Definitions

  • the adhesion promoting layer is a photocurable having a semi-unggi group capable of hydrogen bonding It contains cured resin of a monofunctional monomer.
  • the photocurable monofunctional monomer having a hydrogen bondable reactor is less evaporated than a solvent, and has good reactivity and can be eroded on the substrate regardless of the characteristics of the substrate. Such substrate erosion enables chemical bonding between the substrate layer and the adhesion promoting layer after the substrate erosion, and thus it is possible to maintain excellent adhesion regardless of the characteristics of the substrate, even if no additional adhesive or crosslinking agent is included.
  • the curable resin when the curable resin is a curable resin of a photocurable monofunctional monomer having a reactor capable of hydrogen bonding and a polyfunctional acrylate monomer, the photocurable monofunctional having a semi-ungung capable of hydrogen bonding.
  • the polyfunctional acrylate monomer may be cured at about 10 to about 150 parts by weight based on about 100 parts by weight of the total monomer.
  • the polarizer protective film of the present invention may have sufficient flexibility and adhesion without deterioration of physical and optical properties.
  • the irradiation amount of ultraviolet rays in the curing process may be, for example, about 20 to about 600mJ / cm 2.
  • a light source of ultraviolet irradiation this technology belongs There is no particular limitation as long as it can be used in the art, and for example, a high pressure mercury lamp, a metal halide lamp, a black light fluorescent lamp, or the like can be used.
  • the polarizer protective film of the present invention as described above is applied to the substrate a resin composition comprising the photocurable monofunctional monomer, the polyfunctional acrylate monomer, the polyfunctional acrylate polymer, inorganic fine particles, a photopolymerization initiator, and a solvent. After curing, it can be formed.

Abstract

La présente invention concerne un film de protection pour polariseur, un procédé pour sa fabrication et une plaque polarisante comportant un film de protection pour polariseur. Plus particulièrement, la présente invention concerne un film de protection pour polariseur présentant non seulement d'excellentes caractéristiques physiques et optiques mais possédant également un excellent pouvoir d'adhérence, ainsi qu'une plaque polarisante comportant celui-ci. Un film de protection pour polariseur selon la présente invention et un plaque polarisante comportant celui-ci présentent un haut degré de dureté, un haut degré de transparence et un haut degré de résistance à l'abrasion, et peuvent prendre une forme compacts, ce qui leur confère une applicabilité étendue à divers types d'affichages.
