Definitions

• Halogen preferably stands for Cl.
• suitable Ar radicals are, in particular, phenyl or phenylene radicals, which can be substituted by X1-X4.
• Salicylic acid and salicylaldoxime are preferably used.
• the aforementioned complexing agents can also be used in any mixture with one another, for example a mixture of salicylic acid and salicyloloxime.
• Suitable copper II salts B are e.g. CuCl2, CuSO4 ⁇ 5H2O, Cu (OAc) 2 ⁇ H2O or CuCO3 ⁇ Cu (OH) 2.
• Suitable dispersants I and II are commercially available products which are obtained by sulfite or force digestion of the wood.
• Suitable type III dispersants are especially the alkali and ammonium salts of condensation products of aromatic sulfonic acids with formaldehyde, such as e.g. Formaldehyde condensation products from (alkyl) -naphthalenesulfonic acids, mixtures of naphthalene and benzenesulfonic acids, mixtures of cresols and naphthalenesulfonic acids, sulfated diphenyl ethers, sulfated diphenyl thioethers, sulfated diphenyl sulfones as well as mixtures of cycloalkanones and alkali bisulfite.
• formaldehyde such as e.g. Formaldehyde condensation products from (alkyl) -naphthalenesulfonic acids, mixtures of naphthalene and benzenesulfonic acids, mixtures of cresols and naphthalenesulfonic acids
• the ratio of A: B in the preparation is 0.8 to 2.4 moles of component A to 1 mole of component B.
• the finished preparations generally consist of 10 - 80% by weight A + B, 78-18% by weight of C and optionally 12-2% by weight of other auxiliaries, the sum of course must be 100%.
• Examples of the other aids that may be present are: Dedusting agents, adjusting agents, light stabilizers, buffer substances (i.e. pH regulators) etc., as well as residual moisture.
• the amount of the preparations according to the invention is 0.02-3, preferably 0.1-0.5% by weight, based on the fiber material.
• Suitable fiber materials are those made of synthetic polymers, such as polyurethanes and synthetic polyamides.
• the dyeings on these fibers can be produced in a conventional manner using both metal complex dyes and acid dyes.
• the metal complex dyes in particular the 1: 2 chromium or 1: 2 cobalt complexes of mono- or diazo compounds, which are described in large numbers in the literature and are commercially available, are preferred. These dyes can also contain 1-2 sulfo groups.
• Suitable acid dyes are, in particular, those types which are usually used in combination with the metal complex dyes.
• the treatment of the polyamide materials with the copper-containing preparations produced according to the invention can take place before, during or after, preferably during the coloring.
• the dyeings are made by conventional methods, i.e. in the exhaust process on the jet dyeing machine, the jigger, the reel runner or a reel dyeing machine or on a continuous machine according to the known padding or impregnation processes.
• the main advantage of the preparations according to the invention compared to the prefabricated copper complexes is that they have no great mechanical and procedural effort can be produced.
• the powder is then dedusted in a Lödige mixer with the addition of 7.40 parts of a dedusting agent based on mineral oil.
• aqueous dispersion consisting of 191.00 parts of water (as template) 19.37 parts Salicylaldoxim (98%) 13.85 parts of sodium hydroxide solution (40%) 92.88 parts of lignin sulfonate (after sulfite digestion) liquid (33.6% dry) 106.38 parts Llgninsulfonat (after force application) liquid (29.4%) 4.78 parts water (for rinsing) 17.37 parts.
• the powder obtained can be used immediately.
• Example 3 If 20 parts of the batch mentioned in Example 3 are mixed with 80 parts of the liquid preparation in Example 5 followed by spray drying (E. 140 ° C./A. 70 ° C.), a preparation with a very high fine distribution in the dyebath or in the after-treatment bath and good light fastness-improving effect on colored polyamide.
• a mix of 80 parts of powder preparation from Example 3 20 parts of powder preparation from Example 5 is placed in a Lödige mixer and mixed.
• the powder mixture obtained can be used directly and has the same good effect as the preparation according to Example 7.
• the dye is then removed from the dye bath, rinsed and dried.
• the staining is carried out together with a comparative staining prepared without copper preparation according to the test of Adam Opel AG Tüsselsheim / FRG GM (Engineering Standards Europe) GME No 60 202 A / B exposed for 250 h in the xenon tester.
• the dye liquor is adjusted to pH 5.5 with the aid of a buffer mixture of monosodium phosphate and acetic acid. It is treated for one hour at 98 to 100 ° C, rinsed and dried.
• the coloring produced in this way shows a clearly improved light fastness.
