[0012] The colored composition of the present invention exhibits good storage stability and can suppress increases in viscosity over time. The reason for these effects is presumed to be as follows: Diketopyrrolopyrrole pigments and isoindoline pigments tend to aggregate in colored compositions, and colored compositions using these pigments tend to increase in viscosity over time due to pigment aggregation during storage. However, the colored composition of the present invention uses three or more diketopyrrolopyrrole pigments and isoindoline pigments as colorants, which is presumed to reduce the crystallinity between the pigments and improve the dispersibility of the pigments in the colored composition. For this reason, the colored composition of the present invention is presumed to have excellent storage stability.

[0013] The colored composition of the present invention, by using three or more diketopyrrolopyrrole pigments and an isoindoline pigment in combination as colorants, can form a film with excellent spectral properties (preferably red spectral properties).

These compounds may be used as solvents when manufacturing the various components used in colored compositions, and may be mixed into the colored compositions as residual solvents. From the standpoint of human safety and environmental considerations, it is preferable to reduce these substances as much as possible. One method for reducing environmentally regulated substances is to heat or reduce the pressure in the system to above the boiling point of the environmentally regulated substance and distillate it off the system. Furthermore, when removing small amounts of environmentally regulated substances by distillation, it is useful to azeotrope with a solvent having a boiling point equivalent to that of the solvent in question in order to increase efficiency. In addition, if the mixture contains compounds that exhibit radical polymerization, polymerization inhibitors may be added during reduced-pressure distillation to suppress the progression of radical polymerization reactions and the resulting crosslinking between molecules.

The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. It is also preferably 30 to 80° when measured with water.

[0211] Known methods can be used for applying the colored composition. For example, drop casting; slit coating; spray coating; roll coating; spin coating; casting; slit and spin coating; pre-wetting (for example, the method described in Japanese Patent Application Publication No. 2009-145395); various printing methods such as inkjet (for example, on-demand, piezo, and thermal), nozzle jet printing, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing; transfer methods using molds, etc.; and nanoimprint methods. In addition, the application method described in paragraph 0207 of International Publication No. 2022 / 085485 can also be used.

[0212] The colored composition layer formed on the support may be dried (pre-baked). When pre-baking is performed, the pre-baking temperature is preferably 80°C or lower, more preferably 70°C or lower, even more preferably 60°C or lower, and particularly preferably 50°C or lower. The lower limit can be, for example, 40°C or higher. The pre-baking time is preferably 10 to 3600 seconds. Pre-baking can be performed using a hot plate, oven, etc.

[0213] Next, the colored composition layer is exposed in a pattern (exposure step). For example, the colored composition layer can be exposed in a pattern by using a stepper exposure machine or a scanner exposure machine to expose it through a mask having a predetermined mask pattern. This allows the exposed areas to be cured.

[0214] Examples of radiation (light) that can be used during exposure include g-rays and i-rays. 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 with a wavelength of 300 nm or less include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Long-wave light sources with wavelengths of 300 nm or more can also be used.

[0215] During exposure, the light may be irradiated continuously or pulsed (pulsed exposure). Pulsed exposure is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, at the millisecond level or less).

[0216] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm². ２ This is preferable. The lower limit is 0.05 J / cm². ２ Preferably, it is 0.2 J / cm². ２ It is more preferable that the value be greater than or equal to 0.5 J / cm². ２ It is even more preferable that the value be greater than or equal to 0.8 J / cm². ２ It is even more preferable that the above is true, specifically 1.0 J / cm². ２ It is even more preferable that the above is true. The upper limit is 2.0 J / cm². ２ Preferably, it is 1.5 J / cm ２ The following is more preferable. Furthermore, the exposure intensity can be set as appropriate, for example, 50 mW / cm². ２ ~10W / cm ２ It is preferable that the lower limit of exposure illuminance is 500 mW / cm². ２ Preferably, it is 800 mW / cm² or higher. ２ It is more preferable that the level be greater than or equal to 1000 mW / cm². ２ It is even more preferable that the above conditions are met. The upper limit of the exposure illuminance is 10 W / cm². ２ Preferably, it is 7 W / cm² ２ It is more preferable that the following conditions are met: 5 W / cm ２ The following is even more preferable:

