СПОСОБ ВОСПРОИЗВЕДЕНИЯ И ЗАЩИТЫ РЕЛЬЕФА ПОВЕРХНОСТИ

摘要

A method of manufacturing at least a part of a metal container where a relief, e.g. a hologram with a diffracting optical element, is being replicated in the surface of a soft layer of a metallic substrate and subsequently the surface relief is covered with a transparent layer. The transparent layer stabilises the soft layer of the metallic substrate and thereby protects the relief. The metallic substrate is subsequently formed into a metal container.
