The present invention relates to an optical adhesive film including plate-type inorganic nanoparticles and a curable resin. The optical adhesive film has improved barrier characteristics to moisture and gas, improved light-transmittance, and excellent durability and peel characteristics.

Optical adhesive film, method for manufacturing optical adhesive film and touch screen panel comprising same

Provided is a urethane adhesive composition for a touch panel having a glass transition temperature between &#x2212;20&#xb0; C. to &#x2212;50&#xb0; C., and which, as a cured composition, has an elasticity of 50,000 Pa to 70,000 Pa at 60&#xb0; C. to 80&#xb0; C.

Adhesive composition for touch panel, adhesive film, and touch panel

Provided are an adhesive composition for a touch panel, including: a hydrophilic functional group-containing monomer and an adhesion promoter, wherein a dielectric constant at a frequency of 100 kHz to 2 MHz is 3.5 or less, and a storage modulus is 1.0&#xd7;10Pa to 7.0&#xd7;10Pa at 25&#xb0; C. to 85&#xb0; C., and an adhesive film including an adhesive layer including a cured product of the adhesive composition for a touch panel. In addition, provided is a touch panel including: a conductive plastic film having a conductive layer formed on one surface; and an adhesive layer attached onto the conductive layer and including a cured product of the adhesive composition for a touch panel.

Adhesive composition for touch panel, adhesive film and touch panel

The present invention relates to an optical adhesive film which has excellent adhesive strength at room temperature and has improved efficiency in a rework process since peel strength is low at high temperatures. When attaching a touchscreen panel and an LCD by using the adhesive film of the present invention and separating the touchscreen panel and the LCD at high temperatures, the touchscreen panel and the LCD can be separated from each other without causing damage thereto. Additionally, the optical film of the present invention comprises two adhesive layers, wherein peeling occurs at the first adhesive layer having an adhesive composition such that a peeling surface can be controlled according to the convenience of a user.
