  • Grafted pigment dispersing polymeric additive and paint employing the same with improved hiding
    Patent number: 8895658
    Abstract: The present invention relates to a grafted pigment dispersing polymeric additive for opacifying pigments, prepared by polymerizing monomers in the presence of a polymeric pigment dispersant. The polymeric pigment dispersant has low molecular weight, high acid number and is dissolvable in alkali solution. When incorporated into paint compositions, hiding is improved with less opacifying pigments.
