PROBLEM TO BE SOLVED: To provide a method for producing a sunbeam shielding material in which sunbeam transmission is low and haze value is also low even in a region where visible light transmission is as high as≥80%, to provide a sunbeam shielding material, to provide a coating liquid for forming a sunbeam shielding film, and to provide a sunbeam shielding film. SOLUTION: The fine particles of a sunbeam shielding material 9 are obtained by performing the dropping 13 of an alkaline solution 5 into a raw material mixed solution 4 obtained by mixing 11 an aqueous solution of a tin compound 1, an aqueous solution of an indium compound 2 and an aqueous solution of a rhenium compound 3 for 25 min while carrying out stirring under the control at 20°C, then, performing stirring 12 for 10 min to cause aging 14 so as to obtain coprecipitated matter 6, then subjecting the precipitated matter to washing 15 and drying 16 into indium-tin-rhenium hydroxide 7, further, subjecting the same to heating 18 while performing stirring 17 in a reducing gas-inert gas atmosphere 8, and carrying out reduction treatment. The coating liquid for forming a sunbeam shielding film is obtained by dispersing the fine particles into a solvent together with a binder and a hardening agent. COPYRIGHT: (C)2005,JPO&NCIPI
