Document Type and Number:
Japanese Patent JP6833728
Kind Code:
B2
Abstract:
Provided is a composition with which a film having excellent infrared shielding properties and reduced spectral variation can be formed. In addition, provided are a film, a near infrared cut filter, a laminate, a pattern forming method, a solid image pickup element, an image display device, an infrared sensor, and a color filter. The composition includes two or more near infrared absorbing compounds having an absorption maximum in a wavelength range of 650 to 1000 nm and having a solubility of 0.1 mass% or lower in water at 23°C, in which the two or more near infrared absorbing compounds include a first near infrared absorbing compound having an absorption maximum in a wavelength range of 650 to 1000 nm, and a second near infrared absorbing compound having an absorption maximum in a wavelength range of 650 to 1000 nm which is shorter than the absorption maximum of the first near infrared absorbing compound, and a difference between the absorption maximum of the first near infrared absorbing compound and the absorption maximum of the second near infrared absorbing compound is 1 to 150 nm.
