A process for producing a composite material or a precursor thereof includes the steps: (i) printing a support material (A1) with an ink (D) which can be cured by irradiation with light, the support material (A1) (a) being impregnable with a curable resin (B) which after curing is transparent and light-stable, and (b) having a translucency, based on the overall thickness, of 10-95%, preferably 20-90%, more preferably 30-80% for light in the wavelength range of 200-500 nm; (ii) curing the ink (D) by irradiation with light; (iii) impregnating the thus-treated support material (A1) with a curable resin (B) which after curing is transparent and light-stable, and optionally combining the support material (A1) with at least one further support material (A2); and (iv) curing the curable resin (B) simultaneously with or after step (iii); and also relates to the material obtainable by this process.
