Document Type and Number:
Japanese Patent JP3390153
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain the subject composition where the fine-particle dispersed system is excellent in long-term preservation stability, stability in a temperature change cycle ranging from a high temperature to freezing, etc., by including pigment, a dispersant composed of a specific derivative and an aqueous medium.
SOLUTION: The objective composition is obtained by including (A) pigment, (B) a dispersant composed of a polyoxyethylene alkyl ethereal sulfate derivative of the formula: RO(CH2CH2O)nSO3M (R is a 10-20C alkyl or alkenyl; M is ammonium, organic amines, alkanolamines or an alkali metal; and n is an average polymerization degree of oxyethylene chain and is 2 to 50) and (C) an aqueous medium. The ingredient A used is preferably C.I.Pigment Black 7, C.I.Pigment Red 122, C.I.Pigment Violet 19, aluminum phthalocyanine, C.I.Pigment Blue 15:3, C.I.Pigment Yellow 55, etc.
