Abstract: Composition for oxidation dyeing of keratinic fibers comprises a first developer selected from p-phenylenediamine derivatives (I) and a second developer selected from heterocyclic developers, bifunctional developers, substituted p-aminophenols, o-aminophenols and p-phenylenediamine derivatives (II).  Composition for oxidation dyeing of keratinic fibers comprises a first developer selected from p-phenylenediamine derivatives of formula (I); R1  = CH2(CHOH)4CH2OH or (CH2CH2O)pR4:  R2, R4  = H, alkyl, aryl or heterocyclyl;  p  = 2-8;  R3  = halogen, alkyl, aryl, heterocyclyl, heterocyclyloxy, heterocyclylthio, CN, NO2, OF, COOH, SO3H, alkoxy, aryloxy, cyanoamino, amino, anilino, ureido, sulfamoylamino, mono- or dialkylsulfamoylamino, alkylthio, arylthio, alkoxycarbonylamino, sulfonamido, carbamoyl, mono- or dialkylcarbamoyl, silyl, silyloxy, aryloxycarbonylamino, imido, sulfinyl, phosphonyl, aryloxycarbonyl, acyl or SH, or multiple R3 groups can form a 3- to 6-membered ring; alkyl  = optionally substituted 1-25C linear, branched or cyclic alkyl;  alkoxy  = 1-25C linear, branched or cyclic alkoxy;  aryl  = 6-26C aryl optionally substituted by alkyl, substituted alkyl or alkoxy;  heterocyclyl  = mono- or polycyclic heterocyclyl in which each ring has 3-6 members and can contain one or more heteroatoms; n = 0-4; R1 and R2  = (CH2)2CHOHCH2OH; or R1 = alkyl, aryl or heterocyclyl and R2 = a (CH2)2 or (CH2)3 group (Q) that is attached to a C atom ortho to the NR1R2 group, provided that R1 or Q is substituted with a N-, O- or S-containing group when R1 is alkyl or aryl; or NR1R2 is a 5- to 7-membered ring substituted with at least one N-, O- or S-containing group; provided that: (1) the compound contains no more than 3 OH groups when NR1R2 is a ring; (2) when NR1R2 is 2-carbamoyl-1-pyrrolidinyl, then n is nonzero or the pyrrolidine ring has at least 2 substituents; (3) when NR1R2 is 2-hydroxymethyl-1-pyrrolidinyl and n = 0 or 1, then the pyrrolidine ring either has at least 2 additional substituents or has one additional substituent other than 4-OH, or when NR1R2 is 2-hydroxymethyl-1-pyrrolidinyl and n = 1, then R3 is not alkyl, hydroxyalkyl or polyhydroxyalkyl; (4) when R2 is Q, then either: (i) the ring formed by Q has a substituent in addition to R1; (ii) n is more than 1; (iii) R3 is aryl or heterocyclyl when n = 1; or (iv) R1 is aryl, heterocyclyl or substituted alkyl other than monohydroxyalkyl when n = 0 or 1. and a second developer selected from heterocyclic developers, bifunctional developers, substituted p-aminophenols, o-aminophenols and p-phenylenediamine derivatives of formula (II):  R5 = H, 1-4C alkyl, 1-4C hydroxyalkyl, 2-4C polyhydroxyalkyl, (1-4C)alkoxy(1-4C)alkyl, 1-4C alkyl substituted with a N-containing group, phenyl or 4-aminophenyl; R6 = H, 1-4C alkyl, 1-4C hydroxyalkyl, 2-4C polyhydroxyalkyl, (1-4C)alkoxy(1-4C)alkyl or 1-4C alkyl substituted with a N-containing group;  R7 = H, halogen, 1-4C hydroxyalkyl, 1-4C hydroxyalkoxy, acetylamino(1-4C)alkoxy, mesylamino(1-4C)alkoxy or carbamoylamino(1-4C)alkoxy; R8 = H, halogen or 1-4C alkyl; provided that R7 is not H, Cl or Me when R5, R6 and R8 are H.
