Abstract
Abstract The dissolution of certain low molecular weight vinyl resins in radiation curable compositions of one or more polyfunctional polymerizable reactive solvent and, optionally, one or more monofunctional reactive solvent yields compositions having better adhesion to metals than is obtained with the same composition without the vinyl resins and with better stain and abrasion resistance than could be obtained with the vinyl resins alone. The low molecular weight vinyl polymer is preferably a vinyl acetate polymer having an inherent viscosity below about 0.25 and a glass transition temperature from about 25 DEG C. to about 55 DEG C.
