The colored composition layer formed on the support may be dried (prebaked). When the film is manufactured by a low-temperature process, pre-baking is not required. When prebaking is performed, the prebaking temperature is preferably 150°C or lower, more preferably 120°C or lower, and further preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, or 80°C or higher. The prebaking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and further preferably 80 to 220 seconds. Prebaking can be performed using a heating plate, oven, etc.

Next, the colored composition layer is exposed in a pattern (exposure step). For example, a stepper exposure machine, a scanning exposure machine, or the like is used to expose the colored composition layer through a mask having a predetermined mask pattern, whereby the colored composition layer can be exposed in a pattern. Thereby, the exposed portion can be hardened.

Examples of radiation (light) that can be used during exposure include g-rays, i-rays, and the like. In addition, light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) can also be used. Examples of light having a wavelength of 300 nm or less include KrF rays (wavelength: 248 nm), ArF rays (wavelength: 193 nm), and KrF rays (wavelength: 248 nm) are preferred. In addition, a long-wavelength light source of 300 nm or more can also be used. As a light source, it is possible to use electrodeless UV lamp systems, mixed curing of UV and infrared rays.

In addition, during exposure, light may be continuously irradiated for exposure, or pulse irradiation may be performed for exposure (pulse exposure). In addition, pulse exposure refers to an exposure method in which light is irradiated and paused repeatedly to perform exposure in a short period of time (for example, milliseconds or less).

For example, the irradiation amount (exposure amount) is preferably 0.03 to 2.5 J/cm ² , and more preferably 0.05 to 1.0 J/cm ² . The oxygen concentration during exposure can be appropriately selected. In addition to being performed in the atmosphere, for example, it can also be performed in a low-oxygen environment with an oxygen concentration of 19 volume % or less (for example, 15 volume %, 5 volume %, or substantially no oxygen). Exposure can also be carried out in a high oxygen environment with an oxygen concentration exceeding 21 volume % (for example, 22 volume %, 30 volume % or 50 volume %). In addition, the exposure illuminance can be appropriately set, and can usually be selected from the range of 1000W/m ² to 100000W/m ² (for example, 5000W/m ² , 15000W/m ² or 35000W/m ² ). The conditions of oxygen concentration and exposure illuminance can be combined appropriately. For example, the oxygen concentration can be 10 volume % and the illuminance is 10000 W/m ² , the oxygen concentration can be 35 volume % and the illuminance is 20000 W/m ² , etc.

Next, the unexposed portion of the colored composition layer is removed by development to form a pattern (pixel).

For example, the temperature of the developer is preferably 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, in order to improve the residue removal performance, the step of shaking off the developer every 60 seconds and supplying new developer may be repeated several times.

From an environmental and safety perspective, it is better for the alkaline agent to be a compound with a large molecular weight. The concentration of the alkali agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. Moreover, the developer may further contain a surfactant. From the viewpoint of ease of transportation or storage, the developer can be first produced as a concentrated solution and then diluted to a desired concentration when used. The dilution ratio is not particularly limited, but can be set in the range of 1.5 to 100 times, for example. In addition, it is also preferable to wash (rinse) with pure water after development. Furthermore, it is preferable to perform rinsing by supplying a rinsing liquid to the developed colored composition layer while rotating the support on which the developed colored composition layer is formed. It is also preferable to move the nozzle that sprays the rinse liquid from the center of the support body to the peripheral edge of the support body. At this time, when moving the nozzle from the center part of the support body to the peripheral part, the moving speed of the nozzle may be gradually reduced while moving the nozzle. By performing flushing in this manner, in-plane unevenness of flushing can be suppressed. In addition, the same effect can also be obtained by gradually reducing the rotation speed of the support body while moving the nozzle from the center part of the support body to the peripheral part.

After development, it is preferable to perform additional exposure processing or heat processing (post-baking) after drying. The additional exposure process or post-baking is a hardening process after development for complete hardening. The heating temperature in post-baking is, for example, preferably 100 to 240°C, more preferably 200 to 240°C. In order to achieve the above conditions, heating methods such as heating plates, convection ovens (hot air circulation dryers), and high-frequency heating machines can be used to post-bake the developed film in a continuous or intermittent manner. When performing additional exposure processing, it is preferable that the light used for exposure is light with a wavelength of 400 nm or less. In addition, the additional exposure process can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

<Evaluation of Contrast> The base layer forming composition (CT-4000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was applied on the glass substrate by spin coating, and heated at 220°C for 1 hour using a hot plate. A base layer with a thickness of 0.1 μm was formed. On the glass substrate with the base layer, each coloring composition was applied by spin coating so that the film thickness after post-baking became 0.5 μm, and then prebaked at 100° C. for 2 minutes using a hot plate. After prebaking, the coating film was exposed using an i-ray stepper exposure device (FPA-3000i5+, manufactured by Canon Inc.) at an exposure dose of 500 mJ/cm ² with a wavelength of 365 nm. Next, post-baking was performed at 220° C. for 5 minutes using a hot plate to form a film. The obtained film was sandwiched between two polarizing plates, and the brightness of the transmitted light when the polarizing axes of the polarizing plates were parallel and perpendicular was measured using a color luminance meter (color luminance meter BM-7 manufactured by TOPCON CORPORATION). The contrast value (brightness when parallel/brightness when perpendicular) was obtained by dividing the luminance when parallel by the luminance when perpendicular, and the contrast was evaluated based on the following evaluation criteria. The higher the contrast value, the better the performance as a color filter. (Evaluation criteria) AA: The contrast value is 20,000 or more A: The contrast value is 18,000 or more and less than 20,000 B: The contrast value is 15,000 or more and less than 18,000 C: The contrast value is 10,000 or more but less than 15,000 D: The contrast value is less than 15,000 10000

