Description

[Technical field]

[0001] The present invention relates to a photosensitive composition and its use. [Background technology]

[0002] In recent years, the demand for optical filters used in liquid crystal displays, smartphones, infrared sensors, etc. has increased due to the increased demand. Color filters, which are a type of optical filter, are produced, for example, through the following steps: a step of applying a photosensitive composition to a substrate such as glass and removing the organic solvent from the coating by drying (hereinafter referred to as the drying step); a step of irradiating the coating with ultraviolet light or the like through a photomask having a desired pattern shape to harden the coating (hereinafter referred to as the exposure step); a step of washing and removing the unexposed parts of the coating with a developer (hereinafter referred to as the development step); and a step of heating the film to sufficiently harden the film (hereinafter referred to as the post-baking step) to obtain a pattern of the first color. Then, the same operation is performed using photosensitive compositions of different colors to sequentially form patterns of the second and subsequent colors to produce a color filter.

[0003] In the above-mentioned development step, an alkaline developer is used to wash and remove the unexposed parts. During this process, there is a problem that the exposed parts are chipped or peeled off, causing defects in the pattern. In addition, when a coating film is exposed to an alkaline developer, there is a problem that the coating film discolors (hereinafter referred to as water stains). Therefore, there is a demand for a photosensitive composition that does not cause pattern defects and water stains in the development step. Furthermore, the drying step also causes uneven drying on the coating film, resulting in a non-uniform coating thickness. Furthermore, in recent years, from an environmental standpoint, there has been a demand to reduce the use of fluorine-based compounds in the components of photosensitive compositions used in the production of color filters.

[0004] For example, Patent Document 1 discloses a colored composition containing a polymerizable compound having an alkylene oxide structure as an approach to improving pattern chipping during development. Patent Document 2 discloses a colored photosensitive resin composition that does not cause development stains, the colored photosensitive resin composition containing a colorant, an alkali-soluble resin, a photopolymerizable compound, and a solvent, the alkali-soluble resin containing a monomer of a specific structure, having a molecular weight of 1,2000 to 17,000, and an acid value of 60 to 120 KOHmg / g, and the photopolymerization initiator containing an oxime ester fluorene derivative compound. Patent Document 3 discloses a resist composition containing a fluorine-based surfactant of a specific structure as a resist composition that can obtain a coating film that is less likely to cause water stains. Furthermore, Patent Document 4 discloses a photosensitive resin composition that is excellent in suppressing the occurrence of drying unevenness, and that contains an alkali-soluble resin having a specific structure, a polymerizable compound having a specific structure, a photopolymerization initiator, and a surfactant having a surface tension of 23.0 mN / m or less in a 0.5 mass % propylene glycol monomethyl ether acetate solution.

[Brief description of the drawings]

[0027] [Figure 1] FIG. 1 is a schematic cross-sectional view of an infrared sensor having an optical filter of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, the embodiment for carrying out the photosensitive composition of the present invention will be described in detail. Note that the present invention is not limited to the following embodiment, and can be modified within the scope of the problem that can be solved.

[0029] In this specification, unless otherwise specified, "(meth)acryloyl", "(meth)acryl", "(meth)acrylic acid", "(meth)acrylate", or "(meth)acrylamide" means "acryloyl and / or methacryloyl", "acrylic and / or methacrylic", "acrylic acid and / or methacrylic acid", "acrylate and / or methacrylate", or "acrylamide and / or methacrylamide", respectively. Also, "CI" stands for Color Index (CI; published by The Society of Dyers and Colourists). In this specification, a polymerizable unsaturated group is an ethylenically unsaturated double bond. In this specification, a monomer is a compound that forms a resin by polymerization. A monomer is in an unreacted state, and a monomer unit is in a partial structural state in which a monomer forms a polymer after polymerization. In this specification, for low molecular weight compounds whose molecular weight can be specified, the molecular weight is a calculated value or measured by ESI-MS (electrospray ionization mass spectrometry), and for compounds having a molecular weight distribution, the molecular weight is a polystyrene-equivalent weight average molecular weight measured by gel permeation chromatography using tetrahydrofuran as a solvent. In this specification, the boiling points of organic solvents are values ​​at 1013.25 hPa. In this specification, a numerical range expressed using "to" means a range that includes the numerical values ​​before and after "to" as the lower and upper limits.

