%, respectively. Also disclosed is use of the composite as a window glass. The composite has been significantly improved in wearing resistance and coating film adhesion.</p> |
