Abstract
The present invention relates to a pressure-sensitive adhesive composition, a pressure-sensitive adhesive optical member, a pressure-sensitive adhesive polarizing plate, and a display device. The pressure-sensitive adhesive composition of the present invention can form a pressure-sensitive adhesive having excellent durability and light leakage prevention property under severe conditions such as a high temperature condition, a high temperature and high humidity condition, or under a severe condition where a high temperature/high humidity and a normal temperature/low humidity are repeated.
Claims17
A pressure-sensitive adhesive composition comprising:
- a block copolymer including a first block having a glass transition temperature of 50° C. or more and a second block having a glass transition temperature of −10° C. or less;
- an acrylic random copolymer including a cross-linkable functional group;
- and
- a multifunctional cross-linker,
- wherein the acrylic random copolymer has a number average molecular weight (Mn) of 200,000 or more, and
- wherein the acrylic random copolymer is comprised in an amount of 5 parts by weight to 50 parts by weight, relative to 100 parts by weight of the block copolymer.
