Description: TRISARYH,3,5-TRIAZINE ULTRAVIOLET LIGHT ABSORBERS BACKGROUND OF THE INVENTION Field of the Invention This invention relates generally to novel trisaryl-1 ,3,5-triazine compounds containing active (acidic) hydrogen atoms and the use thereof to protect against degradation by environmental forces, inclusive of actinic radiation (such as ultraviolet light), oxidation, moisture, atmospheric pollutants and combinations thereof. Description of Related Art Exposure to sunlight and other sources of ultraviolet radiation is known to cause degradation of a variety of materials, especially polymeric materials. For example, polymeric materials such as plastics often discolor and/or become brittle as a result of prolonged exposure to ultraviolet light. Accordingly, a large body of art has been developed directed towards materials such as ultraviolet light absorbers and stabilizers which are capable of inhibiting such degradation. A class of materials known to be ultraviolet light absorbers are trisaryl-1 ,3,5-triazines, in which at least one of the aryl rings has a hydroxyl group ortho to the point of attachment to the triazine ring. In general this class of materials is well known in the art. Disclosures of a number of such trisaryl-1 ,3,5-triazines, as well as processes for preparing and uses thereof, can be found in the following publications, all of which are incorporated by reference herein for all purposes as if fully set forth: US3118887, US3242175, US3244708, US3249608, US3268474, US3423360, US3444164, US3843371 , US4619956, US4740542, US4775707, US4826978, US4831068, US4962142, US5030731 , US5059647, US5071981 , US5084570, US5106891 , US5185445, US5189084, US5198498, US5288778, US5298067, US5300414, US5322868, US5354794, US5364749, US5369140, US5410048, US5412008, US5420204, US5461151 , US5476937, US5478935, US5489503, US5543518, US5538840, US5545836, US5563224, US5575958, US5591850, US5597854, GB1033387, CH480091 , CH484695, EP-A-0434608, EP-A-0444323, EP-A-0532006, EP-A-0649841 , EP-A-0693483, EP-A-0704560, WO94/05645, W095/22959 and W096/28431. Typically, the aforementioned aryl ring with the hydroxyl group ortho to the point of attachment to the triazine ring is based on resorcinol and, consequently, this aryl ring also contains a second substituent (either a hydroxyl group or a derivative thereof) para- to the point of attachment to the triazine ring. This second substituent can be "non-reactive," as in the case of an alkyloxy group, or "reactive" as in the case of a hydroxyalkyloxy (active hydrogen reactive site) or (meth)acryloyl (ethylenic unsaturation reactive site) group. For the purposes of the present invention, the former are referred to as "non-bondable" trisaryl-1 ,3,5-triazines and the latter are referred to as "bondable" trisaryl-1 , 3,5-triazines. Many polymer additives (such as ultraviolet light stabilizers) may suffer from a disadvantage that they volatilize or migrate out of the polymer substrate to be protected, or that they are adsorbed (chemically or physically) by one or more systems components (such as pigments), thereby diminishing their effectiveness. Bondable stabilizers have a potential advantage in this respect in that, depending on the bondable functionality and the particular polymer system to be stabilized, they can be chemically incorporated into a polymer structure via reaction of the bondable functionality either during polymer formation (such as in the case of polymerizing monomers or a crosslinking polymer system) or subsequently with a preformed polymer having appropriate reactive functionality. Accordingly, due to such bonding, migration of these UV absorbers between layers of multi-layer coatings and into polymer substrates is greatly reduced. Several of the previously incorporated references disclose bondable trisaryl-1 ,3,5- triazines. For example, previously incorporated US3423360, US4962142 and US5189084 disclose various bondable trisaryl-1 ,3,5-triazines and the incorporation of these compounds into polymers by chemical bonding. However, the inventors are unaware of any prior art which discloses the novel functionalized trisaryl-1 ,3,5-triazines of the present invention. SUMMARY OF THE INVENTION The present invention provides a new class of bondable trisaryl-1 ,3,5-triazines in which an aryl ring attached to the triazine ring (and preferably an aryl ring containing a hydroxyl group or "latent" hydroxyl group ortho- to the point of attachment to the triazine ring) is substituted with a bondable group, containing one or more active (acidic) hydrogen containing groups para- to the point of attachment to the triazine ring. As examples of such active (acidic) hydrogen containing groups may be mentioned 1 ,3-dicarbonyls, 1 ,3- diketones, 1 ,3-diesters (malonate esters), 1 ,3-ketoesters, beta-carbonyl cyano compounds, 1 ,3-sulfur compounds, 1 ,3-disulfones and 1 ,3-disulfoxides. More specifically, the new trisaryl-1 ,3,5-triazines of the present invention have the following general formulas (I), (II) and (III): wherein each X is independently selected from hydrogen and a blocking group; each of Y and Z is independently selected from an aryl ring of the general formula (IV) each R is independently selected from a hydrogen, a hydrocarbyl group and a functional hydrocarbyl group; each R 1 , R 2 , R 4 , R 4' and R 4" is independently selected from hydrogen, hydrocarbyl, functional hydrocarbyl, -O(hydrocarbyl), -0(functional hydrocarbyl), -SR, halogen, -S0 2 R, -S0 3 R, -COOR, -COR, -OCOR, -NRR and cyano; and each R 3 is independently selected from -R, -OR, -SR, halogen, -S0 2 R, -SO s R, -COOR, -COR, -NRR and cyano; characterized in that at least one R group of a 4-position -OR group is selected from a group of the general formulas (V), (VI) and (VII): wherein A is selected from -0(0)C-; -C(O)-; -SO-; -S0 2 -; and -OS0 2 -; each of A 1 and A 3 is independently selected from -COOR 7 ; -COO " M + ; -C(0)R 7 ; -C(0)NR 7 R 8 ; -CN; -N0 2 ; -SOR 7 ; -S0 2 R 7 ; -S0 2 OR 7 ; and -S0 2 NR 7 R 8 ; A 2 is selected from -C(O)-; -R 9 C(0)-; -R 9 OC(0)-; -SO-; -R 9 SO-; -S0 2 -; -R 9 S0 2 -; and -R 9 OS0 2 -; M + is a cationic moiety; each of R 5 and R 9 is independently a hydrocarbylene group; R 6 is selected from H and an alkyl of 1-4 carbon atoms; and each of R 7 and R 8 is independently selected from H, a hydrocarbyl group and a functional hydrocarbyl group. These tris-aryl-1 ,3,5-triazines of the present invention have the added benefit of being capable of chemically bonding to appropriate polymer systems via the acidic active hydrogen. Since, in the above formulas, the acidic active hydrogen is from an active methylene or methine group, the further advantage of very stable carbon-carbon bonding is possible. These trisaryl-1 ,3,5-triazines may in general be prepared via a number of procedures, but preferably by reacting a trisaryl-1 ,3,5-triazine precursor, having at least one aryl ring with an amino, amido and/or hydroxyl group containing -OR moiety para to the point of attachment to the triazine ring (and preferably also a hydroxyl group ortho to the point of attachment to the triazine ring), with an appropriate compound or compounds to functionalize the para position -OR group with a group of the above formula (V) and/or (VI). Further preferred process