Japanese Patent JP6976341
Kind Code:
B2
Abstract:
Provided is a near infrared ray-absorbable organic pigment having excellent near infrared ray-shielding performance. Also provided are: a resin composition; a method for producing a near infrared ray-absorbable organic pigment; a method for adjusting a spectrum of a near infrared ray-absorbable organic pigment; a film; a laminate; a near infrared ray cut filter; a near infrared ray transmission filter; a solid-state imaging element; an image display device; and an infrared ray sensor. The near infrared ray-absorbable organic pigment has: a maximum absorption wavelength falling within the wavelength range from 650 to 1400 nm; an A550/Amax value, which is a ratio of an absorbance A550 at a wavelength of 550 nm to an absorbance Amax at a maximum absorption wavelength, of less than 0.1; an average primary particle diameter of 1 to 200 nm; and a degree of crystallinity of 0.70 to 0.98 as measured from a powder X-ray diffraction spectrum.
