146 words
A process for dyeing a keratinaceous substrate comprising the step of contacting it with a formulation containing (a) at least one reactant which is a compound of formula I: wherein R₁ is independently H, C₁₋₆ alkyl, acetyl, benzoyl or phenyl; and R₂ amd R₃ are each independently H or alkyl, OH, NH₂, Halogen, NO₂ C₁₋₆ alkylphenyl, phenyl, alkoxy, hydroxyalkoxy, polyhydroxyalkyl, alkyl amino, hydroxyalkylamino, polyhydroxy alkylamino wherein all alkyl groups contain from about 1 to about 6 carbon atoms; with (b) at least one reactant which is of formula II: wherein R₂ and R₃ are independently H, alkyl, phenyl, substituted phenyl, hydroxy, alkoxy, trifluoromethyl, nitro, amino monoalkylamino, dialkylamino, monohydroxy-alkyl amine, polyhydroxyalkyl amino, aniline, bis(monohydroxy-alkyl)amine, bis(polyhydroxyalkyl) amino or C₁₋₆ carboxyaldehyde, wherein all alkyl groups contain from about 1 to about 6 carbon atoms; wherein the contacting step involves the use of (a) and (b) either simultaneously or sequentially.
Claim 2
Dependent Claim
146 words
