Description: PHOTOSTABLE. SILYLATED BENZOTRIAZOLE UV ABSORBERS AND COMPOSITIONS STABILIZED THEREWITH The instant invention pertains to photostable, silylated benzotriazole UV absorbers and compositions stabilized therewith. These benzotriazole compounds are novel and exhibit enhanced durability due to the incorporation of electron withdrawing moieties at the 5- position of the benzo ring. The polymer compositions containing said benzotriazoles are advantageously stabilized, especially high performance coatings such as organopoly- siloxanes. The instant compounds are red-shifted and show increased absorption in the 350- 400 nm region of the UV spectrum. United States Patent No. 4,859,759 describes in the most generic manner siloxane compounds containing at least one benzotriazole and one hindered amine substituent covalently coupled to a silicon atom. This reference does not supply any specific exemplification of such structures. The particular structures of the instant invention are neither disclosed nor suggested by this reference. United States Patent Nos. 5,707,690 and 5,756,793 disclose the use of silylated benzophenones for the protective coatings for wood. EP 675,108 B1 describes thioether substituted benzophenone UV absorbers which may also contain silylated substituents. United States Patent Nos. 5,185,445 and 5,837,792 describe polysiloxane light stabilizers which contain pendant hydroxyphenyl-diaryl-s-triazine moieties. United States Patent Nos. 5,219,905; 5,321 ,066; 5,418,267; 5,463,058 and 5,578,665 disclose hindered amines containing siloxane and other silyl moieties as stabilizers. United States Patent Nos. 5,391 ,795 and 5,679,820 describe the preparation and use of silylated benzophenone UV absorbers. United States Patent No. 5,391 ,795 compares these silylated benzophenone UV absorbers with one example of a silylated benzotriazole UV absorber which is 2-{2-hydroxy-5-[3-(3-triethoxysilyl)propylcarbamoyloxy]propylphenyl}- 2H-benzotriazole. This silylated benzotriazole compound contains neither a bulky substituent ortho to the hydroxy group in the phenyl ring nor an electron withdrawing group at the 5- position of the benzo ring. Both of these two substitution patterns are shown to be particulary efficacious in enhancing long term photostability of the benzotriazoles. The electron withdrawing group at the 5-position^of the benzo ring allows for the red-shifting of the UV spectrum of the benzotriazoles. United States Patent No. 4,373,061 teaches the use of silicone coatings for unprimed plastic substrates and coated articles. The silicone coating contains a UV absorbing organic group attached to silicon by carbon-silicon bonds. The UV absorber is a silylated hydroxy- benzophenone. United States Patent No. 4,322,455 describes a process for producing an ultraviolet radiation stabilized polymeric article which contains on the surface of said article a UV absorbing composition. The UV absorber may be generically any of the known types of compounds such as benzophenones, benzotriazole, cyanoacrylates or benzylidene malonates. The only benzotriazole disclosed is 2-(2-hydroxy-5-tert-octylphenyl)-2H- benzotriazole. U.S. Pat. No. 6,166,218, demonstrates the value of having such substitution at the 3- position of the phenyl ring by a bulky group and at the 5-position of the benzo ring by an electron withdrawing moiety. All the instant compounds have an electron withdrawing moiety at the 5-position of the benzo ring. When there is a bulky substituent at the 3-position of the phenyl ring, particularly an α-cumyl group, the photostability of the benzotriazole is particularly enhanced. j The first object of this invention is to provide for new monomeric benzotriazole UV absorbers which contain silicon moieties. Another object of this invention is to provide silicone/siloxane hardcoat or softcoat resin compositions containing said benzotriazole UV absorbers which can be added to or copolymerized into such hardcoat or softcoat resins. Still another object of the invention is to provide for articles which contain the silicone/siloxane hardcoat or softcoat composition as a screening layer in a laminate composition, such as over polycarbonate. Another object of the 1 invention is to provide automotive coating compositions in which the instant compounds are melamine/siloxane crosslinked structures. Still another object of the invention is to provide for polymer compositions where the instant compounds are used in conjunction with silylated hindered amines including inter alia N-hydrocarbyloxy and N-hydroxyalkyloxy substituted hindered amines. Still another object of the invention is to provide for silicone/siloxane hardcoat or softcoat compositions containing post-added other advanced benzotriazoles which do not contain silicon moieties and with or without the concomitant presence of hindered amines, N- hydrocarbyloxy- or N-hydroxyalkyloxy-substituted hindered amines.

