Abstract
An ultraviolet curable coating composition for cationic electrodeposition applicable to metal plated materials which composition comprises 100 weight parts of acrylic resin containing 10 to 70% by weight poly-functional acrylate per se having 3 or more acryloyl groups and 90 to 30% by weight of a resin of molecular weight 2,000-30,000 having a cationic electrodeposition property, and 0.1-10 weight parts of 2 or more species of photopolymerization initiators which absorb ultraviolet radiation in a wavelength range of 300-400 nm, as effective ingredients. The coating composition can readily be deposited electrically on metal materials including plated products and plastic materials provided with electrical conductivity and cured by irradiation of ultraviolet radiation within a short period of time to give a dry coating film which is appreciable in adhesiveness to the plated materials and good in appearance. Particularly, since the ultraviolet irradiation can be carried out at ordinary temperature, the method can be applied to non-heat-resistant materials such as plastics provided with electrical conductivity.
