PRESSURE SENSITIVE ADHESIVE COMPOSITION AND PRESSURE SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To prepare a pressure sensitive adhesive sheet having high strength and excellent in flexibility. SOLUTION: The basic material of this pressure sensitive adhesive sheet includes a first resin component comprising t-butylacrylate and a second resin component comprising phenoxyethylacrylate and the amount of the first and the second resin components is 2.5 to 20 wt.% in the total basic material. A polymer having high strength and excellent flexibility is obtained by polymerizing to the basic material by ultraviolet rays. The pressure sensitive sheet 50 having pressure sensitive adhesive layers 53, 57 comprising the hardened product of the pressure sensitive adhesive composition, is excellent in adhering property to curved surfaces.
