Abstract: Process for the continuous trichromatic dyeing of synthetic polyamide materials which comprises using at least one blue-dyeing fibre-reactive sulfo-containing anthraquinone dye together with at least one red-dyeing sulfo-containing azo dye and at least one yellow- or orange-dyeing sulfo-containing azo dye.The process according to the invention is suitable for the continuous dyeing of synthetic polyamide materials from aqueous liquors, producing level dyeings having good fastness properties, in particular good ozone fastness.

Abstract: A method for dyeing polyester fiber materials is disclosed, comprising conducting combination dyeing by a combination of disperse dyes each capable of making up for the color fading of other disperse dye produced upon exposure to sunlight, by the color change thereof in hue caused upon the exposure to sunlight under the same condition.