[0030] <Photosensitive composition> A photosensitive composition according to one embodiment of the present invention is a photosensitive composition comprising an alkali-soluble resin (A), a polymerizable compound (B), a polymerization initiator (C), a leveling agent (D), and an organic solvent (E), The leveling agent (D) contains a copolymer (D1) having a monomer unit (d1) represented by the following general formula (1) and a monomer unit (d2) represented by the following general formula (2), The organic solvent (E) contains an organic solvent (E1) having a boiling point of 100°C or more and less than 150°C, and an organic solvent (E2) having a boiling point of 150°C or more and less than 230°C. General formula (1) [ka] In general formula (1), R1's are each independently an alkyl group having 1 to 6 carbon atoms, or a group represented by -OSi(R5)3 (wherein R5's are each independently an alkyl group having 1 to 3 carbon atoms). Each R2 is independently an alkyl group having 1 to 6 carbon atoms. R3 is an alkyl group having 1 to 6 carbon atoms. R4 is a hydrogen atom or a methyl group. L1 is a divalent organic group or a single bond. n is an integer from 1 to 70. General formula (2) [ka] (In general formula (2), R6 is a hydrogen atom or an alkyl group having 1 to 18 carbon atoms. R7 is a hydrogen atom or a methyl group. m is an integer from 1 to 4. o is an integer from 2 to 200.

[0031] The mechanism by which the photosensitive composition having the above-mentioned structure can solve the problems of the present invention is not clear, but is speculated as follows.

[0032] Organic solvents (E1) with a boiling point of 100°C or more and less than 150°C (hereinafter simply referred to as organic solvents (E1)) are easy to evaporate during the coating and drying process. Therefore, they do not remain in the film and are unlikely to affect adhesion. However, because they dry quickly, the film loses fluidity and drying unevenness is likely to occur. In addition, crater-like depressions are likely to occur on the surface of the film, and surface defects are likely to occur. On the other hand, organic solvents (E2) with a boiling point of 150°C or more and less than 230°C (hereinafter simply referred to as organic solvents (E2)) are difficult to evaporate during the coating and drying process and remain in the film for a long time. Therefore, even if the non-volatile content in the film increases during the drying process, the film has fluidity, giving time for the film to spread evenly, and drying unevenness is unlikely to occur. However, they remain in large amounts in the film, which is likely to deteriorate adhesion. Therefore, it is speculated that by using organic solvent (E1) and organic solvent (E2) in combination, it is possible to maintain the fluidity of the film from the coating to drying process, suppress drying unevenness, and form a film with excellent adhesion. And, the copolymer (D1) (hereinafter simply referred to as copolymer (D1)) having monomer unit (d1) represented by general formula (1) and monomer unit (d2) represented by general formula (2) is presumed to have a silicone chain in the side chain of the monomer unit (d1) represented by general formula (1), so that the hydrophobic silicone chain is easily oriented on the film surface, suppressing uneven drying and water stains. Also, the monomer unit (d2) represented by general formula (2) has an alkylene oxide chain, so that it is moderately compatible with the alkali-soluble resin (A), suppressing the occurrence of defects such as pinholes.

[0033] Components that are or can be included in the photosensitive composition of one embodiment will be described in detail below.

[0034] [Alkali-soluble resin (A)] The photosensitive composition of the present invention contains an alkali-soluble resin (A).

[0035] The alkali-soluble resin (A) is not particularly limited as long as it dissolves in the alkali developer described below, and any known resin can be used. Examples of the resin include (meth)acrylic resin, styrene resin, styrene / (meth)acrylic resin, epoxy resin, urethane resin, polycarbonate resin, polyester resin, polyether resin, polyimide resin, polyamideimide resin, and cyclic olefin resin.

[0036] The weight average molecular weight (Mw) of the alkali-soluble resin (A) is preferably from 3,000 to 50,000, and more preferably from 4,000 to 40,000.

[0037] The acid value of the alkali-soluble resin (A) is preferably from 30 to 200 mgKOH / g, more preferably from 40 to 180 mgKOH / g.

[0038] The alkali-soluble resin (A) can be used alone or in combination of two or more kinds.

