Heaps 4,517,327 May 14, 1985
Corcoran 5,279,862 Jan. 18, 1994
Hellmann 5,412,000 May 2, 1995

Appellants’ claimed invention is directed to a method for painting
plastic substrates comprising applying a base coat layer directly to the plastic
substrate, curing the base coat layer, applying a clear coat layer to the base
coat layer, and curing the clear coat layer. The base coat layer comprises
one of the recited binders, a colour-and/or effect pigment, a solvent, and an
adhesion-promoting composition comprising an ethylene vinyl acetate
copolymer, a chlorinated rubber, and a chlorinated polyolefin. The base coat
layer is applied in two stages: first, the base coat comprising the adhesion-
promoting composition is applied, followed by “a layer of a colour-and/or
effect-imparting coating composition which does not contain the adhesion-
promoting composition.”
