摘要:
A dyestuff of the formula (I) wherein D is a diazo component; R1 is hydrogen, (C1-C4)-alkyl, hydroxy, —NHCOR6 or —NHSO2R6; R2 is hydrogen, halogen or (C1-C4)-alkoxy; R3 is hydrogen or methyl; R4 is hydrogen, (C1-C6)-alkyl, substituted (C1-C6)-alkyl, (C2-C6)-alkyl, which is interrupted by 1, 2 or 3 heteroatoms wherein said heteroatoms are —0—, —S— or —NR7, substituted (C2-C6)-alkyl, which is interrupted by 1, 2 or 3 heteroatoms wherein said heteroatoms are —0—, —S— or —NR7, (C2-C6)-alkenyl, substituted (C2-C6)-alkenyl, benzyl or phenethyl; R5 is hydrogen or methyl; R6 is (C1-C4)-alkyl, phenyl or substituted phenyl; R7 is (C1-C4)-alkyl, phenyl or substituted phenyl; m is 0, 1 or 2; and n is 0 or 1. The invention further relates to use of the dyestuff and the process of making the dyestuff.
摘要:
A disperse dye of formula I wherein R1 and R2 independently are each (C1-C4)-alkyl,OH or (C1-C4)-alkoxy-substituted (C1-C4)-alkyl; R3 and R4 independently are each hydrogen or methyl; one of A and B is cyano and the other is —COOX; and X is (C2-C12)-alkyl, O-interrupted (C2-C12)-alkyl, (C3-C4)-alkenyl or phenyl-(C1-C4)-alkyl. The invention also relates to the preparation of the dye and the use of the dye.
摘要:

摘要:
The present invention relates to methods and compositions for removing excess dye from dyed and/or printed materials, such as, textile materials dyed with disperse dyes, by treating a dyed or printed material with an esterase. The improvements resulting form the present invention include, for example, improvements in the washfastness, the wetfastness, the crockfastness, sublimation, and/or the quality of the color, such as, brightness, of dyed and/or printed materials. The present invention also relates to methods for printing or dyeing a material by dyeing or printing the material with a combination of a dye that is affected by esterase treatment and a dye that is not affected by esterase treatment, and after dyeing or printing the material, discharging residual dye by treating the material with an esterase.
摘要:
In the dyeing of hydrophobic fibers comprising new synthetic fibers, especially those called micronfine fibers, etc., it is difficult to obtain a dyed product having excellent fastness and it is further difficult to obtained a dyed product excellent also in color rendering. The present invention solved the problem as following:A specific dye composition containing a water-insoluble monoazo disperse dye represented by a specific structural formula is used to dye hydrophobic fibers, especially polyester fibers, comprising micronfine fibers, thereby giving a dyed products excellent in fastness balance and color rendering.
摘要:
Dye mixtures comprising:A) a dye of the formula ##STR1## in which R.sub.1 is C.sub.1 -C.sub.4 alkyl,R.sub.2 is the radical (CH.sub.2).sub.n O--R.sub.5,R.sub.5, independently of R.sub.1, is C.sub.1 -C.sub.4 alkyl andn is the number 1, 2 or 3 andB) a dye of the formula ##STR2## in which R.sub.3 and R.sub.4 independently of one another are C.sub.1 -C.sub.4 alkyl, which are suitable for dyeing or printing textile fiber materials and give dyeings with good allround properties, are described.
