Definitions

  • the release film is peeled off from the pressure-sensitive adhesive layer of the polarizing film with the pressure-sensitive adhesive layer. Static electricity is generated.
  • the static electricity generated in this way affects the orientation of the liquid crystal inside the liquid crystal display device, leading to defects. Further, display unevenness due to static electricity may occur when the liquid crystal display device is used.
  • the generation of static electricity can be suppressed, for example, by forming an antistatic layer on the outer surface of the polarizing film, but the effect is small and there is a problem that static electricity generation cannot be fundamentally prevented.
  • the pressure-sensitive adhesive composition may further contain a crosslinking agent.
  • the crosslinking agent (C) is preferably contained in an amount of 0.01 to 20 parts by weight with respect to 100 parts by weight of the (meth) acrylic polymer (A).
  • the crosslinking agent (C) is preferably at least one selected from an isocyanate compound and a peroxide.
  • an antistatic function can be imparted by adding an ionic compound to the adhesive.
  • the antistatic function is efficiently expressed by bleeding out of the ionic compound on the surface of the pressure-sensitive adhesive layer.
  • optical characteristics such as the degree of polarization may be deteriorated.
  • the isocyanate-based crosslinking agent may be used singly or as a mixture of two or more, but the total content thereof is the (meth) acrylic polymer (A) 100
  • the polyisocyanate compound crosslinking agent is preferably contained in an amount of 0.01 to 2 parts by weight, more preferably 0.02 to 2 parts by weight, and more preferably 0.05 to 1.5 parts by weight. More preferably, it is contained in parts by weight. It can be appropriately contained in consideration of cohesive force and prevention of peeling in a durability test.
  • the drying time is preferably 5 seconds to 20 minutes, more preferably 5 seconds to 10 minutes, and particularly preferably 10 seconds to 5 minutes.
  • the staining solution uses water as a solvent, and an iodine concentration within the range of 0.12 to 0.30% by weight and a potassium iodide concentration within the range of 0.7 to 2.1% by weight.
  • concentration ratio of iodine and potassium iodide is 1 to 7.
  • potassium iodide is required to dissolve iodine in water.
  • the stretched laminate is immersed for 60 seconds in a dyeing solution having an iodine concentration of 0.30% by weight and a potassium iodide concentration of 2.1% by weight. A colored laminate is adsorbed on the substrate.

Abstract

Le film polarisant avec couche adhésive de l'invention possède un film polarisant, et une couche adhésive agencée sur celui-ci. Ledit film polarisant possède un film protecteur transparent d'un seul côté d'un polariseur. Ladite couche adhésive est agencée sur ce polariseur du côté exempt dudit film protecteur transparent. Ladite couche adhésive est formée à partir d'une composition d'adhésif comprenant un polymère (méth)acrylique (A) et un sel d'anion imide fluoré - onium (B). Le film polarisant avec couche adhésive possède une couche adhésive dotée d'une fonction prévention de charge statique et satisfaisante en termes de durabilité, et la dégradation de ses caractéristiques optiques sont faibles.
