摘要： An object of the present invention is to provide a laminated member for decoration that can be molded into a complicated shape and has a superior hardcoating property. The present invention relates to a laminated member for decoration having a protective film, a coating layer and a resin substrate, wherein the surface roughness Rz(a) of the adhesive layer of the protective film on the side where the coating layer is located and the surface roughness Rz(b) of the coating layer of an unheated sample formed by peeling the protective layer, the surface roughness being taken on the side opposite from the resin substrate, define Rz(b)/Rz(a)×100 having a prescribed relationship; the surface roughness Rz(b) and the surface roughness Rz(bh) of the coating layer of a heated sample prepared by heating the unheated sample under a prescribed condition, the surface roughness being taken on the side opposite from the resin substrate, satisfy at least one of Formulas (2) and (3) below: 0%≤Rz(bh)/Rz(b)×100

摘要： 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 μm or more and 600 μm 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.

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.
