Dyeing of polyamide substrates with an organic N-nitroso-hydroxylamine

Navy and black dye mixtures contain one or more thiopheneazo dyes whose diazo component comes from the 2-aminothiophene series and whose coupling component comes from the aniline series and one or more dyes F whose absorption maximum is at a wavelength of from 390 to 520 nm, the proportion of the thiopheneazo dyes being from 60 to 99% by weight, based on the total weight of the thiopheneazo dyes and the dyes F in the mixture.

Benzophenone ether esters and use thereof to improve the light fastness

A process for improving the lightfastness of dyeings obtained with acid dyes and/or metal complex dyes on polyamide textile materials, by treating the latter with 0.01-1% by weight of a copper hydroxamate before, during or after dyeing.

Lightfastness of dyeings obtained with acid dyes or metal complex dyes

Dyes of the formula ##STR1## where A and B are H and/or ##STR2## Y is unsubstituted or substituted phenyl, ##STR3## or unsubstituted or substituted benzothiazolyl or benzoxazolyl and R is unsubstituted or substituted alkyl, unsubstituted or substituted phenyl, or alkoxy, alkoxyalkoxy, phenalkyl or alkoxycarboalkyl, are suitable for dyeing and printing cellulose swollen with water-miscible swelling agents and cellulose-containing fiber material.

Anthraquinoid dyes

A process for improving the lightfastness of dyeings obtained with acid dyes and/or metal complex dyes on polyamide textile materials, by treating the latter and 0.01-1% by weight of a copper hydroxamate before, during or after dyeing.
