Abstract:
An optical layered film includes at least one A layer including a thermoplastic resin [A] and a B layer formed of a thermoplastic resin [B], wherein the at least one A layer is provided on at least one of surfaces of the B layer, a thickness-direction retardation Rthb of the B layer satisfies the following formula (1), and a tensile elongation at break Sa of a 1.5 mm-thick film (a1) formed of the thermoplastic resin [A] satisfies the following formula (2): (1) |Rthb|≤40 nm, and (2) Sa≤100%.
Abstract:
A multilayer optical film including: an A layer formed of an alicyclic structure-containing polymer resin; and a B layer disposed on at least one surface of the A layer to be in direct contact therewith, the B layer serving as a masking layer, wherein the B layer is a cured product of a material Y including a dispersion of a crosslinkable polymer (a) and solid particles (b), and the B layer has a thickness tB of 10 μm or more and 25 μm or less; and a production method including the steps of applying the material Y onto a surface of the A layer, to form a layer of the material Y; and curing the layer of the material Y.
