Document Type and Number:
WIPO Patent Application WO/2016/035633
Kind Code:
A1
Abstract:
Provided are: an infrared-light shielding composition having excellent drying resistance and excellent flat application properties, whereby an infrared-light cutoff filter can be formed in which the occurrence of a pattern on the surface thereof is suppressed; an infrared-light cutoff filter; and a solid-state imaging element. This infrared-light shielding composition includes at least metal-containing tungsten oxide particles, a resin binder, a solvent A having a boiling point of 170°C to 200°C at 1 atmosphere, and a solvent B different from the solvent A, the content of the solvent A being 0.1-20% by mass with respect to the total mass of the infrared-light shielding composition.
