摘要

Provided is a near-infrared absorbing organic pigment having excellent near-infrared shielding property. In addition, a resin composition, a method for producing a near-infrared absorbing organic pigment, a method for spectroscopically adjusting a near-infrared absorbing organic pigment, a film, a laminate, a near-infrared cut filter, a near-infrared transmitting filter, a solid-state image sensor, an image display device and an infrared sensor. I will provide a. The near-infrared absorbing organic pigment has a maximum absorption wavelength in the wavelength range of 650 to 1400 nm, and A550 / Amax, which is the ratio of the absorbance A550 at the wavelength of 550 nm to the absorbance Amax at the maximum absorption wavelength, is less than 0.1, and is average. The primary particle size is 1 to 200 nm, and the value of the degree of crystallization measured by the powder X-ray diffraction spectrum is 0.70 to 0.98.