details are disclosed below. The novel trisaryl-1 ,3,5-triazines of the present invention are particularly useful as ultraviolet light absorber agents for stabilizing a wide variety of materials including, for example, organic compounds, oils, fats, waxes, cosmetics, dyes and biocides, and particularly various organic polymers (both crosslinked and non-crosslinked) used in applications such as photographic materials, plastics, rubbers, paints and other coatings, and adhesives, such as disclosed in a number of the previously incorporated references. The present invention, consequently, also relates to (1) a method of stabilizing a material which is subject to degradation by actinic radiation (e.g., an organic material such as an organic polymer in the form of a film, fiber or shaped article) by incorporating into said material an amount of an actinic radiation stabilizer composition effective to stabilize the material against the effects of actinic radiation, wherein the actinic radiation stabilizer composition comprises the inventive trisaryl-1 ,3,5-triazines; and (2) the material so stabilized. The novel trisaryl-1 ,3,5-triazines of the present invention are also effective as ultraviolet light screening agents in applications such as sunscreens and other cosmetic preparations, capstock layers for extruded polymers, dyed fibers and laminated UV- screening window films, among others. The present invention, consequently, also relates (1) to a method of protecting a substrate against degradation by actinic radiation by applying to the substrate an actinic radiation screening layer (e.g., a coating film or capstock layer) containing an actinic radiation screening composition in an amount effective to reduce the amount of actinic radiation impinging on the substrate, wherein the actinic radiation screening composition comprises the inventive trisaryl-1 , 3, 5-triazines; and (2) the substrate so protected. The novel trisaryl-1 ,3,5-triazines of the present invention may also employed to form light stabilizing compositions. Such light stabilizing compositions may include a variety of other components known in the art including other ultraviolet absorbers and stabilizers, antioxidants and the like. These and other features and advantages of the present invention will be more readily understood by those of ordinary skill in the art from a reading of the following detailed description. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The Novel Trisaryl-1.3.5-Triazines As indicated above, the trisaryl-1 , 3, 5-triazines in accordance with the present invention are compounds of the general formulas (I), (II) and (III). The term "hydrocarbyl" in the context of the present invention, and in the above formulas, broadly refers to a monovalent hydrocarbon group in which the valency is derived by abstraction of a hydrogen from a carbon atom. Hydrocarbyl includes, for example, aliphatics (straight and branched chain), cycloaliphatics, aromatics and mixed character groups (e.g., aralkyl and alkaryl). Hydrocarbyl also includes such groups with internal unsaturation and activated unsaturation. More specifically, hydrocarbyl includes (but is not limited to) such groups as alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkenyl, cycloalkenyl and alkynyl, preferably having up to 24 carbon atoms. A hydrocarbyl may optionally contain a carbonyl group or groups (which is/are included in the carbon count) and/or a heteroatom or heteroatoms (such as at least one oxygen, sulfur, nitrogen or silicon), in the chain or ring. The term "functional hydrocarbyl" in the context of the present invention, and in the above formulas, broadly refers to a hydrocarbyl possessing pendant and/or terminal "reactive" and/or "latent reactive" functionality and/or leaving groups. Reactive functionality refers to functionality which is reactive with common monomer/polymer functionality under normal conditions well understood by those persons of ordinary skill in the relevant art. As examples of reactive functionality may be mentioned active hydrogen containing groups such as hydroxyl, amino, carboxyl, thio, amido, carbamoyl and activated methylene; isocyanato; cyano; epoxy; ethylenically unsaturated groups such as allyl and methallyi; and activated unsaturated groups such acryioyl and methacryloyl, and maleate and maleimido (including the Diels-Alder adducts thereof with dienes such as butadiene). Latent reactive functionality within the meaning of the present invention and, as would clearly be understood by those persons of ordinary skill in the relevant art, refers to reactive functionality which is blocked or masked to prevent premature reaction. As examples of latent reactive functionality may be mentioned ketimines and aldimines (amines blocked, respectively, with ketones and aldehydes); amine-carboxylate salts; and blocked isocyanates such as alcohol (carbamates), oxime and caprolactam blocked variations. A "leaving" group within the meaning of the present invention and, as would clearly be understood by those persons of ordinary skill in the relevant art, is a substituent attached to the hydrocarbyl chain or ring which during reaction is displaced to create a valency on a carbon or hetero atom in the hydrocarbyl chain or ring. As examples of leaving groups may be mentioned halogen atoms such as chlorine, bromine and iodine; hydroxyl groups; quaternary ammonium salts (NT 4 + ); sulfonium salts (ST 3 + ); and sulfonates (-OSO 3 T); where T is, e.g., methyl or para-tolyl. Preferred functionality includes hydroxyl, -COOR 11 , -CR 12 =CH 2 , -CO-CR 12 =CH 2 , -OCO-CR 12 =CH 2 , -OCO-NH-R 8 , Cl, an isocyanate group, a blocked isocyanate group and -NHR 11 , wherein R 11 is selected from hydrogen and a hydrocarbyl (preferably of up to 24 carbon atoms); and R 12 is selected from hydrogen and an alkyl of 1 to 4 carbon atoms (preferably hydrogen and methyl). The term "hydrocarbylene" in the context of the present invention is a divalent hydrocarbon group in which both valencies derive by abstraction of hydrogens from carbon atoms. Included within the definition of hydrocarbylene are the same groups as indicated above for hydrocarbyl and functional hydrocarbyl with, of course, the extra valency (for example, alkylene, alkenylene, arylene, alkylaryl, etc.). The term "functional hydrocarbylene" in the context of the present invention refers to a species of hydrocarbylene possessing pendant reactive functionality, latent reactive functionality and/or leaving groups. The term "non-functional hydrocarbylene" in the context of the present invention refers generally to a hydrocarbylene other than a functional hydrocarbylene. The trisaryl-1 ,3,5-triazines in accordance with the present invention also relate to latent stabilizing compounds against actinic radiation of the general formulas (I), (II) and (III), wherein at least one of the hydroxyl groups on an aryl ring ortho to the point of attachment to the triazine ring is blocked, that is, wherein at least one X is other than hydrogen. Such latent stabilizing compounds liberate the effective stabilizers by cleavage of the O-X bond, e.g., by heating or by exposure to UV radiation. Latent stabilizing compounds are desirable because they have many favorable properties, i.e., good substrate compatibility, good color properties, a high conversion rate of the O-X group to an OH group, and a long shelf life. The use of latent stabilizing compounds is further described in US4775707, US5030731 , US5563224 and US5597854, which are incorporated herein for all purposes as if fully set forth. Latent stabilizing compounds comprising the trisaryl-1 ,3,5-triazines in accordance with the present invention can be prepared from compounds of the general formulas (I), (II) and (III) wherein at least one X is hydrogen by subjecting said compounds to a further reaction to form latent stabilizing compounds, as described in the immediately preceding incorporated references. As preferred examples of blocking groups X may be mentioned one or more of the following groups: allyl, -COR a , -S0 2 R b , -SiR c R d R e , -PR f R 9 or -POR'R 9 , -CONHR h , wherein each R a is independently selected from C-.