Particularly preferred are saturated aliphatic monocarboxylic acids such as palmitic acid, stearic acid and hydroxystearic acid.
- the saturated, aliphatic Cj 0 to C 3 6-carboxylic acids and the fatty acid esters are as such either known from the literature or can be prepared by literature methods.
- Examples of pentaerythritol fatty acid esters are those of the particularly preferred monocarboxylic acids mentioned above.

- esters of Guerbet alcohols and of glycerol with stearic acid and palmitic acid and optionally hydroxystearic acid are particularly preferred.
- the multilayered products according to the invention may contain organic dyes, inorganic color pigments, fluorescent dyes and particularly preferably optical brighteners.
- the compound (a) is either (i) coextruded with polycarbonate in such a way that a thin UV protective layer of compound (a) is well adhering to the polycarbonate surface, or (ii) the compound (a) becomes thin Foil further processed, which is then back-injected or laminated with polycarbonate to form a well-adhesive composite.
- a paint formulation comprising (bl) a polyalkyl (meth) acrylate resin containing methyl methacrylate as main component and possibly another alkyl methacrylate with a longer, linear or branched alkyl
- the UV absorber-containing paint formulation (b) by means of flooding, dipping, spraying, rolling or spin coating is applied to the surface of a polycarbonate molding and then physically dried so that results in a well-adherent coating on PC.
- a further advantage of the inventive multilayered products produced in this way is that the UV protective layer can be overcoated with scratch-resistant or abrasion-resistant coating systems.
- a formulation of a scratch-resistant or abrasion-resistant paint for example but not exclusively, a polysiloxane, a silicate coating (water glass), or a nanoparticle-containing formulation by flooding, dipping, spraying, rolling or spin coating is applied to the surface of the UV protective layer and then cured to a well-bonded composite PC / UV-protective layer / scratch-resistant layer.
- those multilayer products are preferred which are selected from the group consisting of plates, films and three-dimensional molded parts.
- the present invention is the use of said multi-layered products, especially for outdoor applications with permanently high demands on the visual impression, such as the glazing.
- the used optical quality polycarbonate Makrolon 2808 10 x 15 x 0.32 cm polycarbonate sheets were cleaned, dried and blown off with ionized air. Subsequently, the UV protective coating formulation was applied by flooding, flashed and then cured for 30 min at 50 0 C in a convection oven. The thickness of the transparent coating thus obtained was determined by means of an Eta SD 30 from Eta Optik GmbH to 7 to 10 microns along the plate in the direction of flow.
- the initial absorbance of the coating of Example 1 is at 340 nm 5.0 and has a degradation of 0.049 MP 1 .
- the yellowness index is calculated as follows: First, the wavelength-dependent yellowing of the material is determined by the spectral sensitivity method (Interpretation of the spectral sensitivity and of the activation spectrum of polymers, P. Trubiroha, Proceedings of the XXJJ Donau Stamm dealte, 17.8.2001, Berlin , Page 4-1). Then calculate the spectral distribution of the UV light of the sun behind the UV protection layer. From these two data sets, the yellowing after weathering can be calculated in a known manner by folding and integration over time. (Fundamentals of life-time prediction in weathering, A. Mackig, V. Wachtendorf, Proceedings 34th Annual Meeting of the Society for Environmental Simulation, Environmental Impacts capture, simulate and evaluate, 2.3.2005, Pfinztal, page 159).
- ⁇ YI is the change in yellowness YI of the substrate material which must be protected by the UV absorber.
- T is the weathering time and F is the weathering spectrum.
- Ext ( ⁇ , t) is the wavelength-dependent and with time by degradation decreasing extinction of the UV Absorber and SR ( ⁇ , YT) the wavelength and yellow value-dependent spectral sensitivity of the substrate material.
- UV absorber CGL 479 and Laclcmatrix thus fulfills the requirements with respect to extinction and degradation and therefore leads to a low yellowing.
- Example 1 Comparative example identical to Example 1 except for the use of a non-inventive UV absorber (Chimassorb 81).
