Composition for oxidation dyeing of keratinic fibers comprises: (a) at least one developer selected from p-phenylenediamine derivatives (I) of formula (I); and (b) at least one polymer selected from amphoteric polymers, cationic polymers comprising repeat units of formulae (II) or (III) and polymers having fatty chains: 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; alternatively: (a) R1 and R2 = (CH2)2CHOHCH2OH; or (b) 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 (c) 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. R5-R8 = 1-20C aliphatic, alicyclic or araliphatic groups, lower hydroxyalkyl, or 1-6C alkyl substituted by a nitrile, ester, amide, CO-O-R13-D or CO-NH-R13-D group, or together with their N atoms form heterocycles optionally containing a second heteroatom other than N, or R5 and R7 can be linked to complete a piperazine ring; R13 = alkylene; D = quaternary ammonium; A1, B1 = 2-20C (un)saturated alkylene optionally containing one or more aromatic rings or O or S atoms or SO, SO2, disulfide, amino, alkylamino, hydroxy, quaternary ammonium, ureido, amide or ester groups, or B1 can be (CH2)n-CO-T-CO-(CH2)n when A1 is (un)saturated alkylene or hydroxyalkylene; X1 = an anion; T = -O-Z-O-, a bis-secondary diamine residue, -NH-Y-NH- or -NH-CO-NH-; Z = (CH2CH2O)xCH2CH2 or (CH2CHMeO)yCH2CHMe; x, y = 1-4; Y = a linear or branched hydrocarbon group or CH2CH2SSCH2CH2; R9-R12 = H, Me, Et, Pr, 2-hydroxyethyl, 2-hydroxypropyl or CH2CH2(OCH2CH2)pOH, but not all H; p = 0-6; r, s = 1-6; q = 0-34; A = a dihalide residue or CH2CH2OCH2CH2; X2 = an anion. |
