Title:
COMPOSITION, CURED FILM, INFRARED TRANSMITTING FILTER, SOLID-STATE IMAGING ELEMENT, AND INFRARED SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/034082
Kind Code:
A1
Abstract:
Provided are: a composition with which it is possible to form a cured film that exhibits excellent pattern formability and solvent resistance; and a cured film, an infrared filter, a solid-state imaging element, and an infrared sensor that use said composition. The composition comprises a near-infrared transmitting black color material, a curable compound, and a solvent, wherein: the near-infrared transmitting black color material contains at least one member selected from dye compounds having a crosslinking group and pigment multimers having a dye compound-derived structure; and the ratio A/B of a minimum value A of absorbance of the composition in a wavelength range of 400-700 nm with respect to a maximum value B of absorbance of the composition in a wavelength range of 1100-1300 nm is 4.5 or higher.
