US 2025/0092504 A1 · Metal Image Forming Method

Abstract

The metal image forming method of the invention utilizes a toner image as a resist pattern for metal image formation in a publicly known lift-off process, instead of using the toner image as a resist pattern during etching steps. A toner image is formed by formation and development of an electrostatic pattern directly on the substrate, without using a photosensitive body. The original toner image-formed surface, or the toner image-transferred surface, is covered with a metal layer by a physical vapor deposition method, after which the toner image is removed together with the metal layer on the toner image, to obtain a metal image. Transfer of a resin image onto a curved substrate, covering of the resin image-transferred surface with a metal layer by a physical vapor deposition method, and subsequent removal of the resin image together with the metal layer on the resin image, allows formation of a high-definition metal image on the curved substrate.
