Abstract
Abstract A process for the coloration of aromatic polyester textile materials which comprises applying to the said textile materials by an aqueous dyeing, padding or printing process a disperse monoazo dyestuff, free from carboxylic acid and sulphonic acid groups, which, in one of the possible tautomeric forms, is represented by the formula: <IMAGE> wherein A is phenyl or phenyl which contains at least one substituent selected from chlorine, bromine, nitro, cyano, trifluoromethyl, thiocyano, lower alkyl, lower alkoxy, lower alkylcarbonyl, lower alkylsulphonyl, lower alkylcarbonylamino, carbamoyl and N-lower alkyl and N:N-di lower alkyl derivatives thereof, sulphamoyl and N-lower alkyl and N:N-di lower alkyl derivatives thereof, sulphamato and N-lower alkyl and N:N-di lower alkyl derivatives thereof, lower alkoxycarbonyl, lower alkoxy lower alkoxycarbonyl, lower alkoxy lower alkoxy lower alkoxycarbonyl, hydroxy lower alkoxycarbonyl, hydroxy lower alkoxy lower alkoxycarbonyl, and lower alkoxycarbonyl lower alkyl.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A process for the colouration of aromatic polyester/cellulose or aromatic polyester/polyamide union textile materials which comprises applying to the said textile materials, by an aqueous dyeing, padding or printing process, (1) a disperse monoazo dyestuff, free from carboxylic acid and sulphonic acid groups, which, in one of the possible tautomeric forms, is represented by the formula: ##STR9## wherein n is 0 or 1, Y is lower alkyl, lower alkoxy lower alkyl, lower alkoxy lower alkoxy lower alkyl, hydroxy layer alkyl or hydroxy lower alkoxy lower alkyl, and the remaining positions of the benzene ring A 1 are bonded to hydrogen chlorine, bromine, nitro, lower alkoxycarbonyl, lower alkyl or lower alkoxy, X is hydrogen, lower alkyl, carbamoyl, cyano, chlorine, bromine, nitroso, nitro, lower alkylcarbonyl, sulphamoyl, lower alkylsulphonyl, lower alkylcarbonylamino or lower alkoxycarbonyl; and Z is hydrogen or lower alkyl; and (2) a dyestuff to colour the cellulose or polyamide fibers, and subsequently giving the coloured textilel material a treatment in an aqueous alkaline bath which does not contain a reducing agent, at a pH above 8 and at a temperature between 50° and 85° C.
Claim 2
Dependent Claim
184 words
A process for the colouration of aromatic polyester/cellulose or aromatic polyester/polyamide union textile materials which comprises applying to the said textile materials, by an aqueous dyeing, padding or printing process, (1) a disperse monoazo dyestuff, free from carboxylic acid and sulphonic acid groups, which, in one of the possible tautomeric forms, is represented by the formula: ##STR9## wherein n is 0 or 1, Y is lower alkyl, lower alkoxy lower alkyl, lower alkoxy lower alkoxy lower alkyl, hydroxy layer alkyl or hydroxy lower alkoxy lower alkyl, and the remaining positions of the benzene ring A 1 are bonded to hydrogen chlorine, bromine, nitro, lower alkoxycarbonyl, lower alkyl or lower alkoxy, X is hydrogen, lower alkyl, carbamoyl, cyano, chlorine, bromine, nitroso, nitro, lower alkylcarbonyl, sulphamoyl, lower alkylsulphonyl, lower alkylcarbonylamino or lower alkoxycarbonyl; and Z is hydrogen or lower alkyl; and (2) a dyestuff to colour the cellulose or polyamide fibers, and subsequently giving the coloured textilel material a treatment in an aqueous alkaline bath which does not contain a reducing agent, at a pH above 8 and at a temperature between 50° and 85° C.
Claim 3
Dependent Claim
36 words
A process as claimed in claim 1 wherein the aqueous alkaline bath having a pH above 8 additionally contains from 0.2 to 1.0% by weight, based on the weight of the bath, of a synthetic detergent.
Claim 4
Dependent Claim
33 words
Process as claimed in claim 1 wherein the said disperse monoazo dyestuff is applied in conjunction with a disperse dyestuff of the aminoazobenzene series which contains at least two carboxylic acid ester groups.
Claim 5
Dependent Claim
30 words
Process as claimed in claim 1 wherein the textile material is an aromatic polyester/cellulose union, and a Reactive Dyestuff is used to colour the cellulose fibres present in the union.
Claim 6
Dependent Claim
17 words
Process as claimed in claim 4 wherein the disperse dyestuff, and the Reactive Dyestuff are applied together.
Claim 7
Dependent Claim
26 words
Process as claimed in claim 4 herein the colouration of the textile material is carried out in a continuous manner by a printing or padding process.
Claim 8
Dependent Claim
36 words
Process as claimed in claim 1 wherein the Reactive Dyestuff contains a 1:3:5-triazin-2-ylamino group having a chlorine atom attached to one or both of the carbon atoms in the 4- and 6-positions of the triazine ring.
Claim 9
Dependent Claim
18 words
Process as claimed in claim 1 wherein Y is lower alkyl, n is 0, and X is --CN.
Claim 10
Dependent Claim
14 words
Aromatic polyester textile materials whenever coloured by a process as claimed in claim 1.
