By using the coloring composition of the present invention, a cured film having excellent heat resistance can be formed. In addition, generally, the higher the pigment concentration in the film, the more easily the heat resistance tends to decrease. However, even if the content of the pigment A in the total solid content is increased, the coloring composition of the present invention can form a cured film with excellent heat resistance. . Although the detailed mechanism is not clear, it is speculated that by using both pigment A and magenta dye, the magenta dye is adsorbed on the surface of pigment A, thereby suppressing the crystal growth accompanying the heating of pigment A, resulting in excellent heat resistance.

Pigment A has a structure in which the above-mentioned aromatic ring group is bonded to the diketopyrrolopyrrole skeleton. Therefore, by HOMO (Highest Occupied Molecular Orbital: Highest Occupied Molecular Orbital)-LUMO (Lowest Unoccupied Molecular Orbital: Lowest Unoccupied Molecular Orbital) The orbital) transition is prolonged and the transition moment increases. As a result, it is estimated that the molar extinction coefficient ε of the pigment A in the red wavelength region (for example, 450 to 600 nm) increases, and therefore the color price of red is high. In addition, the red color value of Pigment A is higher than that of conventional red pigments, so it is possible to achieve the desired spectrum with a blending amount less than the blending amount required to achieve the same spectral characteristics as conventional red pigments. The blending amount of components other than pigments can also be increased, and the degree of freedom in formulation design is high.

The pattern formation based on the photolithography method preferably includes the following processes: a process of forming a coloring composition layer on a support using the coloring composition of the present invention; a process of exposing the coloring composition layer into a pattern; and developing and removing coloring The process of forming patterns (pixels) on the unexposed parts of the composition layer. According to needs, the process of baking the colored composition layer (pre-baking process) and the process of baking the developed pattern (pixel) (post-baking process) can also be set.

In the step of forming the colored composition layer of the present invention, the colored composition is used to form the colored composition layer on the support. The support is not particularly limited, and can be appropriately selected according to the use. For example, a glass substrate, a silicon substrate, etc. can be mentioned, and a silicon substrate is preferable. In addition, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. may be formed on the silicon substrate. In addition, a black matrix that isolates each pixel is sometimes formed on a silicon substrate. In addition, in order to improve the adhesion with the upper layer, prevent the diffusion of substances, or flatten the surface of the substrate, an undercoat layer may be provided on the silicon substrate.

As a coating method of the coloring composition, a well-known method can be used. For example, the dropping method (drop casting); the slit coating method; the spray method; the roll coating method; the spin coating method (spin coating); the casting coating method; the slit spin coating method; the pre-wet method ( For example, the method described in Japanese Patent Laid-Open No. 2009-145395); inkjet (for example, on-demand, piezoelectric, thermal), nozzle jet and other jet printing, flexographic printing, screen printing, gravure printing , Reverse offset printing, metal mask printing and other printing methods; transfer method using molds, etc.; nano imprinting method, etc. There is no particular limitation on the applicable method in inkjet, for example, "Inkjet that can be promoted and used-Unlimited possibilities in patents-Issued in February 2005, Sumitbe Techon Research Co., Ltd." (Especially pages 115 to 133) or Japanese Patent Application Publication No. 2003-262716, Japanese Patent Application Publication No. 2003-185831, Japanese Patent Application Publication No. 2003-261827, Japanese Patent Application Publication No. 2012-126830, The method described in JP 2006-169325 A, etc. In addition, regarding the coating method of the coloring composition, refer to the descriptions of International Publication No. 2017/030174 and International Publication No. 2017/018419, and these contents are incorporated in this specification.

The colored composition layer formed on the support can be dried (pre-baked). In the case of manufacturing the film by a low-temperature process, pre-baking may not be performed. When performing pre-baking, the pre-baking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be set to 50°C or higher, or 80°C or higher, for example. The pre-baking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. The pre-baking can be performed with a hot plate, an oven, or the like.

＜＜Exposure process＞＞ Next, the colored composition layer is exposed into a pattern (exposure process). For example, by using a stepper exposure machine, a scanning exposure machine, etc., the colored composition layer is exposed through a mask having a predetermined mask pattern, thereby enabling exposure in a pattern. Thereby, the exposed part can be hardened.

Examples of radiation (light) that can be used for exposure include g-rays, i-rays, and the like. Moreover, 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 the like. KrF rays (wavelength 248 nm) are preferred. In addition, a long-wavelength light source of 300 nm or more can also be used.

In addition, at the time of exposure, light may be continuously irradiated for exposure, or pulsed irradiation may be used for exposure (pulse exposure). In addition, pulse exposure refers to an exposure method in which light is irradiated and paused repeatedly in a short-time (for example, millisecond or less) cycle. In pulse exposure, the pulse width is preferably 100 nanoseconds (ns) or less, more preferably 50 nanoseconds or less, and more preferably 30 nanoseconds or less.

