Abstract
Dye compositions, especially for human hair containing the new chemical compounds of the general formula ##STR1## in which formula the radical Z is selected in the group formed by the hydroxyalkyl, alkoxyalkyl, acylaminoalkyl, carbalkoxyaminoalkyl, mesylaminoalkyl, ureidoalkyl, aminoalkyl, monoalkylaminoalkyl, dialkyl-aminoalkyl radicals, and the salts of the corresponding acids. Among the preferred acid salts, the sulfates, hydrochlorides, phosphates and tartrates may be mentioned. This dye is particularly suited for use with a coupler of the formula ##STR2## in which formula R.sub.3 and R.sub.4 are identical or different and may represent a hydrogen atom, alkoxy radical, or an alkyl radical and in which R.sub.5 is a radical selected in the group formed by the acyl, carbalkoxy and ureido radicals.
