<p>PURPOSE:To produce an inorganic pigment of excellent dispersibility, by mixing an inorganic pigment under agitation with a specified polymer. CONSTITUTION:An inorganic pigment (A) (e.g., white carbon) is mixed with a polymer (B) having at least one reactive group selected from among an aziridine group, an oxazoline group and an N-hydroxyalkylamide group in the molecule (e.g., styrene/isopropenyloxazoline copolymer) at an A to B ratio of 100/1-1,000 in the presence of, optionally, a polymeric substance and a dispersing medium such as an organic solvent at 0-350 deg.C.</p> |
