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

摘要

A coating solution which forms a heat-ray shielding film on a transparent base of glass or plastic includes a dispersion obtained by dispersing in a dispersion medium as its main component fine particles of one or more oxides selected from the group consisting of ruthenium-, iridium- and rhodium-containing oxides, the particles having an average particle diameter of 100 nm or less.
