    Abstract: A process for preparing color dispersions comprising a first step of contacting water, a first colorant, and a gel composition comprising a first gel selected from methylcellulose, hydropropylmethylcellulose, hydroxyethylmethylcellulose, hydroxybutylmethylcellulose, hydroxyethylethylcellulose, and the mixture thereof, and a second gel selected from guar, pectin, carrageenan, gelatin, and the mixture thereof, to form a first colorant dispersion; a second step of contacting the first colorant dispersion with a composition comprising an aqueous dispersion of polymer particles, clay, and a peptizing agent to form a dispersion of protected first colorant particles. A color dispersion comprising the first colorant dispersion and a color coating comprising the color dispersion.

    Abstract: This invention relates to a process for preparing color dispersions comprising a first step of contacting water, a first colorant, and a polysaccharide selected from methylcellulose, hydropropylmethylcellulose, hydroxyethylmethylcellulose, hydroxybutylmethylcellulose, hydroxyethylethylcellulose, and the mixture thereof, to form a first colorant dispersion; a second step of contacting the first colorant dispersion with a protective composition comprising an aqueous dispersion of polymer particles, clay, and a peptizing agent to form a dispersion of protected first colorant particles; an optional third step of repeating the first step and the second step with a second colorant that is different from the first colorant to form a dispersion of protected second colorant particles; and an optional fourth step of mixing the dispersions of protected first and second colorant particles to form a multi-color dispersion. This invention also relates to a color dispersion comprising the first colorant dispersion, and a color coating comprising the color dispersion.
