Patent ID: 10384423

Abstract:
A heat-ray shielding lamination structure composed of two laminated plates of plate glass, plastic, or plastic containing particles having a heat-ray shielding function and metal compounds, interposing an interlayer containing particles having a heat-ray shielding function and metal compounds, wherein the particles are composite tungsten oxide particles of formula MYWOZ (0.001≤Y≤1.0, 2.2≤Z≤3.0), wherein M is at least one of Cs, Rb, K, and Tl, having a hexagonal crystal structure, with a particle size between 1 and 800 nm, the metal compounds are metal salts of carboxylic acids, metal carbonates, metal carbonate hydroxides, or metal hydroxides, and are contained in an amount between 1 pts.wt. and 100 pts.wt. based on 100 pts.wt. of the composite tungsten oxide particles.