＜Evaluation of moisture resistance＞ At a constant temperature and humidity of 85°C and a humidity of 85%, the film produced above was exposed to a humidity resistance test for 1000 hours. Then, a spectrophotometer (U-4100, manufactured by Hitachi High-Tech Corporation) was used to measure the transmittance in the wavelength range of 400 to 700 nm before and after the moisture resistance test of the film, and the change rate of the transmittance for each measured wavelength was calculated. , the maximum value (ΔTmax) of the transmittance change rate was determined, and the moisture resistance was evaluated based on the following criteria. The transmittance was measured five times for each sample, and the average of the three results after excluding the maximum value and the minimum value was used. In addition, the maximum value of the change amount of transmittance refers to the change amount at the wavelength where the change amount of transmittance of the film before and after the moisture resistance test is the largest in the wavelength range of 400 to 700 nm. (Evaluation criteria) A: ΔTmax is less than 1% B: ΔTmax exceeds 1% and is less than 1.5% C: ΔTmax exceeds 1.5% and is less than 2.0% D: ΔTmax exceeds 2.0%

As shown in the above table, the Examples were excellent in contrast and moisture resistance compared with Comparative Examples.

Regarding the colored compositions of Examples 3, 4, 8 and Comparative Example 2, a heat resistance test was performed by heating the film produced in the contrast evaluation using a hot plate at 260° C. for 10 minutes. As a result of observation using a scanning electron microscope (magnification: 30,000 times), no foreign matter was observed in the films obtained using the colored compositions of Examples 3, 4, and 8, and the contrast was good without changing before and after the heat resistance test. In particular, in the films obtained using the colored compositions of Examples 3 and 8, the contrast did not change even if the heating time was extended to 15 minutes. On the other hand, in the film obtained using the colored composition of Comparative Example 2, foreign matter was observed, and the contrast also decreased.

Regarding the colored compositions of Examples 6, 11, 14 and Comparative Example 1, the films prepared for contrast evaluation were irradiated with light of 100,000 lux using an Xe lamp through an ultraviolet cut filter for 5 hours, and then The ΔEab value of the color difference before and after light irradiation was measured using a meter (MCPD-1000, manufactured by Otsuka Electronics Co., Ltd.). The smaller the ΔEab value, the better the light resistance. In addition, the ΔEab value is a value calculated from the color difference formula based on the CIE1976 (L*, a*, b*) space color system (Color Science Association of Japan (Color Science Association of Japan) newly compiled color science handbook (1985) ) p.266). In the films obtained using the colored compositions of Examples 6, 11, and 14, the ΔEab value was less than 2.5, and the light resistance was good. In particular, in the film obtained using the colored composition of Example 11, the ΔEab value was less than 2.0, and the light resistance was better. On the other hand, the film obtained using the colored composition of Comparative Example 1 had a ΔEab value of 10 or more, indicating poor light resistance.

The colored compositions of Example 4 and Example 8 containing a resin (containing a repeating unit having a maleimide structure) were made into films on a glass substrate in the same manner as in the contrast evaluation, and were treated with 300 The heating plate was heated at ℃. The color difference (ΔE*ab value) before and after heating was measured using a colorimeter MCPD-3000 (manufactured by Otsuka Electronics Co., Ltd.) and the heat resistance was evaluated. As a result, the ΔE*ab value did not reach 1, which was considered good. On the other hand, when the heat resistance of the colored composition of Comparative Example 1 was evaluated by the same operation, the ΔE*ab value was 5 or more, which poses a practical problem.

The colored compositions of Examples 1, 2, 3, and 7 containing resins (containing a repeating unit having a phenyl group) were put into a sealed container and stored at a temperature of 50° C. for 3 days. The stored colored composition was applied on a glass substrate by spin coating, and then heated at 100° C. for 2 minutes using a hot plate to obtain a composition layer. The obtained composition layer was exposed using an i-ray stepper at an exposure dose of 500 mJ/cm ² . Next, the exposed coating layer was further hardened using a hot plate at 220° C. for 5 minutes to obtain a film with a thickness of 0.7 μm. The obtained film was observed with an optical microscope and the number of foreign matter defects produced in an area of 100 μm × 100 μm was calculated. The number of foreign matter defects was less than 5, which was considered good. On the other hand, the colored composition of Comparative Example 1 was evaluated for foreign matter defects through the same operation. As a result, the number of foreign matter defects was 1,000 or more, which poses a practical problem.
