[0001] The present invention relates to compositions comprising pyrrolopyrrole compounds. Furthermore, the present invention relates to films, optical filters, solid-state image sensors, image display devices, infrared sensors, and camera modules using the aforementioned compositions. The present invention also relates to pyrrolopyrrole compounds. [Background technology]

[0002] Video cameras, digital still cameras, and mobile phones with camera functions use solid-state image sensors for color images, such as CCDs (charge-coupled devices) and CMOS (complementary metal-oxide-semiconductor) sensors. These solid-state image sensors use silicon photodiodes, which are sensitive to infrared light, in their light-receiving sections. For this reason, infrared cut filters are sometimes provided to correct the visual sensitivity.

[0003] Infrared cut filters are manufactured using compositions containing infrared absorbing dyes. Examples of infrared absorbing dyes include pyrrolopyrrole compounds.

[0004] On the other hand, Non-Patent Document 1 describes a compound with the following structure as having strong absorption in the visible and near-infrared regions. Furthermore, Non-Patent Document 1 uses a compound with the following structure as the active layer of an organic thin-film solar cell. [ka] [Prior art documents] [Patent Documents]

Furthermore, according to the present invention, it is possible to provide films, optical filters, solid-state image sensors, image display devices, infrared sensors, camera modules, and compounds. [Brief explanation of the drawing]

[0010] [Figure 1] This is a schematic diagram showing one embodiment of an infrared sensor. [Modes for carrying out the invention]

[0011] The details of the present invention will be described in detail below. In this specification, "~" is used to mean that the numbers before and after it include the lower and upper limits, respectively. In this specification, when groups (atomic groups) are not specified as substituted or unsubstituted, the notation includes both groups (atomic groups) with and without substituents. For example, "alkyl group" includes not only unsubstituted alkyl groups but also substituted alkyl groups. In this specification, "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams, unless otherwise specified. Examples of light used for exposure include the emission spectrum of mercury lamps, far ultraviolet light represented by excimer lasers, extreme ultraviolet (EUV) light, X-rays, electron beams, and other active light or radiation. In this specification, "(meth)acrylate" refers to both acrylate and methacrylate, or either of them; "(meth)acrylic" refers to both acrylic and methacrylic, or either of them; and "(meth)acryloyl" refers to both acryloyl and methacryloyl, or either of them. In this specification, weight-average molecular weight and number-average molecular weight are defined as polystyrene equivalent values ​​measured by gel permeation chromatography (GPC). In this specification, Me in the chemical formula represents a methyl group, Et represents an ethyl group, Bu represents a butyl group, and Ph represents a phenyl group. In this specification, infrared radiation refers to light (electromagnetic waves) with a wavelength of 700 to 2500 nm. In this specification, total solids refers to the total mass of the components of the composition excluding the solvent. In this specification, "pigment" means a compound that is poorly soluble in solvents. In this specification, the term "process" includes not only independent processes but also any process that cannot be clearly distinguished from other processes, as long as its intended function is achieved.

[0012] <Composition> The composition of the present invention is characterized by comprising a compound represented by formula (1) and a curable compound.

[0013] The composition of the present invention makes it possible to form a film with excellent light resistance. Although the detailed reason for this effect is unknown, the compound represented by formula (1) has a structure in which multiple pyrrolopyrrole rings are linked by n-valent conjugated linking groups containing aromatic heterocyclic groups. Therefore, it is presumed that when forming a film using a composition containing a curable compound, associations of the compound represented by formula (1) are easily formed in the film during film formation. It is presumed that the formation of such associations in the film improves the light resistance of the resulting film. Furthermore, the formation of these associations in the film can also improve the heat resistance of the resulting film. In addition, because the compound represented by formula (1) has a broad infrared absorption bandwidth, it is also possible to form a film that can block infrared rays across a wide wavelength range by using the composition of the present invention.

[0014] The composition of the present invention can be used as a composition for optical filters. Examples of optical filters include infrared cut filters and infrared transmission filters.

[0015] When the composition of the present invention is used as a composition for forming an infrared cut filter, as the compound represented by the formula (1), X in the formula (1) 1 and X 2 It is preferable to use a compound having a structure in which is C-CN. X in the formula (1) 1 and X 2 A compound having a structure in which is C-CN is a compound excellent in visible transparency and infrared shielding properties. By using a composition containing such a compound, an infrared cut filter having spectroscopic properties excellent in visible transparency and infrared shielding properties can be formed. Further, when the composition of the present invention is used as a composition for forming an infrared transmission filter, the composition of the present invention preferably contains a colorant. Further, as the compound represented by the formula (1), X in the formula (1) 1 and X 2 It is preferable to use a compound having a structure in which is N. X in the formula (1) 1 and X 2 Since a compound having a structure in which is N has absorption in each of the infrared region and the visible region, by using such a compound in combination with a colorant, visible light can be blocked and infrared rays having a wavelength longer than a specific wavelength can be transmitted. An infrared transmission filter having the spectroscopic properties can be formed.

