Abstract
Description
[Technical field]
[0001] The present invention relates to a photosensitive composition used for forming a color filter for use in a solid-state imaging device, an image display device, or the like. [Background technology]
[0002] In recent years, the demand for color filters used in liquid crystal displays, organic electroluminescence displays, digital cameras, smartphones, infrared sensors, etc. has been growing due to their widespread use. Color filters separate the light that passes through them, and these colors are then synthesized to form an image. For this reason, color filters are required to have high brightness, high contrast, and color reproducibility.
[0003] As colorants excellent in luminance, contrast and color reproducibility, the use of phthalocyanine compounds described in Patent Documents 1 to 4 has been investigated. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2019-113732 A [Patent Document 2] Patent Publication No. 2021-056382 [Patent Document 3] International Publication No. 2023 / 002875 Summary of the Invention [Problem to be solved by the invention]
[0005] As a result of thorough investigation of the phthalocyanine compounds described in Patent Documents 1 to 3, it was found that the brightness of color filters using these phthalocyanine compounds decreases when irradiated with light in a low-oxygen environment. It was also found that there are problems with pattern formability and electrical properties.
[0006] An object of the present invention is to provide a photosensitive composition capable of forming a color filter having excellent pattern formability, electrical properties, and light resistance in a low-oxygen environment. [Means for solving the problem]

[0008] According to the present invention, there can be provided a photosensitive composition capable of forming a color filter having excellent pattern formability, electrical properties, and light resistance in a low-oxygen environment. The present invention also can provide a film, a color filter, a solid-state imaging device, and an image display device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, the embodiment for carrying out the photosensitive composition of the present invention will be described in detail. Note that the present invention is not limited to the following embodiment, and can be modified within the scope of the problem that can be solved.
[0010] In this specification, unless otherwise specified, "(meth)acryloyl", "(meth)acrylic", "(meth)acrylic acid", "(meth)acrylate", or "(meth)acrylamide" respectively mean "acryloyl and / or methacryloyl", "acrylic and / or methacrylic", "acrylic acid and / or methacrylic acid", "acrylate and / or methacrylate", or "acrylamide and / or methacrylamide". In addition, "CI" means Color Index (CI; published by The Society of Dyers and Colourists). In this specification, a polymerizable unsaturated group is an ethylenically unsaturated double bond. As used herein, a monomer is a compound that will polymerize to form a resin. A monomer is in an unreacted state, and a monomer unit is a monomer that has been polymerized to form a polymer. In this specification, for low molecular weight compounds whose molecular weight can be specified, the molecular weight is a calculated value or measured by ESI-MS (electrospray ionization mass spectrometry), and for compounds having a molecular weight distribution, the molecular weight is a polystyrene-equivalent weight average molecular weight measured by gel permeation chromatography using tetrahydrofuran as a solvent. In this specification, a numerical range expressed using "to" means a range that includes the numerical values before and after "to" as the lower limit and upper limit.
[0011] <Photosensitive composition> A photosensitive composition according to one embodiment of the present invention is a photosensitive composition comprising a colorant (A), an alkali-soluble resin (B), a polymerizable compound (C), and a polymerization initiator (D), the color material (A) contains a green color material (A1) and a yellow color material (A2); The green colorant (A1) contains a green colorant (a1) represented by the following general formula (1): The yellow colorant (A2) is characterized in that it contains a yellow colorant (a2) containing two or more metal azo compounds having at least different metal species selected from the group consisting of metal azo compounds represented by the following general formula (2) and metal azo compounds having a tautomeric structure thereof, and a compound represented by the following general formula (3): General formula (1) [ka] (In general formula (1), X1~X 16 each independently represents a hydrogen atom, a halogen atom, or -Y1-R1, where Y1 represents a divalent linking group and R1 represents a monovalent organic group. 16 At least one of them represents a halogen atom, and at least one of them represents -Y1-R1. M represents a metal atom, a metal oxide, or a metal halide. General formula (2) [ka] (In general formula (2), R1 and R2 each independently represent -OH, -NH2, or -NHR5, R3 and R4 each independently represent =O or =NR5, and R5 each independently represent a hydrogen atom or an alkyl group which may have a substituent. Me is a metal atom selected from the group consisting of Ni, Zn, Cu, Al, Fe, Co, and Mn. General formula (3) [ka] (In the general formula (3), each R6 independently represents a hydrogen atom or an alkyl group which may have a substituent.)
[0012] The mechanism by which the photosensitive composition having the above-mentioned configuration can solve the problems of the present invention is not clear, but is speculated as follows.
[0013] It is presumed that the green colorant (a1) represented by general formula (1) (hereinafter, simply referred to as the green colorant (a1)) becomes excited when irradiated with light in a low-oxygen environment, and easily receives electrons from the surrounding electron-supplying components, resulting in a decrease in brightness. However, a yellow colorant (a2) (hereinafter, simply referred to as the yellow colorant (a2)) containing two or more metal azo compounds with at least different metal species selected from the group consisting of metal azo compounds represented by general formula (2) and metal azo compounds having tautomeric structures thereof, and a compound represented by general formula (3), is less likely to transfer electrons compared to other yellow colorants. Therefore, it is presumed that the supply of electrons to the green colorant (a1) is small, and the brightness is less likely to decrease. It is also presumed that the electrical properties are excellent due to the small amount of electron transfer. Furthermore, it is presumed that the yellow colorant (a2) is more transparent to light of about 365 nm, which is the dominant wavelength of ultra-high pressure mercury lamps used in the production of color filters, than other yellow colorants, and thus has excellent pattern formability because it can suppress the difference in photocurability between the upper and lower parts of the pattern.

