A low dosage radiation polymerizable protective and decorative coating composition or paint, coated articles bearing such a protective coating and processess 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 alphabeta 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 from about 3 and up to about 10 weight percent based on the total weight of (A) and (B). The flexible coating exhibits excellent physical qualtities and good adhesion to a variety of substrates being particularly suitable for use on vinyl chloride fabric, wherein it is discoloration resistant after heat aging. Preferred articles bearing such a coating, which may comprise large amounts of pigment, are preferably cured by exposure to electron beam radiation.
