Workpiece machining sheet and manufacturing method of the finished workpiece

Abstract

Issue: To provide a workpiece processing sheet that exhibits excellent pick-up properties even after heat treatment. Solution: A workpiece processing sheet having a substrate and an adhesive layer laminated on one surface of the substrate, wherein the adhesive layer is composed of an adhesive composition containing an active energy line curing polymer and a hindered amine stabilizer, the active energy line curing polymer having free radical generating groups and active energy line polymerizable groups on its side chains that initiate polymerization reactions under the excitation of an active energy line.
