Photosensitive coloring composition for infrared transmission filter for solid-state image sensor, color filter for solid-state image sensor, and solid-state image sensor

摘要

PROBLEM TO BE SOLVED: To provide a colored composition for a solid-state image sensor, which gives a color filter excellent in light-shieling property in a visible light region and transmissivity in an infrared region, an infrared transmission filter using the colored composition, and a solid-state image sensor using the infrared transmission filter.SOLUTION: A photosensitive colored composition for an infrared transmission filter to be applied to a solid-state image sensor is provided, which has such characteristics that when a filter having a film thickness of 1.0 μm is formed, a maximum of the light transmittance of the filter in a wavelength range from 400 to 620 nm is 5% or less, a maximum of the light transmittance in a wavelength range from 620 to 730 nm is 13% or less, and a minimum of the light transmittance in a wavelength range from 800 to 1000 nm is 90% or more, and that the infrared transmission filter is used in combination with at least two filters selected from the group consisting of a red filter, green filter, blue filter, cyan filter, magenta filter and yellow filter.SELECTED DRAWING: None
