PROCESS FOR THE PREPARATION OF A WATER-SOLUBLE COMPOUND, ITS APPLICATION, PROCESS FOR DYEING (INCLUDING STAMPING) OF MATERIAL CONTAINING HYDROXY GROUPS AND / OR CARBONAMID GROUPS, AND PROCESS FOR DYEING FIBER MATERIAL CONTAINING HYDROXI GROUPS

摘要

Water-soluble compounds having fiber-reactive dye properties of the general formula IMAGE in which A is an alkylene of 2 to 6 carbon atoms or a phenylene which can be substituted by 1 or 2 substituents, or is a radical of the formula IMAGE in which W is a direct bond or a bridge member and the R' and R* each denote hydrogen, chlorine, methyl, methoxy, ethoxy, carboxy or sulfo; B is chlorine or fluorine; R is hydrogen, chlorine, an alkyl of 1 to 4 carbon atoms or an alkoxy of 1 to 4 carbon atoms; M is hydrogen or an alkali metal; n stands for the number zero, 1 or 2, K is a radical of the formula IMAGE IMAGE IMAGE +TR IMAGE in which D is phenylene which can be substituted by chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxy or sulfo, or is naphthalene with optionally 1 or 2 sulfo groups, R1 denotes hydrogen, chlorine, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms, R2 is hydrogen or alkyl of 1 to 4 carbon atoms, G is carboxy, methyl or carbalkoxy of 2 to 5 carbon atoms, Y denotes vinyl, beta -sulfatoethyl, beta -phosphatoethyl, beta -thiosulfatoethyl or beta -chloroethyl, Z is the alpha - or beta -bromoacryloyl or beta -chloropropionyl or a radical of the formula IMAGE with B, D and Y of the abovementioned meanings. The novel dyes are suitable for dyeing hydroxyl- and/or carbamoyl-containing material; on hydroxyl-containing material, such as cellulose fibers, they become fixed not only in the alkaline but also in the weakly acid to neutral range, so that they can be used together with disperse dyes for dyeing blend material composed of cellullose and polyester fibers by the dyeing methods for disperse dyes.