More preferred is a composition wherein the polymer, is a polyolefϊn or polycarbonate. Most especially, the polymer is a siloxane coating as a screening layer over polycarbonate. In another preferred embodiment of the instant invention, the organic material is a resin selected from the group consisting of a thermoset acrylic melamine resin, an acrylic urethane resin, an epoxy carboxy resin, a silane modified acrylic melamine, an acrylic resin with carbamate pendant groups crosslinked with melamine or an acrylic polyol resin crosslinked with melamine containing carbamate groups. Such automotive coatings are described in WO 92/20726; WO 92/05225 and by H. Furakawa et al., Progress in Organic Coatings, 24, 81-99 (1994) which describe the curing and properties of acrylosilane coatings. Most preferably, the resin is a thermoset acrylic melamine resin or an acrylic urethane resin. In another preferred embodiment of the invention the organic material of component (a) is a acrylosilane coating useful in organosilicone hardcoats or softcoats for automotive applications such as GENIVA (DuPont) coatings or for multilayered compositions. In yet another preferred embodiment of the instant invention, the organic material is a recording material. The recording materials according to the invention are suitable for pressure-sensitive copying systems, photocopying systems using microcapsules, heat-sensitive copying systems, photographic materials and ink jet printing. The recording materials according to the invention are distinguished by an unexpected improvement in quality, especially with regard to the fastness to light. The recording materials according to the invention have the construction known for the particular use. They consist of a customary carrier, for example, paper or plastic film, which has been coated with one or more layers. Depending on the type of material, these layers contain the appropriate necessary components, in the case of photographic materials, for example, silver halide emulsions, dye couplers, dyes and the like. Material particularly suitable for ink jet printing has a layer particularly absorptive for ink on a customary carrier. Uneoated paper can also be employed for ink jet printing. In this case the paper acts at the same time as the carrier material and as the ink-absorbent layer. Suitable material for ink jet printing is, for example, described in United States Patent No. 5,073,448 which is incorporated herein by reference. The recording material can also be transparent as, for example, in the case of projection films. The compounds of formula I or II can be incorporated into the carder material as early as the production of the latter, in the production of paper, for example, being added to the paper pulp. A second method of application is to spray the carder material with an aqueous solution of compounds of formula I or II or to add the compounds to the coating composition. Coating compositions intended for transparent recording materials suitable for projection cannot contain any particles which scatter light, such as pigments and fillers. The dye-binding coating composition can contain a number of other additives, for example, antioxidants, light stabilizers (including also UV absorbers which do not fall under the scope of the UV absorbers of this invention), viscosity improvers, fluorescent brighteners, biocides and/or antistatic agents. i The coating composition is usually prepared as follows: the water-soluble components, for example, the binder, are dissolved in water and stirred together; the solid components, for example, fillers and other additives already described, are dispersed in this aqueous medium; and disperison is advantageously carried out by means of devices, for example, ultrasonic systems, turbine stirrers, homogenizers, colloid mills, bead mills, sand mills, high-speed stirrers and the like. The compounds of formula I or II can be easily incorporated into the coating composition. The recording material according to this invention preferably contains 1 to 5000 mg/m 2 , in particular 50-1200 mg/m 2 , of a compound of formula I. As already mentioned, the recording materials according to the invention embrace a wide field. The compounds of formula I or II can, for example, be employed in pressure- sensitive copying systems. They can be introduced either into the paper in order to protect the