Claim:
Polymeric dye obtained by the reaction of (a) a basic polycondensate with (b) an electrophilic dye of formula (2) P—X—Y a+ An a− ; wherein the basic polycondensate (a) is obtained by the reaction of (a 1 ) an amine of formula in the presence of an anhydrous solvent with an ammonium salt (a 2 ) with a cyanamide; wherein R 1 , R 2 , R 3 and R 4 independently from each other are hydrogen; or C 1 -C 4 alkyl, which may be substituted by amino, hydroxy, cyano or C 1 -C 4 alkoxy; A is C 2 -C 20 alkylene, 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 C 1 -C 30 alkylene, C 2 -C 12 alkenylene, C 5 -C 10 arylene, C 5 -C 10 cycloalkylene and C 1 -C 10 alkylene(C 5 -C 10 arylene) which may be interrupted and/or terminated at one or both ends by one or more than one —O—, —S—, —N═, —N(R 5 )—, —S(O)—, SO 2 , —(CH 2 CH 2 —O) 1-5 —, —(CH 2 CH 2 CH 2 —O) 1-5 —, —C(O)—, —C(O)O—, —OC(O)—, —CON(R 5 )—, —C(NR 5 R 6 ) 2 —, —(R 5 )NC(O)—, —C(S)R 5 — 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(R 5 )—; —S(O)—; —SO 2 —; —(CH 2 CH 2 —O) 1-5 —; —C(O)—; —C(O)O—, —OC(O)—; —CON(R 5 )—; —SO 2 N(R 5 )—; —C(NR 5 R 6 ) 2 —; —(R 5 )NC(O)—; —C(S)R 5 —; saturated or unsaturated, fused or non-fused aromatic or nonaromatic bivalent radical optionally comprising at least one heteroatom; which is optionally substituted by C 1 -C 30 alkyl, C 1 -C 30 alkoxy, C 2 -C 12 alkenyl, C 5 -C 10 aryl, C 5 -C 10 cycloalkyl, C 1 -C 10 alkyl(C 5 -C 10 arylene), halogen or hydroxy; or the direct bond; Y is a residue of an organic dye; R 5 and R 6 independently from each other are hydrogen; unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C 1 -C 14 alkyl; C 2 -C 14 alkenyl; C 6 -C 10 aryl; C 6 -C 10 aryl-C 1 -C 10 alkyl; or C 5 -C 10 alkyl(C 5 -C 10 aryl); a is 1, 2 or 3; and An is an anion.
