The present invention relates to a xanthene compound and a photosensitive resin composition containing the same. In addition, the present invention relates to a photosensitive material and a color filter produced using the photosensitive resin composition, and a display device containing the same.

Background Art

In recent years, color filters are required to have high brightness and high contrast. In addition, one of the main goals of display device development is to achieve differentiation of display element performance and improve the productivity of the manufacturing process by improving color purity.

Since the pigment type used as the colorant of the color filter in the past exists in the color photoresist in a particle dispersion state, there are difficulties in adjusting the brightness and contrast by adjusting the pigment particle size and distribution. In the case of pigment particles, the dissolution and dispersibility are reduced by condensation in the color filter, and multiple scattering of light occurs due to the large particles of condensation (aggregation). The scattering of this polarized light is considered to be the main reason for reducing the contrast. Although people continue to make efforts to improve brightness and contrast by ultra-micronization and dispersion stabilization of pigment, the freedom is limited in the colorant selection for realizing the color coordinates of high color purity display devices. In addition, the pigment dispersion method using the colorant, especially the pigment, which has been developed, has reached the limit in improving the color purity, brightness and contrast of the color filter using it.

Therefore, there is a demand for the development of new colorants that can improve color reproduction, brightness, and contrast by improving color purity.

DETAILED DESCRIPTION

Next, this specification is described in more detail.

In this specification, when it is stated that a certain component is located “on” another component, it not only includes a case where the certain component is in contact with the other component, but also includes a case where other components are present between the two components.

In the present specification, when it is stated that a certain part “includes” a certain constituent element, unless there is a particular description to the contrary, it means that other constituent elements may be further included, rather than excluding other constituent elements.

According to one embodiment of the present specification, a compound represented by the above Chemical Formula 1 is provided.

The present invention has excellent solubility in organic solvents by including a compound represented by the above chemical formula 1. Specifically, the above chemical formula 1 can increase the solubility in organic solvents by replacing the aryl group substituted on the nitrogen of the xanthene structure with a substituent containing sulfur (S) and including a bulky substituent such as a dianhydride group containing a nitrogen atom.

In addition, when the aromatic group substituted on the nitrogen of the xanthene structure in the above Chemical Formula 1 is substituted with a substituent containing sulfur (S), the fluorescence intensity is reduced compared to the case where it is substituted with a substituent not containing sulfur (S), and excellent contrast can be obtained without adding an additional pigment.

This leads to an increase in solubility, thereby preventing aggregation of pigments and reducing the amount of material required for pigment dispersion, thereby improving economic efficiency.

In addition, the contrast ratio (CR) can be improved, and excellent heat resistance can be achieved. In order to reduce the luminescence (fluorescence or phosphorescence) of the molecule, there are methods of reducing the planarity within the molecule or introducing molecules that absorb light. When introducing molecules that absorb light, it is difficult to selectively absorb only the light of the luminescent wavelength because all the light of the molecules that need to emit light and the external light are absorbed. Therefore, in order to reduce the planarity within the molecule, a bulky group with large steric hindrance is introduced.

When a molecule in an excited state absorbs light in its ground state and transfers energy through a vibration mode or a rotation mode, non-radiative decay can occur, that is, light emission can be reduced.

The greater the planarity, the more difficult the non-radiative attenuation is, thereby increasing the intensity of the luminescence. By introducing a large substituent and reducing the planar area, the intensity of the luminescence can be reduced by non-radiative attenuation. For non-radiative attenuation, long alkyl groups, branched alkyl groups, alkoxy groups, and amine groups can be introduced. However, in the case of alkyl groups, there is a disadvantage of insufficient heat resistance.

Furthermore, in the case of an alkoxy group and an amine group, they function as electron donating groups, thereby being able to change the absorption wavelength of the molecule that absorbs light.

In contrast, when molecules containing sulfur (S) are introduced, the effect of electron donating groups in the molecules that absorb light is reduced, and heat resistance can be maintained.

When sulfur atoms, which are larger in size than carbon, nitrogen, and oxygen, are introduced, the energy of the excited molecules moves to sulfur atoms having various energy levels, and moves between the various energy levels of sulfur atoms, that is, according to vibration modes and rotation modes, and non-radiative decay can occur at the same time. Due to such characteristics, when sulfur atoms are introduced, the intensity of luminescence in the molecule can be reduced.

When molecules that emit light are used in liquid crystal displays (LCDs), the contrast ratio (CR) decreases, which may cause quality degradation. Therefore, various methods have been adopted to try to reduce the light emission.

