Published June 12, 2008
Patent No. U.S. 7,271,213
Kansai Paint Co. has obtained a patent for a water-based pigment dispersion comprised of a pigment dispersing resin, pigment, aqueous medium, other pigment dispersing resin and, optionally, dispersing agent. The pigment dispersing resin being a copolymer of polymerizable unsaturated monomer containing at least one kind of ionic functional group selected from the group consisting of tertiary amino group, quaternary ammonium salt and sulfonic acid group; nonionic polymerizable unsaturated monomer having polyoxyethylene chain; ultraviolet-absorbing polymerizable unsaturated monomer and/or ultraviolet-stabilizing polymerizable unsaturated monomer; and other ethylenically unsaturated monomer, the copolymer being a copolymerization product of 0.5-30% by weight of ionic function group-containing polymerizable unsaturated monomer, 5-40% by weight of nonionic polymerizable unsaturated monomer, 0.1-5% by weight of ultraviolet-stabilizing polymerizable unsaturated monomer and 25-94.4% by weight of other ethylenically unsaturated monomer on the basis of the total weight of the monomers, the other pigment dispersing resin being selected from the group consisting of acrylic resin having a weight average molecular weight within a range of 2,000-150,000, an acid value in a range of 5-150 and a hydroxyl value in a range of 10-160, and polyester resin having a weight average molecular weight within a range of 1,000-100,000, an acid value in a range of 5-150, and a hydroxyl value in a range of 10 to 160.
