ABSTRACT:
A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of at least 1500 and has 2 to 97% by weight of a polymeric backbone and 97-2% by weight of macromonomer side chains attached to the backbone and wherein the graft copolymer has at least about 1 weight percent of an imid or urea functional dispersing substituent attached to the backbone, the macromonomer, or both the backbone and the macromonomer.
