ABSTRACT:
A method and a composition for forming electron beam curing high build coating film which method comprises the steps of preparing a specified coating composition, applying it to the surface of a substrate to be coated, and curing the coating film with the irradiation of electron beams or ultraviolet rays. The coating composition of the invention comprises a polymerizable resin (I) as the main vehicle component which is cured by the irradiation of electron beams or ultraviolet rays and has at least two polymerizable unsaturated double bonds and at least one hydroxyl group in its molecule, and a polyisocyanate compound (II). Further, a resin (III) having active unsaturated groups can be added to the above coating composition so as to improve the pot life of the composition.