[0016] Hereinafter, each component used in the composition of the present invention will be described.

[0017] <<Compound represented by formula (1) (specific compound)>> The composition of the present invention contains a compound represented by the formula (1) (hereinafter, also referred to as a specific compound).

[0180] <Method for preparing the composition> The composition of the present invention can be prepared by mixing the aforementioned components. When preparing the composition, all components may be dissolved or dispersed simultaneously in a solvent, or, if necessary, two or more solutions or dispersions containing the components in appropriate proportions may be prepared in advance and mixed at the time of use (application) to prepare the composition.

[0181] The preparation of the composition may include a process for dispersing the pigment.

[0182] In preparing the composition, it is preferable to filter the composition with a filter for purposes such as removing foreign matter and reducing defects. Any filter that has been conventionally used for filtration purposes can be used without particular limitations. For example, filters made of materials such as fluororesins such as polytetrafluoroethylene (PTFE), polyamide resins such as nylon (e.g., nylon-6, nylon-6,6), and polyolefin resins such as polyethylene and polypropylene (PP) (including high-density and ultra-high molecular weight polyolefin resins) can be used. Among these materials, polypropylene (including high-density polypropylene) and nylon are preferred.

[0183] The pore size of the filter is preferably 0.01 to 7.0 μm, more preferably 0.01 to 3.0 μm, and even more preferably 0.05 to 0.5 μm. If the filter pore size is within the above range, fine foreign matter can be removed more reliably. The nominal value of the filter pore size can be referred to from the filter manufacturer. Various filters provided by Nippon Pall Co., Ltd. (DFA4201NIEY, DFA4201NAEY, DFA4201J006P, etc.), Advantec Toyo Co., Ltd., Nippon Integris Co., Ltd.

Commercially available products include the SBP type series (SBP008, etc.), TPR type series (TPR002, TPR005, etc.), and SHPX type series (SHPX003, etc.) from Rokitechno Co., Ltd.

[0185] When using filters, different filters (for example, a first filter and a second filter) may be combined. In this case, filtration with each filter may be performed only once or two or more times. Filters with different pore sizes within the range described above may also be combined. Furthermore, filtration with the first filter may be performed only on the dispersion, and after mixing in other components, filtration with the second filter may be performed.

[0193] The film of the present invention can also be used in combination with a color filter containing a chromatic coloring agent. The color filter can be manufactured using a coloring composition containing a chromatic coloring agent. When the film of the present invention is used as an infrared cut filter and in combination with a color filter, it is preferable that the color filter is positioned on the optical path of the film of the present invention. For example, it is preferable to laminate the film of the present invention and the color filter to form a laminate. In the laminate, the film of the present invention and the color filter may or may not be adjacent in the thickness direction. If the film of the present invention and the color filter are not adjacent in the thickness direction, the film of the present invention may be formed on a support other than the support on which the color filter is formed, and other components constituting a solid-state image sensor (e.g., microlenses, planarization layers, etc.) may be interposed between the film of the present invention and the color filter.

[0194] The film of the present invention can be used in various devices such as solid-state image sensors like CCDs (charge-coupled devices) and CMOS (complementary metal-oxide-semiconductor) sensors, as well as infrared sensors and image display devices.

[0195] <Memory manufacturing method> The film of the present invention can be manufactured by a process of applying the composition of the present invention.

[0196] Examples of supports include those mentioned above. Known methods can be used for coating the 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 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. The application method for inkjet printing is not particularly limited, and examples include the method shown in "Expanding and Usable Inkjet Printing - Infinite Possibilities Seen in Patents," published in February 2005 by Sumibe Techno Research (especially pages 115-133), as well as the methods described in Japanese Patent Publication Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325.

[0197] The composition layer formed by applying the composition may be dried (pre-baked). When pre-baking is performed, 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, for example, 50°C or higher, and also 80°C or higher. The pre-baking time is preferably 10 seconds to 3000 seconds, more preferably 40 to 2500 seconds, and even more preferably 80 to 220 seconds. Drying can be performed using a hot plate, oven, etc.

[0198] The method for manufacturing the film may further include a step of forming a pattern. Examples of pattern formation methods include a pattern formation method using photolithography and a pattern formation method using dry etching, with the pattern formation method using photolithography being preferred. However, if the film of the present invention is used as a flat film, the step of forming a pattern may not be necessary. The step of forming a pattern will be described in detail below.

[0199] (When forming patterns using photolithography) The photolithography method for forming a pattern preferably includes a step of exposing a composition layer formed by coating the composition of the present invention in a patterned manner (exposure step), and a step of developing and removing the unexposed parts of the composition layer to form a pattern (development step). If necessary, a step of baking the developed pattern (post-bake step) may be provided. Each step will be described below.

