  • Publication number: 20140300979
    Abstract: To provide a half mirror front plate which has luminous transmittance and luminous reflectance enough to function as a half mirror for display, provides color tones of transmitted light and reflected light close to neutral (visually white), and is excellent in productivity. A half mirror front plate for display includes a stack consisting of a transparent substrate and a half mirror stacked film arranged on one principal surface of the transparent substrate, wherein the half mirror stacked film has a first transparent oxide layer with a thickness of 45 nm to 70 nm made of a first metal oxide, a metal layer with a thickness of 30 nm to 45 nm mainly made of silver, and a second transparent oxide layer with a thickness of 45 nm to 70 nm made of a second metal oxide in order from the transparent substrate side.

  • Publication number: 20140079927
    Abstract: A material for a conductive film 1 contains a transparent base material 2, an underlayer 3, a first amorphous layer 4, and a second amorphous layer 5. The first amorphous layer 4 is laminated on the transparent base material 2 and is made of an indium tin oxide containing from 2 to 15 mass % of tin as calculated as its oxide. Further, the second amorphous layer 5 is laminated on the first amorphous layer 4 and is made of an indium tin oxide containing from 2 to 15 mass % of tin as calculated as its oxide. The content of tin as calculated as its oxide in the second amorphous layer 5 is different from the content of tin as calculated as its oxide in the first amorphous layer 4.

  • Publication number: 20130302580
    Abstract: To provide a laminated glass having a high infrared reflecting performance while retaining a reflected color to be neutral, and a process for producing such a laminated glass. The laminated glass of the present invention comprises two glass sheets, and an interlayer and a laminate having a heat ray reflecting function, interposed between the two glass sheet, wherein a high refractive index film is provided between the two glass sheets besides films that constitute the laminate having a heat ray reflecting function. The high refractive index film has a refractive index of at least 1.90 at a wavelength of 550 nm and contains at least any one of titanium oxide, zinc oxide, tantalum oxide, zirconium oxide, niobium oxide, tin oxide, titanium nitride, silicon nitride, zirconium nitride, aluminum nitride, titanium oxynitride, zirconium oxynitride and tin oxynitride.

  • Publication number: 20100171406
    Abstract: To provide an electroconductive laminate which has a broad transmission/reflection band and which is excellent in electrical conductivity (electromagnetic wave shielding properties), visible light transmittance, visible light antireflection properties, near infrared shielding properties and moisture resistance, and an electromagnetic wave shield for a plasma display employing such a laminate. An electroconductive laminate 20 comprising a substrate 21 and an electroconductive film 22 formed on the substrate 21, wherein the electroconductive film 22 has a multilayer structure having a high refractive index layer (23a to 23e) and a metal layer (24a to 24d) alternately laminated in this order from the substrate side in a total number of 2n+1 layers (wherein n is an integer of from 1 to 12) and further having a hydrogenated carbon layer 25 at a position most removed from the substrate 21; the refractive index of the high refractive index layer (23a to 23e) is from 1.5 to 2.
