PROBLEM TO BE SOLVED: To provide a dispersant which is used for dispersing a pulverized metallic compound particle in a monodisperse form or its similar form without making a secondary flocculation of the metallic compound particle in a highly concentrated state in an organic solvent.SOLUTION: This dispersant contains a chemical compound (A) with an alkali-reactive group represented by formula (1). In the formula (1), Ris a 2-22C alkyl group or alkenyl group; Ris a methylene group or a group represented by -CH=CH-CH-: Q is an alkali-reactive group; and X is at least one selected from the group consisting of hydrogen, a hydroxyl group and a group represented by -O-(AO)-CHCOOH. For the chemical compound (A) with the alkali-reactive group, chemical compounds such as a polyoxyalkylene alkyl ether acetic acid [in the formula (1), X is hydrogen; Ris a 2-22C alkyl group; Ris a methylene group; Q is a group represented by formula -O-(AO)n-CH2COOH; AO is a 2-4C oxyalkylene group and "n" is a number of 1 to 200], are cited. |
