<p>PURPOSE:To obtain the titled aqueous dispersion, having stable dispersibility, free from the coagulation and precipitation of the particles of the dye or pigment during storage, by using a polymer containing a specific unit as a dispersant. CONSTITUTION:The objective aqueous dispersion contains a dispersant comprising at least one kind of the polymer containing >=5mol% unti of formula I {Q is benzene ring or naphthalene ring; alpha is -A-R1; beta is -D-X-Y or -D-Y [A and D are single bond or bivalent linking group; R1 is 1-30C (substituted) alkyl, alkenyl or aryl; X is (substituted) alkylene, arylene, etc.; Y is -COOM, -SO3M, -O-SO3M, or group of formula II (M is H<+> or cation)]; R2 and R3 are the numbers of substituted alpha and beta; m1 is 1-3; m2 is 1 or 2}.</p> |
