The proposed azo dyes have good color nokazatel MP and also high selectivity.

The proposed azo dyes have a significantly better JnocTb dye stain compared to analogous dyes and are suitable for dyeing the most diverse materials, for example silk, wool, superpolyamide fibers, plastic fibers, ianrpmer, from regenerated cellulose or rayon fibers, and also natural patterns. or most likely a hlonka. These dyes, already in weakly acidic and also in acidic medium, have a high affinity for the proteins above, containing nitrogen, materials, and especially for cellulose.

Painted materials are characterized by good tolerance to stannion and resistance to the shaft.

New dyes containing sulfogruiii with respect to fibers and also dyes for cellulose dyeing and the so-called plus-dye dyeing method, in which the material is impregnated with water and, in accordance with PC1, it contains salt solution of dyes and phyla; in a warm environment. As a result of this method, dashes are obtained, distinguished primarily by superior water resistance and, as a rule, good light resistance. They are particularly suitable for direct dyeing. By the method of packing with reagents on the dye for cellulose fibers, valuable and durable pabivka are also obtained if the dyes are fixed by heat treatment in the presence of silk on a stuffed material. After dyeing or stuffing with reactive dyes, it is necessary to remove the non-fixed dye as completely as possible. To this end, the painted material is rinsed with warm and cold water and subjected to saponification in the presence of non-ionic disnergiruyushchimi and / or wetting agents. The dispersed dyes described above, which do not contain metal atoms or sulfo groups bound in the complex, are used in top-standard form with added doping properties, such as spent sulphite-cellulose solution or synthetic washing liquids, or they are used for dyeing in combination with various wetting-1x and dispersing agents. As a rule, it is necessary to convert the used dyes before dyeing and dye and preparation containing a disinfecting agent and a finely distributed cradle into such a form that, when diluted with a red preparation with water, to obtain a fine dnsner1; () the bath is a means, iredouireydun1, its deposition of pigments, nln carry out the process of dyeing under the pressure. at temperatures above, panrnmer at 20 ° C, in an appropriate case in acetic acid medium. As a means of preventing precipitation of nigmeites, aromatic carboxylic acids can be used, for example, benzoic or salicylic acids / phenyls, phenol, such as o-yln ;; - oxindiffs; 1L, aromatic halogenoedigonn, panrime chlorobenzene, o-dichlorobenzene; tpichlorobenzene, phenylmethyl carbinol or dimethyl. The resulting disperse redtels are especially useful for cranes using the so-called thermofuction method, in which the tissue being dyed is impregnated with a water dissolver: a dye containing expediently containing 1–50% of urine and thickener is sodium impurity, at temperatures not less than 60 Å. , n wring out according to the usual method. For fixation 1 and dispersed cradle of proanthia, such a fabric is heated to temperatures above 100 ° C, for example, to 180-10 ° C, preferably after the previous drying, anti-aging, in a tenley air stream. Of particular interest is the newly denoted heat-setting method for dyeing blended fabrics from polyester fibers and cellulose fibers, in particular cotton, dispersed koreiteli. In this case, in addition to the dye used in accordance with the invention, the poulet liquid contains dyes suitable for dyeing cotton, such as direct, vat or reactive dyes, in particular, representatives of those above the reactive dyes. The splices obtained with the help of disiser dyes on polyester fibers are expediently subjected to additional treatment, for example, by agglomeration with an aqueous solution of an ion-free detergent. The indicated disperse dyes are also iridescent for dyeing blended fabrics from polyester and wool fibers, and the wool does not dye and can be marginal: wool dye. They are also iridescent for dyeing niolefinic fibers, especially nolypropylene, cellulose triacetate, and for dyeing, unreduced (by sublimation method) using auxiliary dyes. These dnsperse redtels can be used, as well as metal complex dyes, for the cracking of a mass of iolamides. Doped, chromium and cobalt-containing dyes, which are free from sulfogrunn, can be concentrated in water and in a weakly acidic medium. Oi-n-i are suitable for dyeing and packing such.

Example II 1. 2 parts of a chromic complex of a mixture of dyes of formulas 4000 parts of water are dissolved, and 100 parts of a well-moistened wool are added to the dye obtained in this way at 40-50 ° C. Then 1 hour of 40% acetic acid is added, heated to boiling for half an hour and stained for 1 hour with kin. Finally wash the coat with cold water and dry. Wool is now dark blue in color, and dyeing is uniform, resistant to washing, resistant to rolls, light fastness, resistant to deciling and resistant to carbonization. Dyeing in dark blue is also obtained without adding acetic acid to the dye bath or if instead of niepCTH, suiperpolamide fibers (nylon) are dyed according to the indicated method. ri p and m e p 2.
