Disclosed is a semi-hardened pressure sensitive adhesive film to be used in the semi-hardened state and having excellent printing step absorption properties. The adhesive film according to the present invention contains a radial polymer composition and a cationic polymer composition, and the radial polymer composition is primarily cross-linked to maintain the semi-hardened state. When applied onto a substrate through a printing step, the present invention has excellent step absorption properties and adhesion properties and excellent durability even under high-temperature and high-humidity conditions.

Semi-hardened pressure-sensitive adhesive film

A high-refractive adhesive film includes: a thermosetting resin matrix; and high refractive particles dispersed in the thermosetting resin matrix. The refraction index of the high-refractive particles is higher than that of the thermosetting resin matrix.

High-refractive adhesive film and touch panel including the same

The present invention provides an optical adhesive sheet including a layered structure of a first adhesive layer and a second adhesive layer, in which the first adhesive layer has a glass transition temperature of &#x2212;50&#xb0; C. to &#x2212;30&#xb0; C. and a modulus of 0.3&#xd7;10Pa to about 0.6&#xd7;10Pa, and the second adhesive layer has a glass transition temperature of &#x2212;20&#xb0; C. to &#x2212;10&#xb0; C. and a modulus of 0.7&#xd7;10Pa to 1.0&#xd7;10Pa.

Optical adhesive sheet
