    Abstract: A compound of formula (II) is useful as a UV absorber that possesses affinity for textile fibers in cellulosic textile materials. In formula (II): X is -CR1=CR2; R1 and R2 are independently H, alkyl, alkoxy, alkoxycarbonyl, acyloxy, carboxyl, cyano, nitro, F, Cl, Br, sulphonyl, alkylsulphonyl, or optionally substituted phenyl or R1 can also be -NQ-CO- which is bonded with its carbonyl carbon atom to the ortho position of the adjacent phenyl ring to form a benzopyrrolidine system; Q is H or alkyl; Z is alkyl, alkoxy, alkoxycarbonyl, acyloxy, carboxyl, cyano, Cl, F, Br, nitro, sulphonyl, alkylsulphonyl, amino, monoalkylamino, dialkylamino, optionally alkyl substituted carboxamido, or optionally saturated, 5 or 6 membered heterocyclic radical that can be optionally benzofused or any two adjacent Z radicals can form an optionally saturated 5 or 56 membered ring and if p is 0 an ortho disposed carboxyl group may be combined with the carbonyl group present and a nitrogen atom attached directly to this carbonyl group to form a cyclic imide; n is 1 to 3; p is 0 to 5; Y is a aliphatic, cycloaliphatic or mixed aliphatic-aromatic radical which has at least m' primary and/or secondary amino groups for forming amide bonds with the structural unit of formula (I) and the group Y can be also quaternized at the tertiary and/or free primary and/or secondary nitrogen atoms present or still present and m' is 1 to 200 where m if the structural units (I) accounts form 10 to 1000% if the m; provided that however at least one structural unit (I) is present in the compound of formula (II).
