ABSTRACT:
A low dosage electron beam radiation polymerizable protective and decorative coating composition or paint with improved weatherability, coated articles bearing such a protective coating and processes for preparing such articles. The radiation polymerizable coating composition comprises an organic resin/monomer mixture of:
(A) between about 97 and about 3 weight percent alpha-beta olefinically unsaturated organic resin containing between about 0.5 and about 5 vinyl unsaturation units per 1000 molecular weight of said resin; and
(B) between about 3 and about 97 weight percent vinyl monomers polymerizable with said resin upon exposure to radiation, characterized in that said vinyl monomers include N-vinyl-2-pyrrolidone in an amount of between about 3 and about 20 weight percent based on the total weight of (A) and (B); and
(C) about 0.5 to about 5.0 parts each per 100 parts of the total of said organic resin and said monomer of:
