摘要： Provided is a method for manufacturing a laminated film that can be molded into a complicated shape. A method for manufacturing a laminated film comprising: a step of forming an uncured hard coat layer by applying an active energy-ray curable composition for forming a hard coat layer to one side of a first support substrate having a thickness of 50 μm or more and 600 μm or less, and then drying the composition; a step of forming an uncured optical interference layer by applying an active energy-ray curable composition for forming a optical interference layer on one surface of a second support substrate so that the thickness of the uncured optical interference layer is between 15 nm or more and 200 nm or less, and then drying the composition; and a lamination step of laminating a surface of the uncured hard coat layer opposite the first support substrate and a surface of the uncured optical interference layer opposite the second support substrate to obtain a laminated film, wherein a stretch ratio of the laminated film at 160° C. is 50% or more.

摘要： Provided is a laminated film that can be molded into a complicated shape. A laminated film comprising a transparent support substrate; an uncured hard coat layer formed on at least one surface of the transparent support substrate; and an uncured optical interference layer formed on the uncured hard coat layer, wherein the uncured hard coat layer comprises an active energy ray-curable composition for forming a hard coat layer, the uncured optical interference layer comprises an active energy ray-curable composition for forming a optical interference layer, a thickness of the transparent support substrate is 50 μm or more and 600 μm or less, a luminous reflectance including regular reflected light measured from an uncured optical interference layer side is 0.1% or more and 4.0% or less, and a stretch ratio at 160° C. is 50% or more.
