Abstract:
The invention relates to a process for coating plastic surfaces with metals, especially plastic surfaces composed of acrylonitrile/butadiene/styrene copolymers (ABS) and composed of mixtures of these copolymers with other plastics (ABS blends), using an etch solution (composition C) comprising at least one ionic liquid IL, wherein the process comprises the treating of the plastic surface after the etching with an aqueous rinse solution RS while applying ultrasound.

Claim (Index 1):
A process for coating a plastic surface with at least one metal, the process comprising:\n a) pretreating the plastic surface with a composition, comprising more than 50% by weight of an ionic liquid, wherein the ionic liquid is a salt which is liquid at 100\u00b0 C., 1 bar; b) primary treating the plastic surface from a) with an aqueous rinse solution while applying ultrasound; c) secondary treating the plastic surface from b) with an activator composition, comprising an ionogenic activator, a colloidal activator or both of the ionogenic and the colloidal activator; d) tertiary treating the plastic surface from c) with an accelerator composition, comprising an acid, a reducing agent, or both of the acid and the reducing agent; e) chemically depositing a metal layer, by treating the plastic: surface from d) with a first coating composition, comprising a metal salt and a reducing agent; f) electrochemically coating the plastic surface from e) with at least one additional metal layer, by electrochemically treating the plastic surface from step e) with at least one second coating composition, comprising a metal compound. wherein the plastic surface is a plastic comprising a polyimide, a polystyrene, a copolymer of styrene selected from a styrene/acrylonitrile copolymer, an acrylic ester/styrene/acrylonitrile copolymer and an acrylonitrile/butadiene/styrene copolymer, or a mixture thereof and/or a multicomponent plastic comprising the plastic.
