TRIACETYLCELLULOSE LAMINATED BODY, AND OPTICAL FILM AND OPTICAL MEMBER USING THE SAME

PROBLEM TO BE SOLVED: To provide a laminated body capable of relaxing a contraction stress of a triacetylcellulose (TAC) substrate and preventing the floating from a glass substrate without using a peroxide even in a high-temperature and high-humidity environment when the TAC substrate and the glass substrate are laminated via a pressure-sensitive adhesive layer.SOLUTION: The laminated body includes the pressure-sensitive adhesive layer 12 formed on the TAC substrate 11, the pressure-sensitive adhesive layer 12 comprising an acrylic type pressure-sensitive adhesive, an isocyanate type curing agent and an acrylic copolymer, wherein a loss tangent at 60°C of the pressure-sensitive adhesive layer 12 is 0.35 or more and is less than 1.0 and a loss tangent at 80°C is 0.40 or more and is less than 1.0. The isocyanate type curing agent is preferably a hexamethylene diisocyanate type and the acrylic copolymer is preferably an M-A-M type triblock copolymer which comprises a methyl methacrylate polymer block (M) and a butyl acrylate polymer block (A) and has a weight-average molecular weight of 10, 000 to 300, 000.
