Document Type and Number:
Japanese Patent JP5842825
Kind Code:
B2
Abstract:
The present invention is: an optical adhesive resin composition containing (A) a (meth)acrylate polymer and (B) a (meth)acrylate monomer, the optical adhesive resin composition being characterized by the (meth)acrylate polymer having an amide group; and an optical adhesive sheet formed by curing the optical adhesive resin composition into a sheet shape. The present invention is able to provide: the optical adhesive resin composition, which has excellent transparency, has sufficient adhesion to plastic front plates and touch panels, has the shock absorbance necessary to protect an image display device, has the flexibility and handling characteristics necessary for producing an image display device provided with a plastic front plate, and is suitable for application in an image display device; and an optical adhesive sheet using the optical adhesive resin composition.
