Patent ID: 8187340

Claim:
A functionalized dye comprising at least one chromophore and a color fastness moiety, wherein the chromophore is bound to the color fastness moiety by a linker, wherein said dye is a compound of formula Ia: C-L-F (Ia), wherein C is a chromophore of formula IIg: or C is a chromophore represented by the following structural formula: wherein R 7c is attached to linker L; R 7a , R 7b , R 7d , R 7e , R 7f , R 7g , R 7h , R 7i and R 7j are each independently hydrogen, hydroxyl, alkyl, alkenyl, alkynyl, aryl, amino, alkylammonium, sulfonyl, carbonyl, carboxy, alkoxy, aryloxy, halogen, acyl, oximyl, hydrazinyl, —NO 2 , —CN, a heterocyclic moiety or thioether; R 26a is attached to linker L; L is a linker of formula (III): wherein L covalently links the chromophore C via the left hand side of formula III to the color fastness moiety F via the right hand side of formula III; a, b, c, d, e, and f are each independently an integer from 0-2, provided that at least one of a, b, c, d, e and f is not 0; R 40 , R 41 , R 42 , R 43 , R 44 , R 45 , R 46 , R 47 , R 48 , R 49 , R 50 and R 51 are each independently absent or hydrogen; E is NR 52 or NR 53 C═O; R 52 and R 53 are each independently hydrogen or alkyl; the color fastness moiety is of formula (Va): wherein m, n, o, p, q and r are each independently an integer from 0-2, provided that at least one of m, n, o, p, q and r is not 0; R 78 ,R 79 , R 80 , R 81 , R 82 , R 83 , R 84 , R 85 , R 87 , R 88 and R 89 are each independently hydrogen or absent; R 86 is absent, hydrogen or hydroxyl; K is NR 90 , C(═O)NR 92 or OC═O; W is NR 95 R 96 , CR 97 R 98 R 99 or OR 100 ; R 90 and R 92 are each independently hydrogen or alkyl; R 95 is alkyl and R 96 is hydrogen or alkyl, or R 95 and R 96 , together with the nitrogen to which they are attached are linked to form a 4-8-membered heterocyclic ring comprising 1-3 heteroatoms; R 97 , R 98 and R 99 are hydrogen, alkyl, alkoxy or heteroaryl; and R 100 is hydrogen or alkyl, and or a cosmetically acceptable salt thereof.
