PROBLEM TO BE SOLVED: To provide a method as well as an electrolyte for the electrolytic deposition of a mat or half-glossy copper layer from an acid electrolyte on a matrix such as metallic plastics in a pull-through device. SOLUTION: The method according to this invention is operated with current densities between 10 and 100 A/dm<SP>2</SP>and electrolyte temperatures between 22 to 60°C and is suitable for depositing the mat or half-glossy copper layer in the high-speed pull-through device. The electrolyte comprises at least copper, an alkyl sulfonic acid, halide ions, an ethoxylate and a naphthalene condensation product. COPYRIGHT: (C)2006,JPO&NCIPI
