Abstract: Fluid concentrates, colorants and coating compositions contain solid pigment particles dispersed in a nonvolatilizing, reactive liquid diluent having a viscosity less than 1,000 cps and containing at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent may serve as one or more of a dispersing medium for the solid pigment particles, a carrier, a coalescent and a humectant, and may crosslink or otherwise cure to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder. Embodiments of the reactive liquid diluent can provide colorants and coating compositions having reduced levels of VOCs, conventional carriers, conventional dispersants, conventional coalescents and conventional humectants.

Abstract: A coating composition including a rheology modifier is described. The rheology modifier is a water-soluble polyurethane made by the condensation of a poly(alkylene glycol), a polyisocyanate and a compound including a polyalkoxylated chain and a hydrophobic end group. The composition demonstrates Leneta sag resistance of greater than about 14 and a Leneta flow and leveling of at least about 9, and a Stormer viscosity of less than about 120 Krebs units.

Abstract: A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and an alkali-swellable copolymer component. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical dispersant amounts, and subsequently enable formation of polymer-encapsulating pigment dispersions that, when used in coatings, provide good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions.
