Aqueous pigment preparation, useful e.g. for coloring macromolecular material e.g. synthetic material, comprises an organic and/or inorganic pigment and a dispersant

摘要

Aqueous pigment preparation comprises at least an organic and/or inorganic pigment; and at least a dispersant, which is two or more phenol compound (I) that are bonded to the structural unit Y 1. Aqueous pigment preparation comprises at least an organic and/or inorganic pigment; and at least a dispersant, which is two or more phenol compound of formula (I) that are bonded to the structural unit Y 1. a, c : 1-100; b : 0-100; R 2an aliphatic, linear or branched 1-30C hydrocarbon; A : H or anions such as -SO 3M, -SO 2M, -PO 3M 2, -CH 2COOM or CH 2-C(O)-CH 2-CH(SO 3M)-C(O)-OM; M : H or cation such as Na +, K +, NH 4+, ethanol ammonium, diethanolammonium or triethanolammonium, or secondary-, tertiary or quaternary alkyl substituted ammonium; and Y 1a carbon containing structural unit that exhibits at least two bonding places for alkoxylation, and the bonding places are formed by one or more nitrogen atoms and/or oxygen atoms. Where a, b and c are arranged statistically or block-by-block. Independent claims are included for: (1) a method for dispersing at least an organic and/or inorganic pigment in water comprising mixing organic and/or inorganic pigment and aqueous dispersant; and (2) a dispersant containing two or more structural units of (I).
