Abstract
Abstract A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-amino-4-anilinoanthraquinone having one or two ortho substituents in the anilino group. The anthraquinone nucleus may be further substituted in the 2- and/or 3-position, preferably by an electron-withdrawing group in the 2-position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A process for the transfer color printing of synthetic textile materials which comprises placing a transfer material which carries a colored pattern, derived from one or more disperse anthraquinone dyestuffs, in contact with a synthetic textile material and heating the transfer material and the synthetic textile material whilst in contact so as to transfer the dyestuff from the transfer material to the synthetic textile material, the disperse anthraquinone dyestuff or dyestuffs being of the formula: ##STR4## wherein X and Y are each independently hydrogen, optionally substituted lower alkyl, lower alkoxy, lower alkylmercapto or an electron-withdrawing group; R 1 is optionally-substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy and R 2 and R 3 are each independently hydrogen, optionally substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy.
Claim 2
Dependent Claim
132 words
A process for the transfer color printing of synthetic textile materials which comprises placing a transfer material which carries a colored pattern, derived from one or more disperse anthraquinone dyestuffs, in contact with a synthetic textile material and heating the transfer material and the synthetic textile material whilst in contact so as to transfer the dyestuff from the transfer material to the synthetic textile material, the disperse anthraquinone dyestuff or dyestuffs being of the formula: ##STR4## wherein X and Y are each independently hydrogen, optionally substituted lower alkyl, lower alkoxy, lower alkylmercapto or an electron-withdrawing group; R 1 is optionally-substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy and R 2 and R 3 are each independently hydrogen, optionally substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy.
Claim 3
Dependent Claim
20 words
A process as claimed in claim 1 wherein at least one of X and Y is an electron withdrawing group.
Claim 4
Dependent Claim
13 words
A process as claimed in claim 2 wherein X is an electron-withdrawing group.
Claim 5
Dependent Claim
19 words
A process as claimed in claim 1 wherein the heating is carried out at a temperature from 160°-220° C.
Claim 6
Dependent Claim
38 words
A process as claimed in claim 1 wherein the heating of the transfer material and the synthetic textile material whilst they are in contact is effected in a zone the pressure of which is less than atmospheric pressure.
Claim 7
Dependent Claim
20 words
A process as claimed in claim 5 wherein the pressure in the zone is less than 100 mm of mercury.
Claim 8
Dependent Claim
18 words
A process as claimed in claim 1 wherein the synthetic textile material is an aromatic polyester textile material.
Claim 9
Dependent Claim
14 words
A synthetic textile material whenever colored by a process as claimed in claim 1.
