Description

Compound, photosensitive resin composition containing the same, and color filter {COMPOUND, PHOTOSENSITIVE RESIN COMPOSITION INCLUDING THE SAME AND COLOR FILTER}

This disclosure relates to compounds, photosensitive resin compositions containing the same, and color filters.

The liquid crystal display device, which is one of the display devices, has advantages such as light weight, thinness, low cost, low power consumption, and excellent adhesion to integrated circuits, and its range of use is expanding to notebook computers, monitors, TV images, etc. there is.

This 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 part consisting of a liquid crystal layer, a thin film transistor, and a storage capacitor layer and an ITO pixel electrode are formed.

Additionally, the color filter includes a black matrix layer formed in a predetermined pattern on a transparent substrate to block light at the boundary between pixels; and pixel units in which a plurality of colors (typically three primary colors of red (R), green (G), and blue (B)) are arranged in a predetermined order to form each pixel.

The pigment dispersion method, which is one of the methods of implementing a color filter, forms a colored thin film using a photosensitive resin composition containing a pigment as a colorant. Specifically, a series of processes including a process of forming a resin film by coating a photosensitive resin composition on a transparent substrate provided with a black matrix, a process of exposing a pattern on the resin film, and a process of removing the unexposed area with a solvent and heat curing it. By repeating this, a colored thin film is formed.

However, when using the pigment dispersion method, the manufacturing process of the color filter is difficult, and the quality of the manufactured color filter also has limitations. First, in order to stabilize the dispersion state of the pigment in the photosensitive resin composition and form a fine and elaborate pattern, it is necessary to use pigments with a finer particle size or to use various additives such as dispersants. In addition, storage and transportation conditions for maintaining the quality of the manufactured photosensitive resin composition at optimal levels are difficult. Moreover, the final color filter has limitations in luminance and contrast ratio resulting from the pigment particle size.

Accordingly, dyes are attracting attention as materials to replace or complement pigments. However, apart from excellent optical properties such as brightness and contrast ratio, the dyes known to date have problems with inferior heat resistance and chemical resistance compared to pigments.

One embodiment is to provide a compound that has excellent optical properties, heat resistance, chemical resistance, etc., and can replace or supplement pigments.

Another embodiment is to provide a photosensitive resin composition containing the above compound.

Another embodiment is to provide a photosensitive resin film manufactured using the photosensitive resin composition.

Another embodiment is to provide a color filter including the photosensitive resin film.

(compound)

One embodiment provides a compound represented by Formula 1:

[Formula 1]

In Formula 1,

A and B are each independently a C6 to C20 aromatic ring, or a C2 to C20 heteroaromatic ring containing 1 to 3 heteroatoms each independently selected from the group consisting of N, O and S;

Y ¹ and Y ² are each independently *-O-*, *-S-*, or *-CR ¹ R ² -*; Here, R ¹ and R ² are each independently a hydrogen atom, a halogen atom, a cyano group, or a substituted or unsubstituted C1 to C10 alkyl group;

Squarine (SQ)-based compounds generally known in the electronic materials field are 1,3-squarene-based compounds as follows.

The 1,3-squarene-based compound has a maximum absorption wavelength (λmax) of 650 nm to 850 nm, and is used as a green dye.

On the other hand, the above embodiment presents a 1,2-squarene-based compound, which is a structural isomer of the 1,3-squarene-based compound, and is an unknown compound in the electronic materials field.

The 1,2-squarene-based compound has a maximum absorption wavelength (λmax) of 500 nm to 580 nm and can function as a yellow dye, which can produce a completely different color from the 1,3-squarene-based compound.

Moreover, the molar extinction coefficient (ε) of the generally known yellow dye is about 500,000 L mol ^-1 cm ^-1 to 60,000 L mol ^-1 cm ^-1 , while the 1,2-squarene-based compound is 900,000 L mol ^-1 It has a significantly high molar extinction coefficient (ε) ranging from ¹ cm ^-1 to 100,000 L mol ^-1 cm ^-1 .

Here, “high molar extinction coefficient” means “a large amount of light absorbed by one molecule.” Accordingly, compared to the generally known yellow dye, the 1,2-squarene-based compound can exhibit a high level of color reproducibility even when the amount applied to the photosensitive resin composition is reduced, and other solids in the photosensitive resin composition (e.g. It can also contribute to increasing the amount of application of photopolymerizable compounds, etc.).

Hereinafter, the compound according to the above embodiment will be described in more detail.

A and B may each independently be a benzene ring or a naphthalene ring.

Specifically, at least one of A and B may be a naphthalene ring. In this case, compared to the case where both A and B are benzene rings, the maximum absorption wavelength (λmax) of the compound may be higher.

