    摘要: A colloidal pigment dispersion composition comprising: water; dispersed pigment particles; a first polymer dispersant comprising units derived from an acrylate or methacrylate monomer having an alkyl group with 12 or more carbons and units derived from an ethylenicaly unsaturated monomer comprising a carboxylic acid substituent; and a second polymer dispersant comprising units derived from a monomer comprising an aromatic group containing substituent and units derived from an ethylenicaly unsaturated monomer comprising a carboxylic acid substituent, wherein the second polymer dispersant does not comprise units derived from an acrylate or methacrylate monomer having an alkyl group of 12 or more carbons, and wherein the second polymer dispersant has an acid number less than 270.
