NEAR INFRARED SHIELDING ULTRAFINE PARTICLE DISPERSION, INTERLAYER FOR SOLAR SHADING, INFRARED SHIELDING LAMINATED STRUCTURE, AND METHOD FOR PRODUCING NEAR INFRARED SHIELDING ULTRAFINE PARTICLE DISPERSION.

摘要

The present invention provides a near infrared shielding ultrafine particle dispersion that exhibits transparency in a visible light region, has excellent near infrared shielding properties, suppresses the blue haze phenomenon, and can be produced with high productivity. Provided is a near infrared shielding ultrafine particle dispersion obtained by dispersing ultrafine particles having near infrared shielding properties in a solid medium, said dispersion being characterized in that the ultrafine particles are composite tungsten oxide ultrafine particles, and when the value for the XRD peak intensity of a (220) plane of a silicon powder standard sample (produced by NIST, 640c) is defined as 1, the value for the XRD peak top intensity ratio of the composite tungsten oxide ultrafine particles is 0.13 or more.
