The present invention concerns a method for the production of a moulded body containing at least one volume hologram by means of injection moulding, comprising the following method steps: provision of a hologram film composite having two sides comprising at least one photopolymer layer with at least one volume hologram, a shear protective layer and a substrate layer, and optionally, further composite film layers, insertion of the hologram film composite into a metallic injection mould, such that one side of the hologram film composite is at least partially in contact with the injection mould wall, introduction of a molten thermoplastic polymer for the production of the moulded body, wherein at least the outermost layer of the hologram film composite on the side of the hologram film composite coming into contact with the molten polymer contains essentially the same polymer raw materials as the molten thermoplastic polymer, and extrusion coating of the hologram film composite with the molten thermoplastic polymer, and solidification of the molten thermoplastic polymer. The invention also concerns a moulded body produced in this manner and advantageous applications of this moulded body.
