Abstract
This invention provides an acid-hardening resin composition which is activated by exposure to actinic light, wherein the composition is a condensation polymerizable blend of (1) an aminoplast, (2) an alkyd resin; and (3) a sulfolene catalyst. When the invention coating composition is subjected to ultraviolet light exposure and a subsequent bake cycle, a film is obtained which has good mechanical properties and excellent adherence to substrates. In a further embodiment, a superior substantially 100% solids coating system is provided which comprises (1) an aminoplast; (2) an alkyd resin; (3) a sulfolene catalyst; (4) a photoinitiator; and (5) a polymerizable olefinically unsaturated monomer or prepolymer.
