Title:
NEAR-INFRARED-SHIELDING ULTRAFINE PARTICLE DISPERSION BODY, NEAR-INFRARED-SHIELDING INTERMEDIATE FILM, NEAR-INFRARED-SHIELDING LAMINATED STRUCTURE, AND PRODUCTION METHOD FOR NEAR-INFRARED-SHIELDING ULTRAFINE PARTICLE DISPERSION BODY
Document Type and Number:
WIPO Patent Application WO/2018/216595
Kind Code:
A1
Abstract:
Provided is a near-infrared-shielding ultrafine particle dispersion body or the like that has an excellent near-infrared-shielding function, a low haze value, excellent design properties, and inhibited color tone change and blue haze phenomenon in outdoor use, and that is obtained by using near-infrared-shielding ultrafine particles which are transparent in a visible light region, have excellent near-infrared-shielding characteristics, and are produced with high productivity. Provided is a near-infrared-shielding ultrafine particle dispersion body or the like which is a dispersion of ultrafine particles having near-infrared-shielding characteristics in a solid medium, wherein the ultrafine particles are composite tungsten oxide ultrafine particles (A) represented by general formula MxWyOz, the ratio value of the top intensity of the XRD peak of the composite tungsten oxide ultrafine particles (A) with respect to the XRD peak intensity, defined as 1, of the (220) plane of a silicon powder standard sample is 0.13 or more, the solid medium contains a resin binder (B) and a weather resistance improver (C), and the weather resistance improver (C) contains at least one selected from benzotriazole-based UV absorbents, triazine-based UV absorbents, and benzophenone-based UV absorbents.
