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.
Claims8
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.sub.1 is optionally-substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy and
- R.sub.2 and R.sub.3 are each independently hydrogen, optionally substituted lower alkyl, lower alkoxy, lower alkoxycarbonyl, halogen, nitrile or acyloxy.
