Abstract: The invention is directed to a method of providing a plastic substrate with a metallic pattern and to a plastic substrate with a metallic pattern obtainable by said method. The method of the invention comprises i) replicating a pattern of recesses and protrusions on a plastic substrate by pressing a stamp having recesses and protrusions against the substrate, thereby providing said plastic substrate with recesses and protrusions; ii) removing said stamp from said substrate; iii)—applying a layer of seed material capable of initiating an electroless or electrochemical metal deposition process onto said plastic substrate in a selective pattern at least in the recesses of said plastic substrate to yield a substrate wherein said seed material remains selectively in the recesses of said substrate; and thereafter iv) using said seed material to initiate a metal deposition process.
