Abstract
Oxidative hair dye composition based on 4-amino-2-aminomethyl-phenols of the general formula (I) ##STR1## or its salts as developer substances, wherein R.sup.1 and R.sup.2 represent independently of one another hydrogen, alkyl, hydroxyalkyl, aminoalkyl, mono- or dialkylaminoalkyl, acylaminoalkyl, aryl- or alkylsulfonylaminoalkyl, carbamindoalkyl, acyl, aryl- or alkylsulfonyl or carbomoyl--wherein the alkyl radical has 1 to 4 carbon atoms in each case--or a heterocyclic, non-aromatic five- or six-membered ring is formed by means of R.sup.1 and R.sup.2 which can have an oxo group in addition. The subject matter of the application is also the new developer substances of the general formula (XII) ##STR2## wherein R.sup.a equals hydrogen, alkyl, hydroxyalkyl, aminoalky, mono- or dialkylaminoalky, acylaminoalkyl, aryl- or alkylsulfonylaminoalkyl, carbamoyl, carbamido-alkyl, acyl, aryl- or alkylsulfonyl--wherein the alkyl radicals have 1 to 4 carbon atoms in each instance--and R.sup.b equals aminoalkyl, mono- or dialkylaminoalkyl, acylaminoalkyl, aryl- or alkylsulfonylaminoalkyl, carbamoyl, carbamidoalkyl, acyl, aryl- or alkylsulfonyl--wherein the alkyl radicals have 1 to 4 carbon atoms i…
