摘要:
Navy and black dye mixtures contain one or more thiophene-azo dyes of the formula ##STR1## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, X and Y each have defined meanings, and one or more dyes F whose absorption maximum is at a wavelength of from 390 to 520 nm, the proportion of thiophene-azo dyes being from 60 to 99% by weight, based on the total weight of thiophene-azo dyes and dyes F in the mixture.
