Abstract
A powder coating composition comprising a powdered solid ethylenically unsaturated material having a melting point from 60° to 120° C. obtained by reacting a polyisocyanate with an at least stochiometric amount of an alcoholic component comprising: at least a monovalent alcohol, a part of which bears an ethylenic unsaturation derived from acrylic acid or methacrylic acid, and optionally at least a monomeric polyol. This composition is useful for coating substrates.
