ACRYLIC ADHESIVE COMPOSITION, ADHESIVE OBTAINED USING SAME, POLARIZING PLATE ADHESIVE, AND IMAGE DISPLAY DEVICE

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. 本发明提供种粘接剂组合物，作为将偏光板与玻璃基板等贴合的偏光板用粘接剂使用时可获得耐湿热白化性、初始耐久性优异且保存稳定性(经时后的耐久性)也优异的粘接剂层。该丙烯酸系粘接剂组合物特征在于，其含有丙烯酸系树