Currently, molecules that absorb light are added to suppress the decrease in contrast ratio (CR), but this results in a decrease in color purity and an increase in the amount of colorant used.

The color filter may be manufactured using a photosensitive resin composition including the compound represented by Chemical Formula 1. The photosensitive resin composition is applied on a substrate to form a coating film, and the coating film is exposed, developed, and cured, thereby forming the color filter.

The photosensitive resin composition according to one embodiment of the present specification has excellent heat resistance and little color change due to heat treatment, so that a color filter having high color reproduction rate, high brightness and high contrast can be provided even after a curing process during color filter production.

The substrate may be a glass plate, a silicon wafer, or a plate made of a plastic base material such as polyethersulfone (PES) or polycarbonate (PC), and the type thereof is not particularly limited.

Specifically, the photosensitive resin composition according to one embodiment of the present specification can be spin coated on glass (5×5 cm ² ), and pre-baked at 100° C. for 100 seconds to form a film. The gap between the substrate on which the film is formed and the photomask is set to 250 μm, and the entire surface of the substrate is irradiated with an exposure amount of 40 mJ/cm ² using an exposure machine. Then, the exposed substrate is developed in a developer (potassium hydroxide (KOH), 0.05%) for 60 seconds, and a post-baking treatment can be performed at 230° C. for 20 minutes to produce a substrate.

The heat resistance evaluation can be measured according to the method described below, and the substrate prepared according to the above embodiment is used to obtain a transmittance spectrum in the visible light region of 380nm to 780nm using a spectrometer. In addition, the pre-baked substrate is further post-baked at 230°C for 20 minutes, and the transmittance spectrum is obtained in the same equipment and measurement range.

The spectrometer may be a spectrometer manufactured by MCPD-Otsuka Corporation, but is not limited thereto.

The color change (hereinafter referred to as ΔEab) is calculated using the transmittance spectrum obtained above and the C light source backlight, and the obtained value E (L*, a*, b*). A small ΔEab value indicates that the color has excellent heat resistance. When the value has ΔEab<3, it can be used as a color filter pigment, and it can be said to be a colorant with excellent heat resistance. Specifically, the formula for calculating ΔEab is as follows.

[Calculation formula 1]

ΔEab(L*, a*, b*)={(ΔL*) ² +(Δa*) ² +(Δb*) ² } ^1/2

The substrate produced by the substrate production method is placed between two polarizing plates using a contrast meter, and the brightness when the two polarizing plates are horizontal and when the two polarizing plates are orthogonal is measured, and the contrast ratio is calculated by the following calculation formula 2.

[Calculation formula 2]

Contrast = Brightness when two polarizing films are horizontal / Brightness when two polarizing films are vertical

The above-mentioned contrast measurement instrument may be CT-1, a measurement instrument produced by ZOENTECH, but is not limited thereto.

The color filter may include a red pattern, a green pattern, a blue pattern, and a black matrix.

According to another embodiment, the color filter may further include an overcoat layer.

For the purpose of improving contrast, a lattice-shaped black pattern called a black matrix can be arranged between the color pixels of the color filter. As the material of the black matrix, chromium can be used. In this case, chromium can be evaporated on the entire glass substrate and the pattern can be formed by etching. However, considering the high cost of the process, the high reflectivity of chromium, and the environmental pollution caused by chromium waste liquid, a resin black matrix obtained by a pigment dispersion method that can be micro-processed can be used.

The black matrix may use black pigment or black dye as colorant. For example, carbon black may be used alone, or carbon black and a coloring pigment may be mixed and used. At this time, due to the insufficient coloring pigment of the mixed light-shielding property, even if the amount of the colorant is relatively increased, the strength of the film or the adhesion to the substrate may not be reduced.

A display device including the color filter according to the present specification is provided.

The above-mentioned display device can be any one of a plasma display panel (PDP), a light emitting diode (LED), an organic light emitting diode (OLED), a liquid crystal display (LCD), a thin film transistor-liquid crystal display (LCD-TFT), and a cathode ray tube (CRT).

<Experimental example>

Substrate production

The photosensitive resin compositions of Examples 1 to 18 and Comparative Examples 1 to 4 were used to prepare substrates. Specifically, the photosensitive resin compositions of Examples 1 to 18 and Comparative Examples 1 to 4 were spin coated on glass (5×5 cm ² ) and pre-baked at 100° C. for 100 seconds to form films.

The gap between the substrate on which the film is to be formed and the photomask is set to 250 μm, and the entire surface of the substrate is irradiated with an exposure dose of 40 mJ/cm ² using an exposure machine. Then, the exposed substrate is developed in a developer (potassium hydroxide (KOH), 0.05%) for 60 seconds, and a post-baking treatment is performed at 230° C. for 20 minutes to prepare the substrate.