microencapsulated dye precursors there from light, or into the binder of the developer layer in order to protect the dyes formed there. Photocopying systems using light-sensitive microcapsules which are developed by means of pressure are described in United States Patent Nos. 4,416,966; 4,483,912; 4,352,200; 4,535,050; 4,535,463; 4,551,407; 4,562,137 and 4,608,330; and also in EP-A 139,479; EP-A 162,664; EP-A 164,931; EP-A 237,024; EP-A 237,025 and EP-A 260,129. In all these systems, the compounds can be put into the dye-receiving layer. The compounds can, however, also be put into the donor layer in order to protect the color formers from light. Photographic materials which can be stabilized are photographic dyes and layers containing such dyes or precursors thereof, for example, photographic paper and films. Suitable materials are, for example, described in United States Patent No. 5,364,749 which is incorporated herein by reference. The compounds of formula I or II act here as a UV filter against electrostatic flashes. In color photographic materials, couplers and dyes are also protected against photochemical decomposition. The instant compounds can be used for all types of color photographic materials. 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 the like. They are preferably used inter alia for photographic color material which contains a reversal substrate or form positives. Color-photographic recording materials usually contain, on a support, a blue-sensitive and/or a green-sensitive and/or a red-sensitive silver halide emulsion layer and, if desired, a protection layer, with the instant compounds being, preferably, either in the green-sensitive or the red-sensitive layer or in a layer between the green-sensitive and the red-sensitive layer or in a layer on top of the silver halide emulsion layers. The compounds of formula I or II can also be employed in recording materials based on the principles of photopolymerization, photoplasticization or the rupture of microcapsules, or in cases where heat-sensitive and light-sensitive diazonium salts, leuko dyes having an oxidizing agent or dye lactones having Lewis acids are used. Furthermore, the instant compounds can be employed in recording materials for dye diffusion transfer printing, thermal wax transfer printing and non-matrix printing and for use with electrostatic, electrographic, electrophoretic, magnetographic and laser-electrophotographic printers and pen-plotters. Of the above, recording materials for dye diffusion transfer printing are preferred, for example, as described in EP-A 507,734. The instant compounds can also be employed in inks, preferably for ink jet printing, for example, as described in United States Patent No. 5,098,477 which is incorporated herein by reference. The compounds of this invention exhibit superior hydrolytic stability, handling and storage stability as well as good resistance to extractability when present in a stabilized composition. The methodology to make the instant compounds is described in the prior art. The intermediates needed to make the instant compounds are largely items of commerce. ln general, the compounds of the present invention are employed in from about 0.01 to about 5% by weight of the stabilized composition, although this will vary with the particular substrate and application. An advantageous range is from about 0.05 to about 3%, and especially 0.05 to about 1%. However, some high performance films or in UV absorbing layers of laminates such as those produced by coextrusion may contain from 5-15% by weight of the instant compounds. Concentrations of 5-10% by weight are typical in certain coextrusion applications. The stabilizers of the instant invention may readily be incorporated into the organic polymers by conventional techniques, at any convenient stage prior to the manufacture of shaped articles therefrom. For example, the stabilizer may be mixed with the polymer in dry powder form, or a suspension or emulsion of the stabilizer may be mixed with a solution, suspension, or emulsion of the polymer. The resulting stabilized polymer compositions of the invention may optionally also contain from about 0.01 to about 5%, preferably from about r 0.025 to about 2%, and especially from about 0.1 to about 1% by weight of various — <~ - i conventional additives, such as the materials listed below, or mixtures thereof.

