Abstract
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.
