Title:
COLOR FILTER RED COLORING COMPOSITION, COLORED FILM, COLOR FILTER, AND SOLID-STATE IMAGE SENSOR
Document Type and Number:
Japanese Patent JP2015163955
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a color filter red coloring composition capable of forming a red colored film with suppressed incident angle dependence and enhancing color separability of solid-state image sensors having such colored films, and to provide the colored film, a color filter, and a solid-state image sensor.SOLUTION: A color filter red coloring composition contains a red colorant, a near-infrared absorbent, and a polymerizable compound. When a colored film having a thickness of 0.8 μm is formed using the coloring composition, a maximum transmittance of the colored film shall be no greater than 7% in a wavelength range between 400 nm and 550 nm, inclusive, while a minimum transmittance thereof shall be no less than 80% in a wavelength range between 600 nm, inclusive, and 700 nm, non-inclusive, and no greater than 30% in a wavelength range between 700 nm and 900 nm, inclusive.
