PRESSURE-SENSITIVE ADHESIVE SHEFET

摘要

PROBLEM TO BE SOLVED: To prepare a pressure-sensitive adhesive sheet which effectively inhibits the migration of an ultraviolet light absorber in a substrate layer to a pressure- sensitive adhesive layer to improve weatherability. SOLUTION: This pressure-sensitive adhesive sheet is obtained by laminating a pressure-sensitive adhesive layer on one side of a flexible vinyl chloride resin film as the substrate layer, and an ultraviolet light absorber has been added to the substrate layer and the pressure-sensitive adhesive layer, respectively.
