RED COLORING COMPOSITION FOR USE IN COLOR FILTER, COLORED FILM, COLOR FILTER, AND SOLID-STATE IMAGING DEVICE |
摘要 |
The present invention provides a red coloring composition for use in a color filter, which can form a red colored film having low incident-angle dependence and improves the color-separation properties of a solid-state imaging device including the colored film; and a colored film, a color filter, and a solid-state imaging device. The red coloring composition for use in a color filter of the present invention is a red coloring composition for use in a color filter, containing a red colorant, a near-infrared absorbent, and a polymerizable compound, in which when the coloring composition is used to form a colored film having a film thickness of 0.8 μm, the maximum value of the transmittance at a wavelength from 400 nm to 550 nm of the colored film is 7% or less, the minimum value of the transmittance at a wavelength from 600 nm to less than 700 nm of the colored film is 80% or more, and the minimum value of the transmittance at a wavelength from 700 nm to 900 nm of the colored film is 30% or less. |
