A paint that provides a textured surface when polymerized on a substrate by ionizing radiation which, exclusive of pigments and particulate mineral filler, consists essentially of a solution of a volatile, inert, organic solvent and a mixture including: (1) an alpha-beta olefinically unsaturated organic resin containing between about 0.5 and about 5 units of unsaturation per 1000 units of molecular weight; and (2) vinyl monomers in which the unsaturated organic resin has limited solubility, i.e., between about 1 and about 15 weight percent based on the weight of the monomer and which will copolymerize with the unsaturated organic resin upon exposure to ionizing radiation. The unsaturated organic resin and monomer are dissolved in the volatile, inert, organic solvent which is a mutual solvent for both the monomer and the prepolymer and applied to a substrate. After evaporation of the inert solvent, the coating is irradiated and polymerizes to form a textured coating. |
