Adhesive composition |
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. |

1. 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 initial adhesive strength (A) is measured through a peeling test after a sample is left for 24 hours at 23° C. and 50% relative humidity (RH), and the adhesive strength at increased temperature (B) 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 glass 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 (UTM). |