[0041] The alkali-soluble resin (A1) has flexibility. Therefore, the rigid part formed by polymerization of the polymerizable compound (B) described later and the flexible part of the alkali-soluble resin (A1) are present in the film, and it is presumed that the external stress or internal stress can be effectively alleviated, and the adhesion is improved. In addition, because it is flexible, even if the non-volatile content concentration becomes high in the drying process, the film has fluidity and tends to spread uniformly. In addition, it is presumed that the copolymer (D1) is also easily oriented on the surface, and therefore uneven drying and water stains can be suppressed.

[0042] The alkali-soluble resin (A1) is not particularly limited, and any known resin can be used. For example, a monomer forming a monomer unit (a1) having a homopolymer glass transition temperature of 0° C. or lower, and a copolymer with any other copolymerizable monomer can be used.

[0043] The glass transition temperature (hereinafter, also referred to as Tg) may be a measured Tg obtained by actual measurement. Specifically, the measured Tg may be a value measured by differential scanning calorimetry (DSC). However, if measurement is difficult due to decomposition of the resin, etc., the calculated Tg obtained by the following formula is applied. 1 / Tg=W1 / Tg1+W2 / Tg2+······+W n / Tg n Here, the resins to be calculated are W1 to W n n types of monomer components up to W n is the weight fraction of the nth monomer, Tg n is the glass transition temperature (absolute temperature) of the homopolymer of the nth monomer. The glass transition temperature of the homopolymer of each monomer (hereinafter also referred to as homopolymer) is the value shown in "Polymer Handbook, Third edition, John Wiley & Sons, 1989" edited by Brandrup, J. Immergut, EH.

[0388] [Storage stabilizer (Q)] The photosensitive composition of the present invention may contain a storage stabilizer (Q), which stabilizes the viscosity of the photosensitive composition over time.

[0393] When the total amount of the specific metal elements in the photosensitive composition is within the above range, the composition has excellent dispersion stability even after storage over time. The content of the specific metal elements can be measured by inductively coupled plasma emission spectrometry (ICP).

[0394] [Water content] The photosensitive composition of the present invention preferably has a water content of 2.0% by mass or less.

[0395] A photosensitive composition having a water content within the above range has excellent dispersion stability and sensitivity even after storage over time. The water content can be measured by a known method such as the Karl Fischer method.

[0396] [Method of producing photosensitive composition] The photosensitive composition of the present invention can be prepared by mixing the above-mentioned components. In preparing the composition, the components may be mixed at once, or each component may be dissolved or dispersed in the polymerizable compound (B) or the organic solvent (E) and then mixed successively. When using a component with low solubility, such as a pigment (G), it is preferable to first carry out a dispersion treatment. For example, a dispersion is produced by adding a pigment (G), a dispersing resin (I), an organic solvent (E), etc., and carrying out a dispersion treatment. Then, an alkali-soluble resin (A), a polymerizable compound (B), a polymerization initiator (C), a leveling agent (D), etc. are blended and mixed with the dispersion to produce the dispersion. The timing of blending each material is arbitrary. The dispersion process can also be carried out multiple times.

[0397] Examples of dispersing machines for carrying out the dispersion treatment include a two-roll mill, a three-roll mill, a ball mill, a horizontal sand mill, a vertical sand mill, an annular bead mill, and an attritor.

[0398] The average dispersed particle size (secondary particle size) of the particles in the dispersion is preferably from 30 to 200 nm, more preferably from 40 to 200 nm.

[0399] The average dispersed particle size (secondary particle size) is measured, for example, using Nikkiso Microtrack UPA-EX150, which employs dynamic light scattering (FFT power spectrum method), with particle permeability set to absorption mode, particle shape set to non-spherical, and D50 particle size set to average size. The dilution solvent used for measurement is the organic solvent used for dispersion, and it is preferable to measure samples treated with ultrasonic waves immediately after sample preparation, as this tends to provide results with less variation.

[0400] The photosensitive composition is preferably subjected to removal of coarse particles of 5 μm or more, preferably coarse particles of 1 μm or more, more preferably coarse particles of 0.5 μm or more, and mixed dust by means of centrifugation, filtration with a sintered filter or membrane filter, etc. The photosensitive composition of the present invention preferably does not substantially contain particles of 0.5 μm or more, and more preferably does not contain particles of 0.3 μm or less.

[0401] <Membrane> The film of the present invention is formed by using the above-mentioned photosensitive composition. The film is preferably a patterned film, but can also be used as a flat film.

[0402] [Membrane manufacturing method] The method for producing the film is not particularly limited, and any known method can be used. For example, the film can be produced through a step of applying the photosensitive composition of the present invention onto a substrate and a step of drying the composition.

