Zusammenfassung:A pigment dispersion is disclosed comprising (a) at least one pigment and (b) a polymeric dispersant comprising residual units derived from polymerization of a mixture of monomers comprising (b1) at least one ethylenically unsaturated hindered amine light stabilizing monomer and (b2) at least one additional ethylenically unsaturated monomer different from monomer (b1). Coating compositions comprising the same are also disclosed as are substrates coated at least in part with such coatings.
