Description

Photosensitive resin composition, photosensitive resin layer and color filter
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority and benefit of korean patent application No. 10-2019-0051681 filed by the korean intellectual property office at 5/02/2019, which is incorporated herein by reference in its entirety.
Technical Field
The present disclosure relates to a photosensitive resin composition, a photosensitive resin layer using the photosensitive resin composition, and a color filter including the photosensitive resin layer.
Background
Among many types of displays, liquid crystal displays have advantages in brightness, thinness, low cost, low operating power consumption, and improved adhesion to integrated circuits, and have been more widely used for laptop computers, monitors, and TV screens. The liquid crystal display device includes: a lower substrate on which a black matrix, a color filter, and an ITO pixel electrode are formed; and an upper substrate on which an active circuit portion including a liquid crystal layer, a thin film transistor, and a capacitor layer and an ITO pixel electrode are formed. The color filter is formed in the pixel region by sequentially stacking a plurality of pixel portions, which are generally formed of three primary colors such as red (R), green (G), and blue (B) in a predetermined order, to form each pixel, and the black matrix layer is disposed in a predetermined pattern on the transparent substrate to form a boundary between the pixels.
The pigment dispersion method is one of methods of forming a color filter, and provides a colored thin film by repeating a series of processes such as: the method includes coating a photopolymerizable composition including a colorant on a transparent substrate including a black matrix, exposing the formed pattern, removing a non-exposed portion with a solvent, and thermally curing the same. The colored photosensitive resin composition for manufacturing a color filter according to the pigment dispersion method generally includes an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, an epoxy resin, a solvent, other additives, and the like. The pigment dispersion method is actively applied to manufacture LCDs such as mobile phones, laptop computers, monitors, and TVs. However, photosensitive resin compositions for color filters used in pigment dispersion methods have recently been required to have improved performance and excellent pattern characteristics. In particular, high color reproducibility and high brightness as well as high contrast ratio characteristics are urgently required.
The image sensor is a component for photographing in a cellular phone camera or a Digital Still Camera (DSC). Image sensors may be classified into charge-coupled device (CCD) image sensors and Complementary Metal Oxide Semiconductor (CMOS) image sensors depending on manufacturing processes and application methods. Color imaging devices for charge coupled device image sensors or complementary metal oxide semiconductor image sensors include color filters each having filter segments mixing primary colors of red, green, and blue, and the colors are separated. The most recent color filters installed in color imaging devices have a pattern size of 2 micrometers or less than 2 micrometers, which is 1/100 to 1/200 of the pattern size of conventional color filter patterns for LCDs. Therefore, increased resolution and reduced pattern residue are important factors in determining device performance.
A color filter manufactured by using the pigment-type photosensitive resin composition has limitations in brightness and contrast ratio due to the size of pigment particles. In addition, a color image forming apparatus for an image sensor requires a small dispersion particle diameter for forming a fine pattern. In order to meet the demand, efforts have been made to obtain a color filter having improved brightness and contrast ratio by introducing a dye that does not form particles instead of a pigment, thereby preparing a photosensitive resin composition suitable for the dye. However, the dye has poor durability to the pigment, such as light resistance and heat resistance, and the like, and thus the brightness may be reduced.

