Definitions

• the present invention relates to a method for quenching or suppressing the fluorescence of substrates made of natural or synthetic polyamides with sulfonated UV absorbers which are treated or are to be treated with optical brighteners, and the material treated therewith.
• GB-A-2 174 731 discloses a process for the deletion or prevention of lightening effects on various substrates with UV absorbers, in which derivatives of the benzophenone series or of the non-sulfonated benzotriazole series are used as UV absorbers.
• the present invention thus relates to a method for quenching or suppressing the fluorescence of substrates made from natural or synthetic polyamides with UV absorbers, which substrates have been treated or are to be treated with optical brighteners, which method is characterized in that a substrate is applied to these substrates before or after the optical brightening sulfonated UV absorber of the formula wherein R1 is hydrogen, halogen, C1-C12-alkyl, C5-C6-cycloalkyl, C7-C9-phenylalkyl or sulfo, R2 is hydrogen, C1-C4-alkyl, C1-C4-alkoxy, halogen, hydroxy or sulfo, R3 is hydrogen, C1-C12-alkyl, C1-C4-alkoxy, phenyl, (C1-C8-alkyl) -phenyl, C5-C6-cycloalkyl, C2-C9-alkoxycarbonyl, halogen

• Examples of compounds of the formula (3) are the sodium salt of 3- (4 ′, 6′-diphenyl-s-triazin-2′-yl) -4-hydroxy-6-methoxy-, 3- (4 ′, 6 ′ -diphenyl-s-triazin-2'-yl) -4-hydroxy-6-ethoxy- and 3- (4 ', 6'-diphenyl-s-triazin-2'-yl) -4-hydroxy-6-propoxy -benzenesulfonic acid.
• the compounds of formulas (1) to (3) given above are e.g. known from WO-A-84/02365 and WO-A-86/03528 and can be prepared by known methods.
• UV absorbers Mixtures of UV absorbers can also be used.
• the UV absorber is advantageously applied to the substrate from an aqueous medium.
• the UV absorber can be impregnated and held at room or elevated temperature, for example between 20 and 90 ° C. for 30 minutes to all known methods of dyeing or printing, such as treatment in a long bath at temperatures from 20 to 140 ° C. 48 hours depending on the temperature, padding and fixing by the action of saturated steam, superheated steam, hot air, treatment with high-frequency or contact heat, are applied and fixed on the substrate.
• the UV absorber can also be used in so-called thermal printing.
• the UV absorber can be fixed on the substrate by mediating organic high polymers, for example in the form of aqueous or non-aqueous paints, or using the pigment printing method.
• UV absorber The choice of application and fixing method and the amount of UV absorber depend on the substrate, the dyes used, the optical brighteners and their fastness and the properties of the UV absorbers used. In general, good extinguishing effects are obtained when the UV absorber is used in an amount of 0.1 to 5% of the weight of the goods.
• the UV absorber can be used according to the invention after the optical brightening, or before, during or after the dyeing or printing of a substrate treated with an optical brightener.
• the treatment with the UV absorber can also take place before, during or after dyeing or printing, before the substrate in question is treated with an optical brightener. This is the case, for example, with items of clothing that are washed after use will.
• Commercial detergents or soaps for the household today mostly contain optical brighteners to make the laundry washed with them appear whiter. If light-colored dyed or printed textiles are now washed with such a detergent, a different color tone results after drying than before. This is particularly objectionable for light colors such as blue, rosé, beige etc.
• optical brightening effects are deleted or suppressed locally or over the entire surface.
• optical brightening effects are produced by commercially available optical brighteners, for example known anionic or cationic optical brighteners and dispersion brighteners as are used in detergents.
• optical brighteners are derivatives of bis (triazinylamino) stilbene disulfonic acid, triazolyl derivatives of stilbene sulfonic acids, bis (stilbene) compounds, pyrazoline, coumarin, bis (benzimidazolyl), bis (oxazolyl), naphthalimide and cyanine -, Benzoxazolyl and Oxacyanin derivatives called.
• Textile materials made from natural or synthetic polyamides are used as substrates and e.g. Yarns, fabrics, knitted or nonwovens understood.
• the textile materials can also consist of mixtures of polyamides with other fibers.
• both liquors are taken in at 50 ° C., the temperature is raised to 90 ° C. in 20 minutes and the dyeing is completed in 45 minutes. It is then rinsed cold and dried at 80 ° C.
• Example 1 or 2 The procedure is as noted in Example 1 or 2, i.e. two dyeings are prepared with 0.01% of the dye of the formula (III) without and with 1% of the UV absorber of the formula (VII). If these dyeings are washed with the brightener-containing detergents, the conventional dyeings undergo a clear change in shade to brilliant purple, while the dyeings containing compound (VII) are practically unchanged.
• Each 20 g piece of a bleached wool mousse line is dyed with and without UV absorber.
• the dye liquors are charged with 2% ammonium sulfate, 2% of the sulfonated reaction product from naphthalene and formaldehyde and 0.005% of the dye of formula (X).
• Fleet A receives no further additives, while Fleet B receives 1% of the UV absorber of the formula (X)
• the dyeing is carried out at a liquor ratio of 1:50 by entering at 50 ° C., heating to 95 ° C. in 30 minutes and treatment for 45 minutes. Then the samples are rinsed well cold, spun and dried at 80 ° C.
• the dye is replaced by 0.015% of the dye of the formula (V), so there are color shades which behave differently when washed in wash liquors containing brighteners: the pattern containing UV absorber remains unchanged while the conventionally colored after redder / brilliant unbeatable.
