Reactive yellow dye for ink jet printing and preparation method and application thereof

The invention relates to a reactive yellow dye for ink jet printing and a preparation method and application thereof, belonging to the field of fine chemical industry. The reactive yellow dye shown inthe formula(I)has higher solubility, good fixation rate and color fastness, high stability after dyeing and bright color light, can be widely applied to dip dyeing, pad dyeing and ink jet printing ofcotton, hemp and artificial cotton fiber fabrics, has low production cost, and can be popularized and applied on a large scale.

Triazinyl reactive dyes containing additional fiber reactive groups bound through the sulfonylalkylaminoalkylamino bridge

The invention relates to novel useful reactive dyes of the formula I STR1 in which: F is a radical selected from the group consisting of metal-free or metal-containing monoazo or disazo dyes containing at least one --SO3 H group, anthraquinone dyes, sulfophthalocyanine dyes, formazan dyes, phenazine dyes, oxanine dyes and nitroaryl dyes, R is hydrogen, C1 -C4 alkyl which is unsubstituted or substituted with --COOH or --SO3 H, cyanoethyl, or hydroxyethyl, X is fluorine, chlorine, bromine, --SO3 H, phenylsulfonyl or C1 -C4 -alkylsulfonyl, P is 1 or 2 and A is a radical of the formula STR2 in which: the groups designated "alk" are independently of each other straight or branched polymethylene radicals having 2 to 6 carbon atoms, and Z is β-halogenoethyl, vinyl, β-sulfatoethyl, β-thiosulfatoethyl or βacetoxyethyl.

Bisazo brown reactive dye

A brown reactive dye represented by a free acid of the formula, STR1 wherein R is a hydrogen atom or a C1 to C4 alkyl group, X is --SO2 CH2 CH2 Cl, --SO2 CH=CH2, --SO2 CH2 CH2 OSO3 H or --SO2 CH2 CH2 OPO3 H2, rings A, B and C are each a benzene or naphthalene ring which may have other substituent, m is 0 to 3 and n is 0 to 1. This dye is suitable for dyeing cellulose fibers brown to afford dyeings superior in fastnesses, acid stability, build-up property and level dyeing property.
