Abstract
Description
[Technical field]
[0001] The present invention relates to a photosensitive composition used to form an optical filter for use in a solid-state imaging device, an image display device, or the like. [Background technology]
[0002] The demand for optical filters used in liquid crystal display devices, digital cameras, smartphones, infrared sensors, etc. is growing due to the widespread use of these devices. In order to make these devices light, thin, and energy-efficient, organic EL (Electro-Luminescence) display devices using OLEDs (Organic Light Emitting Diodes) and other devices that do not require backlighting, and the use of organic materials for the photoelectron conversion film in image sensors, are being considered.
[0003] Since the heat resistance of an organic light-emitting layer used in an organic EL display device or the like is generally low, it is preferable that the photosensitive composition for forming an optical filter used in an organic EL display device is heated at a low temperature, for example, at 150° C. or less. As an investigation into the production of an optical filter at a low temperature, for example, Patent Document 1 discloses a colored photosensitive composition containing a colorant, a polymerizable compound, and a photopolymerization initiator, in which the absorbance of a solution obtained by dissolving the photopolymerization initiator in acetonitrile at 0.001% by mass at a wavelength of 340 nm is 0.45 or more. Patent Document 2 discloses a photosensitive resin composition containing an alkali-soluble resin, a polymerizable compound, a fluorene structure-containing oxime ester photopolymerization initiator, and a solvent. Patent Document 3 discloses a photosensitive colored resin composition containing a colorant, a (meth)acrylate copolymer-based dispersant, an alkali-soluble resin, a photopolymerizable compound, an oxime ester photopolymerization initiator having a specific structure, and a solvent. Patent Document 4 discloses a coloring composition that contains a red colorant, a resin having a repeating unit containing a blocked isocyanate group, a polymerizable compound, and a photopolymerization initiator as a coloring composition that can form a cured film in which mixing with other colors is suppressed even when an image is formed by a low-temperature process. Patent Document 5 discloses a photosensitive resin composition that contains a resin having a constitutional unit having an α,β-unsaturated carbonyl group, a constitutional unit having an active methylene group or an active methine group, and a constitutional unit having an acid group as a curable resin composition that can form a cured film with excellent solvent resistance and adhesion even when the temperature of the post-bake process is 200° C. or less.
[0004] Furthermore, the quality of an optical filter is significantly reduced if there are foreign matters, defects, or differences in thickness. Therefore, it is necessary to suppress the deterioration of the quality of the photosensitive composition used in the manufacture of an optical filter as much as possible between immediately after the manufacture of the photosensitive composition and when the composition is stored and used in the manufacture of an optical filter. For example, Patent Document 6 discloses a radiation-sensitive resin composition having excellent stability of sensitivity over time, which contains an oxime ester compound having at least one type of group selected from a branched alkyl group and a cyclic alkyl group, and has a water content of 0.1 to 2 mass% relative to the mass of the radiation-sensitive resin composition.

[0010] [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
[0011] 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.
[0012] In this specification, unless otherwise specified, "(meth)acryloyl", "(meth)acrylic", "(meth)acrylic acid", "(meth)acrylate", or "(meth)acrylamide" respectively means "acryloyl and / or methacryloyl", "acrylic and / or methacrylic", "acrylic acid and / or methacrylic acid", "acrylate and / or methacrylate", or "acrylamide and / or methacrylamide". In addition, "CI" means Color Index (CI; published by The Society of Dyers and Colourists). The polymerizable unsaturated group is an ethylenically unsaturated double bond. Regarding the molecular weight of the compound in the present invention, for low molecular weight compounds whose molecular weight can be specified, the molecular weight is a calculated value (formula weight) or a molecular weight 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. A monomer is a compound that will polymerize to form a resin. A monomer is in an unreacted state, and a monomer unit is a monomer that will polymerize to form a resin. Low temperature refers to temperatures below 150°C.
[0013] <Photosensitive composition> A photosensitive composition according to one embodiment of the present invention is a photosensitive composition comprising a pigment (A), an alkali-soluble resin (B), a polymerizable compound (C), a polymerization initiator (D), and an organic solvent (E), the alkali-soluble resin (B) contains an alkali-soluble resin (B1) having a thermally crosslinkable group-containing monomer unit (b1), the polymerization initiator (D) comprises a bisoxime ester polymerization initiator (D1); In the organic solvent (E) 100% by mass, the hydrogen bond term of the Hansen solubility parameter is 10 MPa 1 / 2 The composition is characterized in that it contains 0.1 to 20 mass % of the organic solvent (E1) described above.
