Abstract
Abstract Water-soluble fiber-reactive yellow dyestuffs of the formula wherein M is hydrogen or an alkali metal, such as sodium, potassium or lithium, or the equivalent of an alkaline earth metal, such as of calcium, and X is the vinyl group or a group of the formula (2) in which Z is hydroxy, chlorine, bromine, sulfato, thiosulfato, phosphato, acetyloxy, propionyloxy or di-(lower alkyl)-amino. Process for their preparation. Liquid compositions of said dyestuffs are also disclosed. Use of these dyestuffs in coloring a material made of cellulose, wool. silk and/or polyamide fibers.

Independent Claim
54 words
A water-soluble fiber-reactive dyestuff of the general formula (1) wherein M is hydrogen or an alkali metal, or the equivalent of an alkaline earth metal, and X is the vinyl group or a group of the general formula (2) in which Z is hydroxy, chlorine, bromine, sulfato, thiosulfato, phosphato, acetyloxy, propionyloxy or di-(lower alkyl)-amino.
Claim 2
Dependent Claim
54 words
A water-soluble fiber-reactive dyestuff of the general formula (1) wherein M is hydrogen or an alkali metal, or the equivalent of an alkaline earth metal, and X is the vinyl group or a group of the general formula (2) in which Z is hydroxy, chlorine, bromine, sulfato, thiosulfato, phosphato, acetyloxy, propionyloxy or di-(lower alkyl)-amino.
Claim 3
Dependent Claim
18 words
A dyestuff according to claim 1 of the formula in which M is defined as in claim 1.
Claim 4
Dependent Claim
18 words
A dyestuff according to claim 1 of the formula in which M is defined as in claim 1.
Claim 5
Dependent Claim
56 words
A process for the preparation of a dyestuff of the general formula (1) mentioned and defined in claim 1, which comprises coupling a compound of the formula (3) in which M is defined as in claim 1, with a diazotized amino compound of the general formula (4) in which X is defined as in claim 1.
Claim 6
Dependent Claim
19 words
A liquid dyestuff composition comprising 5 to 45 % of a water-soluble dyestuff according to claim 1, and water.

Dependent Claim
19 words
A liquid dyestuff composition comprising 5 to 45 % of a water-soluble dyestuff according to claim 2, and water.
Claim 8
Dependent Claim
21 words
A liquid dyestuff composition according to claim 5 or 6, which additionally comprises from 0 to 6 % inert inorganic salt.
Claim 9
Dependent Claim
30 words
A liquid dyestuff composition according to claim 5, 6 or 7, wherein said inert inorganic salt is selected from the alkali metal and ammonium chlorides and sulfates and mixtures thereof.
Claim 10
Dependent Claim
23 words
A liquid dyestuff composition according to claim 5, 6, 7 or 8, which comprises from 10 to 20 % of said water-soluble dyestuff.
Claim 11
Dependent Claim
26 words
