PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRESSURE-SENSITIVE ADHESIVE LAYER AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

PURPOSE: An adhesive composition is provided to have an excellent wettability, and to be able to provide an adhesive sheet capable of preventing the generation of bubbles as the adhesion to a substance to be adhered is excellent without separate pressurization. CONSTITUTION: An adhesive composition includes (A) acrylic polymer (B) polyoxyalkylene alkyl ether with the molecular weight of 200-1000. The content of (B) polyoxyalkylene alkyl ether is 0.1-100.0 parts by weight to 100.0 parts by weight of (A) acrylic polymer. (B) polyoxyalkylene alkyl ether is polyoxypropylene alkyl ether. (A) acrylic polymer includes 80-99.9 weight% of alkyl (meth)acrylate having at least C4-18 alkyl and 0.1-20 weight% of functional group-containing monomer as a monomer component.
