Abstract: A laminated pane includes first and second panes, a layer stack arranged therebetween including a first thermoplastic intermediate layer, a separating layer, a photopolymer layer with at least one holographic element, a carrier layer, and a second thermoplastic intermediate layer, wherein the photopolymer layer has a thickness of 5 μm to 50 μm, the carrier layer contains polyethylene terephthalate (PET), polyethylene (PE), polymethyl methacrylate (PMMA), polycarbonate (PC), polyamide (PA), polyvinyl chloride (PVC), and/or cellulose triacetate (TAC) and has a thickness of 20 μm to 100 μm, wherein the carrier layer is arranged directly adjacent the photopolymer layer, and the separating layer contains polyethylene (PE), polyvinyl chloride (PVC), and/or polymethyl methacrylate (PMMA) and has a thickness of 10 μm to 300 μm.

Abstract: A composite pane includes first and second panes, a layer stack arranged therebetween including a first thermoplastic intermediate layer, a separating layer, an adhesive layer, a photopolymer layer having a holographic element, a carrier layer, and a second thermoplastic intermediate layer. The carrier layer contains polyethylene terephthalate, polyethylene, polymethyl methacrylate, polyvinyl chloride, and/or cellulose triacetate and has a thickness of 20 μm to 100 μm. The carrier layer is arranged directly adjacent the photopolymer layer. The separating layer contains polyethylene terephthalate, polyethylene, polymethyl methacrylate, polycarbonate, polyamide, polyvinyl chloride, and/or cellulose triacetate and has a thickness of 10 μm to 300 μm. The adhesive layer is arranged directly adjacent the photopolymer layer and the separating layer.
