ADHESIVE AGENT COMPOSITION FOR OPTICAL FILM AND PROCESSED PRODUCT OF THE SAME

WIPO Patent Application WO/2012/105358

A1

An object of the invention is to provide an adhesive agent composition for an optical film with which peeling and bubbling are prevented even when the optical film is set aside under high-humidity and high-temperature conditions after adhesion, the item to which the film adheres remains unstained even if re-peeling of the film becomes necessary, the adhesive agent composition responds to the stress that is generated with dimensional changes in the optical film and discoloration associated with exposure to light is thereby controlled, and it is possible to prevent wrinkling and indentation when the optical film is taken up in a roll. Another object is to provide an optical film that uses the adhesive agent composition. The adhesive agent composition for an optical film is characterized in being obtained by adding 4 to 20 parts by weight of an isocyanate crosslinking agent per 100 parts by weight of an acrylic polymer that contains 8 to 35 parts by weight of an aromatic ring-containing acrylic monomer and 1 to 12 parts by weight of an amide group-containing acrylic monomer as the structural monomers. The optical film is characterized in that an adhesive agent layer obtained from the adhesive agent composition is disposed on at least one surface of the film.
