OPTICAL FILM HAVING ADHESIVE AGENT, AND OPTICAL LAMINATED BODY IN WHICH SAME IS USED

摘要

The present invention provides an optical film having an adhesive agent, the optical film being provided with an adhesive agent layer obtained using a composition in which 0.3 to 12 parts by weight of an ionizable compound and 0.1 to 5 parts by weight of a cross-linking agent are compounded with 100 parts by weight of an acrylic copolymer of a monomer mixture comprising 80 to 96 wt% of (A-1), 1 to 15 wt% of (A-2), 0.1 to 5 wt% of (A-3), and 0.5 to 5 wt% of (A-4). (A-1) is a compound of formula (I) (R1 is a hydrogen or methyl, and R2 is a C1-14 alkyl), (A-2) is an unsaturated monomer having an aromatic ring, (A-3) is a compound of formula (II) (R3 is a hydrogen or methyl, R4 is an alkyl, and m is 1 to 8), and (A-4) is an unsaturated monomer having a polar functional group.
