Abstract: This invention relates to colorant dispersion formulations containing the typical levels of pigment, dispersing agents, rheology modifiers, and other components conventionally employed in colorant dispersions, but in combination with various polyethylenimine derivatives, with or without the addition of a fatty acid modified polymer and/or an acrylic resin. These formulations combine good properties for the preparation of the colorant dispersion, as well as providing the final colored surface coating or other product with enhanced properties, notably improved adhesion of the pigment to the surface.

Abstract: An aqueous, non-settling, universal pearlescent, or nacreous pigment dispersion is provided for use in dispensing machines for the custom mixing in retail stores and trade sales of alkyd or solvent-thinned and water-based surface coatings. The non-settling pearlescent pigment dispersion employs a synthetic silicate, sodium lithium magnesium silicate, as the suspending agent. Also disclosed are methods for preparing the dispersion which incorporates one or more carriers, humectants, surfactants and other optional conventional additives.
