The novel diresorcinyl-alkoxy- and -aryloxy-s-triazines are composed according to the formula wherein Ri is C2-C3o alkyl; C2-C30 alkenyl; C5-C12 cycloalkyl-unsubstituted or C5-C12 cycloalkyl-C1-C5 alkyl mono or poly substituted, C? -C5alkoxy-C? -C? 2 alkyl; amino-C? -C? 2 alkyl; C1-C5 monoalkylamino-C? -C? 2 alkyl; C1-C5-dialkylamino-C1-C12-alkyl; a radical of the formula R2, R3 and R, independent of each other, are hydrogen, hydroxyl, C1-C30 alkyl, C1-C30 alkenyl, Rs is hydrogen; or C1-C5 alkyl; mi is 0 or 1; and is not 1 to 5. Alkyl means a branched or unbranched hydrocarbon radical, for example methyl, ethyl, propyl, isopropyl, n-butyl, secondary butyl, t-butyl, 2-ethylbutyl, n-pentyl, isopentyl, -methylpentyl, 1,3-dimethylbutyl, n-hexyl, 1-methylhexyl, n-heptyl, isoheptyl, 1, 1,3, 3-tetramethylbutyl, 1-methylheptyl, 3-methohyl, n-octyl, isooctyl, 2-ethylhexyl , 1,1,3-trimethylhexyl, 1, 1,3,3-tetramethylpentyl, nonyl, undecyl, 1-methylundecyl, dodecyl, 1,1,3,3,5,5-hexamethylhexyl, tridecyl, pentadecyl, hexadecyl, heptadecyl or octadecyl. Alkoxy radicals are straight or branched chains, for example methoxy, ethoxy, propoxy, butoxy or pentyloxy. C5-C12 cycloalkyl means, for example, cyclopentyl, cycloheptyl, cyclooctyl, cyclononyl, cyclodecyl, cycloundecyl, cyclododecyl and particularly cyclohexyl. in which, alkenyl includes inter alia allyl, isopropenyl, 2-butenyl, 3-butenyl, isobutenyl, n-penta-2,4-dienyl, 3-methyl-but-2-enyl, n-oct-2-enyl, n-dodec-2-enyl, isododecyl, n-dodec-2-enyl, n-octadec-4-enyl, or 3, 7, 11, 11-tetramethyl-2,6,6-undecatrienyl. Preference is given to the compounds of the formula (1) in which R5 is hydrogen. Preference is also given to the compounds of the formula (1) in which Ri is C2-C30 alkyl, particularly C-C3o alkyl, and very particularly C6-C30 alkyl. Of these compounds, particular preference is given to compounds in which Ri is a 2-decihexadecyl radical. Other interesting compounds of formula (1) are those in which Ri are C-C3o alkyl radicals. Of these compounds, particular preference is given to those in which Ri is an isooctadecyl radical, an n-octadecyl or a 2-hexadecyl. Particularly interesting compounds of the formula (1) are those in which i is a 3- to 2-chain, and a couple of a -ethylhexyl radical. Other illustrative representatives of the novel diresorcinyl-alkoxy- and -aryloxy-s-triazines are given in the tables below: The novel resorc n -a cox- and -ar ox -str az nas are prepared, for example, by reaction of cyanuric chloride with the alcohol Ri-OH to give the respective aryloxy- or alkaloxy-dichloro-s-triazines of the formula (2). The novel compounds of the formula (1) are obtained in a second reaction step of a Friedel-Crafts reaction. The reaction can be represented diagrammatically as follows: (twenty-one) The first step of the reaction is generally carried out in the presence of a solvent, for example acetone, methyl ethyl ketone, dimethylacetamide, toluene or xylene. Here the temperatures are between 0 and 130 ° C, particularly from 20 to 70 ° C; the reaction times are from 1 to 48 hours, preferably from 2 to 10 hours. The solvent normally employed in the second reaction step is toluene, nitrotoluene, nitrobenzene, anisole, xylene, benzene, sulfolane, chlorobenzene, dichlorobenzene, hydrocarbons (for example isooctane), chlorinated hydrocarbons, nitroalkanes, carbon disulfide, sulfur dioxide and mixtures of the solvents mentioned.