Detailed Description
Hereinafter, embodiments of the present invention are described in detail. However, these embodiments are exemplary, the present invention is not limited thereto and the present invention is defined by the scope of the claims.
In the present specification, when a specific definition is not otherwise provided, "substituted" means that at least one hydrogen of a compound is replaced by a substituent selected from: halogen atoms (F, Cl, Br, or I), hydroxyl groups, C1 to C20 alkoxy groups, nitro groups, cyano groups, amino groups, imino groups, azido groups, amidino groups, hydrazine groups, hydrazino groups, carbonyl groups, carbamoyl groups, thiol groups, ester groups, ether groups, carboxyl groups or salts thereof, sulfonic acid groups or salts thereof, phosphoric acid or salts thereof, C1 to C20 alkyl groups, C2 to C20 alkenyl groups, C2 to C20 alkynyl groups, C6 to C30 aryl groups, C3 to C20 cycloalkyl groups, C3 to C20 cycloalkenyl groups, C3 to C20 cycloalkynyl groups, C2 to C20 heterocycloalkyl groups, C2 to C20 heterocycloalkenyl groups, C2 to C20 heterocycloalkynyl groups, and combinations thereof.
In the present specification, "heterocycloalkyl", "heterocycloalkenyl", "heterocycloalkynyl" and "heterocycloalkylene" refer to cycloalkyl, cycloalkenyl, cycloalkynyl and cycloalkylene cyclic compounds containing at least one heteroatom of N, O, S or P, when no special definition is otherwise provided.
In the present specification, "(meth) acrylate" means both "acrylate" and "methacrylate" when a specific definition is not otherwise provided.
In the present specification, "combination" means mixing or copolymerization when a specific definition is not otherwise provided.
In the present specification, when a definition is not otherwise provided, in the chemical formula, when a chemical bond is not drawn, hydrogen is bonded at a presumably given position.
In the present specification, "+" indicates a point of bonding the same or different atoms or chemical formulae, when no special definition is otherwise provided.
The photosensitive resin composition according to the embodiment comprises: (A) a colorant comprising a core-shell structured dye; (B) a binder resin; (C) a photopolymerizable compound; (D) a photopolymerization initiator; and (E) a solvent, wherein the core is an arylcyanine-based compound and the shell is represented by chemical formula 1.
[ chemical formula 1]
Figure BDA0002473974860000091
In the chemical formula 1, the first and second,
R1is a hydrogen atom, a halogen atom, a substituted OR unsubstituted C1 to C20 alkyl group OR-OR6(wherein R is6Is a substituted or unsubstituted C1 to C20 alkyl group, and is a bonding position),
R2to R5Independently a hydrogen atom or a substituted or unsubstituted C1 to C20 alkyl group,
with the proviso that R1To R5Not simultaneously being a hydrogen atom,
m is an integer of 1 to 10,
n is an integer of 0 to 3, and
L1and L2Independently a single bond or a substituted or unsubstituted C1 to C10 alkylene.
In chemical formula 1, L1And L2May independently be a substituted or unsubstituted C1 to C10 alkylene. In this case, the solubility is improved and a structure in which a shell surrounds the arylcyanine based compound is easily formed.
For example, the core-shell dye according to the embodiment includes a non-covalent bond, i.e., a hydrogen bond, between an oxygen atom of the arylcyanine-based compound and a hydrogen atom bonded to a nitrogen atom of the shell represented by chemical formula 1.
Generally, an arylcyanine compound is generally used as a green dye because it has improved green spectral characteristics and a high molar absorption coefficient. However, after manufacturing a color resist having inferior durability compared to a pigment, brightness may be reduced during a baking process. In the photosensitive resin compositions according to the examples, a core-shell structure compound in which a shell represented by chemical formula 1 uses an arylcyanine based compound as a core to form a core-shell structure was used as a colorant instead of a conventional arylcyanine based compound. The core-shell structured compound is used as a colorant to improve the durability of the color filter, thereby realizing a color filter having high brightness and high contrast ratio.
Hereinafter, each component is specifically described.
(A) Coloring agent
The photosensitive resin composition according to the embodiment includes a core-shell structured dye.
As described above, in the color filter made of the pigment-type photosensitive resin composition, there are limitations on brightness and contrast ratio due to the pigment particle size. In addition, for application to an image sensor, a resin composition composed of smaller particles is required for forming a fine pattern. In order to achieve this, efforts have been made to implement a color filter having improved brightness and contrast ratio by introducing a dye that does not form particles instead of a pigment to prepare a photosensitive resin composition suitable for the dye. However, the dye has weak durability compared to the pigment, and thus has a limitation in improving brightness and contrast ratio.
However, in the case of the dye used as the colorant in the photosensitive resin composition according to the example, the center of the arylcyanine based compound having excellent green spectral characteristics and a high molar extinction coefficient is surrounded by the macrocyclic compound represented by chemical formula 1, the durability can be improved more than the pigment-type photosensitive resin composition and the dye-type photosensitive resin composition to implement a color filter having brightness and contrast ratio.
Specifically, the core-shell dye has a structure consisting of an arylcyanine type core around which a shell of a macrocyclic compound represented by chemical formula 1 surrounds to form a coating layer, and a shell surrounding the core. Due to this structure, that is, by having a structure in which the arylcyanine based compound exists in the ring represented by chemical formula 1, the durability of the dye having the core-shell structure may be improved and thus a color filter having high brightness and high contrast ratio may be implemented.
For example, the shell may be represented by chemical formula 2.
[ chemical formula 2]
Figure BDA0002473974860000101
In the chemical formula 2, the first and second organic solvents,
R1is a hydrogen atom, a halogen atom, a substituted OR unsubstituted C1 to C20 alkyl group OR-OR6(wherein R is6Is a substituted or unsubstituted C1 to C20 alkyl group, and is a bonding position),
R2to R5Independently a hydrogen atom or a substituted or unsubstituted C1 to C20 alkyl group,
with the proviso that R1To R5Not simultaneously being a hydrogen atom, and
n is an integer of 0 to 3.
For example, in chemical formulas 1 and 2, R1May be a hydrogen atom, and R2To R5May independently be a hydrogen atom or a substituted or unsubstituted C1 to C20 alkyl group, provided that R2To R5Is a substituted or unsubstituted C1 to C20 alkyl group.
For example, in chemical formulas 1 and 2, R1May be a halogen atom, a substituted OR unsubstituted C1 to C20 alkyl group OR-OR6(wherein R is6Is a substituted or unsubstituted C1 to C20 alkyl group, and is a bonding position), R2To R5Independently a hydrogen atom.
For example, R1May be a halogen atom, a substituted OR unsubstituted C1 to C20 alkyl group OR-OR6(wherein R is6Is a substituted or unsubstituted C1 to C20 alkyl group, and is a bonding position), and R is2To R5At least one of which may be a substituted or unsubstituted C1 to C20 alkyl group.
For example, chemical formula 2 may be represented by chemical formula 2A.

