PRESSURE SENSITIVE ADHESIVE FOR OPTICAL USE, PRESSURE SENSITIVE ADHESIVE SHEET FOR OPTICAL USE AND OPTICAL COMPONENT HAVING PRESSURE SENSITIVE ADHESIVE LAYER

摘要

The present invention relates to an optical adhesive, an optical adhesive sheet and an optical component with an adhesive layer. The optical adhesive is obtained through crosslinking an adhesive forming material. The adhesive forming material comprises the following components: (A) (meth)acrylate polymer which comprises the following three components as structural units: 5-90wt% of (a-1) (meth)acrylate monomer which comprises oxyalkylene groups, less than 10wt% of (a-2) (meth)acrylate monomer which comprises reactive groups, and (a-3) (meth)methacrylate; (B) (meth)acrylate polymer which comprises (meth)acrylate monomer with reactive groups as structural unit; (C) an active energy linear curing compound; and (D) anstatic agent. Furthermore the content proportions of the component (A) and the component (B) are 100:1-100:50 by mass.