[0403] [Coating process] Examples of the substrate include substrates made of materials such as glass, resin, and silicone. The glass may be colorless and transparent, or colored glass such as blue glass may be used depending on the application. Examples of the resin include polyester-based resins such as polyester terephthalate, polyolefin-based resins such as polypropylene and polyethylene, polycarbonate resins, and epoxy resins. The thickness of the substrate is preferably 0.01 to 10 mm. An organic light-emitting layer may be formed on these substrates. Also, an imaging element such as a CCD or a CMOS may be formed on the substrate. Also, an undercoat layer may be provided on the substrate as necessary to improve adhesion with the upper layer, prevent diffusion of substances, and flatten the surface.

[0404] The coating method is not particularly limited, and any known method can be used, such as a dropping method, a slit coating method, a spray method, a roll coating method, a spin coating method, a casting coating method, an inkjet method, flexographic printing, screen printing, gravure printing, and offset printing.

[0405] The thickness of the membrane can be appropriately adjusted depending on the purpose, and is preferably 0.05 to 20.0 μm, more preferably 0.3 to 10.0 μm.

[0406] [Drying process] The method for drying the film applied to the substrate is not particularly limited, and any known method can be used. For example, reduced pressure drying using a vacuum drying device, heat drying using a hot plate, an IR oven, a convection oven, or the like, and a combination of these methods can be used.

[0407] The drying temperature and time can be appropriately adjusted. The drying temperature is preferably about 50 to 130° C., and the drying time is preferably about 5 seconds to 5 minutes.

[0408] Next, a pattern is formed. The method for forming the pattern includes photolithography and dry etching, and photolithography is preferable. When the film is used as a flat film, the step of forming a pattern is not necessary, and the entire surface is exposed to light.

[0409] The method for forming the pattern will now be described in detail.

[0410] When forming a pattern by photolithography, the photosensitive composition of the present invention is applied onto a substrate, and the layer formed by drying is exposed to light in a pattern through a mask (exposure process), and the unexposed parts are removed with an alkaline developer (development process), and the pattern is then heat-treated (post-bake process).

[0411] [Exposure process] In the exposure process, the layer formed by coating and drying is exposed to a specific pattern through a mask using an exposure device such as a stepper. This allows the exposed portion to be cured. Examples of active energy rays used for exposure include ultraviolet rays such as g-rays (wavelength 436 nm), h-rays (wavelength 405 nm), and i-rays (wavelength 365 nm). Light with a wavelength of 300 nm or less 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). When using light with a specific wavelength, an optical filter can also be used. In addition, the exposure may be performed by continuous irradiation with light, or by repeating irradiation and pause of light in a short cycle (for example, on the order of milliseconds or less) (pulse exposure). In addition, a plurality of active energy rays may be used in combination, or exposure may be performed in a plurality of steps.

[0412] [Development process] Next, an alkaline development process is carried out, whereby the unexposed portions of the layer are dissolved in an alkaline developer, and only the hardened portions remain, yielding a patterned film. Examples of the alkaline developer include aqueous solutions containing alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, aqueous ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene, etc. Two or more of these alkaline compounds can be used in combination. The alkaline developer may contain a surfactant and an organic solvent in addition to the alkaline compound and water. The concentration of the alkaline developer is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. The pH of the alkaline developer is preferably 11 to 13, more preferably 11.5 to 12.5. When used at an appropriate pH, it suppresses roughening and peeling of the pattern and improves the remaining film rate after development. Examples of the developing method include a dipping method, a spraying method, a puddle method, etc. The developing temperature is preferably 15 to 40° C. After the alkaline development, it is preferable to wash with pure water.

[0413] [Post-bake process] After development, a heat treatment (post-baking) is performed, which improves the resistance of the film. The temperature is preferably 80 to 300° C., more preferably 100 to 260° C. The time is preferably about 2 minutes to 2 hours. When a material with low heat resistance is used for the substrate, when a substrate having an organic electroluminescence element as the light-emitting layer is used, or from the viewpoint of the environment, the temperature is preferably 180° C. or less.

[0415] <Solid-state imaging element> The solid-state imaging device of the present invention has the above optical filter. The solid-state imaging device is not particularly limited as long as it includes the optical filter of the present invention and functions as a solid-state imaging device. For example, the following configurations can be mentioned.

