摘要 PCT No. PCT/EP86/00674 Sec. 371 Date Jul. 27, 1987 Sec. 102(e) Date Jul. 27, 1987 PCT Filed Nov. 22, 1986 PCT Pub. No. WO87/03474 PCT Pub. Date Jun. 18, 1987.Oxidative hair dye composition based on 4-amino-2-aminomethyl-phenols of the general formula (I) <IMAGE> (I) or its salts as developer substances, wherein R1 and R2 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 R1 and R2 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) <IMAGE> (XII) wherein Ra 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 Rb equals aminoalkyl, mono- or dialkylaminoalkyl, acylaminoalkyl, aryl- or alkylsulfonylaminoalkyl, carboamoyl, carbamidoalkyl, acyl, aryl- or alkylsulfonyl-wherein the alkyl radicals have 1 to 4 carbon atoms in each instance. The developer substances of the formula (I), while having equally good dyeing behavior, have properties which are better physiologically than the p-aminophenol chiefly used previously for colorings in the red area.
