Title:
Adhesive layer with separator, its manufacturing method and optical film with adhesive layer with separator
Document Type and Number:
Japanese Patent JP6346413
Kind Code:
B2
Abstract:
A separator-attached pressure-sensitive adhesive layer of the present invention including a pressure-sensitive adhesive layer on a separator, wherein the separator includes a base film and an oligomer prevention layer, and a release layer provided in this order on the base film, and the release layer has a surface resistance value of 1.0×1013Ω/□ or more, and the pressure-sensitive adhesive layer is formed from a pressure-sensitive adhesive composition including a base polymer and an ionic compound and is provided on the release layer of the separator. The separator-attached pressure-sensitive adhesive layer is capable of inhibiting an oligomer contained in the base film used for the separator from migrating into the pressure-sensitive adhesive layer.
