Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
59 words
A method for the coloration of cotton or polyester/cotton blend textile materials which comprises applying thereto by a printing or continuous dyeing technique a colored polymer containing repeat units derived from at least one organic dye which is free from water-solubilizing groups and contains two or more polymerizable olefinically unsaturated groups and from at least one uncolored polymerizable olefin.
Claim 2
Independent Claim
59 words
A method for the coloration of cotton or polyester/cotton blend textile materials which comprises applying thereto by a printing or continuous dyeing technique a colored polymer containing repeat units derived from at least one organic dye which is free from water-solubilizing groups and contains two or more polymerizable olefinically unsaturated groups and from at least one uncolored polymerizable olefin.
Claim 3
Dependent Claim
93 words
A method according to claim 1 wherein the polymerisable olefinically unsaturated groups in the organic dye have the formula: ##STR20## wherein X represents an atom or group linking the olefinic group to a carbon atom present in the dye molecule, n has the value 0 or 1 and each of R 1 , R 2 and R 3 independently represents a hydrogen or halogen atom or a hydroxyl, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted alkylthio, cycloalkyl, optionally substituted aryl, optionally substituted aryloxy, optionally substituted arylthio, nitro, cyano, acyloxy or alkoxycarbonyl group.
Claim 4
Dependent Claim
27 words
A method according to claim 2 wherein each of R 2 and R 3 is hydrogen and R 1 is hydrogen, halogen, lower alkyl, cyano or alkoxycarbonyl.
Claim 5
Dependent Claim
11 words
A method according to claim 3 wherein R 1 is methyl.
Claim 6
Dependent Claim
23 words
A method according to claim 2 wherein the polymerisable groups have the formula: --O--CO--CR.sup.5 ═CH.sub.2 wherein R 5 is hydrogen or lower alkyl.
Claim 7
Dependent Claim
11 words
A method according to claim 5 wherein R 5 is methyl.
Claim 8
Dependent Claim
15 words
A method according to claim 1 wherein the dye contains two polymerisable olefinically unsaturated groups.
Claim 9
Dependent Claim
75 words
A method according to claim 2 wherein the organic dye is an azo dye having the formula: ##STR21## wherein A represents the residue of a carbocyclic or heterocyclic diazotisable amine containing at least one electron-withdrawing substituent, E represents the residue of a carbocyclic or heterocyclic coupling component, m is an integer of at least 2, and R 1 , R 2 , R 3 , X and n have the meanings given in claim 2.
Claim 10
Dependent Claim
24 words
A method according to claim 1 wherein the coloured copolymer contains from 2 to 10% by weight of units derived from an organic dye.
Claim 11
Dependent Claim
14 words
A method according to claim 1 wherein the uncoloured polymerisable olefin is methyl methacrylate.
