Abstract:
A laminated film having a support and a backcoat film containing a silicon-containing resin, a matting agent and a surfactant wherein the silicon-containing resin contains a condensate of a tetrafunctional alkoxysilane and a trifunctional or bifunctional alkoxysilane in a molar ratio of 25/75 to 85/15, a volume average particle diameter of the matting agent is bigger than an average thickness of the backcoat film, and a content of inorganic fine particles in the backcoat film is 20% or less, can suppress generation of iridescent unevenness, luminance decrease and surface irregularity.
Abstract:
A prism sheet as an optical functional sheet is a multilayer sheet, and includes a prism layer as an optical functional layer containing an organic material and a multilayer film. The multilayer film includes a film base and a first adhesive layer provided on the film base. The prism layer is formed on the first adhesive layer in a subsequent process. The thickness of the first adhesive layer is at least 0.1 μm. The first adhesive layer contains at least 10 mass % of polyolefin.
Abstract:
A laminated film including a support; an optical functional layer on A surface side of the support and condenses or diffuses incident light; and a hard coat layer of at least 150 nm thick which is provided on the outermost layer of B surface side that is opposite to the A surface side of the support and has an inorganic component formed of a hydrolyzate of alkoxysilane or a UV curable resin as a main component, has excellent brightness. The hard coat layer has high hardness and the adhesiveness between the hard coat layer and a support is excellent.
Abstract:
A sheet for illumination including a support, a mat layer which is arranged on one surface of the support, and an easily-adhesive layer which is arranged on the other surface of the support, in which a transmission value in percentage of image clarity in comb teeth with an interval of 2 mm and an image clarity value in percentage of reflection at 60° in comb teeth with an interval of 2 mm when an angle between a traveling direction of light and a normal of a sheet is set to be 60° satisfy (Transmission value in percentage of image clarity)/(image clarity value in percentage of reflection at 60°)≧2, suppresses reflection of external light without degrading sharpness of a printed image.
