Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A coloring photosensitive composition comprising: 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, wherein the colorant includes C. I. Pigment Green 58, and 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. 2. The coloring photosensitive composition according to claim 1 , further comprising: an oxime-based photopolymerization initiator other than the oxime ester-based photopolymerization initiator containing a fluorine atom. 3. The coloring photosensitive composition according to claim 1 , wherein the colorant further includes at least one selected from the group consisting of C. I. Pigment Yellow 138, C. I. Pigment Yellow 150, and C. I. Pigment Yellow 185. 4. The coloring photosensitive composition according to claim 1 , wherein the colorant further includes at least one selected from the group consisting of C. I. Pigment Yellow 150 and C. I. Pigment Yellow 185. 5. The coloring photosensitive composition according to claim 1 , further comprising: an α-aminoketone-based photopolymerization initiator, wherein the mass ratio of the oxime ester-based photopolymerization initiator containing a fluorine atom to the α-aminoketone-based photopolymerization initiator is 1:1.5 to 1:10.
