- 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.

- Fiber-reactive disazo brown dye having vinylsulfone-type reactive group
-
A compound, or a salt thereof, represented by the following formula, STR1 wherein A is a substituted or unsubstituted phenylene or naphthylene group, B is STR2 in which R3 is a hydrogen atom or a lower alkyl, lower alkoxy, acylamino or ureido group, and R4 is a hydrogen atom or a lower alkyl or lower alkoxy group, R1 and R3 are independently a hydrogen atom or a substituted or unsubstituted lower alkyl group, X is a substituted or unsubstituted amino, lower alkoxy, substituted phenoxy or sulfo group, Y is --SO2 CH=CH2 or --SO2 CH2 CH2 Z, in which Z is a group capable of being split by the action of an alkali, and m is 2 or 3, which is useful for dyeing hydroxyl group- or amide group-containing fiber materials to give dyed products of a brown color having excellent fastness properties with good build-up property.

- Reactive yellow dye having both monochlorotriazinyl and vinylsulfone type reactive groups
-
The compounds represented, in the form of free acid, by the following general formula (I): STR1 (wherein A is STR2 (wherein R3 and R4 are each hydrogen or a methyl, ethyl, methoxy, ethoxy, acetylamino, propionylamino, benzoylamino or ureido group, and R5 and R6 are each hydrogen or a methyl or methoxy group), R1 and R2 are each hydrogen or a methyl, ethyl or sulfomethyl group, X1 and X2 are each hydrogen, chlorine or a methyl, methoxy, carboxyl or sulfonic acid group, m is a number of 0, 1 or 2, and n is a number of 1 or 2, provided that the sum of m and n is 1, 2 or 3). These compounds are capable of dyeing cellulose fibers in yellow with excellent color fastness to hypochlorite, light, perspiration and sunlight and high acid stability.
