<p>Disclosed are olymeric dye of formula (1a), (1b), (1c), A and B, independently from each other represent a polymer backbone; X1 and X2 independently from each other are a linkage group selected from—C1-C30alkylene- or—C2-C12alkenylene-, which is interrupted and/or terminated at one or both ends by one or more than one—S—,—N—,—N═—,—N(R5)—,—S(O)—,—SO2—,—(CH2CH2—O)1-5—,—(CH2CH2CH2—O)1-5—,—C(O)—,—C(O)O—,—OCO—, (II),—CON(R1)—,—C(NR1R2)2—,—(R1)NC(O)—,—C(S)R1—; or an optionally substituted, saturated or unsaturated, fused or non-fused aromatic or nonaromatic (heterocyclic) bivalent radical optionally comprising at least one heteroatom; a saturated or unsaturated, fused or non-fused aromatic or nonaromatic bivalent radical comprising at least one heteroatom, which is optionally substituted by C1-C30alkyl, C1-C30alkoxy, C2-C12alkenyl, C5-C10aryl, C5-C10cycloalkyl, C1-C10alkyl(C5-C10arylene), hydroxy or halogen; R1 and R2 independently from each other are hydrogen; unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl); Y1 and Y2 independently from each other are a residue of an organic dye; or hydrogen; wherein at least one of Y1 and Y2 is a residue of an organic dye; An1, An2 and An3, independently from each other are an anion; a and b independently from each other are a number from 1 to 3; m is a number from 0 to 5000; n is a number from 0 to 5000; and p is a number from 1 to 5000; wherein the sum of m+n+p≧3. 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.</p> |
