Abstract:
A coloring photosensitive composition includes an oxime ester-based photopolymerization initiator containing a fluorine atom, a polymerizable compound having an ethylenically unsaturated double bond, an alkali-soluble resin, and a colorant, in which in a case where a film having a film thickness after drying of 2.0 µm is formed using the coloring photosensitive composition, the optical density of the film at a wavelength of 365 nm is 1.5 or more.
Abstract:
A colored radiation-sensitive composition for a color filter that includes (A) a pigment, (B) a photopolymerization initiator, and (C) a polymerizable compound, in which the colored radiation-sensitive composition satisfies the following conditions: when a colored radiation-sensitive composition layer is formed from the colored radiation-sensitive composition such that spectral transmittance at 600 nm becomes 30%, the colored radiation-sensitive composition layer includes the following characteristics: (1) spectral transmittance at 400 nm is 20% or less; (2) spectral transmittance at 550 nm is 10% or less; (3) spectral transmittance at 700 nm is 70% or more; (4) a wavelength resulting in 50% spectral transmittance is in a range of from 650 nm to 680 nm; and (5) a film thickness of the colored radiation-sensitive composition layer is in a range of from 0.55 μm to 1.8 μm.
