US 2015/0086781 A1 · PRESSURE-SENSITIVE ADHESIVE COMPOSITION

Abstract

Provided are a pressure-sensitive adhesive composition, an optical member, a polarizing plate and a display device. The pressure-sensitive adhesive composition having physical properties required for an optical member using a particular block copolymer and an antioxidant or a photostabilizer, which forms a fine phase change region in a crosslinking structure, and particularly having excellent bending preventability and storage stability may be provided. Such a pressure-sensitive adhesive composition may be used for optical uses, for example, to laminate various optical members, or apply an optical member to a display device.

Dependent claims

A pressure-sensitive adhesive composition, comprising:

a block copolymer including a first block having a glass transition temperature of 50 to 100° C. and a second block having a glass transition temperature of −30° C. or less and a crosslinkable functional group;
and
an antioxidant or photostabilizer.

Dependencies are inferred from the claim text.
