ABSTRACT:
A coated polycarbonate article comprising a polycarbonate substrate having (i) a primer layer containing a UV cured reaction product of (a) a polyfunctional acrylic ester monomer, (b) an organic silicon compound represented by the formula R.sup.4.sub.c SiX.sub.4-c wherein R is an organic group containing olefinic unsaturation, X is an alkoxy, acyloxy, and aryloxy group, and c is an integer of from 1 to 3, and (c) an acrylate modified polymer; and (ii) a thermoset silica filled organopolysiloxane top coat on said UV cured primer layer.
A process for producing a coated polycarbonate article comprising (i) priming a polycarbonate substrate with a UV curable primer composition containing (a) a polyfunctional acrylic acid ester monomer, (b) an organic silicon compound represented by the formula R.sup.4.sub.c SiX.sub.4-c wherein R, X and c are as defined above, (c) an acrylate modified polymer, (d) a UV photoinitiator, and (e) resorcinol monobenzoate; (ii) UV curing said primer composition; (iii) applying a colloidal silica containing organopolysiloxane top coat composition to the primed substrate; and (iv) curing the organopolysiloxane.
