Abstract:
SAID DYESTUFFS BEING HIGHLY SUITABLE FOR THE DYEING OF FIBROUS MATERIALS CONSISTING OF CELLULOSE-2 1/2 -ACETATE, CELLULOSETRIACETATE, POLYAMIDE, POLYURETHANE OR, PARTICULARLY, OF POLYESTERS, SUCH AS POLYETHYLENEGLYCOLTEREPHTHALATES.
Abstract:
A process for the preparation of fast dyeings or prints on synthetic fibrous materials, which comprises treating the said fibrous materials in aqueous dispersion or in an organic solvent with a dyestuff of the formula (1)
IN WHICH A represents a linear or branched alkylene group of 1 to 4 carbon atoms being unsubstituted or substituted by methoxy, ethoxy, phenoxy or hydroxyl, and B represents phenyl being unsubstituted or substituted by fluorine, chlorine, bromine, cyano, trifluoromethyl, acetyl, benzoyl, phenyl, phenoxy, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms or by combinations of 2 or 3 members thereof, or naphthyl 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.
Abstract:
A process for the preparation of fast dyeings or prints on synthetic fibrous materials which comprises treating the said fibrous materials in aqueous dispersion or in an organic solvent with dyestuffs of the formula IN WHICH R1 represents alkyl from one to four carbon atoms being unsubstituted or substituted by methoxy or ethoxy, and R2 represents phenyl being unsubstituted or substituted by fluorine, chlorine, bromine, alkyl or one to four carbon atoms, alkoxy of one to four carbon atoms, trifluoro-methyl, nitro, hydroxy, cyano, carbo(lower)alkoxy, acetyl, benzoyl, phenyl or phenoxy, the yellow dyeings or prints so obtained being distinguished by excellent fastness properties, particularly by a very good fastness to light and a high fastness to sublimation.
