The invention relates to a method for the production of metal-coated base laminates having a carrier (51) made of an electrically non-conductive material (37) that is coated on at least one side with a metal coating (25, 53). In a first step, a base coating (11) is applied onto a substrate (3) having a dispersion (5) containing particles in a matrix material that can be coated in a current-free and/or galvanized manner. The matrix material is at least partially cured and/or dried. A metal coating is subsequently formed on the base coating (11) by means of a current-free and/or galvanic coating. The carrier (51) made of the electrically non-conductive material (37) is laminated onto the metal coating (25). As a final step, the carrier (51) is removed from the substrate (3) along with the metal coating (25) laminated thereon and at least part of the base coating (11).

La présente invention concerne un procédé de réalisation de laminés de base dotés d'un revêtement métallique, comprenant un support (51) constitué d'un matériau (37) électriquement non conducteur et dont au moins un côté est revêtu d'une couche métallique (25, 53). Au cours d'une première phase, une couche de base (11) est appliquée sur un substrat (3) avec une dispersion (5) qui contient des particules qui peuvent être appliquées sous forme de couche sans courant et/ou par galvanisation, dans une matière matricielle. La matière matricielle est durcie et/ou asséchée au moins partiellement. Puis une couche métallique est formée sur la couche de base (11) par revêtement sans courant et/ou galvanisation. Le support (51) en matériau (37) électriquement non conducteur est laminé sur la couche métallique (25). Pour finir, le support (51) et la couche métallique (25) sur laquelle il est laminé, ainsi qu'au moins une partie de la couche de base (11) sont retirés du substrat (3).