The alkyd resin lacquers which can be stabilized against the action of light and moisture in accordance with the instant invention are the conventional stoving lacquers which are used in particular for coating automobiles (automobile finishing lacquers), for example lacquers based on alkyd/melamine resins and alkyd/acrylic/melamine resins (see H. Wagner and H. F. Sarx, "Lackkunstharze" (1977), pages 99-123). Other crosslinking agents include glycouril resins, blocked isocyanates or epoxy resins. ~ — The lacquers stabilized in accordance with the invention are suitable both for metal finish coatings and solid shade finishes, especially in the case of retouching finishes, as well as various coil coating applications. The lacquers stabilized in accordance with the invention are preferably applied in the conventional manner by two methods, either by the single-coat method or by the two-coat method. In the latter method, the pigment-containing base coat is applied first and then a covering coat of clear lacquer over it. It is also to be noted that the compounds of the present invention are applicable for use in non-acid catalyzed thermoset resins such as epoxy, epoxy-polyester, vinyl, alkyd, acrylic and polyester resins, optionally modified with silicon, isocyanates or isocyanurates. The epoxy and epoxy-polyester resins are crosslinked with conventional crosslinkers such as acids, acid anhydrides, amines and the like. Correspondingly, the epoxide may be utilized as the crosslinking agent for various acrylic or polyester resin systems that have been modified by the presence of reactive groups on the backbone structure. When used in two-coat finishes, the compounds of the instant invention can be incorporated in the clear coat or both in the clear coat and in the pigmented base coat. When water-soluble, water miscible or water dispersible coating are desired ammonium salts of acid groups present in the resin are formed. Powder coating composition can be prepared by reacting glycidyl methacrylate with selected alcohol components. The instant benzotriazoles are made by conventional methods for preparing such compounds. The usual procedure involves the diazotization of a substituted o-nitroaniline followed by coupling the resultant diazonium salt with a substituted phenol and reduction of the azobenzene intermediate to the corresponding desired benzotriazole. The starting materials for these benzotriazoles are largely items of commerce or can be prepared by normal methods of organic synthesis. While the instant benzotriazoles with their enhanced durability are particularly suited for automotive coating applications, it is contemplated that they will also be especially useful in other applications where their enhanced durability is required such as in solar films and the like. The following examples are meant for illustrative purposes only. Example 1 5-Trifluoromethyl-2-(2-hydroxy-3-α-cumyl-5-tert-octylphenyl)-2H-benzotriazole a.

Reduction of the monoazo adduct A 1000 ml flask is charged with 20 g of sodium hydroxide, 40 ml of water, 42.1 g of the monoazo adduct prepared in part b. and 400 ml of ethanol. The mixture is warmed to 80°C and 27 g of formamidine sulfinic acid is added in portions with stirring. After 1.5 hours, the solution is cooled to room temperature and 100 ml of water are added. The pH is adjusted to pH 7 with concentrated hydrochloric acid. The ethanol is removed under vacuum and the water layer is extracted with methylene chloride. The solvent is then evaporated in vacuo and the residue is purified by chromatography (silica gel, heptane:tolunen 9:1) and crystallized from ethanol.

Examples 43-61 For Examples 43-46, these materials are prepared by a method analogous to the method of Example 5b of Unites States Patent No. 5,185,445 where the appropriate substituted benzotriazole is dissolved in toluene and is heated to 100°C with the hydroxy- substituted alkyl-silane or alkyl-siloxane in the presence of dibutyltin oxide for form the title compound. For Examples 47-48, these materials are prepared where the appropriate substituted benzotriazole is added to the reaction flask alone with the amino-substituted alkyl-silane or alkyl-siloxane and heated to 120°C. A slight vacuum is applied to facilitate removal of the methanol by-product to give the title compound. For Examples 49-52, the compounds are made by a method analogous to that of Example 6 of United States Patent No. 5,185,445 where a suspension of the appropriate benzotriazole starting material and 3-chloropropyl diethoxymethylsilane or related silane and potassium carbonate in anhydrous N,N-dimethylacetamide is heated to 100°C to yield the desired compounds. For Example 53, the appropriate intermediate benzotriazole is made by the procedure of Example 10. The intermediate is then hydrosilylated with diethoxymethylsilane using the experimental conditions of Example 4 to give the desired compound. The compounds of Examples 54-58 are prepared in several steps. The first intermediate benzotriazole is made by the method of Example 1 , but instead of using 2-α- cumyl-4-tert-octylphenol, the Michael adduct of resorcinol and methyl acrylate is used to give the desired compound. The second intermediate is then made by reacting the first intermediate benzotriazole with α-methylstyrene in the presence of p-toluenesulfonic acid. The next intermediate compound is prepared by reacting the second intermediate in a manner