Definitions

  • the proportion of the quinophthalones (II) in the mixtures is preferably 10 to 90% by weight, in particular 20 to 50% by weight.
  • the dyeing of polyester in the alkaline range has proven to be advantageous, since oligomers of the polyester which normally settle on parts of the dyeing apparatus are saponified, so that frequent cleaning of the dyeing apparatus is avoided.
  • these dyes have only moderate lightfastness.
  • the dyeings with the mixtures according to the invention also have a significantly lower "catalytic fading", in particular when they are used in a mixture with blue disperse dyes, compared to the dyeings which are obtained with the azo dyes alone.
  • Individual dyes or mixtures are preferably added to the dye mixture to be ground one or more dispersants.
  • the particle size of the dye particles can be influenced accordingly by a milling treatment, for example wet bead milling, and adjusted to a desired value.
  • the anionic dispersants are preferred, and a mixture of anionic and nonionic dispersants is particularly preferred.
  • Suitable ethylene oxide adducts are in particular the alkylatable compounds mentioned under a) to e) with 5 to 30 moles of ethylene oxide.
  • the spray drying of a slurry containing the dye mixtures according to the invention is preferably carried out in conventional spray dryers at dryer inlet temperatures of 130 to 160 ° C., preferably from 140 to 150 ° C. and outlet temperatures of 50 to 80 ° C., preferably from 60 to 70 ° C.
  • the required amounts of the dye settings which have been prepared in accordance with the above information are diluted with the dyeing medium, preferably with water, to such an extent that a liquor ratio of 1: 5 to 1:50 results for the dyeing.
  • further dyeing aids such as dispersing, wetting and fixing aids, are generally added to the liquors.