-Cg alkyl, halogen-substituted C C 8 alkyl, C 5 -C 12 cycloalkyl, C 2 -C 8 alkenyl, -CH 2 -CO-CH 3 , C C 12 alkoxy, and phenyl or phenoxy which is unsubstituted or substituted by C C 12 alkyl, C C 4 alkoxy, halogen and/or benzyl; each R is independently selected from C,-C 12 alkyl, C 6 -C 10 aryl and C 7 -C 18 alkylaryl; each R c , R d and R e is independently selected from C r C 18 alkyl, cyclohexyl, phenyl and C<-C 18 alkoxy; each R f and R 9 is independently selected from C,-C 12 alkoxy, C^C^ alkyl, C 5 - C 12 cycloalkyl, and phenyl or phenoxy which is unsubstituted or substituted by C,-C 12 alkyl, C C 4 alkoxy, halogen and/or benzyl; and each R h is independently selected from C C 8 alkyl, C 5 -C 12 cycloalkyl, C 2 -C 8 alkenyl, -CH 2 -CO-CH 3 , and phenyl which is unsubstituted or substituted by C,- C 12 alkyl, C 2 -C 8 alkenyl, C^C^, alkoxy, halogen and/or benzyl.

The reaction to give the latent stabilizing compounds of the present invention of the general formulas (I), (II) and (III) in which X is -CONHR h can be carried out, for example, by reaction of the compounds of the general formulas (I), (II) and (III) wherein at least one X is hydrogen with the corresponding isocyanates. Furthermore, acylated compounds can be obtained by reaction with anhydrides, ketenes or esters, such as lower alkyl esters, as is well known to one skilled in the art. The above-described reagents may be used in approximately equimolar amounts or in excess, for example, from 2 to 20 mol with respect to the hydroxyl groups desired to be made latent in the starting compound of the general formula (I), (II) or (III). Catalysts customarily used for acylation, sulfonylation, phosphonylation, silylation or urethanation reactions may be used in forming the latent stabilizing trisaryl-1 ,3,5-triazines of the present invention. For example, acylation and sulfonylation reaction catalysts such as tertiary or quaternary amines, such as triethylamine, dimethyiaminopyridine or tetrabutylammonium salts, may be used for forming these latent stabilizing compounds. The reaction may be carried out in the presence of a solvent, such as relatively inert organics, e.g., hydrocarbons such as toluene and xylene, chlorinated hydrocarbons such as carbon tetrachloride or chloroform, or ethers such as tetrahydrofuran or dibutyl ether, or without a solvent. Alternatively, the reagent(s) may be employed as the solvent. The reaction temperature is usually between room temperature and about 150°C, for example, up to the boiling point of the solvent when a solvent is used. In preferred embodiments, each X is hydrogen.

As mentioned above, one particular advantage of the TRisaryl-1 , 3, 5-triazines of the present invention is that they can be chemically bound to substrates, such as polymers, thereby greatly reducing the migration of such UV absorbers, e.g., out of the substrate or away from the substrate surface. The bonding mechanism of the triazines of the present invention involves the formation of a bond (chemical and/or co-valent) between the active methylene and/or methine group and the "host" substrate, such as a polymer. Incorporation of the trisaryl-1 ,3,5-triazines of the invention can be brought about by copolymerization, copolyaddition, copolycondensation, by reaction with a polymer which carries suitable functional groups, or by grafting, in a manner as disclosed in previously incorporated US3423360 and US5189084. Bonding of the trisaryl-1 ,3,5-triazines of the invention can occur by polymerization or copolymerization. Polymerization or copolymerization can be carried out in solution, in an emulsion, in a dispersion, in the melt, or in the solid state as is well known to those in the polymerization art. In addition, bonding of the present trisaryl-1 , 3,5-triazine compounds of the present invention of the formulas (I), (II), or (III) can be brought about by copolyaddition or copolycondensation. Such incorporation can be made by addition during the synthesis of an addition polymer or copolymer or by condensation during the synthesis of a condensation polymer or copolymer by methods known to those skilled in the art. For example, compounds of the formulas (I), (II), or (III) containing the appropriate functional groups can be incorporated into polyesters, polyamides, polyurethanes, epoxy resins, melamine resins, alkyd resins, phenolic resins, polyurethanes, polycarbonates, polysiloxanes, polyacetals and polyanhydrides, to name but a few. In addition, compounds of the formulas (I), (II), or (III) can be bonded to a monomeric component which is then incorporated into a polymer or copolymer, e.g., by the free radical initiated addition or copolycondensation methods described above. Analagous methods are disclosed in, for example, US5459222 (incorporated by reference herein for all purposes as if fully set forth) for the bonding of benzotriazole and benzophenone stabilizers to diol precursors which are then incorporated by condensation polymerization into polyurethanes and polyesters to impart UV stabilizing properties to said polymers. Alternately, the trisaryl-1 ,3,5-triazines of the invention may also be bonded to polymers by reaction with an oligomer and/or polymer which carries suitable functional groups. For example, the present triazine compounds may be reacted by Michael addition to compounds or polymers containing pendant activated unsaturated groups. The present triazine compounds may also be reacted with a polymer and/or oligomer such as polyesters, polyurethanes and polydiols with other appropriate reactive end-groups, partially hydrolyzed polyvinylacetate, epoxy resins, polysiloxanes and polymers comprising maleic anhydride, either in the main chain or as a side-chain, by methods analagous to those well known to those of ordinary skill in the art. Grafting is yet another way of bonding of the present trisaryl-1 ,3,5-triazine compounds of the formulas (I), (II), or (III) to polymers and/or oligomers. Grafting may be carried out in solution, in the melt, or in the solid state to saturated polymers, e.g., polyoiefins and their copolymers such as polyethylene, polypropylene and poly(ethylene-vinyi acetate), or to polymers comprising unsaturated moieties, e.g., polybutadiene, polyisoprene, ethylene- propylene-(diene monomer) terpolymers and polystyrene and its copolymers. The trisaryl-1 ,3,5-triazines of the present invention may be used in widely varying amounts