Abstract: A composite pane includes an outer pane having outer and inner surfaces, a first thermoplastic intermediate layer, a hologram element including a first set of holograms produced in one or more layers of a holographic material, wherein the first set of holograms includes a blue hologram that is activatable by blue light having a wavelength in a first range and is not responsive to light of other wavelengths, a green hologram that is activatable by green light having a wavelength in a second range and is not responsive to light of other wavelengths, and a red hologram that is activatable by red light having a wavelength in a third range and is not responsive to light of other wavelengths, an inner pane, and a color-selective optical filter for selective absorption of light.

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.
