ABSTRACT:
A coloring system for temporarily or permanently dyeing fibers uses polyhydric alcohols to soften starch and cellulose derivatives in an organic acid solution to form glycolate modofied derivatives. Hydrophobic pigment particles are mixed with the glycolate modified derivatives after reducing the acidity of the solution with a base, resulting in a water removable temporary dye system that may be converted into a permanent dye by adding a latex suspension.
