ABSTRACT:
A process for providing a protective coating on a polycarbonate substrate comprising (i) applying onto said polycarbonate substrate a priming emulsion composition containing (a) a thermosettable acrylic polymer, (b) an ultraviolet light absorber selected from the benzylidene malonates and cyanoacrylates, (c) water, and (d) a hydroxy ether or a lower alkanol; (ii) curing the thermosettable acrylic polymer thereby forming a primer layer containing a thermoset acrylic and an ultraviolet light screener on said substrate; (iii) applying a top coat composition containing a further curable organopolysiloxane; and (iv) curing said further curable organopolysiloxane thereby obtaining a thermoset organopolysiloxane top coat.