in such applications depending upon such things as the material to be stabilized and the particular application. However, when employed as a stabilizing additive for materials such as organic polymers, the trisaryl-1 ,3,5-triazines of the present invention are typically employed in amounts from about 0.01 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and most preferably from about 0.1 to about 5% by weight, based on the weight of the material to be stabilized. In screening applications such as sunscreening compositions, the thazines are utilized in the same relative amounts but based on the total weight of the screening agent. The novel stabilizers of the present invention may also be employed in a non- bondable capacity, for example, in the stabilization of thermoplastic polymers as set forth in the many of the previously incorporated references. Examples of preferred thermoplastic polymers are polyolefins and polymers comprising heteroatoms in the main chain. Preferred polymers are also thermoplastic polymers comprising nitrogen, oxygen and/or sulphur, especially nitrogen or oxygen, in the main chain. Also of interest are compositions in which the polymer is a polyolefin, for example polyethylene or polypropylene. Incorporation into the thermoplastic polymers can be carried out by addition of the triazine compounds and any further additives by the methods conventional in the art. The incorporation can expediently be made before or during shaping, for example by mixing the pulverulent components or by adding the stabilizer to the melt or solution of the polymer, or by applying the dissolved or dispersed compounds to the polymer, with or without subsequent evaporation of the solvent. Elastomers can also be stabilized as lattices. The novel mixtures can also be added to the polymers to be stabilized in the form of a masterbatch which comprises these compounds, for example, in a concentration of from about 2.5 to about 25%, preferably from about 5 to about 20% by weight of the polymer. The novel mixtures can expediently be incorporated into the polymeric material by any number of methods, including those conventionally employed in the art, including by, for example: a) as an emulsion or dispersion (for example to lattices or emulsion polymers); (b) as a dry mix during mixing of additional components or polymer mixtures; (c) by direct addition to the processing equipment (for example extruders, internal mixers, etc.); or (d) as a solution or melt. The stabilized polymer compositions obtained in this way can be converted into shaped articles, for example fibers, films, tapes, sheets, sandwich boards, containers, pipes and other profiles, by any number of conventional methods, for example hot pressing, spinning, extrusion, roto-molding or injection molding. Therefore, the present invention additionally relates to the use of the polymer composition according to the invention for the production of a shaped article.

The trisaryl-1 ,3,5-triazines of the present invention can also be employed in multilayer systems. In such systems, a polymer composition having from about 0.1 to about 20% by weight and preferably a relatively high content of novel stabilizer, for example, about 5- 15% by weight, is applied in a thin film (e.g., about 5 - 500 μm thick and, preferably, about 10 - 100 μm thick) to a shaped article made from a polymer containing little or no ultraviolet stabilizers. Such composition may be applied at the same time as the shaping of the base structure, for example by coextrusion in a manner analagous to that described in US4948666 (incorporated by reference herein for all purposes as if fully set forth). Alternatively, application can also be made to the ready-formed base structure, for example by lamination with a film or by coating with a solution. The outer layer or layers of the finished article have the function of a UV filter, which protects the interior of the article from UV light. The outer layer preferably contains about 0.1 to about 20%, preferably about 1 to about 15%, and most preferably about 2 to about 10% by weight of the outer layer composition, of at least one of the present trisaryl-1 ,3,5-triazine compounds of the present invention of the formulas (I), (II), or (III). The polymers stabilized in this way are notable for high weathering resistance, especially for high resistance to UV light. This enables them to retain their mechanical properties, and their color surface properties such as gloss and distinctness of image, for a long time even when used outside. Moreover, due to the bondable nature of the presently claimed triazine compounds, migration of these UV absorbers between the layers of the multi-layer coatings can, under the appropriate circumstances, be minimized. In another embodiment of the present invention, the novel mixtures comprising compounds of the formulas (I), (II), or (III) can be used as stabilizers for coatings, for example for paints such as disclosed in numerous of the previously incorporated references (see, e.g., US4619956, US4740542, US4826978, US4962142, US5106891 , US5198498, US5298067, US5322868, US5354794, US5369140, US5420204, US5461151 , US5476937, EP-0434608 and EP-A-0444323). Of particular interest are coatings and paints for the automobile industry. The invention therefore also relates to those compositions which are film-forming binders for coatings. Such novel coating compositions comprise about 0.01 to about 20%, preferably about 0.01 to about 10%, and more preferably about 0.02 to about 5% by weight of the binder of the coating composition of the trisaryl-1 ,3,5-triazines of the present invention. Multilayer systems are possible here as well (such as electrocoat/basecoat/clearcoat systems), where the concentration of the novel stabilizer in one or more of the layers, and typically the outer layer such as the clearcoat, can be relatively high, for example from about 0.01 to about 20%, preferably about 0.01 to about 10%, and more preferably about 0.02 to about 5% by weight of binder. The use of the novel stabilizer in coatings is accompanied by the additional advantage that it prevents delamination, i.e. the flaking-off of the coating from the substrate. This advantage is particularly important in the case of metallic substrates, including multilayer systems on metallic substrates, and particularly epoxy e-coated metallic substrates. The binder can in principle be any binder which is customary in industry, for example those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 368-426, VCH, Weinheim 1991 which is incorporated herein by reference. In general, it is a film-forming binder based on a thermoplastic or curable resin, predominantly on a curable resin. Examples of thermoplastic binders incude acrylics, polyesters, polyurethanes and PVC plastisols. Examples of curable binders include functional alkyd, acrylic, polyester, phenolic, melamine, epoxy and polyurethane resins and mixtures thereof. Such curable binders can be an ambient curable or a thermosetting binder. Further, in some systems it may be advantageous to add a curing catalyst to such systems. Suitable catalysts which accelerate curing of the binder are described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A18, p. 469, VCH Verlagsgeselischaft, Weinheim 