Claim 0:
1. A method for producing a laminated pane with a functional element with electrically switchable optical properties, the method comprising:
a) creating a first stack of layers from, in this order, at least
a first pane,
a first thermoplastic laminating film,
at least one separating film,
a second thermoplastic laminating film,
a second pane,

wherein the first thermoplastic laminating film and/or the second thermoplastic laminating film are each formable by one or a plurality of polymeric films,
b) laminating the first stack of layers from step a) while being heated, wherein the first thermoplastic laminating film adheres to the first pane and the second thermoplastic laminating film adheres to the second pane,
c) taking the first pane with the first thermoplastic laminating film off the second pane with the second thermoplastic laminating film and the at least one separating film is removed from the stack of layers,
d) providing a functional element comprising an active layer,
e) placing the functional element on the first thermoplastic laminating film of the first pane or the second thermoplastic laminating film of the second pane and covered with the second thermoplastic laminating film with the second pane or with the first thermoplastic laminating film with the first pane, whereby a second stack of layers is formed from at least
the first pane,
the first thermoplastic laminating film,
the functional element,
the second thermoplastic laminating film,
the second pane, and

f) laminating the second stack of layers to form a laminated pane,
wherein the at least one separating film is detachable residue-free from the first thermoplastic laminating film and the second thermoplastic laminating film.
