Abstract
Official abstract text for this publication.
An infrared shielding film is an infrared shielding film including: an organic binder; and a plurality of tin-doped indium oxide particles (ITO particles) dispersed in the organic binder, in which the average center-to-center distance between adjacent particles of the ITO particles is in a range of 9 nm or more and 36 nm or less, the ratio of the average center-to-center distance between the adjacent particles to the average primary particle diameter of the ITO particles is in a range of 1.05 or more and 1.20 or less, and a roughness Ra of a film surface is in a range of 4 nm or more and 50 nm or less.
First claim
Opening claim text (preview).
What is claimed is: 1. An infrared shielding film comprising: an organic binder; and a plurality of tin-doped indium oxide particles dispersed in the organic binder, wherein the tin-doped indium oxide particles are produced using fatty acid salts of In and fatty acid salts of Sn, and surfaces of the tin-doped indium oxide particles are coated with an organic protective group derived from the fatty acid salts, the organic binder is one selected from the group consisting of (Z)-4-octenenitrile, (Z)-5-octenenitrile, (Z)-5-nonenenitrile, (Z)-6-undecenenitrile, (Z)-9-undecenenitrile, and (Z)-9-octadecenenitrile, an amount of the organic binder is in a range of 5 parts by mass or more and 30 parts by mass or less when an amount of the tin-doped indium oxide particles is 100 parts by mass, the tin-doped indium oxide particles are dispersed in a state of primary particles, an average center-to-center distance between adjacent particles of the tin-doped indium oxide particles is in a range of 9 nm or more and 36 nm or less, a ratio of the average center-to-center distance between the adjacent particles to an average primary particle diameter of the tin-doped indium oxide particles is in a range of 1.05 or more and 1.20 or less, and a roughness Ra of a film surface is in a range of 4 nm or more and 50 nm or less. 2. The infrared shielding film according to claim 1 , wherein the average primary particle diameter of the tin-doped indium oxide particles is in a range of 8 nm or more and 30 nm or less. 3. An infrared shielding material comprising the infrared shielding film according to claim 1 .