[0416] The substrate has a plurality of photodiodes constituting a light receiving area of ​​a solid-state imaging device (CCD image sensor, CMOS image sensor, etc.) and a transfer electrode made of polysilicon or the like, a light shielding film with only the light receiving part of the photodiode open 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 part of the photodiode, and the optical filter (color filter) of the present invention on the device protection film.

The filter may have a structure in which a cured film forming each color pixel is embedded in a space partitioned by partitions, for example, in a lattice shape. In this case, the partitions preferably have a low refractive index with respect to each color pixel. An imaging device including a solid-state imaging element of the present invention can be used for various purposes, such as digital cameras, electronic devices with imaging functions (such as mobile phones and smartphones), vehicle-mounted cameras, and surveillance cameras.

[0417] <Image display device> The image display device of the present invention includes the above optical filter. Examples of the image display device include a liquid crystal display and an organic EL display. The form used for the image display device is not particularly limited as long as it functions as an image display device. For example, the configuration described in "Next Generation Liquid Crystal Display Technology" (by Tatsuo Uchida, published by Kogyo Chosakai Co., Ltd. in 1994) can be mentioned. The definition of image display devices and details of each image display device are described, for example, in "Electronic Display Devices" (written by Sasaki Akio, published by Kogyo Chosakai Co., Ltd. in 1990) and "Display Devices" (written by Ibuki Yoshiaki, published by Sangyo Tosho Co., Ltd. in 1989).

[0418] <Infrared sensor> The infrared sensor of the present invention has the above optical filter. The form of the infrared sensor used is not particularly limited as long as it is provided with the optical filter of the present invention and functions as an infrared sensor, and examples thereof include the following configurations.

[0419] A substrate has a plurality of photodiodes constituting a light receiving area of ​​a solid-state imaging element (CCD image sensor, CMOS image sensor, etc.) and a transfer electrode made of polysilicon or the like. A light shielding film with only the light receiving portion of the photodiodes open is provided on the photodiodes and the transfer electrodes. A device protection film is provided on this light shielding film, and the optical filter of the present invention is provided on this device protection film.

[0420] 1 is a schematic cross-sectional view showing an example of the configuration of an infrared sensor equipped with an optical filter of the present invention. The infrared sensor shown in FIG.

[0421] The imaging area provided on the solid-state imaging element 110 is configured by combining an infrared cut filter 111 and a color filter 112 .

[0422] The infrared cut filter 111 transmits light in the visible light region (for example, light with a wavelength of 400 to 700 nm) and blocks light in the infrared region (for example, light with a wavelength of 800 to 1,300 nm).

[0423] The color filter 112 is a color filter having pixels formed therein that transmit and absorb light of specific wavelengths in the visible light region, and for example, a color filter having red (R), green (G), and blue (B) pixels formed therein is used.

[0424] Between the infrared transmission filter 113 and the solid-state imaging element 110, a resin film 114 that is capable of transmitting light of a wavelength that has passed through the infrared transmission filter 113 is disposed.

[0425] The infrared transmission filter 113 is a filter that has a visible light blocking property and transmits infrared rays of a specific wavelength. The infrared transmission filter 113 preferably blocks light with a wavelength of 400 to 830 nm and transmits light with a wavelength of 900 to 1,300 nm, for example.

[0426] A microlens 115 is disposed on the incident light h side of the color filter 112 and the infrared transmission filter 113. A planarization film 116 is formed so as to cover the microlens 115.

[0427] In the embodiment shown in FIG. 1, the resin film 114 is disposed, but instead of the resin film 114, an infrared transmission filter 113 may be formed.

[0428] This infrared sensor can simultaneously capture image information, making it possible to perform motion sensing that recognizes the object whose movement is to be detected. In addition, this infrared sensor can obtain distance information, making it possible to capture images that include 3D information. Furthermore, this infrared sensor can also be used as a biometric authentication sensor.

[0429] In addition to the above applications, the photosensitive composition of the present invention can also be used to form transparent spacers, colored spacers, and the like. EXAMPLES

[0430] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to these examples. In addition, "parts" means "parts by mass" and "%" means "% by mass". In addition, in the present invention, the non-volatile content or non-volatile content concentration refers to the mass residue after standing in an oven at 110°C for 3 hours.

[0431] Before describing the examples, each measurement method will be described.

