    The invention relates to silicon-containing nitrokrasite m for the dyeing of polymeric organic compounds of silicone products and inorganic materials, as well as active dyes for synthetic or natural fibers of plant or animal origin. V Bonjour (Dissertations, 197O, Technical University, Zurich) and Hashimoto (Eagshi kagaki, 80 (i960), 13991404) describe the preparation of azo dyes based on trimethylsilylanilines by the reaction of these silicon compounds with diazotized aromatic amines. Dyes on this basis cannot be retained on the scrubbing substrates due to the inactive methyl groups of the silicon atom and therefore have not received any industrial value. Dyes containing a trio (trimethylsiloxy) silylalkylamine radical are described in the specifications of U.S. 3,888,891, 3,963,744 and 3,981,859. In this case, it is mainly about HINO-, indigo-, TIOINDIGO-, phthaloianin-an and adkra sieve lx. Based on the fact that the production of (trimycypsyloxy) -silyl-lilamine is based on hard-to-reach raw materials with a low yield, dyes based on them also due to the inactivity of the siloxy-groups, were used for dyeing certain polysiloxanes. To remixing dyes containing a hydrolusable group are described, for example, in the specifications of U.S. Patents 2,925,313, 2,927,839, 2,931,693, B.934,459, 2,955,398, 2,959,899 and 2,963,338. arylamino were used to prepare azo dyes. or amino-arylalkoxysilanes as. silicon-containing starting components. These dyes show good durability on glass fibers, on natural fibers, such as wool, silk and cotton fibers, and on synthetic fibers. Their disadvantage is the complex and expensive preparation of the starting silicon-containing amino amino compound. Silicon-containing nitro dyes are not described in the literature. The aim of the invention is to obtain new silicon-containing nitro-paints in a simple manner from readily available raw materials and in a good yield. Dye components should, if possible, be associated with polyopic structures with homopolar bonds. Further, the dyes should, according to their resistance to silicones, tweake to the highest and most specific requirements and durable to paint polymeric materials and especially silicone. new products. found that silicon-containing nitro dyes of the general formula CH2-NH- «r (N02), r Xb-5 | -2 are capable of durable dyeing polymer and especially silicone materials,. at the same time, they are satisfied with the specific requirements for silicones, such as thermal stability. In the general formula, the indices denote: X - the same or different hydrolysis of your group or siloxane radical; - Co-, alkylene, which may include oxygen atoms, and also contain cyclic units; C and C may form a cyclic radical; R is a monovalent organic radical; ., sig - substituted or unsubstituted aryl; with and b- 1-3. The proposed method of producing new silicon containing nitro dyes is simple and is realized by the reaction of silanes or siloxanes of the general formula: Xb-5i, where X, Z. , R, b have the indicated values, with nitroanilines {of the general formula (N02) c ,, where a and d have the indicated values, at 1OO-200 ° C in the stoichiometric ratio of epoxy and amino groups of the starting compounds. The process can be carried out in a solvent such as, for example, methanol, ethanol, acetone, dimethylformamide, alkyl esters of carboxylic acids,
