Abstract
PURPOSE: To carry out orange or scarlet dyeing or printing of a cellulosic fiber, with excellent color fastness to chlorine, light, and combination of perspiration and sunlight, by using a reactive monoazo dye containing a β-sulfatoethylsulfone group and represented by specific structural formula.
CONSTITUTION: Cellulosic fiber is dyed with a dye having β-sulfatoethylsulfone group and monochlorotriazinyl group as reactive groups and represented, as a free acid, by formula I (R1 is methyl or ethyl; R2 is lower alkyl or lower alkoxy; X1 and X2 are H, chlorine, methyl, carboxylic acid, sulfonic acid, etc.). The dye of formula I can be prepared, e.g. by (1) diazotizing an anilinesulfonic acid compound of formula II, (2) coupling the product with J acid of formula III, (3) condensing the coupling product with cyanuric chloride to afford dichlorotriazinyl compound, and (4) condensing the product with an aniline compound of formula IV.
EFFECT: The dye gives high density dyed product, and has excellent wash-off characteristics.
