Abstract: Composition for oxidation dyeing of keratinic fibers comprises at least one developer selected from p-phenylenediamine derivatives (I) and at least one polymer selected from amphoteric polymers, cationic polymers and polymers having fatty chains.  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.
