NEAR INFRARED RAY ABSORPTION MATERIAL MICRO-PARTICLE DISPERSION, NEAR INFRARED RAY ABSORBER, NEAR INFRARED RAY ABSORPTION LAMINATE, COMBINED STRUCTURE FOR NEAR INFRARED RAY ABSORPTION

摘要

Provided are a near infrared ray absorption material micro-particle dispersion, a near infrared ray absorption laminate, and a combined structure for near infrared ray absorption, that can exhibit higher near infrared absorption properties than conventional near infrared ray absorption material micro-particle dispersions, near infrared ray absorption laminates, or combined structures for near infrared ray absorption that include tungsten oxide or a composite tungsten oxide. Provided are a near infrared ray absorption material micro-particle dispersion and a near infrared ray absorption laminate and a combined structure for near infrared ray absorption that use said dispersion, said dispersion including in a polypropylene resin: composite tungsten oxide micro-particles including a hexagonal crystal structure; and a polymer compound having maleic anhydride introduced therein.
