DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET, PRODUCTION METHOD OF DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET, PRESSURE-SENSITIVE ADHESION TYPE OPTICAL FUNCTIONAL FILM AND PRESSURE-SENSITIVE ADHESION TYPE HARD COAT FILM

摘要

PURPOSE: A double-sided pressure-sensitive adhesive sheet, a manufacturing method thereof the pressure-sensitive adhesive photo functional film, and a pressure-sensitive adhesive hard coating film are provided to improve the durability and the transparency of the double-sided pressure-sensitive adhesive sheet. CONSTITUTION: A double-sided pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer formed with a pressure-sensitive adhesive composition. The sol fraction of the pressure-sensitive adhesive layer obtained by an ethyl acetate extracting process, has the weight average molecular weight of 50,000~500,000.
