  • Publication number: 20240091998
    Abstract: Provided is an after-cure type laminated film having a low reflectance. 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 an optical interference layer, the transparent support substrate has a thickness of 50 ?m or more and 600 ?m or less, a stretch ratio of the laminated film at 160° C. is 50% or more, and the laminated film heat-treated at a temperature of 90° C. for 30 minutes has a minimum value RAH of a reflectance taken between wavelengths of 380 nm and 780 nm of 2% or less and measured from a side of the uncured optical interference layer.
