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.

Claim (Index 1):
A process for making a transparent/semi-transparent color dispersion comprising\n a first step of contacting water, a first colorant, and a polysaccharide selected from methylcellulose, hydroxypropylmethylcellulose, and a mixture thereof to form a first colorant dispersion; wherein the first colorant dispersion comprises based on total weight of the first colorant dispersion, from 0.05 wt. % to 10 wt. % of the first colorant, and from 0.05 wt. % to 10 wt. % of the polysaccharide; and 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; wherein the composition comprises based on total weight of the protective composition, from 10 wt. % to 70 wt. % of the polymer particles, from 0.05 wt. % to 10 wt. % of the clay, and from 0.05 wt. % to 2 wt. % of the peptizing agent; wherein the weight to weight ratio of the first colorant dispersion to the protective composition is from 1:30 to 5:1; and wherein the transparent/semi-transparent aqueous color dispersion contains substantially no organic solvent.