1991 which is incorporated herein by reference. Preferred binders include those which comprise a functional acrylate resin and a crosslinking agent. A wide variety of binders may be employed in such coating systems. Examples of suitable coating compositions containing specific binders include but are not limited to: 1. paints based on ambient curable or thermosetting alkyd, acrylate, polyester, epoxy or melamine resins or mixtures of such resins, if desired with addition of a curing catalyst; 2. two-component polyurethane paints based on hydroxyl-containing acrylate, polyester or polyether resins and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates; 3. one-component polyurethane paints based on blocked isocyanates, isocyanurates or polyisocyanates which are deblocked during baking; 4. two-component paints based on (poly)ketimines and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates; 5. two-component paints based on (poly)ketimines and an unsaturated acrylate resin or a polyacetoacetate resin or a methacrylamidoglycolate methyl ester; 6. two-component paints based on carboxyl- or amino-containing polyacrylates and polyepoxides; 7. two-component paints based on acrylate resins containing anhydride groups and on a polyhydroxy or polyamino component; 8. two-component paints based on (poly)oxazolines and acrylate resins containing anhydride groups, or unsaturated acrylate resins, or aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates; 9. two-component paints based on unsaturated polyacrylates and polymalonates; 10. thermoplastic polyacrylate paints based on thermoplastic acrylate resins or externally crosslinking acrylate resins in combination with etherified melamine resins; 11. paint systems based on siloxane-modified or fluorine-modified acrylate resins. In addition to the binder and trisaryl-1 ,3,5-triazines of the present invention, the coating composition according to the invention preferably further comprise one or more additional ultraviolet light absorbers, including but not limited to those specifically listed above in section b. The additional UV absorbers may be, for example, another tris-aryl- 1 ,3,5-triazine, a 2-hydroxyphenyl-2H-benzotriazole, a 2-hydroxybenzophenone, an ester of an unsubstituted benzoic acid, an acrylate, an oxamide (oxanilide), or any combination of the above. Preferably, the additional UV absorber is a 2-hydroxyphenyl-2H-benzotriazole and the weight ratio of benzotriazole to triazine is 4:1 to 1 :4. More preferably, the weight ratio of benzotriazole to triazine is 2:1 to 1 :2. To achieve maximum light stability, it is of particular interest to add sterically hindered amines, examples of which are set out in the above-mentioned section b(vi). The invention therefore also relates to a coating composition which, in addition to the binder, the novel trisaryl-1 ,3,5-triazines and, optionally, additional UV absorbers, comprises a light stabilizer of the sterically hindered amine type. The sterically hindered amine is employed in an amount of about 0.01 to 5% by weight based on the weight of the solid binder, preferably about 0.02 to 2% by weight. One specific example of such a sterically hindered amine is a 2,2,6,6-tetramethyl piperazinone containing at least one group of the formula: in which G is, for example, hydrogen, hydroxyl, alkyl (such as methyl), alkoxy (such as methoxy) or acyl. More preferably the stabilizer is a 2,2,6,6-tetraalkylpiperidine derivative containing at least one group of the formula: in which G is, for example, hydrogen, hydroxyl, alkyl (such as methyl), alkoxy (such as methoxy) or acyl. Examples of tetraalkylpiperidine derivatives which can be used in combination with the present trisaryl-1 ,3,5-triazine compounds are given in US4314933, US4344876, US4426471 , US4426472, US4619956, US5004770, US5006577, US5064883, US5112890, US5124378, US5106891 , US5204473, US5461151 and EP-A-0434608 which (to the extent not already done so) are incorporated by reference herein for all purposes as if fully set forth. It is particularly expedient to employ the following tetraalkylpiperidine derivatives, as well as their N-alkyl, N-acyl, N-hydroxyl and N-alkoxy analogs (where not already included in the following list): bis(2,2,6,6-tetramethylpiperid-4-yl) succinate, bis(2,2,6,6-tetramethylpiperid-4-yl) sebacate, bis(1 ,2,2,6,6-pentamethylpiperid-4-yl) sebacate, di(1 ,2,2,6,6-pentamethylpiperid-4-yl) butyl-(3,5-di-tert-butyl-4-hydroxybenzyl)malonate, bis(1 -octyloxy-2,2,6,6-tetramethyipiperid-4-yl) sebacate, tetra(2,2,6,6-tetramethylpiperid-4- yl) butane-1 ,2,3,4-tetracarboxylate, tetra(1 ,2,2,6,6-pentamethylpiperid-4-yl) butane-1 ,2,3,4- tetracarboxylate, 2,2,4,4-tetramethyl-7-oxa-3,20-diaza-21 -oxo- dispiro[5.1.11.2]heneicosane, and 8-acetyl-3-dodecyl-1 ,3,8-triaza-7,7,9,9- tetramethylspiro[4.5]decane-2,4-dione. Commercially available examples of these and other tetraalkylpipieridine derviatives include SANDUVOR ® 3050, 3052, 3055, 3056, 3058, PR-31 and PR-32 (Clariant Corp.); TINUVIN® 079L, 123, 144, 292, 440L and 622LD (Ciba Specialty Chemicals); CHIMASORB® 119 (Ciba Specialty Chemicals); and CYAGARD® UV-3853, UV-500 and UV-516 (Cytec Industries Inc.). Apart from the binder, the trisaryl-1 ,3,5-triazine, and, if used, the additional ultraviolet light absorber or stabilizer, the coating composition can also comprise further components, examples being solvents, pigments, dyes, plasticizers, stabilizers, thixotropic agents, drying catalysts and/or leveling agents. Examples of possible components are those described in many of the previously incorporated references as well as Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 429-471 , VCH, Weinheim 1991 ; and Calbo, Leonard J., ed., Handbook of Coatings Additives, New York:Marcel Dekker (1987). Possible drying catalysts or curing catalysts are, for example, organometallic compounds, amines, amino-containing resins and/or phosphines. Examples of organometallic compounds are metal carboxylates, especially those of the metals Pb, Mn, Co, Zn, Zr or Cu, or metal chelates, especially those of the metal Al, Ti or Zr, or organometallic compounds such as organotin compounds, for example. Examples of metal carboxylates are the stearates of Pb, Mn or Zn, the octoates of Co, Zn or Cu, the naphthenates of Mn and Co or the corresponding linoleates, resinates or tallates. Examples of metal chelates are the aluminum, titanium or zirconium chelates of acetylacetone, ethyl acetylacetate, salicylaldehyde, salicylaldoxime, o- hydroxyacetophenone or ethyl trifluoroacetylacetate and the alkoxides of these metals. Examples of organotin compounds are dibutyltin oxide, dibutyltin dilaurate or dibutyltin dioctoate. Examples of amine drying or curing catalysts are, in particular, tertiary amines, for example tributylamine, triethanolamine, N-methyldiethanolamine, N-dimethylethanolamine, N-ethylmorpholine, N-methyimorpholine or diazabicyclooctane (triethylenediamine) and salts thereof. Further examples are quaternary ammonium salts, for example trimethylbenzylammonium chloride. Amino-containing resins are simultaneously binder and curing catalyst. Examples thereof are amino-containing acrylate copolymers. The curing catalyst used can also be a phosphine, for example triphenylphosphine. Another type of curing catalyst