The invention relates to a process for coating plastics or plastic surfaces with metals, especially plastics composed of acrylonitrile/butadiene/styrene copolymers (ABS) and composed of mixtures of these copolymers with other plastics (e.g. ABS blends), wherein the process comprises the pretreatment of the plastic surfaces with a composition C (etch solution) comprising at least two different ionic liquids IL1 and IL2.
