- Fiber reactive anthraquinone dyes
-
Fiber reactive dyes of the anthraquinone type which provide brilliant violet colors without metal complexing. These dyes may be represented by the formula: STR1 wherein W is selected from NR2 and oxygen; R is independently selected from hydrogen, C1 -C6 alkyl; C1 -C6 alkoxy, sulfo and carboxy; R1 is selected from hydrogen, C1 -C6 alkyl and phenyl; R2 is selected from hydrogen and C1 -C6 alkyl; R3 is selected from hydrogen, and C1 -C4 alkyl; n is an integer of 1 or 2; and Y is CH=CH2, or CH2 CH2 Z wherein Z is a group capable of being split off by the action of an alkali reagent.
