Method for producing a composite pane with a functional element

A method for producing a composite pane, comprising, in the order indicated below:

• a) arranging a first thermoplastic intermediate layer, a second thermoplastic intermediate layer, and a third thermoplastic intermediate layer in full surface contact one above the other;
• b) joining the first thermoplastic intermediate layer, the second thermoplastic intermediate layer, and the third thermoplastic intermediate layer to form a preliminary composite;
• c) removing the third thermoplastic intermediate layer from certain regions to form an aperture,
• d) forming a layered stack by inserting a functional element into the aperture in the third thermoplastic intermediate layer;
• e) arranging the layered stack between a first pane and a second pane;
• f) joining the first pane and the second pane by lamination via the layered stack;
• and wherein the functional element has a thickness of ≥50 μm, and the third thermoplastic intermediate layer has a thickness that substantially corresponds to the thickness of the functional element,
• and outer dimensions of the aperture substantially correspond to outer dimensions of the functional element.
