The present invention relates to an adhesive composition and a protective film including an adhesive layer formed by using the same, wherein the adhesive composition includes an acrylic copolymer formed by polymerizing a monomer mixture, the monomer mixture including a monomer represented by [Formula 1], a (meth)acrylic monomer including a carboxy group, a (meth)acrylic monomer including a cross-linkable functional group, and an alkyl(meth)acrylate-based monomer, wherein the acrylic copolymer has a polymerization conversion rate of 99 wt % or higher.

Adhesive composition and protective film produced using same

Provided are a pressure-sensitive adhesive composition for an optical film, which has excellent optical compensation and stress relaxation properties without changing main properties such as endurance reliability and workability under a high temperature and/or high humidity condition to minimize a light leakage phenomenon caused by stress concentration of a protective film, and an optical member and a liquid crystal display device which include a pressure-sensitive adhesive layer manufactured using the same.

Pressure-sensitive adhesive composition

The present application relates to a pressure-sensitive adhesive composition, an optical laminate, a pressure-sensitive adhesive polarizing plate and a display device. In the present application, a pressure-sensitive adhesive composition having all excellent physical properties such as endurance reliability and interface adhesiveness and being capable of minimizing light leakage occurring under high temperature or high-temperature and humidity conditions can be provided. The pressure-sensitive adhesive composition of the present application can be used for an optical film such as a protective film and a polarizing plate.

A pressure-sensitive adhesive composition, which may have excellent durability under high temperature or humidity conditions and exhibit high close adhesion to optical films, thereby forming a pressure-sensitive adhesive having superior cuttability and re-workability, is provided. Also, a pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive capable of effectively inhibiting bending when applied to a thin substrate such as a very thin glass substrate, minimizing a time required to stabilize physical properties, and preventing a degradation of the secured physical properties in time, a pressure-sensitive adhesive optical member formed using such a pressure-sensitive adhesive composition, an optical laminate, and a display device are provided.

The present invention relates to a pressure-sensitive adhesive composition, an optical member, a polarizing plate, and a display device. The pressure-sensitive adhesive composition according to an embodiment of the present invention may form a pressure-sensitive adhesive which has excellent general physical properties such as coating properties, endurance reliability, or the like, and which may stably maintain the physical properties for the long term. Further, the pressure-sensitive adhesive composition may be particularly applied to various optical films, thereby forming the pressure-sensitive adhesive layer which exhibits excellent adhesion with the optical film, and when the pressure-sensitive adhesive composition is applied to the polarizing plate, bending properties may be effectively prevented.

Pressure sensitive adhesive composition

Provided are a pressure-sensitive adhesive optical film, a crosslinkable composition, and a display device. A pressure-sensitive adhesive layer using a polymer component exhibiting excellent crosslinking efficiency even at a low molecular weight to exhibit excellent workability, durability and dimension stability, and the optical film to which such a pressure-sensitive adhesive layer is applied may be provided.

Optical film

A block copolymer, a method for preparing a block copolymer, a resin composition, and a film are provided. The block copolymer can be useful in inhibiting complete separation of the hard segment even under a severe high-temperature condition by increasing the chemical cross-linking density around the hard segment without causing an increase in glass transition temperature of the hard segment, thereby maintaining high-temperature durability.

Block copolymer

The present applicant relates to a pressure-sensitive adhesive composition, and optical laminate, a polarizing plate, and a display device. In an embodiment of the present applicant, the pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive which has an excellent cohesive force or stress relaxation property, and thus has superior endurance reliability and light leakage suppression performance or the like may be provided. The pressure-sensitive adhesive composition according to an embodiment of the present applicant may be used, for example, for an optical film such as a polarizing plate or the like.

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.
