Method for producing a curved substrate panel with a hologram, resulting substrate panel with hologram and a laminate containing such a substrate panel, in particular a vehicle window

A method of producing a curved substrate pane having a hologram, the method comprising:

• producing the curved substrate pane from plastic by primary forming, injection molding or injection compression molding between a first mold half that defines a predetermined target geometry of a substrate surface and a second mold half separably fixed to the first mold half;
• removing the first mold half from the second mold half in which the curved substrate pane remains, and applying a holography master in a form of a thin layer to a surface defining the target geometry in the first mold half or a further mold half;
• fixing the first mold half or the further mold half having the holography master on the second mold half to leave an empty gap of a predetermined constant thickness between the holography master and the substrate surface of the curved substrate pane that has remained in the second mold half since the producing of the curved substrate pane, and filling the gap with a hologram recording material;
• and
• exposing a hologram recording layer formed thereby between the substrate surface and the holography master with a coherent light to form the hologram in the hologram recording layer, wherein the hologram is defined by the holography master.
