Abstract

The laminated film includes a substrate film; and a cured layer obtained by curing a polymerizable composition includes a compound having a cyclic ether group, a polyfunctional (meth)acrylate compound having three or more (meth)acryloyl groups in one molecule, a radical polymerization initiator, and a cation polymerization initiator, in which an absorbance ratio P1/P2 in an infrared absorption spectrum of the cured layer is in a range of 4.40 to 15.00, and an absorbance ratio P2/P3 is in a range of 0.01 to 0.08, P1 is an absorbance at an absorption maximum peak in a wave number range of 3,650 to 3,200 cm, P2 is an absorbance at an absorption maximum peak in a wave number range of 800 to 770 cm, and P3 is an absorbance at an absorption maximum peak in a wave number range of 1,740 to 1,690 cm.
