Coating solution for a heat-ray shielding film and a process for forming a heat-ray shielding film by employing the same

摘要

This invention relates to a coating solution for a heat-ray shielding film which can form on a transparent base of glass, plastics, etc. a heat-ray shielding film showing a high heat-ray shielding effect without lowering its transmittance of visible light, and to a process for forming a heat-ray shielding film by employing it, and provides a coating solution for a heat-ray shielding film which comprises a dispersion obtained by dispersing in a dispersion medium as its main component fine particles having an average particle diameter of 100 nm or less, of one or more oxides selected from the group consisting of ruthenium-, iridium- and rhodium-containing oxides, and a process for forming a film thereof.
