  • Publication number: 20100271699
    Abstract: The present invention provides a coating composition for antireflection that includes a) a low refractive material having a refractive index of 1.2 to 1.45, b) a high refractive material having a refractive index of 1.55 to 2.2 and comprising high refractive fine particles and an organic substituent, in which the difference in the surface energy between two materials is 5 mN/m or more; an antireflection film manufactured using the coating composition for antireflection; and a method of manufacturing the antireflection film. According to the present invention, the antireflection film having excellent antireflection characteristic can be manufactured by one coating process, thereby reducing manufacturing cost.

  • Publication number: 20100265580
    Abstract: The present invention provides a coating composition for antireflection that includes a low refractive material having a refractive index of 1.2 to 1.45 and a high refractive resin having a refractive index of 1.46 to 2, in which the difference in the surface energy between two materials is 5 mN/m or more; an antireflection film manufactured using the coating composition for antireflection; and a method of manufacturing the antireflection film. According to the present invention, the antireflection film having excellent abrasion resistance and antireflection characteristic can be manufactured using a single composition by one coating process, thereby reducing manufacturing cost.

  • Publication number: 20100009151
    Abstract: The present invention relates to a coating composition of a cycloolefin film that includes 100 parts by weight of an acrylate binder resin, 5 to 50 parts by weight of an olefin resin, 2 to 20 parts by weight of a photoinitiator, and 80 to 400 parts by weight of a solvent. The coating composition of the cycloolefin film may further include 1 to 20 parts by weight of fine particles having an average particle size in the range of 0.5 to 5 ?m. The coating composition may be used as a hard coating composition and a dazzling prevention coating composition in respects to the cycloolefin film.
