Near-infrared shielding ultrafine dispersion, near-infrared shielding interlayer, near-infrared shielding junction structure, and method of manufacturing near-infrared shielding ultrafine dispersion

摘要

By using near-infrared shielding ultrafine particles, which are transparent in the visible region, have excellent near-infrared shielding properties, and are manufactured with high productivity, have a good near-infrared shielding function, have a low haze value, excellent design, and furthermore, when used outdoors. The near-infrared shielding ultrafine dispersion | distribution etc. which the change of the hue in and blue haze phenomenon suppressed are provided. A near infrared shielding ultrafine particle dispersion in which ultrafine particles having near infrared shielding properties are dispersed in a solid medium, wherein the ultrafine particles are composite tungsten oxide ultrafine particles (A) represented by the general formula MxWyOz, and the XRD peak intensity of the (220) plane of a silicon powder standard sample The value of the ratio of the XRD peak of the composite tungsten oxide ultrafine particle (A) to the top strength when the value of 1 is 1 is 0.13 or more, and the solid medium contains a resin binder (B) and a weather resistance improver (C). The said weatherability improving agent (C) provides the near-infrared shielding ultrafine particle dispersion etc. containing 1 or more types chosen from a benzotriazole type ultraviolet absorber, a triazine type ultraviolet absorber, and a benzophenone type ultraviolet absorber.
