摘要：
The present invention relates to an acrylic pressure-sensitive adhesive double coated tape or sheet, an acrylic non-substrate pressure-sensitive adhesive transfer tape or sheet, and a method for manufacturing the same. The acrylic pressure-sensitive adhesive double coated tape or sheet and the acrylic non-substrate pressure-sensitive adhesive transfer tape or sheet are 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 photopolymerization initiating agent, wherein the acrylic polymer having a photo-active functional group has a weight average molecular weight of 200,000 to 3,000,000 and the content of the photo-active functional group of 0.001 milli-equivalent/g to 0.5 milli-equivalent/g.
