Optical pressure-sensitive adhesive sheet

摘要

The present invention provides an optical pressure-sensitive adhesive sheet excellent in the productivity, and is reduced in the remaining of an air bubble after an autoclave treatment or the generation of a delayed bubble when laminating the optical pressure-sensitive adhesive sheet to an optical member. The present invention relates to an optical pressure-sensitive adhesive sheet, which comprises an acrylic pressure-sensitive adhesive layer, wherein the acrylic pressure-sensitive adhesive layer is formed by an active energy ray polymerization, a gel fraction of the acrylic pressure-sensitive adhesive layer is 80 wt% or less, and a content of a component having a molecular weight of 50,000 or less in a sol matter of the acrylic pressure-sensitive adhesive layer is 20 wt% or less.
