Definitions

  • the production method of the copolymer is not particularly limited, and may be prepared using a method such as bulk polymerization, solution polymerization, emulsion polymerization or suspension polymerization, which are commonly used in the art, and solution polymerization is preferable.
  • a solvent, a polymerization initiator, a chain transfer agent for molecular weight control, and the like, which are usually used in the polymerization may be used.
  • Such additives can be appropriately adjusted in a range not impairing the effects of the present invention.
  • the pressure sensitive adhesive polarizing plate was cut into 90 mm x 170 mm, and the release film was peeled off, and then attached to both surfaces of the glass substrate (110 mm x 190 mm x 0.7 mm) so that the absorption axes of the polarizing plates were perpendicular to each other.
  • the applied pressure was 5kg / cm 2 to prepare a specimen by performing a clean room operation so that no bubbles or foreign matter.
  • the heat resistance of the specimen was observed for 1000 hours at a temperature of 80 °C after the occurrence of bubbles or peeling. Immediately after evaluating the state of the specimen was performed at room temperature for 24 hours. In addition, the moisture resistant heat resistance of the specimen was observed for 1000 hours at a temperature of 60 °C and humidity conditions of 90% RH after the presence of bubbles or peeling.
  • the polarizing plate was cut out to a width of 25 mm and a length of 100 mm, the release film was peeled off, and then laminated to Corning's # 1737 glass at a pressure of 0.25 MPa, and the autoclave was treated at 5 atmospheres and 50 ° C. for 20 minutes. Evaluation samples were prepared. After putting it in an oven at 80 ° C., which was heat-resistant, it was taken out after 10 hours, left at room temperature for 120 hours, and then peeled at a speed of 1.3 cm / s.

Abstract

La présente invention concerne une composition acrylique adhésive et plus spécifiquement, une composition acrylique adhésive contenant un composé à base de silane comportant un groupement NCS et présentant ainsi une excellente adhérence initiale, ce qui permet de réduire le défaut de détachement d'une plaque polarisante provoqué par l'eau (humidité), et qui présente une excellente durabilité d'adhésion en conditions extrêmes (température élevée ou température et humidité élevées), et dont l'adhérence n'augmente pas excessivement même dans des conditions de températures élevées ou de température et d'humidité élevées, ce qui permet de ne laisser aucun résidu d'adhésif sur un matériau de base lors de détachement.
