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.
摘要(中):
本发明提供了一种生产率优异的光学压敏粘合片,并且在将压光胶粘剂层压到光学部件之后,在高压釜处理之后的气泡的剩余部分或延迟气泡的产生中减少 。 本发明涉及一种光学压敏粘合片,其包含丙烯酸类压敏粘合剂层,其中丙烯酸类压敏粘合剂层通过活性能量射线聚合形成,丙烯酸类压敏粘合剂的凝胶分数 层的比例为80重量%以下,丙烯酸系粘合剂层的溶胶物中的分子量为50,000以下的成分的含量为20重量%以下。