Here the temperatures range from -10 to 200 ° C, in particular from 0 to 100 ° C. Reaction times range from 1 to 100 hours, preferably from 2 to 50 hours. The second reaction step is generally carried out in the presence of a catalyst. Examples of such catalysts are: aluminum chloride, aluminum bromide, tin chloride, titanium tetrachloride, boron trifluoride and other Lewis acids. Here the catalyst is used in an amount of 0.1 to 3 mol per mole of reactive chlorine. Frequently a dealkylation of the alkoxy radical is observed in the Friedel-Crafts reactions with dichloroalkoxy-s-triazines. Under the conditions according to the invention, i.e. control of the temperature, amount of catalyst and measured addition of the catalyst, the reaction generally proceeds particularly smoothly and without appreciable dealkylation. Another synthetic method for the novel diresorcinyl-alkoxy-and-aryloxy-s-triazines involves the reaction of cyanuric chloride with resorcinol to obtain the 2-chloro-4,6-resorcinyl triazine (compound of the formula (20)) in the first reaction step and reacting it with Ri-OH to obtain the compound of the formula (1) in a second reaction step, according to the following equation: (20) d) The p-hydroxyl groups of the resorcinyl radicals of the novel diresorcinyl-alkoxy-and-aryloxy-s-triazines with the formula (1) can be further alkylated using alkylating agents X-R5 (X = C1, Br, I, F ) to give the alkoxy derivatives corresponding to the formula where R and R are defined as for formula (1). Other usable alkylating agents are the epoxides, tosylates, dialkyl sulfates and ethyl glycidyl ethers. The compounds of the formula in which R 'i is a C 8 -C 2 radical or branched alkyl; a radical of the formula m 'i is 0 or 1 and n' i is 1 to 5, obtained in the first reaction step are novel compounds. These are also provided by the invention. The novel diresorcinyl-alkoxy-and-aryloxy-s-triazine of the formula (1) have an absorption maximum around the nm, that is, the compounds are ultraviolet-sensitive. The compounds are therefore particularly applicable as ultraviolet radiation filters, that is, to protect organic materials that are sensitive to ultraviolet light, in particular human and animal skin and hair, from the harmful effects of ultraviolet radiation. Therefore, these compounds are applicable as light-protecting agents in cosmetic, pharmaceutical and veterinary medicine preparations. They can be used both in dissolved form and in the micronized state. Therefore, the present invention also relates to compounds of a formula (1) in micronized form, wherein Ri is C? -C alkyl; -C30 alkenyl; C5-C12 cycloalkyl-unsubstituted or C5-C12 cycloalkyl-C1-C5 alkyl mono- or poly-substituted, C-C5alkoxy-C? -C? 2 alkyl; amino-C? -C? 2 alkyl; C1-C5 monoalkylamino-C? -C? 2 alkyl; C1-C5-dialkylamino-C1-C12-alkyl; a radical of the formula (1a) - (CH2) - (O) - / \; 0b) m.

If the novel ultraviolet absorbers are in micronized form they usually have a particle size from 0.02 to 2 μm, preferably between 0.05 and 1.5 μm, very particularly between 0.1 and 1.0 μm. Micronized methods are described, for example, in GB-A-2303549. The grinding apparatus that can be used to prepare the novel micronized organic ultraviolet absorbers is, for example, a jet, ball or hammer mill, preferably a stirred mill. The milling is preferably carried out using a grinding aid, for example an alkylated vinyl pyrrolidone polymer, a copolymer of vinyl acetate-vinyl pyrrolidone, an acylglutamate or, in particular, a phospholipid. Due to their lipophilic nature the compounds (1) can be easily incorporated into cosmetic formulations containing oils or fats, particularly when Ri is a branched alkyl radical of more than 8 carbon atoms. The invention also provides a cosmetic preparation comprising at least one compound of the formula (1) and cosmetically compatible carrier and auxiliary agents. The novel light protection agents have, for cosmetic use, an average particle size in the range between 0.02 and 2 μm, preferably between 0.05 and 1.5 μm, very particularly between 0.1 and 1.5 μm. As mentioned above, the novel ultraviolet radiation absorption agents can be brought to the desired particle size by means of the usual grinding methods. The grinding is preferably carried out in the presence of grinding aids of 0.1 to 30% by weight, preferably 0.5 to 15% by weight, based on the weight of the ultraviolet absorption agent.

