Abstract
A surface-protected plastic composite material comprising a transparent plastic, a coating layer (I) as a first layer stacked on the transparent plastic and a thermally cured coating layer (II) as a second layer stacked on the first layer, the coating layer (I) being formed of a resin composition containing at least 50% by weight, based on the resin content thereof, of an acrylic resin which is an acrylic resin containing at least 50 mol % of recurring unit based on an alkyl methacrylate, the thermally cured coating layer (II) being made of an organosiloxane resin formed from the following components a, b and c, The present invention provides a transparent plastic composite material that is remarkably improved in abrasion resistance and anti-peeling properties.
