Abstract (en)

[origin: US2006282959A1] The present invention is a novel gel-phase colorant dispersion comprising (a) a gel-phase colorant comprising the reaction product of (1) a reactive material component, (2) a reactive colorant, and (3) a crosslinker having reactive groups capable of forming a bond with the reactive material component and the reactive colorant; and (b) a dispersion medium, wherein the dispersion medium can be an aqueous or non-aqueous-based dispersion. The gel-phase colorant dispersion of this invention can then be mixed or blended with typical coating materials. This invention is also directed to a method of preparing coating compositions comprising a binder phase of an aqueous or non-aqueous-based dispersion and a gel-phase colorant dispersion, and in particular, a method comprising the steps of (1) preparing at least one gel-phase colorant dispersion comprising a gel-phase colorant comprising a reaction product of (a) a reactive material component, (b) a reactive colorant, and (c) a crosslinker having reactive groups capable of forming a bond with the reactive material component and the reactive colorant; dispersed in a dispersion medium; and (2) mixing or blending the gel-phase colorant dispersion with typical coating materials. The coating composition can also comprise one or more independent gel-phase colorant dispersions. This invention is also directed to a process for achieving a multicolor faux finish pattern on a surface utilizing a gel-phase colorant dispersion-based one-pack multiphase coating composition. This invention is also directed to a two-layer coating system comprising a topcoat and an undercoat, wherein the topcoat is a waterborne dispersion comprising a gel-phase colorant dispersion comprising a gel-phase colorant comprising a reaction product of: (1) a reactive material component, (2) a reactive colorant, and (3) a crosslinker having reactive groups capable of forming a bond with the reactive material (a) component and the reactive colorant; and (b) a dispersion medium and wherein the undercoat is a waterborne dispersion comprising one or more highly water-absorbent pigments.