[0217] The oxygen concentration during exposure can be appropriately selected. In addition to exposure in air, exposure may be carried out in a low-oxygen atmosphere with an oxygen concentration of 19 vol% or less (e.g., 15 vol%, 5 vol%, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration exceeding 21 vol% (e.g., 22 vol%, 30 vol%, or 50 vol%). The oxygen concentration and exposure illuminance may be combined as appropriate. For example, an oxygen concentration of 10 vol% and an illuminance of 1 W / cm² may be used. ２At an oxygen concentration of 35% by volume and an illuminance of 2 W / cm², ２ This can be done as follows.

[0218] In the exposure process, light with a wavelength between 350 nm and 380 nm (preferably i-line) is applied at a rate of 1 J / cm². ２ It is also preferable to expose the material with the above exposure levels. By exposing it in this way, the colored composition layer can be sufficiently cured.

[0219] Next, the colored composition layer after exposure is developed. That is, the unexposed parts of the colored composition layer are developed and removed to form a pattern (pixel). The development and removal of the unexposed parts of the colored composition layer can be done using a developer. This causes the unexposed parts of the colored composition layer in the exposure process to dissolve in the developer, leaving only the photocured parts. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve the ability to remove residue, the developer may be emptied every 60 seconds, and the process of supplying fresh developer may be repeated several times.

[0220] Examples of developing solutions include organic solvents and alkaline developers, with alkaline developers being preferred. For the developing solution and the rinsing method after development, the developing solution and rinsing method described in paragraph 0214 of International Publication No. 2022 / 085485 may be used.

[0221] It is also preferable to perform additional exposure or heat treatment (post-bake) after development and drying. Additional exposure and post-bake are curing treatments after development to ensure complete hardening.

[0222] When post-baking is performed, the heating temperature is preferably 150°C or lower. The upper limit of the heating temperature is more preferably 120°C or lower, and even more preferably 100°C or lower. The lower limit of the heating temperature is not particularly limited as long as the hardening of the film is promoted, but it is preferably 50°C or higher, and more preferably 75°C or higher. The heating time is preferably 1 minute or more, more preferably 5 minutes or more, and even more preferably 10 minutes or more. There is no particular upper limit, but from the viewpoint of productivity, it is preferably 20 minutes or less. Post-baking can also be performed in an inert gas atmosphere. According to this embodiment, thermal polymerization can proceed with very high efficiency without being inhibited by oxygen, and even if pixels are manufactured at a temperature of 150°C or lower throughout the entire process, pixels with good flatness and excellent properties such as light resistance can be manufactured. Examples of inert gases include nitrogen gas, argon gas, and helium gas, with nitrogen gas being preferred. The oxygen concentration during post-baking is preferably 100 ppm or lower.

[0223] When performing additional exposure processing, it is preferable to expose the layer by irradiating it with light with a wavelength of 254 to 350 nm. In a more preferable embodiment, the step of exposing the colored composition layer in a pattern (exposure before development) is performed by irradiating the colored composition layer with light with a wavelength greater than 350 nm and less than or equal to 380 nm (preferably light with a wavelength of 355 to 370 nm, more preferably i-line light), and the additional exposure processing (exposure after development) is performed by irradiating the developed colored composition layer with light with a wavelength of 254 to 350 nm (preferably light with a wavelength of 254 nm). According to this embodiment, the colored composition layer can be moderately cured in the first exposure (exposure before development), and the entire colored composition layer can be almost completely cured in the next exposure (exposure after development). As a result, even under low temperature conditions, the colored composition layer can be sufficiently cured, and pixels with excellent properties such as light resistance, adhesion, and rectangularity can be formed.

[0224] Post-development exposure can be performed, for example, using an ultraviolet photoresist curing apparatus. The ultraviolet photoresist curing apparatus may irradiate the material with light of wavelengths of, for example, 254 to 350 nm, as well as other types of light (e.g., i-lights).

