ABSTRACT:
This invention provides both a pigment dispersing resin which is a copolymer of:(A) 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;(B) nonionic polymerizable unsaturated monomer having polyoxyalkylene chain;(C) ultraviolet-absorbing polymerizable unsaturated monomer and/or an ultraviolet-stabilizing polymerizable unsaturated monomer; and(D) other ethylenically unsaturated monomer, and water-based pigment dispersion which comprises said pigment dispersing resin, pigment, aqueous medium and, as circumstances may demand, dispersing agent as well.
