Estimating the term…
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.
A fluid colorant for tinting an unpigmented or pigmented coating composition, the colorant containing less than a continuous film-forming amount of a film-forming polymeric binder, and the colorant comprising:
A colored latex coating composition comprising a film-forming latex polymer binder, water, solid pigment particles, and 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 and having a molar equivalent weight per reactive unsaturated site that is less than 500 grams (g), at least one molecular species in the reactive liquid diluent containing at least one reactive unsaturated site as well as at least one hydrophilic segment that enables such species to stably disperse the pigment particles in the coating composition.
