ADHESIVE FOR LAMINATING OPTICAL FUNCTIONAL FILM, OPTICAL FUNCTIONAL FILM WITH ADHESIVE AND METHOD FOR MANUFACTURING THE SAME

摘要

An adhesive for laminating optical functional films is provided to realize excellent durability in adhesion even under high-temperature and high-humidity conditions, and to prevent the generation of light leakage in an image display device. An adhesive for laminating optical functional films is obtained by irradiating active energy beams to an adhesive material comprising (A) an acrylic polymer containing more than 0.5 wt% of carboxyl group-containing monomers based on the weight of the total monomers, and (B) an active energy beam-curable compound. The adhesive has a maximum shear load of greater than 50N within a deformation ratio of 4000%, as measured at a shear rate of 0.1 mm/min after being laminated to alkali-free glass with an adhesion area of 100 mm^2(10 mmX10 mm). Also, the adhesive has a storage modulus(G') of 0.3-15 MPa at 23 deg.C.
