MANUFACTURING METHOD OF DOUBLE SIDED ADHESIVE SHEET AND DOUBLE SIDED ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a double sided adhesive sheet multi-layering photopolymerizable resins having different physical properties without loss of an optically-transparent cover film with high yield.SOLUTION: A manufacturing method of a double sided adhesive sheet having plural resin layers having different physical properties includes: (1) a step of applying plural photopolymerizable resin compositions on a surface targeted for application concurrently, and forming plural resin layers; (2) a step of laminating an optically-transparent film on the formed resin layers; and (3) a step of applying ultraviolet light or electron beam after the laminating and hardening the resin layers.SELECTED DRAWING: Figure 1