For example, one of A and B may be a naphthalene ring, and the other may be a benzene ring. In this way, in the case of an asymmetric structure, the molar extinction coefficient of the compound may be higher compared to the case of a symmetric structure. In the case of a symmetrical structure, the left and right D structures in the electron donating (Donor, D) - electron accepting (Acceptor, A) - electron donating (D) structure of the molecule are the same, which makes it easy to overlap between molecules. As a result, Interference of electronic levels occurs due to interactions between molecules, which tends to reduce the intensity of the absorption graph and widen the half width. On the other hand, the asymmetric structure is in the form of D-A-D’, which makes it relatively difficult to overlap between molecules, reducing interactions between molecules. Additionally, if a substituent is introduced outside the aromatic ring of the donor with an asymmetric structure, the above advantages can become more advantageous. The effect of a high molar extinction coefficient is as described above.

Y ¹ and Y ² may each independently be *-O-*, *-S-*, or *-C(CH ₃ ) ₂ -*.

Specifically, Y ¹ and Y ² may be different from each other. In the case of such an asymmetric structure, the molar extinction coefficient of the compound may be higher compared to the case of a symmetric structure. The effect of a high molar extinction coefficient is as described above.

R ¹ and R ² are each independently a hydrogen atom, a halogen atom, a cyano group, or a substituted or unsubstituted C1 to C20 alkyl group; The substituent for the C1 to C20 alkyl group may be a sulfurous acid (*-SO ₃ ) group, a (meth)acrylate group, or an epoxy group.

Specifically, here, the C1 to C20 alkyl group may be terminally substituted with a sulfurous acid (*-SO ₃ ) group, a (meth)acrylate group, or an epoxy group. When the parent core structure of the compound is the same, the properties of the compound may vary depending on the type of terminal substituent. For example, if the terminal substituent is a sulfurous acid (*-SO ₃ ) group, the ( ) effect can be strengthened, if the terminal substituent is a (meth)acrylate group, heat resistance can be strengthened, and if the terminal substituent is an epoxy group, chemical resistance can be strengthened.

Meanwhile, R ¹ and R ² may be different from each other. In the case of such an asymmetric structure, the molar extinction coefficient of the compound may be higher compared to the case of a symmetric structure. The effect of a high molar extinction coefficient is as described above.

R ³ and R ⁴ are each independently a substituted or unsubstituted C1 to C20 alkyl group; The substituent for the C1 to C20 alkyl group may be a sulfurous acid (*-SO ₃ ) group, a (meth)acrylate group, or an epoxy group.

Here, the C1 to C20 alkyl group may be terminally substituted with a sulfurous acid (*-SO ₃ ) group, a (meth)acrylate group, or an epoxy group. The effects of the terminal substituents are as described above.

Meanwhile, R ³ and R ⁴ may be the same.

As previously mentioned, the maximum absorption wavelength (λmax) of the compound may be 500 nm to 580 nm.

Specifically, when both A and B are benzene rings, the maximum absorption wavelength (λmax) of the compound may be 500 nm to 550 nm. On the other hand, when at least one of A and B is a naphthalene ring, the maximum absorption wavelength (λmax) of the compound may be increased to 550 nm to 580 nm.

As described previously, the compound exhibits a maximum absorption wavelength (λmax) in the range of 500 nm to 580 nm. Among them, the steeper the slope of the absorbance graph (i.e., absorbance/wavelength) in the wavelength range of 520 nm to 550 nm, the molar extinction coefficient. is high.

Accordingly, the above compound has a significantly higher molar extinction coefficient compared to generally known yellow dyes.

More specifically, the molar extinction coefficient (ε) of the compound may be 90,000 L mol ^-1 cm ^-1 to 120,000 L mol ^-1 cm ^-1 .

Here, when the compound has a symmetric structure, the molar extinction coefficient (ε) of the compound may be 90,000 L mol ^-1 cm ^-1 to 100,000 L mol ^-1 cm ^-1 . On the other hand, when the compound has an asymmetric structure, the molar extinction coefficient (ε) of the compound can be as high as 100,000 L mol ^-1 cm ^-1 to 120,000 L mol ^-1 cm ^-1 .

Moreover, since the compound has a significantly high molar extinction coefficient (ε) of 90,000 L mol ^-1 cm ^-1 to 100,000 L mol ^-1 cm ^-1 , a high level of color reproducibility is achieved even when the amount applied to the photosensitive resin composition is reduced. It can also contribute to increasing the application amount of other solids (for example, photopolymerizable compounds, etc.) in the photosensitive resin composition.
