AQUEOUS CARBON BLACK DISPERSION, ITS PRODUCTION AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide a carbon black dispersion which does not blot and has good storage stability. SOLUTION: This aqueous carbon black dispersion contains carbon black and a cationic surfactant in amounts of 1 to 45 wt.% and 1 to 40 wt.%, respectively, based on the total amount of the aqueous dispersion in addition to water. The aqueous carbon black dispersion in which the cationic surfactant is a compound of the general formula (3) R1-COOH is ricinoleic acid; R2 to R4 are each independently a 1 to 5C alkyl or a group of the formula [R5 is a 1 to 5C alkyl; (n) is a natural number of 1 to 5]}.
