摘要： A washable 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 undercolor coloring composition. The washable multiple ink system comprises:(a) an undercolor aqueous coloring composition comprising a compatable surfactant in an amount sufficient to provide washability and an undercolor dye whose coloring ability is destroyed in the presence of a pH of about 10 or greater and/or by a reducing agent; and(b) an overcolor aqueous coloring composition comprising a compatable surfactant in an amount sufficient to provide washability, a colorant capable of maintaining its characteristic color in the presence of a pH of about 10 or greater and/or a reducing agent, a base in an amount sufficient to yield a pH of the overcolor composition of about 10 or greater, and/or a reducing agent.
