Beschreibung
Zusammenfassung:	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 RCSiX4-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 optionally (c) an acrylate modified polymer; and (ii) a thermoset (silica filled) organopolysiloxane, top coat on said UV cured primer layer.
