    Abstract: The invention relates to a method for producing polymer-coated metal foils, comprising the following steps: (a) applying a base layer (7) onto a support foil (3), with a dispersion (5) which comprises electrolessly and/or electrolytically coatable particles in a matrix material, (b) at least partially drying and/or at least partially curing the matrix material, (c) forming a metal layer (19) on the base layer (7) by electroless and/or electrolytic coating of the base layer (7) comprising the electrolessly or electrolytically coatable particles, (d) applying a polymer (23) to the metal layer (19). Furthermore, the invention relates to a use of the polymer-coated metal foil for the production of printed circuit boards.

    Abstract: The invention relates to a method for producing metal-coated base laminates having a support (51) made of an electrically nonconductive material (37), which is coated on at least one side with a metal layer (25, 53). In a first step, a base layer (11) is applied onto a substrate (3) with a dispersion (5), which contains electrolessly and/or electrolytically coatable particles in a matrix material. The matrix material is at least partially cured and/or dried. A metal layer is subsequently formed on the base layer (11) by electroless and/or electrolytic coating. The support (51) made of the electrically nonconductive material (37) is laminated onto the metal layer (25). The support (51) laminated with the metal layer (25) and at least a part of the base layer (11) are subsequently removed from the substrate (3).

    Abstract: The invention relates to a method for the production of metal-coated base laminates having a carrier (51) made of an electrically non-conductive mate rial (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 coat ed in a current-free and/or galvanized manner. The matrix material is at lea st partially cured and/or dried. A metal coating is subsequently formed on t he 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 lamin ated onto the metal coating (25). As a final step, the carrier (51) is remov ed from the substrate (3) along with the metal coating (25) laminated thereo n and at least part of the base coating (11).
