Abstract: A first pigment made of a coloring pigment having a primary average particle diameter of 200 nm or smaller or, or made of carbon black having an average particle diameter of a structure of 100 nm or smaller, and a second pigment made of barium sulfate having a primary average particle diameter of 55 nm or smaller are combined so that a value of (acid amount-base amount) of one pigment becomes positive, and a value of (acid amount-base amount) of other pigment becomes negative, and the combined first and second pigments are dispersed in a medium in the presence of a pigment dispersant.

Abstract translation: 由一次平均粒径为200nm以下的着色颜料或平均粒径为100nm以下的炭黑制成的第一颜料和由硫酸钡制成的第二颜料，具有 将一次平均粒径为55nm以下的组合使得一种颜料的（酸碱量）的值变为正，其他颜料（酸碱量）的值变为负， 并且在颜料分散剂存在下将第二颜料分散在介质中。
