- the dyes of the formula I, Ha, Ilb, III, IV and V are generally known dyes. They are e.g. from DE-A-2 818 653, DE-A-3 112 427, EP-A-64 221, US-A 5 283 326 or from K. Venkataraman "The Chemistry of Synthetic Dyes', Vol. III, pages 444 to 447, Academic Press, New York, London, 1970, or can be obtained by the methods mentioned there.
- the dye mixtures according to the invention are prepared in a manner known per se, e.g. by mixing the respective partners in the weight ratio mentioned. If necessary, further components, e.g. Dispersants, such as lignin sulfonates or sulfonation products of the reaction product of formaldehyde with aromatics, or other auxiliaries, can be added. It is also possible to see already finished dye preparations from the respective partners or finished dye preparations with pure dyes.

- the material to be dyed is then removed, washed, optionally subjected to a reductive aftertreatment known per se (e.g. with sodium dithionite) at 60 to 80 ° C. and drying, and then treated with a silicone oil.
- a reductive aftertreatment known per se (e.g. with sodium dithionite) at 60 to 80 ° C. and drying, and then treated with a silicone oil.
- the material to be dyed is padded in an aqueous liquor at about 20 to 30 ° C with a commercially available silicone oil, e.g. based on amino-30 alkylm-modified polysiloxanes, with a liquor absorption of 50 to 100%. This is followed by drying at 100 to 130 ° C and finally fixing at 160 to 260 ° C.
- the dye mixtures according to the invention result in a strong coloration of 35 dyeings and have a neutral evening color. They also have excellent production properties.
- Aftertreatment of the polyesters dyed with the dye mixtures according to the invention in textile form with finishing agents based on silicone oils results in an increase in the color strength, which can be 20 to 40% depending on the quality of the polyester used.
- the textile goods treated in this way have the desired neutral evening color unchanged.
- the dyed polyester fabric is then reductively cleaned by placing it in 200 ml of a liquor containing 5 ml / l for 15 minutes
- polyester fabric is then padded with 40 g / l of a commercially available silicone oil based on an aminoalkyl-modified polysiloxane at a pH of 5 to 6.
- the liquor absorption is 100%. It is dried for 3 minutes at 120 ° C. and treated
- the dye preparation mentioned above each contained 40% by weight of dye mixture and 60% by weight of a dispersant based on lignin sulfonate, in each case based on the weight of the preparation.
- the dye mixture was composed as indicated in the following table, the following dyes being used.
