LAMINATED FILM-EQUIPPED TRANSPARENT SUBSTRATE, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a laminated film-equipped transparent substrate which is suitably used as a single sheet in a heat zone of low latitude to middle latitude and has excellent durability in addition to high heat shielding properties and high color rendering properties, and to provide a method for producing the laminated film-equipped transparent substrate.SOLUTION: The laminated film-equipped transparent substrate has a transparent substrate and a laminated film formed by stacking a transparent electroconductive layer and a nitrogen-containing optical absorption layer having 10 nm or larger thickness. The method for producing the laminated film-equipped transparent substrate comprises: a coating step of forming a precursor layer of the transparent electroconductive layer and another precursor layer of the nitrogen-containing optical absorption layer on the transparent substrate by a coating method, which precursor layers will become the transparent electroconductive layer and the nitrogen-containing optical absorption layer respectively by heat treatment, to obtain the coated transparent substrate; and a heat treatment step of heat-treating the coated transparent substrate for 1-30 minutes at 550-750°C in the atmosphere or for 15 minutes to 4 hours at 150-450°C in the atmosphere.SELECTED DRAWING: Figure 2
