[0004] [Patent Document 1] JP 2014-041341 A Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, a color filter has pixels of a plurality of colors. Such a color filter having pixels of a plurality of colors is manufactured by forming pixels of each color by sequentially forming a pattern of colored compositions for forming pixels of each color.

[0006] In recent years, color filters are sometimes formed on components with low heat resistance (for example, organic semiconductor elements such as organic electroluminescence display elements). Because such components have low heat resistance, it is desirable to form the pixels of the color filter in a low-temperature process at, for example, 150°C or less to prevent thermal damage to the support.

[0007] However, when pixels are formed by a low-temperature process, the degree of curing of the pixels may be insufficient, and when pixels of other colors are formed, color mixing with coloring compositions of other colors tends to occur, resulting in fluctuations in spectral characteristics.

[0008] Furthermore, according to the present inventors' investigations, it was found that even in the colored composition described in Patent Document 1, there is still room for further improvement in terms of color mixing with other colors.

[0009] Therefore, an object of the present invention is to provide a colored composition capable of forming a cured film in which mixing with other colors is suppressed. Another object of the present invention is to provide a cured film, a structure, a color filter, and a display device using the above-mentioned colored composition. [Means for solving the problem]

In this specification, the weight average molecular weight (Mw) and the number average molecular weight (Mn) are defined as values ​​calculated in terms of polystyrene measured by gel permeation chromatography (GPC).

[0013] <Coloring composition> The coloring composition of the present invention is a coloring composition comprising a colorant, a resin, a polymerizable compound, a photopolymerization initiator, and a compound having a cyclic ether group, The colorants include Color Index Pigment Green 7 and a yellow colorant; The coloring composition is characterized in that, when the absorbance of light having a wavelength of 450 nm is taken as 1, the wavelength at which the absorbance becomes 0.2 is in the wavelength range of 540 nm or more and 610 nm or less.

[0014] According to the coloring composition of the present invention, a cured film in which color mixing with other colors is suppressed can be formed. In particular, even when the cured film is formed at a low temperature of 150° C. or less (preferably 120° C. or less, more preferably 100° C. or less), a cured film in which color mixing with other colors is suppressed can be formed.

[0015] Although the detailed reason why such an effect is obtained is unclear, it is presumed that by using a coloring composition having the above-mentioned specific spectral characteristics and containing Color Index Pigment Green 7 and a yellow coloring agent as a coloring agent, the interaction between the pigments makes it easier to transmit heat, and when the coloring composition is heated and cured, the curing of the coloring composition proceeds quickly, and as a result, a cured film that is sufficiently cured can be formed even by heating at a relatively low temperature. Therefore, it is presumed that the coloring composition of the present invention can form a cured film in which mixing with other colors is suppressed.

[0016] In addition, by satisfying the above-mentioned specific absorbance characteristics, the coloring composition can form a cured film suitable for a green pixel having spectral characteristics excellent in color separation from other colors such as red and blue.

The green pixel preferably has the spectral characteristics described in the above-mentioned section on the cured film of the present invention. In addition, the red pixel and the blue pixel preferably have the spectral characteristics described in the above-mentioned section on the color filter.

[0289] <Pixel formation method> A method for forming pixels will now be described. By using the colored composition of the present invention, for example, green pixels can be formed.

[0290] The method for forming pixels preferably includes a step of forming a colored composition layer by applying a colored composition on a support, a step of exposing the colored composition layer in a pattern, and a step of developing the colored composition layer after exposure. In forming pixels, it is preferable to perform all steps at a temperature of 150°C or less. In the present invention, "perform all steps at a temperature of 150°C or less" means that all steps of forming pixels using a colored composition are performed at a temperature of 150°C or less. When a step of heating is further provided after developing the colored composition layer after exposure, this heating step is also performed at a temperature of 150°C or less. Each step will be described in detail below.

