COATING COMPOSITION CURABLE WITH ULTRAVIOLET RADIATION

摘要

A clearcoat curable by ultraviolet radiation including at least one of A) acrylate or methacrylate monomers or mixtures thereof having from one to six free-radically polymerizable groups per molecule or B) compounds containing two or more ethylenically unsaturated, free radically polymerizable groups p er molecule and mixtures thereof or mixtures of A) and B). The coating may optionally include photoinitiators, volatile organic solvent(s) and customar y additives. The invention further provides a process for applying the clearco at to a substrate. In a preferred embodiment the process according to the prese nt invention includes low energy curing of a clearcoat applied to a substrate b y means of a UV light source utilizing UVA/UVV or UVA only and involves essentially no UVB or UVC radiation.
