Title:
NEAR-INFRARED ABSORBING ORGANIC PIGMENT, PIGMENT DISPERSION, CURABLE COMPOSITION, FILM, NEAR-INFRARED CUT FILTER, LAMINATE, SOLID STATE IMAGING ELEMENT, IMAGE DISPLAY DEVICE, AND INFRARED SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/056127
Kind Code:
A1
Abstract:
Provided is a near-infrared ray absorbing organic pigment having exceptional transparency in the visible ray region and exceptional heat resistance. In addition, provided are a pigment dispersion, a curable composition, a film, a near-infrared cut filter, a laminate, a solid state imaging element, an image display device, and an infrared sensor. In a powder X-ray diffraction spectrum, this near-infrared ray absorbing organic pigment has a peak of diffraction intensity in a region in which the diffraction angle 2θ is 5 to 12°, and the full width at half maximum of a peak at which the diffraction intensity in said region is highest is 0.3 to 0.6°.
