| titleOfInvention | Polymeric hair dyes |
| abstract | Disclosed are polymeric dyes obtained by the reaction of (a) a basic polycondensate with (b) an electrophilic dye of formula (2) P-X-Ya+ Ana-; wherein the basic polycondensate (a) is obtained by the reaction of (a1) an amine of formula (I) in the presence of an anhydrous solvent with an ammonium salt (a2) with a cyanamide; wherein R1, R2, R3 and R4 independently from each other are hydrogen; or C1-C4alkyl, which may be substituted by amino, hydroxy, cyano or C1-C4alkoxy; A is C2-C20alkylene, which may be substituted or interrupted by one or more than one hetero atoms; P is a reactive grouping capable of reacting with a nitrogen nucleophile; X is a linkage group selected from C1-C30alkylene, C2-C12alkenylene, C5-C10arylene, C5- C10cycloalkylene and C1-C10alkylene(C5-C10arylene) which may be interrupted and/or terminated at one or both ends by one or more than one -O-, -S-, -N=, -N(R5)-, -S(O)-, SO2, -(CH2CH2-O)1-5-, -(CH2CH2CH2-O)1-5-, -C(O)-, -C(O)O-, -OC(O)-, (II), -CON(R5)-, -C(NR5R6)2-, -(R5)NC(O)-, -C(S)R5- or an optionally substituted, saturated or unsaturated, fused or non-fused aromatic or nonaromatic (hetero)cyclic bivalent radical optionally comprising at least one heteroatom; -O-; -S-; -N(R5)-; -S(O)-; -SO2-; -(CH2CH2-O)1-5-; -C(O)-; -C(O)O-, -OC(O)-; (III); -CON(R5)-; -SO2N(R5)-; -C(NR5R6)2-; -(R5)NC(O)-; -C(S)R5-; saturated or unsaturated, fused or non-fused aromatic or nonaromatic bivalent radical optionally comprising at least one heteroatom; which is optionally substituted b |
