Abstract:
PROBLEM TO BE SOLVED: To provide a nickel-rutile multiphase pigment which has advantageous use characteristics, especially a high color density. SOLUTION: A nickel-antimony-rutile multiphase pigment having a molar ratio of nickel to tungsten of 4 or higher is used for coloring plastics, coating materials, printing inks, and ceramic grazes. The pigment is prepared by perfectly mixing oxides or hydroxides of titanium, nickel, and antimony or salts of these metals convertible into oxides and baking the resultant mixture at 900-1,200 deg.C in an oxidizing atmosphere.
