New mono- and bis-rylenedicarbimidyl-anthraquinone dyes (I) are claimed. New mono- and bis-rylenedicarbimidyl-anthraquinone dyes are of formula (I). R = H or (substituted) 1-30 C alkyl, 5-8 C cycloalkyl or (het)aryl; R' = Br, CN, -NR32 or (substituted) (het)aryloxy, (het)arylthio or 3-18 C alk-1-ynyl; R3 = H, 1-18 C alkyl or (substituted) (het)aryl; or NR32 = a 5-7-membered heterocyclic group; X, Y = H or together a 6-membered ring attached to a rylene ring system (Ia), in which X corresponds to the -NH- group and Y to the other free bond; n = 2, 3, 4 or may also be 1 if X and Y are a (Ia) group; and m = 0-6. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for methods of preparing asymmetric (I; where X, Y = H) and symmetric and asymmetric (I, where X, Y = a 6-membered ring attached to arylene ring system). |
