Title:
COMPOSITION, FILM, LAMINATE, INFRARED TRANSMISSION FILTER, SOLID-STATE IMAGING DEVICE AND INFRARED SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/054281
Kind Code:
A1
Abstract:
Provided is a composition capable of forming a film through which infrared light can pass while noise derived from visible light is little. Also provided are a film, a laminate, an infrared transmission filter, a solid-state imaging device, and an infrared sensor. The composition includes: a color material which transmits infrared light and shields visible light; an infrared light absorbent; and a curable compound. The infrared light absorbent includes a material which shields light in a wavelength range of 1000-1200 nm (exclusive of 1000). In this composition, A/B, which is the ratio of the minimum value A of absorbance in a wavelength range of 400-1100 nm to the maximum value B of absorbance in a wavelength range of 1400-1500 nm, is 4.5 or more.
