Abstract
A UV-curable coating composition including an acrylate oligomer and a vinyl acrylate compound, the latter of which can act as both a reactive diluent and an adhesion promoter. The vinyl acrylate compounds have good miscibility and low viscosity, and impart to the cured primary coating a high adhesion to glass. With the use of a free radical photoinitiator, the vinyl acrylate compound increases the speed of cure of the uncured primary coating.
