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 by C1-C30alkyl, C1-C30alkoxy, C2-C12alkenyl, C5-C10aryl, C5-C10cycloalkyl, C1-C10alkyl(C5-C10arylene), halogen or hydroxy; or the direct bond; Y is a residue of an organic dye; R5 and R6 independently from each other are hydrogen; unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted d-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl); a is 1, 2 or 3; and An is an anion. The dyes are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing.
