COMPOSITION, CURED FILM, NEAR-INFRARED ABSORBING FILTER, SOLID-STATE IMAGING ELEMENT, INFRARED SENSOR, AND COMPOUND

WIPO Patent Application WO/2016/031810

A1

The present invention provides a composition capable of forming a film that has an absorption range in the near-infrared region and has excellent visible transparency. Further, the present invention provides a cured film, a near-infrared absorbing filter, a solid-state imaging element, an infrared sensor, and a compound. The composition contains a near-infrared absorbing substance that has a maximum absorption wavelength in a range of 700 to 1000 nm and has a value less than or equal to 0.015 which is obtained by dividing absorbance at the wavelength of 550 nm by absorbance at the maximum absorption wavelength. A half-value width of the maximum absorption wavelength of the near-infrared absorbing substance is preferably less than or equal to 60 nm. The near-infrared absorbing substance is preferably a compound having a pyrrolo-pyrrole backbone, and more preferably, is a pyrrolo-pyrrole boron compound.
