A pigment dispersion with improved rheology useful for forming solventborne paint compositions is disclosed. The dispersion comprises a copolymer pigment dispersant having at least one quaternary ammonium functional group; a pigment having a pH below 7.0; and an organic liquid carrier. The dispersion ...
All the particles may be embedded below the surface of the support substrate, or some of the particles may protrude above the surface of the support substrate. In one embodiment of the present invention, the support substrate contains particles that are dispersed only close to its surface and ...
