  • Publication number: 20100176090
    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).