- the preparation of the UV protective layer is carried out analogously to Example 1, wherein instead of 10 wt .-% based on the solids content of the paint formulation of CGL 479 10 wt .-% based on the solids content of the paint formulation of Chimassorb 81 (2-hydroxy-4- ( octyloxy) benzophenone from Ciba Specialty Chemicals) was used.
- the preparation of the UV protective layer is carried out analogously to Example 1 , wherein instead of 10 wt .-% based on the solids content of the paint formulation of CGL 479 only 1 wt .-% based on the solids content of the paint formulation of CGL 479 was used.
- the used optical quality polycarbonate Makrolon 2808 10 x 15 x 0.32 cm polycarbonate sheets were cleaned, dried and blown off with ionized air. Subsequently, the paint formulation was applied using a doctor blade, and allowed to vent to room temperature at room temperature. The thickness of the transparent coating thus obtained was determined to be about 23 ⁇ m by means of an Eta SD 30 from Eta Optik GmbH.
- the UV absorber degradation rate was determined as described in Example 1.
- the initial absorbance of the coating of example 5 at 340 nm is 1.3 and has a degradation of 0.096 MJ -1 , and thus more than 4 times as much as in example 3, which has a comparable initial extinction, ie with this protective layer only a UV Converted into an increase in yellowness after 30 MJ / m2 at 340 nm (equivalent to 10 years Florida) for polycarbonate of the type AL 2647 (see Example 1) gives a ⁇ YI value of 18, 1, whereby the erf ⁇ ndungszelen requirements are not met.
- composition bisphenol A polycarbonate (Makrolon Type AL 2647 (medium-viscosity bisphenol A-poly- carbonate with UV stabilizer and mold release agent; MFR 13 g / l 0min after ISOL 133 at 300 0 C and 1.2 kg)) / UV-protective Layer with CGL 479 as UV absorber in a PMMA coating matrix / abrasion-resistant topcoat based on a siloxane coating
- Example 1 the solids content of the paint consisting of a 2 to 1 mixture of the dissolved polymethacrylate from Example 1 and the solvent mixture used as a diluent (see also Example 1), this time to 13.23% determined.
- Example 1 12 g of the dissolved polymethacrylate (see Example 1) are mixed with 6 g of the solvent mixture used as diluent (see also Example 1) and stirred for about 5 minutes. 0.199 g of CGL 479 (corresponding to 5% by weight, based on the above-defined solids content without UV absorber), 0.024 g of a HALS system (Tin.
- the siloxane varnish (Silvue MP 100) from SDC Technology Inc. stored in the refrigerator at about 8 ° C. is brought to room temperature with stirring.
- the AL 2647 panels provided with the UV protective layer are blown off with ionized air on the coated side, overcoated with the Silvue MP 100 lacquer in the same flow direction as the UV protective lacquer, then flashed off and then at 100 for 1 h 0 C cured in a convection oven.
- the total thickness of the thus obtained optically flawless, transparent two-layer coating of UV protection layer and topcoat was determined by means of an Eta SD 30 from Eta Optik GmbH to 8 to 14 microns along the plate in the flood direction.
- the base material Makrolon was melted (296 0 C and melt pressure 99 bar Speed 65.7 min "1, melt temperature) 3108 after pre-drying (4 hours at 120 0 C) on the Haupextruder.
- the Coexmaterial was consisting of the pre-dried at 100 0 C 3h UV protection compound (see above) via a coextruder (speed 10 min “1 , melt temperature 286 ° C and melt pressure 54 bar) and transferred together with the base material via a plate nozzle on a rolling mill ,
- the coex film thus obtained had a base material thickness of about 400 ⁇ m and a UV Coex protection layer of about 10 ⁇ m.
- the UV absorber degradation of CGX UVA 006 in the UV coextrusion layer on Makrolon 3108 was determined as described in Example 1.
- the initial extinction of the coex layer is 3.3 nm at 340 nm and has a degradation of 0.036 MJ -1 and thus offers a UV protection effect for> 30 MJ / m 2 at 340 nm, ie this UV protective layer fulfills the requirements according to the invention with respect to long-term stability. Converted into an increase in yellowness after 30 MJ / m2 at 340 nm (equivalent to 10 years Florida) for polycarbonate of the type AL 2647 (see Example 1), this gives a ⁇ YI value of 0.5.
