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.
