Dyes of the formula ##STR1## WHEREIN F is a dye of the disperse class, n is 1 or 2, and W is the radical of a diammonium or aminoammonium compound which is linked through an ammonium group to the methylenecarbonyloxy radical, said dyes finding utility in dyeing and printing hydrophobic synthetic organic materials, especially polyester materials in an aqueous dyebath at elevated temperatures, whereby the carbacyl group undergoes hydrolysis to form a disperse dye which exhausts onto the material.
WHEREIN R1'' and R2'' are each hydrogen, C1-C4-alkyl optionally interrupted by an oxygen atom and optionally substituted by phenyl, cyano, chlorine, bromine, fluorine, C1-C4-alkoxy, formylamino, formyloxy, C1-C5-alkylcarbonylamino, C1-C5alkylcarbonyloxy, benzoyloxy, benzoylamino, C1-C4alkylcarbamyloxy, phenylcarbamyl, C1-C4-alkyloxycarbonyloxy, phenoxycarbonyloxy, and phenoxy.

摘要:
The invention comprises dyestuffs of the formula where F is an organic dyestuff radical, R is alkylene or cycloalkylene, R2 is alkylene, R1 is -S-or where X is hydrogen, an araliphatic or cycloaliphatic substituent or an aliphatic radical which may form part of a heterocyclic nitrogen-containing 5 or 6 membered ring, Y is a substituent which, upon treatment with alkaline substances and/or heat, may be split off as a negative ion leaving R2 with a positive charge, and n is a whole number. Organic dyestuffs specified are those of the azo, anthraquinone, triphenylmethane, oxazine or azaporphin series, and values specified for Y are the sulphuric acid ester, phosphoric acid ester and sulphonyloxy groups and halogen atoms. The dyestuffs are made by reacting a dyestuff sulphonic acid chloride or carboxylic acid chloride with an amine containing the group -R-R1-R2-Y, by esterifying dyestuffs of the above general formula but wherein the group Y is hydroxyl, or by synthesising the dyestuffs from dyestuff intermediates already containing the group -R-R1-R2-Y, for example by diazotisation and coupling in the case of azo dyestuffs. The dyestuffs dye and print textile materials of natural or regenerated cellulose in conjunction with an alkali and heat treatment, and wool and silk from a weakly alkaline or neutral medium to give a variety of shades. Reference has been directed by the Comptroller to Specifications 835,819 and 868,741.
