摘要：Composition (A) for dyeing keratin fibers comprises, in a cosmetic medium, atleast one diheteroarylmethane compound (X) in quinoid or reduced form. Composition(A) for dyeing keratin fibers comprises, in a cosmetic medium, at least one
diheteroarylmethane compound (X) in quinoid or reduced form, of formulae (I), (Ibis), (II)or (IIbis), or their tautomers or addition salts. A = oxygen, NH or N-(hydroxy)alkyl; HET1and HET2 = heterocycle, optionally substituted by one or more Z'; R1 to R6 and Z' =halo, NHSO3H, hydroxy, alkyl, alkoxy, alkylthio, amino (optionally substituted by 1 or 2alkyl, optionally fused to form a ring that may be interrupted by one or more atoms ofnitrogen, oxygen or sulfur), heterocycles, nitro, aryl, acyl, alkoxycarbonyl, carboxamido,cyano, carboxy, SO3H, PO3H2 or PO4H2; A' = hydroxy, amino (optionally substituted by 1or 2, same or different alkyl and/or hydroxyalkyl, optionally forming a ring as above); R =hydrogen, halo, hydroxy, alkoxy or alkylthio.
