| titleOfInvention | Laminated optical film and manufacturing method thereof |
| abstract | Provided are a laminated optical film having excellent internal haze prevention properties and dimensional stability, and having appropriate retardation development properties, and a method for producing the same. A cellulose ester resin A layer, a cellulose ester resin B layer, and a thermoplastic resin C layer (referred to as “A layer”, “B layer”, and “C layer”, respectively) are divided into an A layer, a C layer, A laminated optical film formed by laminating a B layer, a C layer, and an A layer in this order, wherein the average acyl group substitution degree of the cellulose ester of the A layer is in the range of 2.8 to 3.0, and the B The average acyl group substitution degree of the cellulose ester of the layer is in the range of 1.0 to 2.5, and the thickness obtained by adding the two A layers sandwiching the B layer and the C layer is At, and the B layer is The total thickness of the sandwiched C layers is Ct, the thickness of the B layer is Bt, and the total layer thickness (At + Bt + Ct) is Tt. At, Bt, Ct, and Tt are specified. A laminated optical film characterized by satisfying the formula: [Selection figure] None |
