Abstract: A coating composition comprises a urethane resin, a water absorbent polymer, and a curing agent. The urethane resin is obtained by reaction of an isocyanate reactive compound having multi-epoxide functionality and an isocyanate. When applied to a substrate and thermally cured, the coating composition forms a transparent and smooth coating having permanent anti-fog property.

Abstract: The present disclosure provides a coating composition comprising an initiator, a radical curable polyurethane having ethylenically unsaturated functional groups, and a liquid phase, wherein the radical curable polyurethane having ethylenically unsaturated functional groups comprises the reaction products of A) a polyol component; B) a polyisocyanate component; C) an isocyanate-reactive surfactant; and D) isocyanate-reactive component having ethylenically unsaturated functional groups. The resulting cured polyurethane coating resists surface damage by fine particles and has at least washable anti-fog properties, if not permanent anti-fog properties. Articles prepared with a coating according to this invention are also disclosed.
