Definitions

  • the present invention relates to an optical film, a polarizing plate, and an image display device.
  • an optical film in which a functional layer (surface treatment layer) such as a hard coat layer, an antiglare layer, or an antireflection layer is formed on one side of a base film made of an acrylic resin is known (Patent Document 1). .
  • the surface treatment layer can be formed by applying the resin composition to one side of the base film and drying or curing.
  • Such an optical film can be used as, for example, a protective film for a polarizer or a front plate of an image display device.
  • the light transmittance at 380 nm when the thickness of the base film is 30 ⁇ m is preferably as high as possible. Specifically, the light transmittance is preferably 85% or more, more preferably 88% or more, and further preferably 90% or more. If the light transmittance is within such a range, desired transparency can be ensured.
  • the light transmittance can be measured, for example, by a method according to ASTM-D-1003.

Abstract

L'invention concerne un film optique présentant une excellente adhérence entre un film de substrat et une couche traitée en surface. Le film optique comprend un film de substrat, qui est un film étiré contenant une résine acrylique, et un film traité en surface formé sur un côté du film de substrat. Le film de substrat dans le film optique a un taux de changement dimensionnel de 2,0 % à 0 % après avoir été laissé reposer à 100 °C pendant 120 heures dans un état dans lequel 10 cm x 10 cm du film de substrat ont été découpés et collés à une plaque de verre au moyen d'un adhésif.