[0291] In the step of forming the coloring composition layer, the coloring composition is applied onto a support to form the coloring composition layer. Examples of the support include a glass substrate, a polycarbonate substrate, a polyester substrate, an aromatic polyamide substrate, a polyamideimide substrate, and a polyimide substrate. An organic light-emitting layer may be formed on these substrates. In addition, an undercoat layer may be provided on the substrate to improve adhesion with an upper layer, prevent diffusion of a substance, or flatten the surface. The undercoat layer may be formed, for example, using a composition obtained by removing a colorant from the above-mentioned coloring composition of the present invention. The surface contact angle of the undercoat layer is preferably 20 to 70° when measured with diiodomethane. In addition, it is preferably 30 to 80° when measured with water. If the surface contact angle of the undercoat layer is within the above range, the resin composition has good wettability. The surface contact angle of the undercoat layer can be adjusted, for example, by adding a surfactant.

[0292] The coloring composition can be applied by a known method. For example, a dropping method (drop casting), a slit coating method, a spray method, a roll coating method, a rotary coating method (spin coating), a casting coating method, a slit and spin method, a pre-wetting method (for example, a method described in JP-A-2009-145395), various printing methods such as ejection printing such as inkjet (for example, on-demand method, piezo method, thermal method), nozzle jet, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing method, a transfer method using a mold, and a nanoimprint method can be mentioned. The application method in inkjet is not particularly limited, and examples thereof include the method shown in "Expanding and Usable Inkjet - Infinite Possibilities Seen in Patents -, published in February 2005, Sumibe Techno Research" (particularly pages 115 to 133), and the methods described in JP 2003-262716 A, JP 2003-185831 A, JP 2003-261827 A, JP 2012-126830 A, JP 2006-169325 A, etc. In addition, for the application method of the coloring composition, the descriptions in WO 2017 / 030174 and WO 2017 / 018419 can be referred to, and the contents of these are incorporated herein.

[0293] The colored composition layer formed on the support may be dried (prebaked). When prebaking is performed, the prebaking temperature is preferably 80° C. or less, more preferably 70° C. or less, even more preferably 60° C. or less, and particularly preferably 50° C. or less. The lower limit may be, for example, 40° C. or more. The prebaking time is preferably 10 to 3600 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0294] Next, the coloring composition layer is exposed to light in a pattern (exposure step). For example, the coloring composition layer can be exposed to light in a pattern by using a stepper exposure machine or a scanner exposure machine through a mask having a predetermined mask pattern. This allows the exposed part to be cured.

[0295] Examples of radiation (light) that can be used for exposure include g-line and i-line. 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 line (wavelength 248 nm) and ArF line (wavelength 193 nm), with KrF line (wavelength 248 nm) being preferred. Long-wave light sources with wavelengths of 300 nm or more can also be used.

[0296] In addition, during exposure, light may be continuously irradiated or may be irradiated in pulses (pulse exposure). Pulse exposure is an exposure method in which light irradiation and pauses are repeated in a short cycle (for example, millisecond level or less). In the case of pulse exposure, the pulse width is preferably 100 nanoseconds (ns) or less, more preferably 50 nanoseconds or less, and even more preferably 30 nanoseconds or less. There is no particular limit to the lower limit of the pulse width, but it can be 1 femtosecond (fs) or more, and can also be 10 femtoseconds or more. The frequency is preferably 1 kHz or more, more preferably 2 kHz or more, and even more preferably 4 kHz or more. The upper limit of the frequency is preferably 50 kHz or less, more preferably 20 kHz or less, and even more preferably 10 kHz or less. The maximum instantaneous illuminance is 50,000,000 W / m 2 More preferably, it is 100,000,000 W / m 2 More preferably, it is 200,000,000 W / m or more. 2 It is more preferable that the upper limit of the maximum instantaneous illuminance is 1000000000 W / m 2 Preferably, it is less than 800,000,000 W / m 2 More preferably, it is 500,000,000 W / m or less. 2 It is more preferable that the pulse width is equal to or less than 1000 s. The pulse width refers to the time during which light is irradiated in a pulse period. The frequency refers to the number of pulse periods per second. The maximum instantaneous irradiance refers to the average irradiance during the time during which light is irradiated in a pulse period. The pulse period refers to a period in which light irradiation and pause in pulse exposure constitute one cycle.

