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.
