Abstract
A process for the formation of an integrated, cured coating which comprises applying to a base material a coating composition containing ethylenically unsaturated groups and free isocyanate groups each in a specific amount to form an undercoat which is subjected to radiation, if desired; further applying a resinous coating composition containing ethylenically unsaturated groups in a specific amount to form a topcoat layer on the undercoat layer; and then curing the topcoat and undercoat layers with radiation to obtain the integrated, cured coating.
