PURPOSE:To prevent the solid particles from settling and separating in the conservation for a long period by incorporating a reaction product of both aliphatic amine or its alkylene oxide adduct and an isocyanate compd. or its modified material as an available component. CONSTITUTION:A stable nonaqueous solid dispersant is prepared by incorporating a reaction product which is obtained by allowing aliphatic amine or its alkylene oxide adduct to react with an isocyanate compd. or its modified material as an available component. As the aliphatic amine, aliphatic monoamine which is derivated from one or more kinds of mixtures of saturated or unsaturated fatty acid having a carbon chain length of 6-22C preferably 10-18C is preferable. An addition molar number of alkylene oxide is ordinarily regulated to 1-100mol preferably 1-70mol. If necessary, the other known surface-active agent can be incorporated to this dispersant.