The novel cosmetic preparation can be formulated as a water-in-oil or oil-based emulsion. e in water, as an oil-in-alcohol lotion, as a vesicular dispersion of an ionic or nonionic amphiphilic lipid, as a gel, as a solid stick or as an aerosol formulation. As a water-in-oil or oil-in-water emulsion, the cosmetically compatible auxiliary preferably comprises from 5 to 50% of an oily phase, from 5 to 20% of an emulsifier and from 30 to 90% of water. The oily phase may comprise any oil applicable for cosmetic formulations, for example one or more carbohydrate oils, a wax, a natural oil, a silicone oil, a fatty acid ester or a fatty alcohol. The above mono- and polyols are eio, sopropane, prop in g, hexylene glycol glycerol and sorbitol. Any conventional emulsifier can be used for the novel cosmetic preparation, for example one or more ethoxylated esters of natural derivatives, for example polyethoxylated esters of hydrogenated castor oil; or a silicone oil emulsifier, for example silicone polyol; an optionally ethoxylated fatty acid soap; an ethoxylated fatty alcohol; an optionally ethoxylated sorbitol ester; or an ethoxylated glyceride. The cosmetic preparation can also contain other components, for example emollients, emulsion stabilizers, skin moisturizers, skin tanning accelerators, thickeners, for example xanthan, humectants, for example glycerol, preservatives, fragrances and dyes. The novel cosmetic preparation is notable for its excellent protection of human skin from the harmful effects of sunlight. The novel diresorcinyl-alkoxy-and-aryloxy-s-triazines are notable for their high thermal stability and are therefore used as stabilizers of organic polymers, in particular in surface coatings, against damage caused by light, oxygen and oxygen. hot. The material stabilized by the use of the novel compounds is notable for its excellent resistance to weathering and to the effects e a uz and for the excellent photostability of the built-in stabilizer. The materials to be stabilized can be, for example, oils, fats, waxes or biocides. Its use in polymeric materials, such as those present in plastics, rubbers, paints, surface coatings, photographic material or adhesives is of particular interest. Therefore the invention also provides a composition containing (A) an organic material sensitive to damage by light, oxygen and / or heat, and (B) a compound of the formula (1) as a stabilizer. The invention also relates to a method of stabilizing organic material from damage by light, oxygen and / or heat, wherein a compound of the formula (1) is added as a stabilizer to such a material, and also to the use of the compound of the formula (1) to stabilize organic material. The amount of stabilizer to be used depends on the organic material to stabilize and the intended use of the stabilized material. In general, the novel composition comprises, for every 100 parts by weight of the component (A), between 0.01 and 15 parts by weight, in particular 0.05 to 10 parts by weight and especially 0.1 to 5 parts by weight of the stabilizing component (B ). it is at least or can not be a mixture of two or more compounds of the formula (1). The novel composition may comprise, in addition to the novel compounds, other stabilizers or other additives, for example antioxidants, other light-protecting agents, metal deactivators, phosphites and phosphonites. The type and quantity of the additional stabilizers is determined by the type of substrate to be stabilized and by its intended use; frequently between 0.1 and 8% by weight is used, based on the polymer to be stabilized. The incorporation into organic polymers, for example in organic synthetics, particularly in thermoplastics, polymers, can take place by the addition of the novel triazine compounds and other optional additives by methods customary in the art. The incorporation can take place expediently before or during forming, for example by mixing powdered components or by adding the stabilizer to the melt or solution of the polymer, or by applying the dissolved or dispersed compound on the polymer, with subsequent evaporation of the solvent if necessary. In the case of elastomers, these can also be stabilized as grids. Another possible way to incorporate the novel mixtures into polymers involves their addition before or during the polymerization of the corresponding monomers or their cross-linked state. Stabilized polymer compositions obtained in this way can be converted into formed articles, for example fibers, films, tapes, shapes, sheets, multiple wool sheets, tubes and other profiles by conventional methods, for example by hot pressing, spinning , extrusion or injection molding. The polymers stabilized in this way are notable for their high resistance to weathering, especially for their high resistance to ultraviolet light. Therefore they retain their mechanical properties and their color and brightness even when used outdoors for long periods of time. In the following examples the percentages are by weight. The amounts used in the case of the diresorcinyl triazines refer to the pure substance. Examples of preparations.
