摘要
Dyeing formulations in solid or liquid form, containing one or more red disperse dyes of the general formula (1) IMAGE (1) where R1 denotes an alkyl group of 1 to 4 carbon atoms, and one or more red disperse dyes of the general formula (2) IMAGE (2) where R2 and R3 denote independently of each other the group -CH2-CH2-CH2-COOCH3 or -CH2-CH2-CH2-COOC2H5 and R4 denotes a hydrogen, chlorine or bromine atom or a methyl group, one or more anion-active or nonionic dispersing agents and optionally water, wherein, based on the mixing ratio of the pure dyes to one another, the dyes of the formula (1) are present in a proportion of 15 to 85 percent by weight and the dyes of the formula (2) in a proportion of 85 to 15 percent by weight, and wherein the dyes have been brought into a state of extremely fine division by conjoint or separate wet grinding in the presence of a dispersing agent, and the use thereof for dyeing or printing polyester fibers or mixtures of polyester and cellulose fibers.
