ABSTRACT:
Dye mixtures of fiber-reactive azo dyes and their use for dyeing hydroxy- and/or carboxamido-containing fiber material
Red-dyeing fiber-reactive phenylazoaminonaphthol dyes, yellow-dyeing fiber-reactive phenylazoaminobenzene dyes, blue-dyeing fiber-reactive copper formazan dyes and navy-dyeing fiber-reactive disazo dyes of the formulae (1) to (5) as claimed and defined in claim 1 are described which are suitable for dyeing hydroxy- and/or carboxamido-containing fiber material, such as cellulose fiber materials, wool and synthetic polyamide fibers individually or together or some of them together or as a mixture in trichromatic dyeing methods. During the dyeing process a definite hue within the color triangle can be obtained and kept constant by adding the individual dye solutions of the individual dyes and/or mixtures of some of the dyes in a controlled manner by means of the ATR measurement technique.
