Couplers having the general formula (I): ##STR1## or the acid salts thereof in which formula R is either (a) hydrogen or (b) a C.sub.1 -C.sub.3 alkyl or (c) a C.sub.1 -C.sub.3 hydroxyalkyl, and Z is either (a) hydroxyalkyl, or (b) alkoxyalkyl in which the alkoxy group contains 1 to 2 carbon atoms, or (c) mesylaminoalkyl, or (d) acetylaminoalkyl, or (e) ureidoalkyl, or (f) carbethoxyaminoalkyl the alkyl groups in the radicals constituting Z comprising from 2 to 3 carbon atoms and Z is not hydroxyethyl when R is hydrogen. These couplers form dyeing compositions when mixed with an oxidation base consisting of a paraphenylenediamine having the general formula: ##STR2##
