ABSTRACT:
A photosensitive sheet is composed of a plastic film, a subbing layer for nonelectrolytic plating provided thereon consisting of a hydrophilic resin having swelling property and fine particles of a metal or a metallic compound, a nonelectrolytically plated layer provided on the subbing layer and the photoresist layer provided on the nonelectrolytically plated layer. A metal pattern is performed by the steps of: exposing patternwise to light the photoresist layer of the photosensitive sheet, developing the exposed photoresist layer to form a resist pattern on the nonelectrolytically plated layer; forming an electrolytically plated layer on the nonelectrolytically plated layer in the area having no resist; superposing the photosensitive sheet on a substrate; and separating the plastic film from the substrate, keeping both the resist pattern and the electrolytically plated layer on the substrate, to form a metal pattern on the substrate.
