組成物、膜、赤外線透過フィルタ、固体撮像素子および光センサ
Document Type and Number:
Japanese Patent JP6931717
Kind Code:
B2
Abstract:
Provided are: a composition capable of producing a film which has a uniform thickness and has a suppressed occurrence of foreign matter defects under a high temperature and high humidity environment; an infrared transmission filter; a solid state imaging device; and an optical sensor. This composition contains: a specific metal azo pigment; a coloring material having a maximum absorption in the wavelength range of 400-700 nm; and a compound having an ethylenically unsaturated bonding group and/or a compound having a cyclic ether group. In this composition, A/B, which is the ratio of a minimum absorbance value A in the wavelength range of 400-600 nm to a maximum absorbance value B in the wavelength range of 1000-1300 nm, is at least 4.5. Said metal azo pigment contains: at least one anion species selected from among an azo compound represented by formula (I) and a tautomeric azo compound thereof; two or more kinds of metal ions; and a melamine compound.