analogous to Example 30 of British 2,319,035A. The next intermediate is made by reacting the last intermediate benzotriazole with allyl alcohol in the presence of toluene solvent. Finally, the allyl substituted benzotriazole is reacted with diethoxymethylsilane using the conditions of Example 4. The compounds of Examples 59-62 are also prepared in several steps. The first intermediate is made by a method analogous to that of Example 3. In the next step this intermediate benzotriazole is hydroboration conditions as described by Brown in "Boranes in Organic Chemistry", Cornell University Press, Ithaca, NY 1972; and by J. March in "Advanced Organic Chemistry", 2nd Edition, McGraw-Hill, New York, 1977, page 718. This intermediate is reacted by the procedure of Example 10 by reacting the 2-(3-hydroxypropyl) substituted benzotriazole with allyl isocyanate. The title compound is prepared by the allyl urethane intermediate by reaction with diethoxymethylsilane according to the method of Example 4. Following the general methods described above, compounds of formula (IV) or (V) are prepared. > Εx jG.,_ _G_ 2 J≡ L T, / T A _Bι- -B2 43 H CF 3 Cu (CH 2 ) 2 /(CH 2 ) 3 -O- 3 Me Et 44 H CF 3 Cu (CH 2 ) 2 /(CH 2 ) 3 -O- 2 Me Et 45 H CF 3 Cu (CH 2 ) 2 /(CH 2 ) 3 -O- 1 Me Et 46 H CF 3 Cu (CH 2 ) 2 /(CH 2 ) 3 -O- 0 Me Et 47 H CF 3 tBu (CH 2 ) 2 /(CH 2 ) 4 -NH- 1 Me Me 48 Cl Cl tBu (CH 2 ) 2 /(CH 2 ) 3 -NH- 2 Me Et *ln the compounds of Examples 43-58, tBu is tert-butyl, Cu is α-cumyl, Et is ethyl and Me is methyl.

Using the Mannich base type conditions as outlined in copending application Serial No. 09/234,880 at Examples 34-35, the Mannich base of 2-(2-hydroxy-5-methylphenyl)-2H- benzotriazole is reacted with methyl 3-(5-trifluoromethyl-2H-benzotriazol-2-yl)-4-hydroxy- hydrocinnamate to form a ester substituted bis-benzotriazole intermediate. This ester intermediate product is reduced with lithium aluminum hydride to form the corresponding alcohol substituted benzotriazole according to the procedure of Example 19 of United States Patent No. 5,280,124. The hydroxyalkyl intermediate form is transformed into the corresponding alkene by refluxing with phosphorus tribromide in pyridine. similar procedures are taught by G. I. Samokhvalov et al., Proc. Acad. Sci. USSR,_84, 1179 (1952) and J. Gen. Chem. USSR, 26, 3111 (1956).

Application Example 1 Automotive Coatings Compositons To ascertain the effect on thermal durability and loss rate from a high solids thermoset acrylic coating composition containing an instant benzotriazole UV absorber, the following tests are carried out. A high solids thermoset acrylic clear coat is prepared by mixing an experimental acrylic polyol resin and hexamethoxymethylmelamine (Resimene ® 747, Monsanto) at a solids ratio of 60/40. The dodecylbenzene sulfonic acid catalyst (Nacure ® 5225; King Industries) is added at 0.70 % by weight. A flow aid Modaflow ® (Monsanto) is added at 0.25 % by weight to form a model acrylic melamine resin system. The model clear coat is reduced with xylene to a viscosity of 26-27 second using a Zahn #2 cup and applied via a conventional air spray at 50 psi (3.5 Kg/cm 2 ) over a 1" x 3" (2.54 x 7.62 cm) quartz slide. Cure is achieved by baking the slide for 30 minutes at 260°F (127°C). The clear coat is stabilized with 1% by weight of a hindered amine light stabilizer bis-(1-octyloxy-2,2,6,6-tetramethylpiperidin-4-yl) sebacate, Tinuvin ® 123 (Ciba). The various test UV absorbers are incorporated at about 5 mmol% by weight in the clear coat. The film thickness on the quartz slides range from 1.15 to 1.41 mils (0.029 to 0.036 mm). The films on the quartz slides are weathered according to the following conditions in Xenon Arc Weather-Ometer with a controlled irradiance at 6500 W, using inner quartz and outer borosilicate S-type filter. The irradiation cycle is as follows: 40 minutes of straight irradiation with no water spray, followed by 20 minutes of light plus front spray, followed by 60 minutes of light irradiation and finally by 60 minutes dart plus rear spray (condensation). The setting is at 0.55 W/m 2 at 340 nm, 1.98 kJ/hour. In the light cycle the black panel temperature is controlled at 70+2 °C. The relative humidity in the light cycle is in the range of 50-55% and in the dark cycle 100%. The absorbance of the long wavelength UV band as a function of Xenon arc weathering hours are recorded. To follow the loss of UV absorbers from the clear coats, UV spectra are measured initially and after weathering at regular intervals. The UV spectrophotometer measures absorbance linearly up to 5.5 absorbance units using a reference beam attenuation technique. It is assumed that the degradation products from the UV absorber do not contribute to the UV spectrum. This is tested by following the ratio of absorbance of the band at about 300 nm and the band at about 340 nm. The ratio does not change upon weathering the sample. This suggests that the UV spectrum of the weathered films correspond to the amount of UV absorber remaining in the film with very little if any contribution to the spectrum by photodegradants. Representative test compounds are incorporated into a high solid thermoset acrylic melamine resin at a concentration of 3% by weight to give equal molar concentrations of the test UV absorber in equal film thickness. The test samples are exposed for 1461 hours respectively. Compound Units of Absorbance Units of Absorbance Units of Abs.