R7and R8Independently a halogen atom, a substituted OR unsubstituted C1 to C20 alkyl group OR-OR6(wherein R is6Is a substituted or unsubstituted C1 to C20 alkyl group, and is a bonding position).
For example, the shell may have a cage width of 6.5 to 7.5 angstroms and a volume of 10 to 16 angstroms. The cage width refers to an internal distance of the shell in the present disclosure, for example, a distance between two different phenylene groups in which two methylene groups are bonded in the shell represented by chemical formula 2 (see fig. 1). When the shell has a cage width within the range, a core-shell dye having a structure surrounding the arylcyanine based compound can be obtained, and thus when the core-shell dye is used as a colorant of the photosensitive resin composition, a color filter having improved durability and high luminance can be implemented.
For example, the shell may be represented by one of chemical formula 3-1 to chemical formula 3-4, but is not limited thereto.

For example, R9And R11May independently be "C1 to C20 alkyl substituted or unsubstituted by C1 to C10 alkoxy" or "C3 to C20 cycloalkyl substituted or unsubstituted by C1 to C10 alkoxy".
For example, the C1 to C10 alkoxy group may be an unsubstituted C1 to C10 alkoxy group or a C1 to C6 alkoxy group substituted with a C1 to C4 alkyl group.

For example, when the compounds represented by chemical formulas 4-1 to 4-6, and particularly the compounds represented by chemical formulas 4-6, are used for the photosensitive resin composition (e.g., as a dye), the solubility to a solvent, which will be described later, may be greater than or equal to 5, such as 5 to 10. The solubility can be obtained by the amount (g) of the dye (compound) dissolved in 100 g of the solvent. When the compound (e.g., dye) has solubility in the range, compatibility with other components (that is, a binder resin, a photopolymerizable monomer, and a photopolymerization initiator described later) in the photosensitive resin composition and coloring characteristics can be ensured, and precipitation of the dye can be prevented.
For example, the compounds represented by chemical formulas 4-1 to 4-6 may have improved heat resistance. That is, the thermal decomposition temperature measured using a thermogravimetric analyzer (TGA) may be greater than or equal to 200 deg.C, such as 200 deg.C to 300 deg.C.
The length of the compound represented by chemical formula 4 included in or composed of the core may be 1 nm to 3 nm, for example, 1.5 nm to 2 nm. When the compound represented by chemical formula 4 has a length within the range, a core-shell structure may be easily formed. In other words, the compound represented by chemical formula 4 has a length within the range and thus a structure in which the compound represented by chemical formula 4 is surrounded by a shell, which is a macrocyclic compound represented by chemical formula 1, can be easily formed. When a compound having a length outside the range is used, a structure in which the shell does not surround the core compound may not be obtained, and durability may not be improved.
For example, the core-shell structured compound may have a maximum absorption peak in wavelengths of 530 nanometers to 680 nanometers. The dye having a core-shell structure of spectral characteristics is used, for example, as a green dye and thus a photosensitive resin composition for a color filter having high brightness and high contrast ratio can be provided.
For example, the core-shell structured compound may comprise a core and a shell of the arylcyanine type at a molar ratio of 1: 1. When the core and the shell are present in the molar ratio, a coating layer (shell) surrounding the arylcyanine based core can be preferably formed.
For example, the core-shell structured dye may be represented by one of the compounds represented by chemical formulas 5-1 to 5-24, but is not limited thereto.
