A method of improving the bond between a vinyl resin material and a polyurethane or acrylated polyurethane resin material which comprises coating a fused vinyl resinous layer with an aqueous acetic acid solution, drying the aqueous coating, applying an uncured polyurethane or acrylated polyurethane layer to the coated surface of the vinyl resin material and exposing the vinyl resinous composition layer and the uncured polyurethane or acrylated polyurethane resin layer to curing conditions to develop a strong and permanent bond between the two layers.
