Abstract: The present invention relates to an epoxy resin composition, an adhesive film and an adhesive tape with excellent storage stability under room temperature. By adding a liquid type latent curing agent instead of a general heat-curing agent to a conventional adhesive composition, since the adhesive film or the adhesive tape state in the semi-cured state also has excellent adhesion and heat resistance even after storage under room temperature for a long time of 90 days or more, it is possible to be variously applied in fields capable of storage under room temperature and requiring excellent physical properties, such as adhering and manufacturing of electrical devices.

Abstract: The present invention relates to an adhesive composition with adhesive strength variability and an adhesive film, which can be variously applied to fields requiring adhesive strength variability such as adhering and manufacturing of electric devices, by adding a UV curable oligomer resin to existing adhesives to exhibit excellent adhesive strength at the beginning and significantly reduce the adhesive strength after UV curing. The adhesive composition comprises a base Polymer; a crosslinking agent reacting with the base polymer; a curable resin to be UV-cured after the reaction between the base polymer and the crosslinking agent; and an initiator to cure the curable resin, wherein the curable resin includes a first oligomer, a second oligomer, and an organic acid.

Abstract: An adhesive film according to the present invention can be initially attached to a substrate with a low adhesive force to easily remove an unnecessary portion, and thereafter, the adhesive film may be strongly attached to the substrate by easily increasing the adhesive force of the remaining portion of the film. Particularly, the adhesive film of the present invention has a sufficiently low initial adhesive force, but has a sufficiently high final adhesive force, so that variability in the adhesive force is very excellent. Therefore, the adhesive film of the present invention and the adhesive composition for preparing the same may be usefully applied to a process requiring the variability in the adhesive force, such as manufacturing of an OLED display panel.
