(IN201727040007)  Disclosed by the attached claims. 77662. PCT/EP2016/059737 Claims 1. A self-cleaning composite material comprising the following composition: 50. 85% in weight of mineral charges;  - 10-30% of polymer;  - photocatalytic Titanium Dioxide ( 02) dispersed in the crosslinking polymer in a weight percentage of 0.05% - 5% with respect to the weight of the cross-linking polymer;  Compatibilizing agent for anchoring between the photocatalytic 0 2 and the polymer, wherein said anchoring compatibilizing agent of the Ti02 is silane;  and cross-linking monomers in order to obtain the cross-linking of the polymer characterized in that said mineral charges comprise alumina trihydrate (ATH), and said cross-linking polymer comprises polyester resin. 2. The self-cleaning composite material of claim 1, wherein said alumina trihydrate (ATH) has a grain size of 10-50 micron. 3. The self-cleaning composite material of claim 1 or 2, wherein methyl methacrylate (MMA) is added to said polyester resin in a weight percentage lower than 15% of the weight of the polyester resin and methyl methacrylate (MMA) mixture 4. The self-cleaning composite material of any one of the preceding claims, wherein said silane is 3-(trimethoxysilyl) propyl methyl methacrylate and said silane is in double quantity with respect to the photocatalytic Ti02. 5. The self-cleaning composite material as claimed in any one of the preceding claims, wherein said composition also comprises silanization catalysts, such as isopropylamine ( IPA) and/or methacrylic acid (AMA). 6. The self-cleaning composite material as claimed in any one of the preceding claims, wherein said photocatalytic titanium dioxide is in 77662. PCT/EP2016/059737 Anatase form and in powder with a grain size lower than 300 nm. 7. The self-cleaning composite material as claimed in any one of the preceding claims, characterized in that said cross-linking monomers comprise ethylene glycol dimethacrylate (EGDM), tetraethylene glycol methacrylate (TEGDM) and trimethylolpropane trimethacrylate (TMPTMA). 8. The self-cleaning composite material as claimed in any one of the preceding claims, characterized in that it also comprises fine particles of the silicate family, such as quartz and/or hollow or solid glass microspheres, with grain size lower than 0.1 mm, in a weight percentage comprised between 2% and 15% with respect to the weight of the total composition. 9. A production process of a self-cleaning composite material, Comprising the following steps: - preparation of a polyester resin in a quantity corresponding to 10. % - 30% of the final product weight;  Dispersion of silane in said polyester resin;  Agitation of the polyester resin and silane mixture;  Dispersion of photocatalytic titanium dioxide (Ti02) in the polyester resin and silane mixture, in a weight percentage of 0.05% - 5% With respect to the weight of the polyester resin, Agitation of the polyester resin, silane and titanium dioxide (Ti02) mixture;  Addition of the following components to the mixture: 50% - 85. % in weight of alumina trihydrate (ATH)-based mineral charges and cross-linking monomers in order to obtain the reticulation of the polyester resin;  Agitation of the final mixture;  Polymerization of the mixture in a mold. 10. The process of claim 9, wherein said silane is added in a double quantity with respect to the photocatalytic Ti02. 11. The process of claim 9 or 10, wherein said agitation steps of 77662. PCT/EP2016/059737 The polyester resin and silane mixture and of said polyester resin, silane and titanium dioxide ( 02) mixture are made with a screw agitator at a speed comprised between 900 rpm and 1800 rpm respectively for a time of 30 minutes and 2.5 hours before adding the other components. 12. The process of any one of claims 9 to 11, wherein said polymerization step in the mold is made at an initial temperature of 50.deg.C That increases gradually to 100.deg.C for a time of 8 hours. 13. The process of any one of claims 9 to 11, wherein said polymerization step is performed chemically, at room temperature, by means of one or more of the following catalysts: TBPM (Tert-Butyl Peroxymaleate), in percentage from 0.5% to 2. 0%, Ca(OH)2 (calcium hydroxide) in percentage from 0.5% to 1.0%, PETMP Pentaerythritol Tetra(3-mercaptopropionate) in percentage from 0.1 % to 1.0%.
