  • Anionic electrodepositable coating composition for pigment dispersed color filter
    Patent number: 5523340
    Abstract: An anionic electrodepositable coating composition for making pigment dispersed color filters comprising: (a) a pigment; (b) a first addition copolymer containing pyrrolidone and hydroxy groups; (c) a second addition copolymer containing carboxyl and hydroxy groups; and (d) a low molecular weight amine. The pyrrolidone-containing monomer can be N-vinyl-2-pyrrolidone or a pyrrolidone-containing acrylate-based monomer represented by the following formula: ##STR1## wherein R is hydrogen atom, or methyl or ethyl group, and n is an integer between 1.about.3. The first addition copolymer has a weight average molecular weight between 1,000 and 20,000 and is prepared from a monomer composition comprising about 0.5.about.90 mole percent of a pyrrolidone-containing unsaturated monomer and about 1.about.50 mole percent of a hydroxy-containing unsaturated monomer. The second addition copolymer has a weight average molecular weight between 5,000 and 60,000 and is prepared from a monomer composition comprising about 5.
