ABSTRACT:
A method for dispersing a pigment is disclosed, wherein the pigment is dispersed in a medium solution by using sintered zirconia beads having an average particle diameter of 40 to 192 .mu.m, a density of 5.9 g/cm.sup.3 or more, and a sphericity of 1.07 or smaller. The method is particularly useful for providing an excellent coating gloss when the medium solution is a binder for forming a paint or a coating composition or a binder for forming an ink composition.
