PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRESSURE-SENSITIVE ADHESIVE LAYER, PRESSURE-SENSITIVE ADHESIVE SHEET, OPTICAL MEMBER, AND TOUCH PANEL

摘要

Provided is an optical member which has the excellent effect of being prevented from corroding, while retaining adhesion reliability and transparency to a high degree. A pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet are also provided with which it is possible to efficiently produce such optical member at a low cost. This pressure-sensitive adhesive composition is characterized by containing a rust preventive and either a mixture of monomer ingredients for constituting a base polymer or a product of partial polymerization of a mixture of monomer ingredients for constituting a base polymer, the monomer ingredients including no or substantially no acidic-group-containing monomer, and by containing no or substantially no organic solvent. The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer formed from the pressure-sensitive adhesive composition.