[0432] (Average molecular weight of resin) The number average molecular weight (Mn) and weight average molecular weight (Mw) of the resin were measured by gel permeation chromatography (GPC) equipped with an RI detector. The instrument used was an HLC-8220GPC (manufactured by Tosoh Corporation), with two separation columns connected in series, and both packings were "TSK-GEL SUPER HZM-N" connected in series. The oven temperature was 40°C, a tetrahydrofuran (THF) solution was used as the eluent, and the flow rate was 0.35 ml / min. The sample was dissolved in a solvent consisting of 1% by mass of the above eluent, and 20 microliters were injected. The molecular weight is a polystyrene equivalent value.

[0433] (Acid value of resin) 80 ml of acetone and 10 ml of water were added to 0.5 to 1 g of the resin solution, and the solution was stirred to dissolve uniformly. The solution was titrated with an automatic titrator ("COM-555" manufactured by Hiranuma Sangyo Co., Ltd.) using a 0.1 mol / L KOH aqueous solution as the titrant to measure the acid value (mgKOH / g). The acid value per unit of non-volatile content of the resin was calculated from the acid value of the resin solution and the concentration of the non-volatile content of the resin solution.

[0434] (Amine value of resin) The amine value of the resin is the total amine value (mgKOH / g) measured according to the method of ASTM D 2074 and converted into non-volatile content.

[0435] <Production of alkali-soluble resin (A)> (Solution of alkali-soluble resin (A1-1) having monomer unit (a1) with homopolymer glass transition temperature of 0° C. or lower) 262.0 parts of propylene glycol monomethyl ether acetate (hereinafter, PGMAc) was placed in a reaction vessel equipped with a thermometer, a cooling tube, a nitrogen gas inlet tube, and a stirrer in a separable 4-neck flask, and heated to 120°C while injecting nitrogen gas into the vessel. At the same temperature, a mixture of 49.7 parts of 2-ethylhexyl acrylate (2-EHA), 99.4 parts of glycidyl methacrylate (GMA), 6.6 parts of dicyclopentanyl methacrylate (DCPMA), 19.0 parts of t-butylperoxy-2-ethylhexanoate as a polymerization initiator, and PGMAc was added dropwise from the dropping tube over 2.5 hours. After the dropwise addition was completed, the mixture was stirred at 120°C for another 2 hours to obtain a precursor. The atmosphere in the flask was then replaced with air, and 50.4 parts of acrylic acid (AA) as a modified compound, 0.6 parts of triphenylphosphine as a catalyst, and 0.2 parts of methylhydroquinone were added, and the mixture was reacted at 110°C for 10 hours. This caused the epoxy group of GMA to react with the carboxyl group of AA, generating hydroxyl groups by cleavage of the epoxy group of GMA and simultaneously introducing polymerizable unsaturated groups (GMA+AA). Next, 21.3 parts of tetrahydrophthalic anhydride (THPA) was added as a modifying compound and reacted at 110°C for 4 hours. This caused a part of the hydroxyl groups of GMA+AA to react with THPA (GMA+AA+THPA). After that, PGMAc was added so that the non-volatile content was 30 mass%, and an alkali-soluble resin (A1-1) solution having a monomer unit (a1) with a homopolymer glass transition temperature of 0°C or less was prepared. The acid value was 38 mgKOH / g and the weight average molecular weight was 12,000. The blending amounts in Table 2 are expressed in mol%.

[0436] (Alkali-soluble resin (A1-2) to (A1-7) solutions) Alkali-soluble resins (A1-2) to (A1-7) were synthesized by varying the type and amount of monomer and the amount of polymerization initiator so as to obtain the constituent molar ratios and weight average molecular weights shown in Table 2, and PGMAc was added to adjust the non-volatile content to 30 mass%.

[0437] [Table 2]

[0438] GMA+AA+SHA in Table 2 represents a polymerizable unsaturated group-containing monomer unit (a2) obtained by reacting some of the hydroxyl groups of GMA+AA with succinic anhydride (SHA).

[0439] (Alkali-soluble resin (A2-1) solution) 162.0 parts of PGMAc was placed in a reaction vessel equipped with a separable 4-neck flask equipped with a thermometer, a cooling tube, a nitrogen gas inlet tube, and a stirrer, and the vessel was heated to 120°C while injecting nitrogen gas into the vessel.
