    Abstract: Dispersion for applying a metal layer on an electrically non-conductive substrate comprises an organic binder component (0.01-30 wt.%); a metal component (30-89.99 wt.%) containing a first metal with a first metal particle (0.01-99.99 wt.%) and a second metal with a second metal particle (99.99-0.01 wt.%); and a solvent component (10-69.99 wt.%); where the first metal and -particle and second metal and -particle are different from each other. Independent claims are included for: (1) a method for preparing the dispersion comprising mixing an organic binder component, a metal component containing a first metal with a first metal particle and a second metal with a second metal particle, a solvent component, dispersing agent, filler components and further components, and dispersing the obtained mixture; (2) preparation of metal layer on at least a part of an electrically non-conductive substrate comprising applying the dispersion on the substrate, drying the dispersion applied layer on the substrate and optionally de-energizing and/or galvanically separating the metal on the dried dispersion layer; and (3) a substrate surface comprising at least a partially electrical conductive metal layer.

    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).
