ABSTRACT:
A photocurable ethylenically unsaturated liquid coating composition consisting essentially of: 1- polyethylenically unsaturated material in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups; 2- a polyamine resin; and 3- an hydroxyalkyl phenone photoinitiator to speed the cure. The photocure rate is also speeded by combining a tertiary amine-functional acrylic copolymer, an allyl-functional resin, and a maleate-functional resin in a weight ratio of about 15-65/5-45/30-70. In preferred practice both expedients are used to maximize the cure speed.
