The present invention relates to polymeric dyes of the general formula (1a), (1b) or (1c). Dyes are characterized by a depth of hue and good fastness to washing, e.g. fastness to sunshine, shampooing and rubbing.< EMI ID = 6.1 > < RTI ID = 0.0 > (Ib) < RTI ID = 0.0 > (1c) Wherein A and B each independently represent a polymer backboneXOneAnd X2Are each, independently of one another, COne-C30Alkyl, COne-C30Alkoxy, C2-C12Alkenyl, C5-C10Aryl, C5-C10Cycloalkyl, COne-C10Alkyl (C5-C10Arylene), at least one of-S-,-N-,-N =-,-N (R5)-,-S (O)-,-SO2-,-(CH2CH2-O)1-5-,-(CH2CH2CH2-O)1-5-,-C (O)-,-C (O) O-,-OCO-, ,-CON (ROne)-,-C (NROneR2)2-,-(ROne) NC (O)-,-C (S) ROne-or-C (O)-optionally interrupted and / or terminated by an optionally substituted, saturated or unsaturated, fused or non-fused aromatic or nonaromatic (hetero) cyclic bivalent radical optionally containing one or more heteroatomsOne-C30-alkylene or-C2-C12Alkenylene- Is a linking group selected from saturated or unsaturated, fused or non-fused aromatic or nonaromatic bivalent radicals comprising one or more heteroatomsROneAnd R2Are each independently of the other hydrogen Unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or non-interrupted COne-C14Alkyl C2-C14Alkenyl C6-C10Aryl C6-C10Aryl-COne-C10Alkyl Or C5-C10Alkyl (C5-C10Aryl)YOneAnd Y2Are each independently of the other an organic dye residue Or hydrogen Where YOneAnd Y2 is a residue of an organic dyeAnOne, An2And An3Are each, independently of one another, an anionA and b are each independently a number of 1 to 3M is a number from 0 to 5,000N is a number from 0 to 5000P is a number from 1 to 5000Where the sum of m + n + p is 3.본 발명은 하기 화학식 1a, 화학식 1b 또는 화학식 1c의 중합체성 염료에 관한 것이다. 염료는 색조의 깊이 및 우수한 세척 견뢰도, 예를 들면 일광, 샴푸질 및 문지름에 대한 견뢰도를 특징으로 한다.<화학식 1a><화학식 1b><화학식 1c>여기서 A 및 B는 각각 서로 독립적으로 중합체 주쇄를 나타내고X1 및 X2는, 각각 서로 독립적으로 C1-C30 알킬, C1-C30 알콕시, C2-C12 알케닐, C5-C10 아릴, C5-C10 시클로알킬, C1-C10 알킬(C5-C10
