ABSORBER MICROPARTICLE DISPERSION WITH EXCELLENT LONG-TERM STABILITY, OBJECT CONTAINING DISPERSED ABSORBER MICROPARTICLES, AND PRODUCTION METHODS THEREFOR

摘要

Provided are: an object containing dispersed particles which has excellent heat-ray-shielding properties and exhibits long-term high-temperature stability; and a dispersion for producing the object. The dispersion is a dispersion of absorber microparticles which comprises a liquid medium, the absorber microparticles dispersed in the medium, and a phosphorous ester compound, wherein the absorber microparticles are one or more kinds of oxide microparticles selected from among microparticles of tungsten oxides represented by the general formula WyOz and microparticles of composite tungsten oxides represented by the general formula MxWyOz and the phosphorous ester compound is represented by a given structural formula and is contained in an amount exceeding 500 parts by mass but not larger than 50,000 parts by mass per 100 parts by mass of the absorber microparticles.
