Patent ID: 7414129

Claim:
A triphendioxazine dye of the formula I where A 1 and A 2 are independently hydrogen, phenyl, (C 1 -C 6 )-alkyl or substituted (C 1 -C 6 )-alkyl; B is phenylene, substituted phenylene, naphthylene or substituted naphthylene; R 1 is hydrogen, (C 1 -C 6 )-alkyl or phenyl; Y 1 is a group of the general formula II or III where X 1 to X 3 are independently hydrogen, cyano or halogen with the proviso that at least one of X 2 and X 3 is halogen; X 4 is chlorine or fluorine; and R 2 and R 3 are independently hydrogen, (C 1 -C 6 )-alkyl, (C 3 -C 8 )-cycloalkyl, (C 1 -C 6 )-alkyl with hydroxyl, —SO 3 M, —SO 2 Z, —OSO 3 M, —COOM, cyano, (C 1 -C 6 )-alkoxy, ZSO 2 -(C 1 -C 6 )-alkoxy or phenyl substitution, phenyl, phenyl substituted by one, two or three substituents selected from (C 1 -C 6 )-alkyl, (C 1 -C 6 )-alkoxy, (C 1 -C 6 )-alkoxy-(C 1 -C 6 )-alkoxy, hydroxy-(C 1 -C 6 )-alkoxy, halogen, —SO 3 M, —CH 2 SO 3 M, —SO 2 Z, —SO 2 NR 4 R 5 , —CON(R 6 )—(CH 2 ) 2-3 —SO 2 Z or —NHCOX 5 , or R 2 and R 3 combine with the interadjacent nitrogen atom to form a five- or six-membered saturated ring which contains one or two groups —O— or —NR 7 —, where R 7 is hydrogen or (C 1 -C 6 )-alkyl, where M is hydrogen, ammonium, an alkali metal or the equivalent of an alkaline earth metal; R 4 and R 5 are independently hydrogen, (C 1 -C 6 )-alkyl or hydroxy-(C 1 -C 6 )-alkyl; R 6 is hydrogen, (C 1 -C 6 )-alkyl or phenyl; Z is —CH═CH 2 or —CH 2 CH 2 Y 2 , where Y 2 is an alkali-eliminable grouping; and X 5 is —CH(Hal)—CH 2 —Hal or —CH(Hal)═CH 2 , where Hal is chlorine or bromine.
