Abstract: A hardcoat for a plastic substrate film is provided which has good suitability for printing and satisfactory hardness, can prevent influence of the deformation of a plastic substrate film from extending to the hardcoat, and is resistant to cracking and peeling. The hardcoat is produced from a coating component containing one or more organic components having a polymerizable functional group and an inorganic filler, at least one of the organic components being free from a hydrogen bond-forming group. In the hard coat, the content of the inorganic filler in the surface of the hardcoat is higher than that in the interior of the hardcoat. The hardcoat can be applied to antireflection films and hologram labels.

Abstract: The present invention provides a gas barrier film comprising a composite film provided with a gas barrier layer having a laminated structure including at least a metal oxide thin layer on a substrate film having a (1) 80 ppm/° C. or less coefficient of thermal expansion at 50° C. to 150° C. and/or a 10 ppm/% RH or less coefficient of humidity expansion at 25° C., and a (2) 150 C. ° or more glass transition temperature, and a display with a display element covered with the same.

Abstract: A antiglare layer 12 having a fine uneven surface is formed directly or through other layer(s) on a transparent substrate film 11, and a layer 13 having a low refractive index, which is lower than the refractive index of the antiglare layer 12, is formed thereon. The refractive index of the antiglare layer 12 is higher than the refractive index of a layer in contact with said antiglare layer 12 on its surface remote from the layer 13 having a low refractive index. An SiOx film may be used as the layer 13 having a low refractive index. The SiOx film per se has excellent gas barrier property and antifouling property as an optical functional membrane and is an optical functional material characterized by having excellent moistureproofness, scratch resistance, adhesion to a substrate, transparency, low refractive index, dye deterioration preventive property, and other properties.