[0200] In the exposure process, the composition layer is exposed in a pattern. For example, the 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.

[0201] 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.

[0202] Furthermore, exposure may be performed by continuously irradiating with light, or by irradiating with light in pulses (pulsed exposure). Pulsed exposure is an exposure method that involves repeatedly irradiating and pausing with light in short cycles (for example, at the millisecond level or less).

[0203] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm². 2 Preferably, 0.05 to 1.0 J / cm² 2 This is more preferable. 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%). Furthermore, the exposure intensity can be appropriately set, usually 1000 W / m². 2 ~100,000 W / m 2 (For example, 5000W / m 2 , 15000W / m 2 , or 35000W / m 2 The oxygen concentration and exposure intensity can be combined as appropriate; for example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m². 2 At an oxygen concentration of 35% by volume, the illuminance is 20,000 W / m². 2 This can be done as follows.

[0204] Next, the unexposed portions of the composition layer after exposure are developed and removed to form a pattern. The development and removal of the unexposed portions of the composition layer can be done using a developer. This causes the unexposed portions of the composition layer in the exposure process to dissolve in the developer, leaving only the photocured portions on the support. 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.

[0205] Examples of developing solutions include organic solvents and alkaline developers, with alkaline developers being preferred. As the alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of alkaline agents include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxyamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, and 1,8-diazabicyclo[5.4.0]-7-undecene, as well as inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate. Alkaline agents with larger molecular weights are preferred from an environmental and safety perspective. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. The developer may also contain a surfactant. A nonionic surfactant is preferred as the surfactant. For convenience of transport and storage, the developer may be manufactured as a concentrated solution and then diluted to the required concentration at the time of use. The dilution ratio is not particularly limited, but can be set in the range of 1.5 to 100 times, for example. It is also preferable to wash (rinse) with pure water after development. It is preferable to supply the rinsing solution to the developed composition layer while rotating the support on which the developed composition layer has formed. It is also preferable to move the nozzle that discharges the rinsing solution from the center of the support to the periphery of the support. In this case, when moving the nozzle from the center to the periphery of the support, the speed of movement of the nozzle may be gradually reduced. By performing rinsing in this manner, in-plane variation of the rinse can be suppressed. Furthermore, a similar effect can be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the center to the periphery of the support.

[0206] After development and drying, it is preferable to perform additional exposure or heat treatment (post-bake). Additional exposure and post-bake are curing treatments after development to ensure complete hardening. The heating temperature in post-bake is preferably 100 to 240°C, and more preferably 200 to 240°C. Post-bake can be performed continuously or in batches using heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions. When performing additional exposure, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure may also be performed by the method described in Korean Published Patent No. 10-2017-0122130.

[0207] (When forming patterns using the dry etching method) Pattern formation by dry etching can be carried out by coating the above composition onto a support to form a composition layer, curing the composition layer to form a cured material layer, then forming a patterned photoresist layer on this cured material layer, and then dry etching the cured material layer using an etching gas with the patterned photoresist layer as a mask. Pre-baking is preferable when forming the photoresist layer. For pattern formation by dry etching, refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, which are incorporated herein by reference.

Next, the glass substrate on which the above film was deposited was irradiated with 250,000 lux of light using a xenon lamp for 100 hours, and the transmittance of the film after xenon lamp irradiation was measured. The change in transmittance (ΔT1) at each wavelength in the wavelength range of 700 to 1100 nm before and after xenon lamp irradiation was determined, and the light resistance was evaluated based on the largest value of ΔT1 across the entire measurement wavelength range according to the following criteria. A smaller value of ΔT1 indicates better light resistance. Transmittance change (ΔT1) = |Transmittance of the film before xenon lamp irradiation - Transmittance of the film after xenon lamp irradiation| A: ΔT1 is less than 3% B: ΔT1 is between 3% and 5%. C:ΔT1 is between 5% and less than 10% D:ΔT1 is 10% or more.

[0256] -Regarding the evaluation of heat resistance- The transmittance of the glass substrate on which the above film was deposited was measured in the wavelength range of 400 to 1100 nm using an ultraviolet-visible-near-infrared spectrophotometer (U-4100, manufactured by Hitachi High-Technologies Corporation). Next, the glass substrate on which the above film was deposited was heated at 200°C for 1 hour using a hot plate. The change in transmittance (ΔT2) at each wavelength in the wavelength range of 700 to 1100 nm before and after heating was determined, and the heat resistance was evaluated based on the largest value of ΔT2 across the entire measured wavelength range according to the following criteria. A smaller value of ΔT2 indicates better heat resistance. Transmittance change (ΔT2) = |Transmittance of the film before heating - Transmittance of the film after heating| A: ΔT2 is less than 3% B: ΔT2 is between 3% and 5%. C:ΔT2 is between 5% and less than 10% D:ΔT2 is 10% or more.
