Abstract: The invention relates to a radiation curable coating which provides superior abrasion and chemical resistance and excellent adhesion properties. The coating is produced by radiation curing. A first monomer selected from the group consisting of triacrylates and tetracrylate mixed with a second monomer having an N-vinyl imido group, preferably an N-vinyl lactam, such as vinyl pyrrolidone or vinyl caprolactam. The monomer mixture is substantially oligomer-free and if the radiation is ultraviolet light, a photoinitiator, preferably p-phenoxydichloro acetophenone or dimethoxyphenyl acetophenone, is included in the mixture.

Abstract: A radiation curable coating comprising;A. an oligomer of Formula I: ##STR1## wherein: R.sup.1 is hydrogen or methyl;Y is a divalent urethane residue;B. an acrylic ultra-violet light absorber of Formula IV: ##STR2## wherein R.sup.4 is alkyl or hydroxy alkylene. Preferably the coating composition contains a vinyl monomer copolymerizable with the oligomer. The process for curing the coating is also disclosed.