[0090] [Alkali-soluble resin (B)] The photosensitive composition of the present invention contains an alkali-soluble resin (B).
[0091] The alkali-soluble resin (B) is not particularly limited as long as it dissolves in the alkali developer described below, and any known resin can be used. Examples of the resin include (meth)acrylic resin, styrene resin, styrene / (meth)acrylic resin, epoxy resin, urethane resin, polycarbonate resin, polyester resin, polyether resin, polyimide resin, polyamideimide resin, cyclic olefin resin, polysiloxane resin, etc.
[0092] Examples of the structure of the alkali-soluble resin (B) include a random structure, a block structure, a graft structure, a comb structure, a star structure, etc. Among these, a lactam structure is preferred from the viewpoint of developability.
[0093] The weight average molecular weight (Mw) of the alkali-soluble resin (B) is preferably from 3,000 to 50,000, and more preferably from 4,000 to 40,000.

[0097] (Alkali-soluble resin (B1) having a monomer unit (b1) having a homopolymer glass transition temperature of 0° C. or lower) From the viewpoint of pattern formability, the photosensitive composition of the present invention preferably contains, as the alkali-soluble resin (B), an alkali-soluble resin (B1) having a monomer unit (b1) whose homopolymer has a glass transition temperature of 0° C. or lower (hereinafter, also simply referred to as the alkali-soluble resin (B1)).
[0098] The alkali-soluble resin (B1) moderately softens when exposed to heat. Therefore, it is assumed that heat sagging occurs easily during the post-bake process, resulting in a good cross-sectional shape of the pattern. In addition, because it has flexibility, rigid parts formed by polymerization of the polymerizable compound (C) described below and flexible parts of the alkali-soluble resin (B1) exist in the film, which can effectively relieve external or internal stress. Therefore, it is assumed that the difference in cure shrinkage between the surface and the inside of the pattern is reduced, and the occurrence of wrinkles on the surface can be suppressed.
[0099] The alkali-soluble resin (B1) is not particularly limited, and known resins can be used. For example, a monomer forming a monomer unit (b1) having a homopolymer glass transition temperature of 0° C. or lower, and a copolymer with any other copolymerizable monomer can be used.
[0100] The glass transition temperature (hereinafter, also referred to as Tg) may be a measured Tg obtained by actual measurement. Specifically, the measured Tg may be a value measured by differential scanning calorimetry (DSC). However, if measurement is difficult due to decomposition of the resin, etc., the calculated Tg obtained by the following formula is applied. 1 / Tg=W1 / Tg1+W2 / Tg2+······+W n / Tg n Here, the resins to be calculated are W1 to W n n types of monomer components up to W n is the weight fraction of the nth monomer, Tg n is the glass transition temperature (absolute temperature) of the homopolymer of the nth monomer.

Immergut, EH.
