Abstract: A transparent conductive laminate includes a transparent substrate, a first transparent conductive film formed on the transparent substrate, and a second transparent conductive film formed on a surface of the first transparent conductive film opposite to the transparent substrate. The first transparent conductive film includes a material selected from an oxide of indium, an oxide of zinc, an oxide of tin, and combinations thereof. The second transparent conductive film includes diindium trioxide (In2O3) and titanium dioxide (TiO2).

Abstract: A transparent conductive laminate for a semiconductor device includes a substrate, first and second refracting films, and a transparent conductive film formed on the second refracting film and having a pattern defined by etched and non-etched regions. The optical thicknesses of the first and second refracting films are controlled to reduce a difference between CIE b* color values produced in the etched and non-etched regions. The CIE b* color values are smaller than 1.15, and the differential value therebetween is less than 0.35 so that the pattern of the transparent conductive film can be obscured or hidden, thereby improving color homogeneity. A method of improving color homogeneity of the laminate is also disclosed.

Abstract: A transparent conductive layered structure for a touch panel input device includes: a substrate; and a layered conductor which includes a transparent first conductive layer formed on the substrate and including a film of conductive polymer, and a second conductive layer formed on the first conductive layer opposite to the substrate and including a conductive metal and/or metal compound. The second conductive layer has a conductivity larger than that of the first conductive layer.

Abstract: A polymerizable optical composition includes first and second monomers. The weight ratio of the first monomer to the second monomer is from 1:9 to 9:1. The second monomer contains at least one acryl functional group. The first monomer is represented by a formula [A]: wherein R1 is selected from one of O and S atoms; R2 is a bivalent functional group of (C2H4O)n, where n is an integer from 1 to 10; and R3 is selected from one of H and CH3.