The solution is applied to a glass slide. Subsequent to solvent evaporation and baking at 100° C for 1 hour, an optically clear silicone hardcoat is formed on the glass. The coatings are exposed to UV light by passing them five times under two 300 watt/inch medium pressure mercury lamps using a conveyor moving at about 25 ft/min. The silicone hardcoats prepared containing silylated addtives of the present invention, in particular compounds of Examples 107-115, exhibit excellent resistance to abrasion (Taber abrasion test); and microcracking resistance and low haze upon UV exposure. The samples are also exposed in an Atlas Ci35a WeatherOmeter at 0.77 W/m 2 irradiance at 340 nm with Type S borosilicate inner and outer filters. The lamp runs in a cycle of 160 minutes light at 45 °C dry bulb temperature and 50% relative humidity (ca. 65 °C black panel temperature) and 20 minutes dark. The last 15 minutes of the dark cycle is with a front and back side water spray. Under these conditions, the samples accumulate 2700 kJ/m 2 at 340 nm in 1100 hours of exposure. This is approximately equivalent to one year Florida exposure. The samples are mounted on the standard sample holders with spring clips.

Application Example 8 Thermal Permanence in Polymeric Coatings Silicone coatings are prepared with methyl trimethoxy silane and 2.5% by weight of the additives of the table below. The aqueous acidic coating compositions are applied by spin-coating to 1.5" diameter quartz discs under conditions which result in a dry film thickness of 2 microns. All discs are allowed to flash at room temperature for 20-30 minutes, then one i 1 set of discs is baked at 125°C for 60 minutes while another set is allowed to dry at room temperature at least overnight. Thermal permanence of the test compounds is determined by using Beer's Law equation relating absorbance directly to concentration. It is assumed that in the ambient cured coating, all UVA is retained, and has not volatilized. Therefore, the amount of a compound lost by volatilization under these baking conditions is determined either by comparison of the absorbance from the ambient cured and oven cured coating applied at the same film thickness in the case of reactable UV absorbers or by extraction of non-reactable UV absorbers and comparison of the amount of UV absorber extracted from the ambient- cured and oven cured samples. Results are below.

After oven cure at 125°C for 60 minutes, absorbance scans are run from 250 nm to 450 nm. If two absorbance peaks are present, the peak at longer wavelength is recorded in location (nm). Long wavelength spectra coverage is also recorded by obtaining absorbance values at 375 nm. Results are below.

Application Example 10 Reactability Coatings are prepared and coated on glass plates as in application Example 8. After ambient cure for 1 day, the coatings are removed from the glass substrate. Approximately 5 mg of the coating are weighed into a 10 ml volumetric flask, which is filled to mark with tetrahydrofuran (THF). After sonication for 60 minutes, the solution is filtered, then diluted to a known volume with THF. The amount of UVA extracted is determined by comparing the absorbance of the THF solution with absorbance of known standards. The percent reacted into the coating is calculated from the difference between the amount of UVA remaining in the coating after bake and the amount extracted. Results are found below.
