发明名称 Process for manufacturing electroformed patterns
摘要 A process for manufacturing electroformed patterns includes the following steps: forming electroformed closed line graphic patterns and an electroformed line surrounding said patterns (optionally together with an electroformed island) on a surface of a conductive substrate; peeling the electroformed patterns and the electroformed line (optionally together with the electroformed island) from the conductive substrate to transfer them onto a pressure-sensitive adhesive layer provided on a support; injecting or printing a coating material inside the closed line graphic electroformed patterns and converting the coating material to coating films; forming a firmly bonding adhesive layer on a whole surface of the support on its side where the electroformed patterns, the coating films and the electroformed line (optionally together with the electroformed island) are retained; removing the electroformed line (optionally together with the electroformed island); separating the electroformed patterns and the coating films from the support and, simultaneously therewith, adhering the electroformed patterns and coating films through the firmly bonding adhesive layer onto a surface of an adherend. This process enables simple formation of electroformed patterns provided with coating films which may be a luminous paint, and is suitable for making a timepiece face.
