の構成、効果等を具体的に説明する。That is, oxygen, nitrogen, and sulfur, which are the constituent elements of inorganic pigments, are bonded to zirconium atoms by treatment with zirconium soap, and the lipophilic residues that make up the zirconium soap are thereby exposed to the outside of the pigment particles. Placed. Therefore, the inorganic pigments treated by the method of the present invention are easily dispersed in organic media such as paints, lacquers, printing inks, plastics, crayons, etc., reducing the kneading time and at the same time preventing secondary agglomeration. This allows a stable dispersion state to be maintained. It has also been found that paints formulated with pigments treated according to the invention have excellent gloss and hiding power. EXAMPLES The structure, effects, etc. of the present invention will be specifically explained below with reference to Examples.