is a peroxide which can be used, for example, to cure a gel coating for a fibergalss article. The novel coating compositions can also be radiation-curable coating compositions. In this case, the binder essentially comprises monomeric or oligomeric compounds containing ethylenically unsaturated bonds, which after application are cured by actinic radiation, i.e. converted into a crosslinked, high molecular weight form. Where the system is UV-curing, it generally contains a photoinitiator as well. Corresponding systems are described in the above-mentioned publication Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pages 451-453. In radiation-curable coating compositions, the novel stabilizers can also be employed without the addition of sterically hindered amines. The novel coating compositions according to the invention can be applied to any desired substrates, for example to metal, wood, plastic, fibergalss or ceramic materials. The coating compositions can be pigmented mono-coats or multi-layer (primer/basecoat/clearcoat) systems typical of automotive finishes. In the latter case, the novel coating composition can be used for either the base coat, or clear coat, or for both layers. If the topcoat of an automotive finish comprises two layers, of which the lower layer is pigmented and the upper layer is not pigmented, the novel coating composition can be used for either the upper or the lower layer or for both layers, but preferably for the upper topcoat layer. The novel coating compositions can be applied to the substrates by the customary methods, for example by brushing, spraying, pouring, dipping or electrophoresis; see also Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 491-500. Depending on the binder system, the coatings can be cured at room temperature or by heating. Thermosettig coatings are preferably cured at 50 - 150°C and, in the case of powder coatings, even at higher temperatures. The coatings obtained in accordance with the invention have excellent resistance to the damaging effects of light, oxygen and heat; particular mention should be made of the good light stability and weathering resistance of the coatings thus obtained, for example paints. The invention therefore also relates to a coating, in particular a paint, which has been stabilized against the damaging effects of light, oxygen and heat by a content of the compound of the formula (I), (II) or (III) according to the invention. The paint can be a pigmented mono-coat which comprises a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixture thereof. The paint may also be a composition which comprises a primer in adhesion to a metal or plastic substrate; a pigmented basecoat that is in adhesion to the primer and which comprises a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixture thereof; and a clear coat that is in adhesion to the base coat and which comprises a film-forming binder and optionally a transparent pigment. One especially preferred use is a paint which is a clear topcoat for automobile original equipment manufacture (OEM) and/or refinish applications. The invention furthermore relates to a process for stabilizing a coating based on polymers against damage by light, oxygen and/or heat, which comprises mixing with the coating composition a mixture comprising a trisaryl-1 ,3,5-triazine of the present invention, and to the use of mixtures comprising such trisaryl-1 ,3,5-triazine compounds in coating compositions as stabilizers against damage by light, oxygen and/or heat. The coating compositions can comprise an organic solvent or solvent mixture in which the binder is soluble. The coating composition can otherwise be an aqueous solution or dispersion. The vehicle can also be a mixture of organic solvent and water. The coating composition maybe a high-solids paint or can be solvent-free (e.g. a powder coating material). The pigments can be inorganic, organic or metallic pigments. The novel coating compositions preferably contain no pigments and are used as a clearcoat. Likewise preferred is the use of the coating composition as a topcoat for applications in the automobile industry, especially as a pigmented or unpigmented topcoat of the paint finish. Its use for underlying coats, however, is also possible. The triazines of this invention may be applied topically by polishing a surface with a composition comprising the triazines and an inert carrier such as solvent, petroleum jelly, silicone oil in water emulsions, or automotive paint wax, e.g. Carnauba wax. These topical treatment compositions may be used to stabilize coating films, fabrics, leather, vinyl and other plastics and wood. Preference is also given to the use of the novel trisaryl-1 ,3,5-triazine compounds in photographic materials as stabilizer against damage by light, especially by UV light. The invention therefore also relates to a photographic material comprising the present trisaryl- 1 ,3,5-triazine compounds. The compounds according to the invention can be used for photosensitive materials of all kinds. For example, they can be employed for color paper, color reversal paper, direct-positive color material, color negative film, color positive film, color reversal film and other materials. They are preferably used, inter alia, for photosensitive color material which comprises a reversal substrate or which forms positives. Furthermore, the novel compounds can be combined with other UV absorbers, especially those which are dispersible in aqueous gelatin, for example with hydroxyphenylbenzotriazoles (cf. for example US4853471 , US4973702, US4921966 and US4973701), benzophenones, oxanilides, cyanoacrylates, salicylates, or acrylonitriles or thiazolines. In this context it is advantageous to employ these further, oil-dissolved UV absorbers in the photographic material in layers other than those comprising the novel UV absorbers. In particular, it is possible successfully to stabilize photographic materials similar to those described in US4518686. The invention therefore additionally relates to a photographic material comprising, on support, a blue-sensitive, a green-sensitive and/or a red-sensitive silver-halide emulsion layer and, if desired, a protective layer, with a layer comprising a UV absorber being arranged above the uppermost silver-halide emulsion layer, wherein the UV absorber is a trisaryl-1 ,3,5-triazine compound of the present invention. Preference is additionally given to photographic materials which have a layer comprising a compound of the formula (I), (II) or (III) above the uppermost silver-halide emulsion layer and/or between the green- and red-sensitive silver-halide emulsion layers. Furthermore, it may be advantageous for all or some of the said layers which can comprise a UV absorber to have a UV absorber mixture and/or a further UV absorber which is dispersible in aqueous gelatin, but a compound of the formula (I), (II) or (III) must be present at least in one layer. The novel material preferably has gelatin interlayers between the silver-halide emulsion layers. Preference is given to photographic materials in which the silver halide in the blue- sensitive, green-sensitive and/or red-sensitive layer is silver chloride bromide comprising at least 90 mol % of silver chloride. The compounds of the formula (I), (II) or (III) which are used in accordance with the invention can be incorporated, alone or together with the color coupler and, if used, further additives, into the color photographic materials by dissolving the compounds beforehand in high-boiling organic solvents. It is preferred to use solvents which boil at higher than 160°C. Typical examples of such solvents are the esters of phthalic acid, phosphoric acid, citric acid, benzoic acid or of fatty acids and also alkylamides and phenols. Preferred color couplers for use in the compositions of the invention, examples of such compounds, further additives such as color cast inhibitors, DIR couplers and further light stabilizers, such as UV absorbers, phenols, phosphorus (III) compounds, organometallic complexes, hydroquinones and hydroquinone ethers, and more precise details on the structure of various photographic materials, can be found, for example, in the publications EP-A-0531258 and EP-A-0520938 and in the literature cited therein. The trisaryl-1 ,3,5-triazine compounds of the formula (I), (II) or (III) are suitable for the photochemical stabilization of undyed, dyed or printed fiber materials comprising for example, silk, leather, wool, polyamide or polyurethanes and especially cellulose- containing fiber materials of all kinds. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen, jute and hemp and also viscose staple fiber and regenerated cellulose. Preferred textile fiber materials are those of cotton. The triazine compounds of the present invention are also suitable for the photochemical stabilization of hydroxyl-containing fibers in blend fabrics, for example blends of cotton with polyester fibers or polyamide fibers. A further preferred area of application relates to the blocking or reduction of the UV radiation which passes through the above-mentioned textile materials (UV cutting) and the heightened sun protection which textile materials finished with a novel compound offer to the human skin. To this end, one or a number of different compounds of the formula (I), (II) or (III) are applied to the textile fiber material by one of the customary dyeing methods, advantageously in a quantity of 0.01 to 5% by weight, preferably 0.1 to 3% by weight and, in particular, from 0.25 to 2% by weight, based on the weight of the fiber material. The present trisaryl-1 ,3,5-triazine compounds can be applied to the fiber material in various ways and fixed on the fiber, especially in the form of aqueous dispersions or printing pastes. The textile fiber materials finished with the novel compounds of the formula (I), (II) or (III) possess improved protection against photochemical breakdown of the fiber and yellowing phenomena and, in the case of dyed fibre material, are of enhanced (hot) light fastness. Particular emphasis should be drawn to the greatly improved photoprotective effect of the treated textile fiber material and, in particular, the good protective effect with respect to short-wave UV-B rays. This is manifested by the fact that the textile fiber material finished with a trisaryl-1 ,3,5-triazine compound has, relative to untreated fabric, a greatly increased sun protection factor (SPF). The sun protection factor is defined as the quotient of the dose of UV radiation which damages protected skin to that which damages unprotected skin. Accordingly, a sun protection factor is also a measure of the extent to which untreated fiber materials and fiber materials treated with a novel compound of the formula (I), (II) or (III) are permeable to UV radiation. The determination of the sun protection factor of textile fiber materials is explained, for example, in WO94/04515 or in J. Soc. Cosmet. Chem. 40, 127-133 (1989) and can be carried out analogously thereto. Yet another use of the UV absorbers according to the invention is in the stabilization of intra-ocular and contact lenses. The UV absorbers according to the invention are suitable, furthermore, as photoprotective agents in cosmetic preparations. The invention additionally relates, therefore, to a cosmetic preparation comprising at least one such trisaryl-1 ,3,5-triazine compound and cosmetically acceptable carriers or auxiliaries. The novel cosmetic composition contains from 0.1 to 15% by weight, preferably from 0.5 to 10% by weight, based on the overall weight of the composition, of a trisaryl-1 ,3,5- triazine UV absorber and a cosmetically acceptable auxiliary. The cosmetic composition can be prepared by physically mixing the novel UV absorber with the auxiliary by means of customary methods, for example by simply stirring together the two materials. The cosmetic preparation according to the invention can be formulated as a water-in- oil or oil-in-water emulsion, as an oil-in-oil alcohol lotion, as a vesicular dispersion of an ionic or nonionic amphiphilic lipid, as a gel, solid stick or as an aerosol formulation. As a water-in-oil or oil-in-water emulsion, the cosmetically acceptable auxiliary preferably contains from 5 to 50% of an oily phase, from 5 to 20% of an emulsifier and from 30 to 90% water. The oil phase mentioned can comprise any oil which is suitable for cosmetic formulations, for example one or more hydrocarbon oils, a wax, a natural oil, a silicone oil, a fatty acid ester or a fatty alcohol. Preferred mono- or polyols are ethanol, isopropanol, propylene glycol, hexylene glycol, glycerol and sorbitol. For the cosmetic formulations according to the invention it is possible to use any conventionally employed emulsifier, for example one or more ethoxylated esters of naturally occurring derivatives, for example polyethoxylated esters of hydrogenated castor oil; or a silicone oil emulsifier such as silicone polyol; an unmodified or ethoxylated fatty acid soap; an ethoxylated fatty alcohol; an unmodified or ethoxylated sorbitan ester; an ethoxylated fatty acid; or an ethoxylated glyceride. The cosmetic formulation can also comprise further components, for example emollients, emulsion stabilizers, skin moisteners, tanning accelerators, thickeners such as xanthan, moisture retention agents such as glycerol, preservatives, or fragrances and colorants. The novel cosmetic formulations are notable for good protection of human skin against the damaging effect of sunlight while at the same time providing for reliable tanning of the skin. The invention will now be illustrated by the following examples. The examples are not intended to be limiting of the scope of the present invention. In conjunction with the general and detailed descriptions above, the examples provide further understanding of the present invention. EXAMPLES Preparation of Compound A 2-[2-hydroxy-4-(acetoacetyloxyethyloxy)phenyl]-4,6-bis(2,4-dimethylphenyl)-1 ,3,5- triazine (Compound A) was synthesized using the following reaction scheme: The following were added, from first to last, to a 2 neck round bottom flask equipped with a magnetic stirring bar, a reflux condenser, an argon inlet and a glass stopper: 4.41 g of 2-[2-hydroxy-4-(hydroxyethyloxy)phenyl]-4,6-bis(2,4-dimethylphenyl)-1 ,3,5- triazine, 5.0 ml of ethyl acetoacetate, 20.0 ml of xylene, and 60 mg of dimethylaminopyridine ("DMAP") as catalyst. The reaction mixture was heated to reflux for 16 hours, then allowed to cool to room temperature and concentrated under reduced