摘要

PROBLEM TO BE SOLVED: To provide a heat-ray shielding lamination structure exhibiting excellent optical characteristics and excellent weather resistance by using composite tungsten oxide fine particles having excellent heat-ray shielding characteristics.SOLUTION: The heat-ray shielding lamination structure comprises: two laminated plates selected from plate glass, plastics, and plastics containing fine particles having a heat-ray shielding function and a metal salt of a carboxylic acid; and an intermediate layer containing fine particles having a heat-ray shielding function and a metal salt of a carboxylic acid, interposed between the above plates. The fine particles having a heat-ray shielding function are composite tungsten oxide fine particles. The lamination structure contains the metal salt of a carboxyl acid by 1 part by weight or more and 100 parts by weight or less with respect to 100 parts by weight of the composite tungsten oxide fine particles.SELECTED DRAWING: Figure 1
