Abstract:
A pigment dispersion useful for forming coating compositions containing dispersed pigment, a carrier solvent and an aminated macromonomer dispersant (binder) is disclosed. The aminated macromonomer dispersant is preferably prepared by the reaction of terminally unsaturated macromonomers synthesized by cobalt-catalyzed chain transfer free radical polymerizations of methacrylic monomers with monomeric or oligomeric amines.
