A coated polycarbonate article, and a process for producing said article, having improved abrasion and chemical solvent resistance comprising a polycarbonate substrate having deposited thereon (i) a primer layer comprised of a thermoplastic acrylic polymer; and (ii) a top coat containing a thermoset organopolysiloxane disposed on said primer layer. The process for producing said coated polycarbonate article comprises (i) priming the surface of a polycarbonate substrate with a thermoplastic acrylic polymer by forming a thin film of said thermoplastic acrylic polymer on the surface of said substrate, (ii) applying a top coating composition containing a further curable organopolysiloxane onto the primed substrate, and (iii) curing the further curable organopolysiloxane to form a hard, abrasion and chemical solvent resistant top coat which is tenaciously adhered to the polycarbonate substrate. |
