    摘要: The present invention refers to dyestuffs of the formula (I) wherein A is carbon linked moieties especially chromophores; Y is N or C X1 is halogen or tertiary ammonium, especially pyridinium; L1 is a carbon based linking unit, optionally interrupted by O-atoms or optionally substituted N-atoms, especially ethylene or propylene R0, R1, R2 and R3 are independently hydrogen, C1 to C4 alkyl groups optionally substituted, or R2 is a group of the general formula (a*), or R3 independently is a group of the general formula (b*): (a*), (b*) wherein A1 and A2 have one of the meanings of A. Y1 and Y2 have independently one of the meanings of Y X2 and X3 have independently one of the meanings of X1, R4, R5, R6 and R7 are independently hydrogen or C1 to C4 alkyl optionally substituted. L2 and L3 are carbon based linking units, optionally interrupted by O-atoms or optionally substituted N-atoms, especially ethylene or propylene. R1 and R2 may be linked together such as to form a cyclic structure together with —N-L1-N+. If R2 is a group of formula (a*) or (b*) then R1 and R3 may be linked together such as to form a cyclic structure with —N-L1-N+, or R6 and R3 may be linked together such as to form a cyclic structure with —N+-L3-N—, or R4 and R3 may be linked together such as to form a cyclic structure with —N+-L2-N—, but not simultaneously, processes for the preparation of said dyesstuffs and their use for dyeing and printing hydroxy- and/or carboxamido-containing fiber materials.
