Process for the preparation of fast dyeings or prints on synthetic fibrous materials

Abstract

Abstract IN WHICH A represents a linear branched alkylene group of 1 to 4 carbon atoms being unsubstituted or substituted by hydroxyl, methoxy, ethoxy, or phenoxy, B represents phenyl being unsubstituted or substituted by fluorine, chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, trifluoromethyl, cyano, carbo(lower)alkoxy, nitro, acetyl, benzoyl or phenyl or by combinations of two members thereof, or naphthyl, X represents -NH- or a direct linkage, and R represents hydrogen, acetyl, propionyl or benzoyl, the yellow dyeings or prints so obtained being distinguished by excellent fastness properties, particularly by a very good fastness to light, a high resistance to sublimation and furthermore, by very good colour yields. A process for the preparation of fast dyeings or prints on synthetic fibrous materials, which comprises treating the said fibrous materials in an aqueous dispersion or in an organic solvent with a dyestuff of the formula (1)