[0297] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm 2 The lower limit is preferably 0.05 J / cm 2 More preferably, it is 0.2 J / cm or more. 2 More preferably, it is 0.5 J / cm or more. 2 More preferably, it is 0.8 J / cm or more.2 More preferably, it is 1.0 J / cm or more. 2 It is even more preferable that the upper limit is 2.0 J / cm or more. 2 More preferably, it is 1.5 J / cm or less. 2 The exposure illuminance can be appropriately set, for example, to 50 mW / cm or less. 2 ~10W / cm 2 The lower limit of the exposure illuminance is preferably 500 mW / cm 2 More preferably, it is 800 mW / cm or more. 2 More preferably, it is 1000 mW / cm or more. 2 It is even more preferable that the upper limit of the exposure illuminance is 10 W / cm or more. 2 It is preferable that the power consumption is less than 7 W / cm 2 More preferably, it is 5 W / cm or less. 2 It is even more preferable that:

[0298] The oxygen concentration during exposure can be appropriately selected. In addition to exposure in air, exposure can be performed in a low-oxygen atmosphere with an oxygen concentration of 19 volume% or less (e.g., 15 volume%, 5 volume%, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21 volume% (e.g., 22 volume%, 30 volume%, or 50 volume%). The oxygen concentration and exposure illuminance can be appropriately combined, for example, at an oxygen concentration of 10 volume% and an illuminance of 1 W / cm. 2 , oxygen concentration 35% by volume, illuminance 2W / cm 2 etc.

[0299] In addition, light with a wavelength of more than 350 nm and less than 380 nm (preferably i-line) is irradiated at 1 J / cm 2 It is also preferable to expose the colored composition layer by irradiation with the above-mentioned exposure amount. By exposing the colored composition layer in this manner, it is possible to sufficiently cure the colored composition layer, and it is possible to produce pixels having excellent properties such as solvent resistance.

[0300] Next, the colored composition layer after exposure is developed. That is, the unexposed portion of the colored composition layer is developed and removed to form a pattern (pixel). The unexposed portion of the colored composition layer can be developed and removed using a developer. As a result, the colored composition layer in the unexposed portion in the exposure step is dissolved into the developer, and only the photocured portion remains. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, in order to improve the removability of residues, the process of shaking off the developer every 60 seconds and supplying new developer may be repeated several times.

[0301] Examples of the developer include organic solvents and alkaline developers, and alkaline developers are preferred. As the alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of the alkaline agent include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxylamine, 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, and inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium hydrogencarbonate, sodium silicate, and sodium metasilicate. As the alkaline agent, compounds with a large molecular weight are preferred in terms of the environment and safety. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. The developer may further contain a surfactant. Examples of the surfactant include the surfactants described above, and nonionic surfactants are preferred. The developer may be produced as a concentrated solution from the viewpoint of convenience of transportation and storage, and then diluted to a required concentration when used. The dilution ratio is not particularly limited, but can be set in the range of, for example, 1.5 to 100 times. It is also preferred to wash (rinse) with pure water after development. It is also preferred to rinse by supplying a rinsing liquid to the colored composition layer after development while rotating the support on which the colored composition layer after development has been formed. It is also preferred to perform the rinsing by moving the nozzle for ejecting the rinsing liquid from the center of the support to the periphery of the support. In this case, the nozzle may be moved while gradually decreasing the moving speed when moving the nozzle from the center of the support to the periphery. By performing the rinsing in this manner, the in-plane variation of the rinsing can be suppressed. The same effect can also be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the center to the periphery of the support.

