PROBLEM TO BE SOLVED: To provide a high performance optical laminated sheet with each layer of the laminated sheet capable of exerting its roll maximally, by strongly bonding an inorganic moisture-proof layer and a cured hardening resin layer formed thereon. SOLUTION: An optical laminated sheet comprises a substrate film 1, an organic air-proof layer 2, an inorganic moisture-proof layer 3, and a cured hardening resin layer 4. The cured hardening resin layer 4 is formed on the inorganic moisture-proof layer 3 via an anchor coating layer(AC). The anchor coating layer(AC) comprises a modified polyester film layer having 40% by weight or more of the isophthalic acid unit among the carboxylic acid component comprising the polyester, a 80 deg.C or less glass transition point, a 5,000 to 60,000 molecular weight, and a functional group. The modified polyester is used for forming the anchor coating layer(AC) in the form of a composition. |
