Abstract

In a process of making a microstructured plastic mold from which structures can be formed galvanically a compound layer including an electrically conductive and an insulating layer portion is provided and is heated, and impressed into the insulating layer portion is a tool which has microstructured bodies disposed thereon of a height corresponding at least to the thickness of the insulating layer portion and with rough front surfaces having points and ridges adapted to penetrate the electrically insulating layer thereby to expose the electrically insulating layer at the bottom of the cavities formed by microstructured bodies.
