  • Patent number: 6683121
    Abstract: A pigment dispersant including 80-97% by weight, based on the weight of thepigment dispersant, of a first polymer comprising as copolymerized units 15-75% by weight, based on the first polymer weight, ethylenically unsaturated carboxylic acid-functional monomer, the polymer having a Mw from 4,000 to 16,000, and the polymer having a Tg greater than 70° C.; and 3-20% by weight, based on the weight of the pigment dispersant, of a poly(ethylene oxide/propylene oxide) block second polymer having an Mw from 3,000 to 20,000 and an HLB value of 16 to 32 is provided. And the invention relates to a method for dispersing a pigment in an aqueous medium using the pigment dispersant, an aqueous pigment dispersion including the pigment dispersant, and an aqueous ink including the pigment dispersion.
