ABSTRACT:
The present invention relates to a process for preparing a laminated structure containing at least a main foil which is substantially impervious to light, B) at least one interlayer, and C) a covering foil which is substantially light-permeable. The layers are bonded together using a UV-curable and/or VIS-curable composition. The interlayer, prior to contact with the curable composition, is substantially impervious to the irradiation necessary for curing the curable composition and becomes transparent when impregnated with the curable composition so as to effect polymerization of multiple layers of curable composition in one irradiation step. The laminated structure is prepared by applying a layer of the curable composition to the main foil A), applying the interlayer B) to the main foil A), applying a further layer of the curable composition to the interlayer B), applying a covering foil C) to the interlayer B), and irradiating the laminated structure so obtained through the covering foil C) with UV- and/or VIS-radiation
