Abstract
Abstract A radiation-curable paint which on a pigment and particulate filler-free basis consists essentially of vinyl monomers and an alpha-beta olefinically unsaturated, elastomeric particle of crosslinked acrylic polymer. The coating is applied as a filmforming dispersion to the surface of a substrate and cured thereon by ionizing radiation, e.g., an electron beam. This application is further directed to articles of manufacture coated with this paint using this process of curing.
