Patent

CA 2542360

The invention concerns a film (66) having at least one electrical component and a process for the production of such a film. An adhesive layer comprising a radiation-cross-linkable adhesive is applied to a base film (61). The adhesive layer is applied to the base film in a form of being structured in pattern form and/or is irradiated in pattern form in such a way that the adhesive layer hardens with structuring in pattern form. A transfer film (41) which comprises a carrier film and an electrical functional layer is applied to the adhesive layer. The carrier film (41) is pulled off the film body comprising the base film, the adhesive layer and the electrical functional layer, wherein in a first region structured in pattern form the electrical functional layer remains on the base film (61) and in a second region structured in pattern form the electrical functional layer remains on the carrier film and is pulled off the base film (61) with the carrier film.

L'invention concerne un film (66) pourvu d'au moins un composant électrique, ainsi qu'un procédé de production d'un tel film. Selon l'invention, une couche constituée d'un adhésif réticulable par irradiation est appliquée sur un film de base (61) sous la forme d'un motif et/ou elle est irradiée selon le motif, de telle sorte qu'elle durcit de façon structurée, en formant le motif. Sur la couche d'adhésif est appliqué un film de transfert (41) qui comprend un film de support et une couche fonctionnelle électrique. Le film de support (41) est retiré du corps de film comportant le film de base, la couche d'adhésif et la couche fonctionnelle électrique, et, ainsi, la couche fonctionnelle électrique reste sur le film de base (61) dans une première région structurée en forme de motif et dans une seconde région structurée en forme de motif, la couche fonctionnelle électrique restant sur le film de support et étant retirée du film de base (61) avec le film de support.