The maximum instantaneous illuminance ^{is preferably 50,000,000 W/m 2} or more, more preferably 100,000,000 W/m ² or more, and even more preferably 200,000,000 W/m ² or more. In addition, the upper limit of the maximum instantaneous illuminance ^{is preferably 1000000000 W/m 2} or less, more preferably 800000000 W/m ² or less, and ^{more preferably 500000000 W/m 2} or less. In addition, the pulse width refers to the time during which light is irradiated in the pulse period. In addition, frequency refers to the number of pulse cycles per second. In addition, the maximum instantaneous illuminance refers to the average illuminance during the pulse period during which light is irradiated. In addition, the pulse period refers to a period in which the irradiation and pause of light in pulse exposure are regarded as one cycle.

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 . Regarding the oxygen concentration during exposure, it can be appropriately selected. In addition to performing in the atmosphere, for example, it can be in a low-oxygen environment with an oxygen concentration of 19% by volume or less (for example, 15% by volume, 5% by volume, or substantially no oxygen). Exposure can also be performed in a high oxygen environment (for example, 22 vol%, 30 vol%, or 50 vol%) where the oxygen concentration exceeds 21 vol%. In addition, the exposure illuminance can be appropriately set, and usually can be selected from the range of 1000 W/m ² to 100000 W/m ² (for example, 5000 W/m ² , 15000 W/m ² or 35000 W/m ² ). The oxygen concentration and the exposure illuminance can be appropriately combined with conditions. For example, the oxygen concentration can be 10% by ^{volume and the illuminance is 10,000 W/m 2} , the oxygen concentration is 35% by volume, and the illuminance is 20,000 W/m ² .

Next, development removes the unexposed part of the colored composition layer to form a pattern (pixel). The development and removal of the unexposed part of the coloring composition layer can be performed using a developer. Thereby, the coloring composition layer of the unexposed part in the exposure process is dissolved in the developing solution, and only the photohardened part remains. The temperature of the developer is preferably 20 to 30°C, for example. The development time is preferably 20 to 180 seconds. In addition, in order to improve the residue removal, the process of spinning off the developer every 60 seconds can be repeated several times, and then supplying a new developer.

Examples of the developer include an organic solvent, an alkaline developer, and the like, and an alkaline developer can be preferably used. As the alkaline developer, an alkaline aqueous solution (alkali developer) obtained by diluting the alkaline agent with pure water is preferred. Examples of alkali agents include polyurethane, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, and tetraethyl hydrogen. Ammonium oxide, tetrapropyl ammonium hydroxide, tetrabutyl ammonium hydroxide, ethyl trimethyl ammonium hydroxide, benzyl trimethyl ammonium hydroxide, dimethyl bis (2-hydroxyethyl) ammonium hydroxide, Choline, pyrrole, piperidine, 1,8-diazabicyclo[5.4.0]-7-undecene and other organic alkaline compounds or sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, silicon Inorganic alkaline compounds such as sodium salt and sodium metasilicate. In terms of environment and safety, alkali-based compounds with large molecular weights are preferred. 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. In addition, the developer may further contain a surfactant. As the surfactant, the above-mentioned surfactants can be exemplified, and nonionic surfactants are preferred. From the viewpoint of convenient transportation or storage, the developer can be temporarily produced as a concentrated solution, and diluted to a desired concentration during use. The dilution ratio is not particularly limited, and can be set in the range of 1.5 to 100 times, for example. Furthermore, it is also preferable to wash (rinse) with pure water after development. In addition, rinsing is preferably performed by supplying a rinsing liquid to the developed coloring composition layer while rotating the support on which the developed coloring composition layer is formed. Moreover, it is also preferable to perform it by moving the nozzle which discharges a rinse liquid from the center part of a support body to the peripheral part of a support body. At this time, when moving from the center portion of the support body of the nozzle to the peripheral edge portion, the nozzle can be moved while gradually reducing the movement speed of the nozzle. By performing rinsing in this way, the in-plane deviation of rinsing can be suppressed. In addition, the same effect can be obtained by gradually reducing the rotation speed of the support while moving the nozzle from the center of the support to the peripheral edge.

After development, it is preferable to perform additional exposure treatment and heat treatment (post-baking) after drying. Additional exposure treatment and post-baking are curing treatments after development for making a fully cured product. The heating temperature in the post-baking is, for example, preferably 100 to 240°C, more preferably 200 to 240°C. The developed film can be post-baked in a continuous or intermittent manner using a heating mechanism such as a heating plate, a convection oven (hot air circulation type dryer), or a high-frequency heater so as to meet the above-mentioned conditions. In the case of performing additional exposure processing, the light used for exposure is preferably light with a wavelength of 400 nm or less. In addition, the additional exposure processing can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

The pattern formation based on the dry etching method preferably includes the following process: the coloring composition of the present invention is used to form a coloring composition layer on a support, and the entire coloring composition layer is hardened to form a hardened layer; The process of forming a photoresist layer on the hardened layer; the process of exposing the photoresist layer into a pattern and then developing to form a resist pattern; and using the resist pattern as a mask and using an etching gas on the hardened layer Perform dry etching process. When forming the photoresist layer, it is better to further perform a pre-baking treatment. In particular, as a process for forming the photoresist layer, a form of performing a heat treatment after exposure and a heat treatment after development (post-baking treatment) is preferable. Regarding the pattern formation by the dry etching method, reference can be made to the description of paragraph numbers 0010 to 0067 of JP 2013-064993 A, and this content is incorporated in this specification.