Heat resistance evaluation

The substrate prepared according to the above-mentioned substrate preparation method was used to obtain a transmittance spectrum in the visible light region ranging from 380nm to 780nm using a spectrometer (MCPD-Otsuka Co., Ltd.). In addition, the pre-baked substrate was further post-baked at 230°C for 20 minutes, and the transmittance spectrum was obtained using the same equipment and measurement range.

The color change (hereinafter referred to as ΔEab) was calculated using the obtained transmittance spectrum and C light source backlight and the obtained values E (L*, a*, b*), and is shown in Table 1 below.

A small ΔEab value indicates excellent heat resistance of the color.

When the value of ΔEab<3 is achieved, the colorant can be used as a color filter dye, and can be said to be a colorant with excellent heat resistance. Specifically, the formula for calculating ΔEab is as follows.

[Calculation formula 1]

ΔEab(L*, a*, b*)={(ΔL*) ² +(Δa*) ² +(Δb*) ² } ^1/2

[Table 1]

ΔEab (post-baking treatment - pre-baking treatment) Example 1 1.28 Example 2 1.27 Example 3 0.85 Example 4 1.36 Example 5 1.75 Example 6 0.94 Example 7 1.45 Example 8 1.39 Embodiment 9 1.12 Example 10 1.47 Embodiment 11 1.68 Example 12 1.27 Example 13 0.97 Embodiment 14 1.54 Embodiment 15 1.98 Example 16 1.76 Embodiment 17 1.64 Embodiment 18 1.44

Referring to Table 1, the color pattern substrates formed using the photosensitive resin compositions of Examples 1 to 18 of the present invention have a difference (ΔEab) in the transmission spectrum before and after the post-bake treatment of less than 3, which confirms high color stability and excellent heat resistance.

Contrast measurement

The substrate produced according to the above-mentioned substrate production method is placed between two polarizing plates using a contrast meter (CT-1, ZOENTECH). The brightness when the two polarizing plates are horizontal and when the two polarizing plates are orthogonal are measured, and the contrast is calculated using the following calculation formula 2.

[Calculation formula 2]

Contrast = Brightness when two polarizing films are horizontal / Brightness when two polarizing films are vertical

The contrast calculated by the above-mentioned calculation formula 2 was used to calculate the contrast improvement rate using the following calculation formula 3, and the result is recorded in the following Table 2.

[Calculation formula 3]

Contrast improvement rate = (contrast of the embodiment - contrast of comparative example 1, 2 or 4) / contrast of comparative example 1, 2 or 4 * 100

[Table 2]

With reference to Table 2, it can be confirmed that the contrast ratios of Examples 1 to 18 are improved by 220.47% to 532.38% compared to Comparative Example 1. It can also be confirmed that the contrast ratios of Examples 1 to 18 are improved by 136.48% to 329.57% compared to Comparative Example 2. It can also be confirmed that the contrast ratios of Examples 1 to 18 are improved by 197.83% to 510.43% compared to Comparative Example 4.

Fluorescence intensity measurement

The fluorescence intensity of the substrate produced according to the above-mentioned substrate production method was measured using a Sinco FS-2 fluorescence measuring device at room temperature (25° C.) with an excitation wavelength of 545 nm and an emission wavelength of 560 nm to 720 nm. The fluorescence intensity is shown in FIG. 1 .

According to FIG. 1 , it can be confirmed that the fluorescence intensity of Examples 6, 7, and 12 according to one embodiment of the present specification is lower than that of Comparative Examples 1 and 2, and that excellent contrast can be obtained without adding an additional dye.

Transmittance evaluation

The substrate produced by the above-mentioned substrate production method was post-baked at 230° C. for 20 minutes using a spectrometer (MCPD, Otsuka Corporation), thereby obtaining a transmittance spectrum in the visible light region ranging from 380 nm to 780 nm.

In particular, in the case of a blue color filter, when the maximum transmittance is high at 380 nm to 480 nm in visual x, visual y, and visual z, more excellent brightness can be exhibited.

Figure 2 shows visual x, visual y, and visual z.

Transmittance % (maximum transmittance % at 380nm ~ 480nm) Example 1 95.756 Example 7 92.906 Example 13 95.721 Comparative Example 3 88.528

With reference to Table 3, it can be seen that the maximum transmittances of Examples 1, 7, and 13 at 380 nm to 480 nm are higher than that of Comparative Example 3.
