NONAQUEOUS DISPERSANT AND NONAQUEOUS DISPERSION COMPOSITION

摘要

The present invention provides a non-aqueous dispersant capable of dispersing fine dispersant particles among a non-aqueous solvent at a high concentration, and assigning excellent dispersion stability at the same time. In addition, a non-aqueous dispersant represented by chemical formula (1) is provided. In chemical formula (1), R is a straight or branched chain hydrocarbon group with the number of carbons of 1 to 22, AO is an oxyethylene group, m is 1 to 30, AO is an oxyalkylene group with the number of carbons of 3 to 4, n is 1 to 30, wherein the relation of 0.1 = m / n = 10 and 5 = m + n = 40 are satisfied, a is the number of aromatic rings and is 1 to 2, and M represents a hydrogen atom, and ammonium or alkanol ammonium.