pressure to remove volatiles. The residue was purified by silica gel column chromatography to give 4.46 g of a product determined to be Compound A by 1 H NMR, 13 C NMR and mass spectroscopy. Preparation of Compound B 2-[2-hydroxy-4-(acetoacetyloxyhexyloxy)phenyl]-4,6-bis(2,4-dimethylphenyl)-1 ,3,5- triazine (Compound A) was synthesized using the following reaction scheme: The following were added, from first to last, to a 2 neck round bottom flask equipped with a magnetic stirring bar, a reflux condenser, an argon inlet and a glass stopper: 1.5 g of 2-[2-hydroxy-4-(hydroxyhexyloxy)phenyl]-4,6-bis(2,4-dimethylphenyl)-1 ,3,5- triazine, 1.5 ml of ethyl acetoacetate, 10 ml of xylene, and 18 mg of DMAP as catalyst. The reaction mixture was heated to reflux for 6 hours, then allowed to cool to room temperature and concentrated under reduced pressure to remove volatiles. The residue was purified by silica gel column chromatography to give 1.55 g of a product determined to be Compound B by 1 H NMR, 13 C NMR and mass spectroscopy. Preparation of Compound C 2-[2-hydroxy-4-((N-ethyl-N-acetoacetyloxyethyl)methanamidooxy)phenyl]-4,6-bis(2,4- dimethylphenyl)-1 ,3,5-triazine (Compound C) was synthesized using the following reaction scheme: The following were added, from first to last, to a 2 neck round bottom flask equipped with a magnetic stirring bar, a reflux condenser, an argon inlet and a glass stopper: 20 g of 2-[2-hydroxy-4-((N-ethyl-N-hydroxyethyl)methanamidooxy)phenyl]-4,6-bis(2,4- dimethylphenyl)-1 ,3,5-triazine, 19.8 ml of ethyl acetoacetate, 150 ml of xylene, and 230 mg of DMAP as catalyst. The reaction mixture was heated to reflux for 3 hours, then allowed to cool to room temperature and concentrated under reduced pressure to remove volatiles. The residue was purified by silica gel column chromatography to give 24.67 g of a product determined to be Compound A by 1 H NMR, 13 C NMR and mass spectroscopy. Example 1 - Bondability of Compound A A mixture of 780 mg of CYMEL® 303 (a highly methylated melamine-formaldehyde resin of Cytec Industries Inc., West Paterson, NJ), 1.05 g of Compound A, 40 mg p-toluene sulfonic acid (acid catalyst), and toluene was heated at reflux for 4 hours. A thin layer chromatography analysis of the reaction mixture revealed that Compound A had completely reacted with the CYMEL® 303. Accordingly, one of ordinary skill in the art would recognize that the acetoacetate functionalized trisaryl-1 ,3,5-triazine is a bondable material. Example 2: Bonding of Compound B to Acrylic/Melamine Resin Matrix Compound B was investigated to determine whether it forms a chemical bond with the acrylic/melamine resin matrix during cure. For this purpose, it was added to a clearcoat formulation and coated onto a plastic substrate, as described below. Non-bondable UV absorbers readily migrate from clearcoats into plastic substrates upon curing the coating. An absorber which bonds to the matrix should not migrate into the plastic substrate to any significant extent. The acrylic/melamine resin formulation utilized was as follows: 40.6 g JONCRYL® 510 acrylic resin (S.C. Johnson & Son, Inc., Racine, Wl) 17.5 g CYMEL® 303 crosslinker (Cytec Industries Inc., West Paterson, NJ) 0.52 g CYCAT® 4040 catalyst (Cytec Industries Inc., West Paterson, NJ) 10.0 g n-Butanol 0.50 g DC 57 flow control agent 8.0 g Xylene. To this formulation was added 3% of Compound B based on total resin solids. The resulting coating was drawn onto plastic RIM substrates (Dow SPECTRIM® 50) using a #58 cator rod and cured for 30 minutes at 135°C. After cure, the coating and part of the substrate were microtomed into 10 μm thick slices parallel to the coating surface. The microtome was a Reichert-Jung Polycut E instrument. Each microtomed slice was mounted between two microscope slides and its UV absorption spectrum measured using a Perkin-Elmer Lambda 2 spectrophotometer. The absorbance per micrometer sample thickness was determined at the prominent 340 nm absorption band intrinsic to this UVA. The results of the UV analysis were plotted as function of depth. The original coating surface in contact with the atmosphere is located at 0 μm. The coating/substrate interface was at about 70 μm below the surface. The total microtomed depth was about 130 μm. The plotted curve showed a steep drop of the absorbance near the coating/substrate interface, indicating that most of the Compound B molecules remained in the coating, and only minor amounts migrated through the interface into the plastic substrate. By measuring the area under the curve, the quantity of Compound B remaining in the coatings and the fraction that migrated into the substrates were estimated. The result is that about 85% of the added Compound B remained in the coating, with only about 15% migrating into the substrate. For comparison, CYAGARD® UV1164L (a non-bondable triazine UV absorber available from Cytec Industries Inc.) was found to migrate into RIM substrates. Under identical experimental conditions (30 minutes cure at 135°C), 63% of the added non- bondable triazine UVA migrated into the substrate and only 37% was left in the coating. Example 3: Bonding of Compound B to Polyurethane Resin Matrix Bonding of Compound B in a solvent based polyurethane coating was confirmed by a second experiment. The solvent based polyurethane coating used had the following formula: 103 g JONCRYL® CDX-588 acrylic resin (68% solids) (S.C. Johnson & Son, Inc., Racine, Wl) 33 g DESMODUR N-3390 crosslinker (90% solids) (Bayer Corp., Pittsburgh, PA) 59 g 1 :1 :1 xylene:MAK:PM Acetate solvent mix 5 g T-12 catalyst. Compound B was added to this formulation at the 2% level. The coating was drawn onto a block copoly(ester-ether) plastic substrate (HYTREL® DYM 100, available from E.I. duPont de Nemours and Company) used for automotive applications, with a #58 cator rod. After cure at 120°C for 30 minutes, the coating and part of the substrate were microtomed and the microtomed slices extracted using supercritical fluid extraction. The extracts were analyzed for Compound B using HPLC. No Compound A was detected in the slices cut from the substrate, and only 0.48% was found in the coating. This indicates that Compound B was chemically bonded to the coating resin matrix. Example 4: Accelerated Weathering Testing of Clear Coatings Formation of Clear Coatings Compounds A and B were formulated in clear coatings which were applied to panels for accelerated weathering testing as follows. Compound A or B (2% based on total resin solids) and/or SANDUVOR® S-3055 HALS-type stabilizer (1% based on total resin solids) were predissolved in the solvent mixture (to a 5-10% solids level) and added to the clear acrylic urethane formulation given in Table 1 below. Components I and II were mixed just before use. Cold roll steel panels measuring 4" x 12" and precoated with an electro-coat primer ED5050A and a white polyester acrylic melamine base-coat #542AB839, obtained from ACT Laboratories, Inc. (Hillsdale, Ml) were coated with the clear coating formulations of Table 1. The draw-down technique, using WC-60 WireCators™ (Leneta Co., Ho-Ho- Kus, NJ), was used to apply the clear coat to the pre-coated panels. The clear coats were allowed to flash for 10 min at ambient temperature and cured for 30 min at 135°C. Table 1.
