Abstract
Abstract Fugitive colorants having the general formula: A--N═N--B--[(C)H].sub.n wherein A is thiophene or a thiophene derivative, N is nitrogen, B is a nitrogen containing organic dyestuff coupling component, C is a polymer chain bound to nitrogen in the dyestuff coupling component; said polymer chain being selected from polyethylene oxide, polypropylene oxide, polybutylene oxide and copolymers of polyethylene oxide, polypropylene oxide, and/or polybutylene oxide, said polymer chain having about x repeating monomeric units, n is an integer from 1 to 6 and the product of n times x is from about 50 to about 250. A coloration process is also disclosed and claimed.
