Document Type and Number:
Japanese Patent JP6950530
Kind Code:
B2
Abstract:
Provided is an adhesive composition capable of providing a superior adhesive layer having excellent resistance to whitening due to heat and humidity, excellent initial durability, and excellent storage stability (durability over time) when used as a polarizing plate adhesive for pasting together a polarizing plate and a glass substrate or the like. The acrylic adhesive composition contains an acrylic resin (A) and a silane coupling agent (B) containing at least one each of a reactive functional group and an alkoxy group in a structure, and is characterized in that the acrylic resin (A) contains 5-50 wt% of structural units derived from at least one polar group-containing monomer (a1) selected from a hydroxyl group-containing monomer, a carboxyl group-containing monomer, and a nitrogen-containing monomer, and at least one of the alkoxy groups contained in the silane coupling agent (B) is a C2-8 alkoxy group.
