    • The present invention refers to dyestuffs of the formula (I) wherein A is carbon linked moieties especially chromophores; Y is N or C X 1 is halogen or tertiary ammonium, especially pyridinium; L 1 is a carbon based linking unit, optionally interrupted by 0-atoms or optionally substituted N-atoms, especially ethylene or propylene R 0 , R 1 , R 2 and R 3 are independently hydrogen, C 1 to C 4 alkyl groups optionally substituted, or R 2 is a group of the general formula (a*), or R 3 independently is a group of the general formula (b*): (a*), (b*) wherein A 1 and A 2 have one of the meanings of A. Y 1 and Y 2 have independently one of the meanings of Y X 2 and X 3 have independently one of the meanings of X 1 , R 4 , R 5 , R 6 and R 7 are independently hydrogen or C 1 to C 4 alkyl optionally substituted. L 2 and L 3 are carbon based linking units, optionally interrupted by O-atoms or optionally substituted N-atoms, especially ethylene or propylene. R 1 and R 2 may be linked together such as to form a cyclic structure together with -N-L 1 -N + . If R 2 is a group of formula (a*) or (b*) then R 1 and R 3 may be linked together such as to form a cyclic structure with -N-L 1 -N + , or R 6 and R 3 may be linked together such as to form a cyclic structure with -N + -L 3 -N-, or R 4 and R 3 may be linked together such as to form a cyclic structure with -N + -L 2 -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.
    • 本发明涉及式(I)的染料,其中A是碳连接的部分,特别是发色团; Y是N或C X 1是卤素或叔铵,特别是吡啶鎓; L 1是碳原子连接单元,任选地被0个原子或任选取代的N原子间隔,特别是乙烯或丙烯R 0,R 1,R 2和R 3独立地是氢 ,任选取代的C 1至C 4烷基,或R 2是通式(a *)的基团,或R 3独立地是通式(b *)的基团:(a *),( b *)其中A 1和A 2具有A.Y 1和Y 2的含义之一独立地是YX 2和X 3的含义之一独立地为 X 1,R 4,R 5,R 6和R 7的含义独立地为氢或任选取代的C 1至C 4烷基。 L 2和L 3是碳基连接单元,任选地被O原子或任选取代的N原子间隔,特别是乙烯或丙烯。 R 1和R 2可以连接在一起,以便与-N-L 1 -N +一起形成环状结构。 如果R 2是式(a *)或(b *)的基团,则R 1和R 3可以连接在一起,以形成具有-NL 1 -N +的环状结构 >或R 6和R 3可以连接在一起形成具有-N + -N 3 -N-的环状结构,或者R 4和R 3可以是 连接在一起,以形成具有-N + -L 2 -N-的环状结构,但不能同时制备所述染料的方法及其用于染色和印刷含羟基和/或甲酰胺基的 纤维材料