[0302] After development and drying, it is also preferable to carry out additional exposure treatment or heat treatment (post-baking). Additional exposure treatment and post-baking are hardening treatments after development to complete hardening.

[0303] When post-baking is performed, the heating temperature is preferably 150°C or less. The upper limit of the heating temperature is more preferably 120°C or less, and even more preferably 100°C or less. The lower limit of the heating temperature is not particularly limited as long as it can promote the curing of the composition, but is more preferably 50°C or more, and even more preferably 75°C or more. 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 limit to the upper limit, but from the viewpoint of productivity, 20 minutes or less is preferable. It is also preferable to perform post-baking under an inert gas atmosphere. According to this embodiment, thermal polymerization can be progressed with very high efficiency without being inhibited by oxygen, and even when pixels are manufactured at a temperature of 120°C or less throughout the entire process, pixels having good flatness and excellent properties such as solvent resistance can be manufactured. Examples of inert gases include nitrogen gas, argon gas, helium gas, etc., and nitrogen gas is preferable. The oxygen concentration during post-baking is preferably 100 ppm or less.

[0304] When performing additional exposure treatment, it is preferable to expose by irradiating light having a wavelength of 254 to 350 nm. In a more preferred embodiment, the step of patternwise exposing the coloring composition layer (exposure before development) is performed by irradiating the coloring composition layer with light having a wavelength of more than 350 nm and not more than 380 nm (preferably light having a wavelength of 355 to 370 nm, more preferably i-line), and the additional exposure treatment (exposure after development) is preferably performed by irradiating the coloring composition layer after development with light having a wavelength of 254 to 350 nm (preferably light having a wavelength of 254 nm). According to this embodiment, the coloring composition layer can be appropriately cured by the first exposure (exposure before development), and the entire coloring composition layer can be almost completely cured by the next exposure (exposure after development). As a result, even under low temperature conditions, the coloring composition layer can be sufficiently cured to form pixels having excellent properties such as solvent resistance, adhesion, and rectangularity. When exposure is performed in two stages like this, the coloring composition is used as a photopolymerization initiator, and the absorption coefficient at a wavelength of 365 nm in methanol is 1.0 × 10 3 Photopolymerization initiator A1 with a concentration of 1.0×10 at 365 nm in methanol and a concentration of 1.0×10 2 mL / gcm or less and an extinction coefficient at a wavelength of 254 nm of 1.0 x 10 3 It is preferable to use a photopolymerization initiator A2 containing the photopolymerization initiator A2 at a concentration of 1 mL / gcm or more.

[0305] Exposure after development can be carried out, for example, using an ultraviolet photoresist curing device, which may irradiate light having a wavelength of, for example, 254 to 350 nm as well as other light (for example, i-line).

[0306] Furthermore, the exposure source spectrum when performing additional exposure treatment is preferably a continuous spectrum, and from the viewpoint of improving solvent resistance and adhesion to the substrate, it is preferable that it has a spectral distribution different from that of the exposure before development, for example, the following radiations can be mentioned. Among them, (b) and (c) are preferred in that they can achieve a higher level of improvement in solvent resistance and adhesion to the substrate. Furthermore, when the (A) colorant contains a dye, the dye generally absorbs ultraviolet light or short-wavelength visible light and may be photodecomposed, so radiation (c) with fewer high-intensity components on the short-wavelength side is preferred. (a) Radiation having a different spectral distribution from that of the exposure light before development, and in which 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 spectral distribution from that of the exposure light before development, the peak intensity at a wavelength of 313 nm (j-line) being 1 / 3 or more of the peak intensity at a wavelength of 365 nm (i-line). There is no particular upper limit to the peak intensity at a wavelength of 313 nm, but it is preferably smaller than the peak intensity at a wavelength of 365 nm, and more preferably 3 / 4 or less. (c) Radiation having a different spectral distribution from that of the exposure light before development, including wavelengths of 405 nm (h-line) and 436 nm (g-line), with peak intensities at wavelengths of 313 nm (j-line) and 365 nm (i-line) being 1 / 4 or less, preferably 1 / 10 or less, and more preferably 1 / 20 of the smaller of the peak intensities at wavelengths of 405 nm (h-line) and 436 nm (g-line). Note that there is no particular lower limit for the peak intensities at wavelengths of 313 nm (j-line) and 365 nm (i-line). In this case, the exposure before development is preferably radiation having a wavelength of 365 nm (i-line), 405 nm (h-line), and 436 nm (g-line), and the peak intensity at a wavelength of 313 nm (j-line) is less than 1 / 6 of the peak intensity at a wavelength of 365 nm (i-line).

