Abstract
Provided are a pressure-sensitive adhesive composition, a protection film, an optical laminate, a polarizing plate, and a display device. Provided is the pressure-sensitive adhesive composition which is excellent in various physical properties, such as endurance reliability, has excellent antistatic characteristics that change little over time. The pressure-sensitive adhesive composition can be used for a protection film, or can be used for an optical film, such as a polarizing plate, for example.
Claims18
A pressure-sensitive adhesive composition comprising:
- a block copolymer including a first block having a glass transition temperature of 50° C. or higher, and a second block having a glass transition temperature of −10° C. or lower, the second block including a copolymer which is derived from (meth)acrylic acid ester monomer, a copolymeric monomer having a cross-linkable functional group, and a compound containing a nitrogen atom;
- and
- an antistatic agent,
- wherein the first block consists of a homopolymer which is derived from (meth)acrylic acid ester monomer,
- the block copolymer is a diblock copolymer having the first block and the second block, and
- the diblock copolymer is the only block copolymer in the pressure-sensitive adhesive composition.