[0225] Furthermore, when additional exposure processing is performed, a continuous spectrum is preferred as the exposure source spectrum, and from the viewpoint of improving the light resistance and adhesion to the substrate of the obtained film, it is preferable that the spectrum distribution is different from that of the exposure before development. For example, the following radiations (a) to (c) can be cited. Among these, radiation (b) or (c) is preferred in that it can achieve a higher level of improvement in the light resistance and adhesion to the substrate of the obtained film. Also, when the colorant contains a dye, the dye generally absorbs ultraviolet light or short-wavelength visible light and may photodegrade, so radiation (c) which has fewer high-intensity components on the short-wavelength side is preferred. (a) Radiation having a different spectrum distribution from that of the exposure before development, wherein the peak intensity at a wavelength of 313 nm (j-line) is 1 / 6 or more and less than 1 / 3 of the peak intensity at a wavelength of 365 nm (i-line). (b) Radiation having a different spectrum distribution from that of the exposure before development, wherein the peak intensity at a wavelength of 313 nm (j-line) is 1 / 3 or more of the peak intensity at a wavelength of 365 nm (i-line). (c) Radiation having a different spectral distribution from that of exposure before development, comprising wavelengths of 405 nm (h-ray) and 436 nm (g-ray), wherein the peak intensities at wavelengths of 313 nm (j-ray) and 365 nm (i-ray) are 1 / 4 or less, preferably 1 / 10 or less, and more preferably 1 / 20 of the smaller peak intensity between the peak intensity at wavelengths of 405 nm (h-ray) and 436 nm (g-ray). In this case, the exposure before development is preferably radiation including wavelengths of 365 nm (i-line), 405 nm (h-line), and 436 nm (g-line), wherein the peak intensity at wavelength 313 nm (j-line) is less than 1 / 6 of the peak intensity at wavelength 365 nm (i-line).

[0226] Radiation exhibiting such spectral characteristics can be obtained, for example, by using a light source exhibiting the spectral characteristics described above, or by transmitting radiation from a high-pressure mercury lamp through an ultraviolet cut filter or bandbus filter.

[0227] The exposure dose after development is 0.03 to 4.0 J / cm². ２ Preferably, 0.05 to 3.5 J / cm ２ This is more preferable. The difference between the wavelength of light used for exposure before development and the wavelength of light used for exposure after development is preferably 200 nm or less, and more preferably 100 to 150 nm.

[0229] The device has a substrate on which multiple photodiodes and transfer electrodes made of polysilicon or the like constitute the light-receiving area of ​​a solid-state image sensor (such as a CCD (charge-coupled device) image sensor or a CMOS (complementary metal-oxide-semiconductor) image sensor), a light-shielding film with an opening only for the light-receiving portion of the photodiode is placed on the photodiode and transfer electrodes, a device protection film made of silicon nitride or the like is formed on the light-shielding film to cover the entire surface of the light-shielding film and the light-receiving portion of the photodiode, and a color filter is placed on the device protection film. Furthermore, the device may have a configuration in which a light-gathering means (for example, a microlens; the same applies hereinafter) is placed on the device protection film and below the color filter (on the side closer to the substrate), or a configuration in which the light-gathering means is placed on the color filter. The color filter may also have a structure in which each colored pixel is embedded in a space partitioned by partitions, for example in a grid pattern. In this case, it is preferable that the partitions have a lower refractive index than each colored pixel. Examples of imaging devices having such a structure include those described in Japanese Patent Publication No. 2012-227478, Japanese Patent Publication No. 2014-179577, and International Publication No. 2018 / 043654. Furthermore, as shown in Japanese Patent Publication No. 2019-211559, the light resistance may be improved by providing an ultraviolet absorption layer within the structure of the solid-state image sensor. The imaging device equipped with the solid-state image sensor of the present invention can be used not only in digital cameras and electronic devices with imaging functions (such as mobile phones), but also in in-vehicle cameras and surveillance cameras.
