Title:
ADHESIVE AGENT SHEET HAVING TRANSPARENT ADHESIVE AGENT LAYER
Document Type and Number:
WIPO Patent Application WO/2015/108160
Kind Code:
A1
Abstract:
Provided is an adhesive agent sheet which can be produced readily at low cost, and which contains an adhesive agent layer that can effectively prevent the occurrence of internal reflection when used for the bonding of optical member laminates. In the region extending to a specified thickness from the surface of the adhesive agent layer, a refractive index controlling zone having a higher refractive index than that of a base material for the adhesive agent layer is formed. By employing this configuration, the occurrence of internal reflection in a laminate formed using optical members can be prevented when the adhesive agent layer is used for the bonding of the optical members. Disclosed is an adhesive agent sheet comprising a support and a transparent adhesive agent layer formed on the support. In the adhesive agent sheet, the adhesive agent layer is composed of: a base adhesive agent zone which is formed in a region extending to a specified thickness from one main surface of the adhesive agent layer and is made substantially from a transparent adhesive agent base material; and a transparent adhesive refractive index controlling zone which is formed in a region extending to a specified thickness from the other main surface of the adhesive agent layer. The refractive index controlling zone has a higher refractive index than that of the adhesive agent base material.
