Abstract

Abstract Dye, especially for human hair that consists of the new chemical compounds of the general formula <IMAGE> (I) in which Z is selected in the group consisting of hydroxyalkyl, alkoxyalkyl, acylaminoalkyl, carbalkoxyaminoalkyl, mesylaminoalkyl, ureidoalkyl, aminoalkyl, monoalkylaminoalkyl, dialkylaminoalkyl radicals, and the salts of the corresponding acids. Among the preferred acid salts are the sulfates, hydrochlorides, phosphates and tartrates. This dye is particularly suited for use with metadiphenols, metaphenylenediamines, metaaminophenols as well as the couplers of the formula <IMAGE> (III) in which R3 and R4 are identical or different and may represent hydrogen, alkoxy, or alkyl and in which R5 is selected from the group consisting of acyl, carbalkoxy and ureido.
