Color changing compositions
First Claim
1. A multiple coloring composition system comprising:
- (a) a first aqueous coloring composition comprising a first dye whose coloring ability is destroyed in the presence of a bleach; and
(b) a second aqueous coloring composition comprising from about 1% to about 20% by weight of a bleach; and
from about 0.1% to about 12% by weight of a colorant capable of maintaining its characteristic color in the presence of a bleach.

Abstract
A multiple coloring composition system is disclosed whose coloring effect is changed upon treatment with a second coloring composition, once the second coloring composition has been deposited over the first coloring composition. The multiple ink system comprises:
(a) a first aqueous coloring composition comprising a first dye whose coloring ability is destroyed in the presence of a bleach; and
(b) a second aqueous coloring composition comprising from about 1% to about 20% by weight of a bleach; and from about 0.1% to about 12% by weight of a colorant capable of maintaining its characteristic color in the presence of a bleach and/or a pH of about 10 or greater.
The multiple coloring composition may further comprise a base in an amount sufficient to elevate the pH of the second aqueous coloring composition to a level of from about 10 to about 12.
