Ultrafine particle dispersion composition, composition for interlayer for laminated glass, interlayer and laminated glass

摘要

By incorporating and dispersing infrared ray shielding ultrafine particles having an average particle size of from 10 to 60 nm and a volume ratio of ultrafine particles having particle sizes of at least 60 nm being at most 15% of all particles, in a plasticizer, it is possible to obtain an ultrafine particle dispersion composition having the ultrafine particles uniformly dispersed. By using this composition, it is possible to obtain a laminated glass or an interlayer of a laminated glass, which has a small haze value and which is excellent in the infrared ray shielding performance.
