Moreover, about the coating method of a coloring composition, international publication 2017/030174 and description of international publication 2017/018419 can be considered into consideration, and these content is integrated in this specification.

The coloring composition layer formed on the support may be dried (prebaked). When manufacturing a film by a low-temperature process, it is not necessary to perform prebaking. In the case of prebaking, the prebaking temperature is preferably 150°C or lower, more preferably 120°C or lower, and still more preferably 110°C or lower.

Next, the coloring composition layer is exposed in a pattern (exposure step). For example, the coloring composition layer can be exposed in a pattern by exposing through a mask having a predetermined mask pattern using a stepper exposure machine, a scanner exposure machine, or the like. In this way, the exposed portion can be cured.

Examples of the radiation (light) that can be used during exposure include g-ray and i-ray.

In addition, a long-wave light source of 300 nm or more can also be used.

Moreover, at the time of exposure, you may expose by irradiating light continuously, and you may expose by irradiating and exposing light pulsewise (pulse exposure). Further, pulse exposure is an exposure method of a system in which light irradiation and pause are repeatedly exposed in cycles of a short time (eg, millisecond level or less).

The irradiation amount (exposure amount) is, for example, 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, and besides performing under atmospheric conditions, for example, in a low-oxygen atmosphere in which the oxygen concentration is 19% by volume or less (eg, 15% by volume, 5% by volume, or substantially It may be exposed in an oxygen-free atmosphere) or in a high-oxygen atmosphere in which the oxygen concentration exceeds 21% by volume (for example, 22% by volume, 30% by volume, or 50% by volume). In addition, the exposure illuminance can be set appropriately, and can be selected from the range of usually 1000 W/m ² to 100000 W/m ² (for example, 5000 W/m ² , 15000 W/m ² , or 35000 W/m ² ). . Oxygen concentration and exposure illuminance may suitably combine conditions, and, for example, an oxygen concentration of 10 vol% and an illuminance of 10000 W/m ² , an oxygen concentration of 35 vol% and an illuminance of 20000 W/m ² , and the like.

Next, the unexposed portion of the coloring composition layer is removed from development to form a pattern (pixel). The development and removal of the unexposed part of the coloring composition layer can be performed using a developing solution. Thereby, the coloring composition layer of the unexposed part in an exposure process is eluted to a developing solution, and only a photocured part remains. As for the temperature of a developing solution, 20-30 degreeC is preferable, for example. As for developing time, 20 to 180 second is preferable. Further, in order to improve residue removability, the process of shaking off the developer every 60 seconds and supplying a new developer may be repeated several more times.

The alkaline agent is preferably a compound having a large molecular weight from the viewpoint of environment and safety. 0.001-10 mass % is preferable, and, as for the density|concentration of the alkali agent of alkaline aqueous solution, 0.01-1 mass % is more preferable. Moreover, the developing solution may further contain a surfactant. The developing solution may be once prepared as a concentrated solution and diluted to a concentration necessary for use from the viewpoint of transportation or storage convenience. Although the dilution factor is not particularly limited, it can be set, for example, in the range of 1.5 to 100 times. Moreover, it is also preferable to wash (rinse) with pure water after image development. Further, the rinse is preferably performed by supplying a rinse liquid to the colored composition layer after development while rotating the support on which the colored composition layer after development is formed. It is also preferable to move the nozzle for discharging the rinse liquid from the center of the support to the periphery of the support. At this time, when the nozzle is moved from the central portion of the support body to the peripheral edge portion, the nozzle may be moved while gradually lowering the moving speed. By performing the rinse in this way, the in-plane variation of the rinse can be suppressed. Also, the same effect can be obtained by gradually lowering the rotational speed of the support while moving the nozzle from the center of the support to the periphery.

It is preferable to perform additional exposure treatment or heat treatment (post-bake) after drying after development. Additional exposure treatment and post-baking are curing treatments after development to complete curing. The heating temperature in the post-baking is, for example, preferably 100 to 240°C, and more preferably 200 to 240°C. Post-baking can be performed continuously or batchwise using a heating means such as a hot plate, a convection oven (hot air circulating dryer), or a high-frequency heater so that the developed film meets the above conditions. When performing additional exposure processing, it is preferable that the light used for exposure is light with a wavelength of 400 nm or less. Moreover, you may perform additional exposure processing by the method described in Korean Unexamined Patent Publication No. 10-2017-0122130.

(Example 1001)

1 mass part of compound (a-1), 8 mass parts of acetone, and 0.3 mass part of activated carbon (Osaka Gas Chemical Co., Ltd. make) were added, and it stirred for 10 minutes. The activated carbon was separated by filtration using celite, then concentrated, and crystallized by adding 6 parts by mass of water. After separating the produced solid by filtration, it was washed with 5 parts by mass of water. The resulting solid was air dried at 50°C to obtain 0.9 parts by mass of compound (a-1a), which is a purified product of compound (a-1). In Synthesis Example 1, compound (Y-1a) was synthesized using compound (a-1a) instead of compound (a-1).

In dispersion liquid 1, dispersion liquid 1a was prepared similarly except having used compound (Y-1a) instead of compound (Y-1).
