Process for preparing color dispersions and the color dispersions made thereof

1. A color dispersion comprising

a first colorant dispersion comprising, based on total weight of the first colorant dispersion,

from 0.05 wt. % to 10 wt. % of a first colorant;

from 0.1 wt. % to 15 wt. % of a first gel selected from methylcellulose, hydropropylmethylcellulose, hydroxyethylmethylcellulose, hydroxybutylmethylcellulose, hydroxyethylethylcellulose, and the mixture thereof; from

0.1 wt. % to 15 wt. % of a second gel selected from guar, pectin, carrageenan, gelatin, and the mixture thereof and

water; and a protective composition comprising, based on total weight of the protective composition,

from 0.5 wt. % to 70 wt. % of polymer particles;

from 0.1 wt. % to 10 wt. % of a clay; and

from 0.05 wt. % to 10 wt. % of a peptizing agent;

wherein the weight to weight ratio of the first colorant dispersion to the protective composition is from 1:10 to 10:1.

2. The color dispersion according to claim 1 wherein the first colorant dispersion further comprises, based on total weight of the first colorant dispersion, from

0.1 wt. % to 40 wt. % of polymer particles.

3. The color dispersion according to claim 1 wherein the first colorant dispersion further comprises, based on total weight of the first colorant dispersion, from 0.1 wt. % to 10 wt. % of a clay; and from 0.1 wt. % to 40 wt. % of polymer particles.

4. A color coating comprising the color dispersion according to claim 1 .

5. A process for making a color dispersion 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;

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, from 0.1 wt. % to 15 wt. % of the first gel, and from 0.1 wt. % to 15 wt. % of the second gel; 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 protective composition comprises based on the total weight of the protective composition, from 0.5 wt. % to 70 wt. % of the polymer particles, from 0.1 wt. % to 10 wt. % of the clay, and from 0.05 wt. % to 10 wt. % of the peptizing agent wherein the weight to weight ratio of the first colorant dispersion to the protective composition is from 1:10 to 10:1.

6. The process according to claim 5 wherein the first step further comprises contacting from 0.1 wt. % to 10 wt. % based on total weight of the first colorant dispersion, of a clay, to form the first colorant dispersion.

7. The process according to claim 5 wherein the first step further comprises contacting from 0.1 wt. % to 40 wt. % based on total weight of the first colorant dispersion, of polymer particles, to form the first colorant dispersion.

8. The process according to claim 5 wherein the first step further comprises contacting based on total weight of the first colorant dispersion, from 0.1 wt. % to 10 wt. % of a clay; and from 0.1 wt. % to 40 wt. % of polymer particles, to form the first colorant dispersion.

9. The process according to claim 5 further comprising

a 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.

10. The process according to claim 9 further comprising

a fourth step of mixing the dispersions of protected first and second colorant particles to form a two-color dispersion.
