The present invention relates to a method for producing a laminated layer composite, wherein at least one base layer (3) and at least one further layer (4), with a component (1) located in between, are laminated from two thermoplastic materials having different Vicat softening temperatures B/50 in two stages into a layer composite. The invention further relates to a layer design suitable for said method, to a laminated layer composite produced according to said method, and to a security and/or value document comprising such a laminated layer composite.

La présente invention concerne un procédé de production d'un composite multicouche laminé, selon au moins une couche de base (3) et au moins une autre couche de base (4), qui sont réalisées dans deux matières thermoplastiques ayant des températures de ramollissement Vicat B/50 différentes et entre lesquelles est intercalé un composant (1), sont laminées pour obtenir un composite multicouche. L'invention concerne également une structure en couche adaptée à ce procédé, un composite multicouche produit selon ce procédé et un document de sécurité et/ou de valeur contenant un tel composite multicouche laminé.
