    摘要： An electrolyte composition contains a propane sultone compound substituted with a specific substituent, a cyclic fluorocarbonate-based compound and a nonaqueous solvent. A secondary battery containing the electrolyte composition is disclosed. The electrolyte composition has excellent SEI film-forming ability and HF-removing ability by containing the cyclic fluorocarbonate-based compound together with the propane sultone compound substituted with a specific substituent, so that the lifespan characteristic and stability at high temperature can be improved.

    摘要： Provided is an adhesive composition whose initial adhesive strength (A) and adhesive strength at increased temperature (B) satisfy a ratio (B/A) of 2.0 or lower, wherein the (A) value is measured through a peeling test after a sample is left for 24 hours at 23° C. and 50% relative humidity, and the (B) value is measured through a peeling test after a sample is left for 48 hours at 50° C. and 50% RH; the sample is prepared by laminating an adhesive-attached polarizing plate having a size of 25 mm×100 mm on a substrate at a pressure of 0.25 MPa and treating the laminate in an autoclave, the adhesive being formed from the adhesive composition; and the peeling test is performed by peeling the adhesive from the glass substrate at a peeling rate of 300 mm/min and a peeling angle of 180° using a universal testing machine.

    摘要： An adhesive composition includes an acryl copolymer having a carboxyl group, and a silane compound represented by Formula 1 or 2, thereby it is possible to exhibit excellent initial adhesiveness and adhesive durability under severe conditions, and prevent the substrate from being torn due to a decrease in adhesiveness by water applied thereto, and the adhesive from remaining on the substrate during peeling-off the adhesive layer, as well as after drying, the adhesive layer may exhibit favorable adhesiveness again, thus being used for re-bonding.
