ACTIVE ENERGY RAY-CURABLE AQUEOUS DISPERSION

摘要

PURPOSE: To obtain an active energy ray-curable aqueous dispersion used for coating compositions giving coating films excellent in adhesiveness and chemical resistance such as solvent and alkali resistances by dispersing the microgel particles of an active energy ray-curable polyurethane resin in water. CONSTITUTION: This dispersion is obtained by dispersing in water the coating film-forming polyurethane resin microgel particles having active energy ray- curable unsaturated double bonds and salt groups and comprising one or more kinds of polyurethane resin skeletons selected from among polyester-, polyether(polyester)-, and polycarbonate-polyurethane resin skeletons and a cross-linked structure wherein the skeletons are cross-linked to each other through urethane bonds or urea bonds.