[0307] Radiation exhibiting such spectral characteristics can be obtained, for example, by using a light source exhibiting the above-mentioned spectral characteristics, or by passing radiation emitted from a high-pressure mercury lamp through an ultraviolet cut filter or a bandpass filter.

[0308] The exposure dose after development is 0.03 to 4.0 J / cm 2 is preferable, and 0.05 to 3.5 J / cm 2 The difference in wavelength between the light used for exposure before development and the light used for exposure after development is preferably 200 nm or less, and more preferably 100 to 150 nm.

[0310] The organic electroluminescence display device may have a light source made of a white organic electroluminescence element. The white organic electroluminescence element is preferably a tandem structure. The tandem structure of the organic electroluminescence element is described in JP 2003-045676 A, edited by Akiyoshi Mikami, "The Frontline of Organic EL Technology Development - High Brightness, High Precision, Long Life, Know-how Collection", Technical Information Association, pp. 326-328, 2008, etc. The spectrum of white light emitted by the organic EL element preferably has strong maximum emission peaks in the blue region (430 nm to 485 nm), green region (530 nm to 580 nm), and yellow region (580 nm to 620 nm). In addition to these emission peaks, it is more preferable that the organic EL element has a maximum emission peak in the red region (650 nm to 700 nm).

[0311] The organic electroluminescence display device may have a lens on the color filter. The lens may have various shapes derived by optical system design, such as a convex shape and a concave shape. For example, a concave shape (concave lens) can easily improve the light collecting property. The lens may be in direct contact with the color filter, or another layer such as an adhesion layer or a planarization layer may be provided between the lens and the color filter. The lens may be arranged and used in the manner described in International Publication No. WO 2018 / 135189.

[0312] <Solid-state imaging element> The colored composition and the cured film of the present invention can also be used for a solid-state imaging device. The configuration of the solid-state imaging device is not particularly limited as long as it has the cured film of the present invention and functions as a solid-state imaging device, and examples thereof include the following configurations.

[0313] The substrate has a plurality of photodiodes constituting a light receiving area of ​​a solid-state imaging device (such as a CCD (charge-coupled device) image sensor or a CMOS (complementary metal oxide semiconductor) image sensor) and a transfer electrode made of polysilicon or the like, a light shielding film having an opening only for the light receiving portion of the photodiode on the photodiode and the transfer electrode, a device protection film made of silicon nitride or the like formed on the light shielding film so as to cover the entire light shielding film and the light receiving portion of the photodiode, and a color filter on the device protection film. Furthermore, the device protection film may have a light collecting means (e.g., a microlens, etc., the same below) on the device protection film and below the color filter (on the side closer to the substrate), or a light collecting means on the color filter. The pixels of the color filter may be embedded in a space partitioned by partitions, for example, in a lattice shape. In this case, the refractive index of the partitions is preferably lower than the refraction of the pixels. Examples of imaging devices having such a structure include those described in JP 2012-227478 A, JP 2014-179577 A, WO 2018 / 043654 A, and U.S. Patent Application Publication No. 2018 / 0040656 A.
