Title:
COMPOSITION, FILM, NEAR-INFRARED CUTOFF FILTER, LAMINATE, PATTERN FORMATION METHOD, SOLID-STATE IMAGE SENSOR, IMAGE DISPLAY DEVICE, INFRARED SENSOR AND COLOR FILTER
Document Type and Number:
WIPO Patent Application WO/2017/130825
Kind Code:
A1
Abstract:
Provided is a composition with which it is possible to form a film having an excellent infrared shielding ability and in which spectral variations do not easily occur. Further provided is a film, a near-infrared cutoff filter, a laminate, a pattern formation method, a solid-state image sensor, an image display device, an infrared sensor and a color filter. The composition includes two or more types of near-infrared-absorbing compounds, which have a maximum absorption wavelength ranging from 650 to 1,000 nm and a solubility with respect to water at 23°C of not more than 0.1 mass%. The two or more types of near-infrared-absorbing compounds include a first near-infrared-absorbing compound having a maximum absorption wavelength ranging from 650 to 1,000 nm, and a second near-infrared-absorbing compound having a maximum absorption wavelength ranging from 650 to 1,000 nm and being nearer the short wavelength side than the maximum absorption wavelength of the first near-infrared-absorbing compound. The difference between the maximum absorption wavelength of the first near-infrared-absorbing compound and the maximum absorption wavelength of the second near-infrared-absorbing compound is 1 to 150 nm.
