Abstract:
A pressure-sensitive adhesive double coated tape or sheet having a three-layer structure comprising an adhesive layer, a substrate layer and an adhesive layer, each of which is manufactured by the use of a light-cured adhesive whose main components are a (metha)alkyl ester acrylate monomer, a polar functional group containing monomer, an acrylic polymer having a photo-active functional group, and a photopolymerization initiating agent, wherein the acrylic polymer having a photo-active functional group has an average molecular weight of 200,000 to 3,000,000 and the content of the photo-active functional group is 0.001 milli-equivalent/g to 0.5 milli-equivalent/g.
