Abstract
Abstract A radiation-curable, film-forming paint binder is provided by mixing about 20 to about 80 parts by weight of (1) an alpha-beta olefinically unsaturated copolymer of vinyl monomers having molecular weight in the range of about 1,000 to about 25,000 and about 0.5 to about 5 units of alpha-beta olefinic unsaturation per 1,000 units molecular weight, and (2) an alpha-beta olefinically unsaturated siloxane containing about 3 to about 18 silicon atoms per molecule. The unsaturated siloxane is the reaction product of at least two molar parts of of a monomeric, monohydroxy ester of an alpha-beta olefinically unsaturated monocarbolylic acid, e.g., acrylates, methacrylates, crotonates, cinnamates, with one molar part of a siloxane wherein at least two silicon atoms have one valence satisfied by a hydroxyl group or an alkoxy group. Vinyl monomers may also be included in the paint dispersion.
