Abstract: A process for producing a noble-metal type fine-particle dispersions, having the steps of an agglomeration step of adding a hydrazine solution to a dispersion in which primary particles of noble-metal type fine particles have been made to stand monodisperse in a solvent, to destabilize the dispersibility of the noble-metal type fine particles in the dispersion and cause the plurality of primary particles in the noble-metal type fine particles to agglomerate in the form of chains to obtain a dispersion of chainlike agglomerates; and a stabilization step of adding a hydrogen peroxide solution to the dispersion of the chainlike agglomerates obtained, to decompose and remove the hydrazine to stabilize the dispersibility of the chainlike agglomerates in the dispersion.

Abstract: The present invention pertains to a transparent conductive layered structure having a transparent substrate and a transparent 2-layer film consisting of a transparent conductive layer and a transparent coating layer formed in succession on this substrate, that is used for instance, in the front panel of displays, such as CRTs, etc. The above-mentioned transparent conductive layer has as its main components noble metal microparticles with a mean particle diameter of 1 to 100 nm composed of gold and/or platinum and silver and containing 5 to 95 wt % gold and/or platinum, colored pigment microparticles with a mean particle diameter of 5 to 200 nm, and binder matrix. The noble metal microparticles are mixed at a ratio of 1 to 40 parts by weight per 1 part by weight colored pigment microparticles. Moreover, it is characterized in that the transparent 2-layer film has a surface resistance of 10 to 5000 &OHgr;/□, reflectance of 0 to 2.
