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%≤()/()×100<30%  (2), and0≤()≤()<0.5 μm  (3);and the unreacted (meth)acryloyl groups of the coating layer of the heated sample irradiated with a prescribed amount of active energy rays have disappeared 10 to 100% as compared with the coating layer of the unheated sample.

Laminated member for decoration and method for producing decorative molded article

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.

Layered film and layered member

An object of the present invention is to provide a method for forming an antiglare hard coat layer having a concavo-convex shape that exhibits a good antiglare property and being superior in scratch resistance.

Method for forming anti-glare hard coat layer

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 &#x3bc;m or more and 600 &#x3bc;m 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&#xb0; C. is 50% or more.

Method for manufacturing layered film, and method for manufacturing layered member

An optical laminated member having an antiglare hard coat layer and a clear hard coat layer sequentially laminated on at least one side of a transparent polymer substrate, the antiglare hard coat layer being a cured layer of a coating composition for forming an antiglare layer and having continuous random irregularities on its surface, and a ten-point average roughness Rzof a surface of the antiglare hard coat layer is 0.1 to 2 &#x3bc;m, the clear hard coat layer is a cured layer of a clear hard coating composition, the clear hard coat layer is laminated on a part of the antiglare hard coat layer.
