LIGHT-SENSITIVE SHEET, LIGHT-SENSITIVE LAYERS, IMAGE PATTERN FORMING METHOD AND WIRING PATTERN FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a light-sensitive sheet and light-sensitive layers easily forming desired patterns of different thicknesses within an image.

SOLUTION: In the light-sensitive sheet comprising a support, a first light-sensitive layer and a second light-sensitive layer in this order, wherein each of the first and second light-sensitive layers independently contains a binder, a polymerizable compound and a photopolymerization initiator, sensitivity is regulated so that the sensitivity of the second light-sensitive layer to light is made higher than that of the first light-sensitive layer. The light-sensitive layers are obtained by stacking the second light-sensitive layer and the first light-sensitive layer in this order on a substrate.