[0014] The mechanism by which the photosensitive composition having the above-mentioned configuration can solve the problems of the present invention is not clear, but is speculated as follows.
[0015] When the alkali-soluble resin (B) contains an alkali-soluble resin (B1) having a thermocrosslinkable group-containing monomer unit (b1), a crosslinking reaction occurs by heating, improving the resistance of the film. When a bisoxime ester polymerization initiator (D1) is used in combination as the polymerization initiator (D), it has two radical generating groups in the molecule, so radicals can be generated efficiently, and it is presumed that the photoreaction is likely to proceed and the film resistance can be maintained at the same level as when heated at a high temperature, even when heated at a low temperature. On the other hand, a photosensitive composition containing both an alkali-soluble resin (B1) having a thermocrosslinkable group-containing monomer unit (b1) and a bisoxime ester polymerization initiator (D1) is likely to undergo a reaction during storage, and the quality after storage decreases. However, when the hydrogen bond term of the Hansen solubility parameter is 10 MPa in an organic solvent (E), the photosensitive composition is more likely to undergo a reaction during storage, and the quality after storage decreases. 1 / 2 It is presumed that when the organic solvent (E1) is contained in a specific amount as described above, it acts on each component contained in the photosensitive composition and suppresses reactions during storage, thereby improving the quality after storage.

[0368] A photosensitive composition in which the total amount of the specific metal elements is within the above range has excellent dispersion stability and sensitivity even after storage over time. The content of the specific metal elements can be measured by inductively coupled plasma emission spectrometry (ICP).
[0369] [Water content] The photosensitive composition of the present invention preferably has a water content of 2.0% by mass or less.
[0370] 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.
[0371] [Method of producing photosensitive composition] The photosensitive composition of the present invention can be prepared by mixing the above-mentioned components. When preparing the photosensitive composition, the components may be mixed at once, or each component may be dissolved or dispersed in the polymerizable compound (C) or the organic solvent (E) and then mixed successively. For example, a dispersion is produced by adding a pigment (A), a dispersing resin (K), an organic solvent (E), etc., and carrying out a dispersion treatment. Then, an alkali-soluble resin (B), a polymerizable compound (C), a polymerization initiator (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.
[0372] 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.
[0373] 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. If the particles have an appropriate particle size, a photosensitive composition having high dispersion stability is easily obtained.
[0374] 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 give results with less variation.
[0375] 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.
[0376] The photosensitive composition of the present invention is preferably used for forming a pattern by a photolithography method, although the present invention is not limited thereto.
[0377] <Membrane> The film of the present invention is a film formed from the above-mentioned photosensitive composition. The film is preferably a patterned film, but may also be used as a flat film without forming a pattern.
[0378] [Membrane manufacturing method] The method for producing the film is not particularly limited, and known methods can be used. In the present invention, the heating temperature throughout the entire process of film production is preferably 150°C or less, more preferably 130°C or less. By heating at 150°C or less, the performance of an organic EL element can be maintained when an image display device uses an organic EL element as a light source, an image sensor uses an organic photoelectric conversion film, or a heat-sensitive base material such as a plastic film is used. The heating temperature is preferably 50°C or more.
[0379] In the production of the film, first, the photosensitive composition is applied onto a substrate. Examples of the substrate include glass, resin, silicon, and the like. The glass is preferably colorless and transparent. Depending on the application, colored glass such as blue glass may be used. The substrate may have an organic light-emitting layer. The substrate may also have an imaging element such as a CCD or CMOS. If necessary, an undercoat layer may be provided on the substrate to improve adhesion with the upper layer, prevent diffusion of substances, and flatten the surface.
[0380] The coating method may be a known method, 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, or offset printing.
[0381] 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.
[0382] Next, a pattern is formed. Examples of a method for forming a pattern include a photolithography method and a dry etching method. Among these, a photolithography method is preferable. When the film is used as a flat film, the step of forming a pattern is not necessary, and after coating, the film is dried or the entire surface is exposed to light as necessary.
[0383] A method for forming a pattern by photolithography will be described in detail below. In the photolithography method, a layer formed by coating the photosensitive composition of the present invention on a substrate is dried at a temperature of 150°C or less as necessary, and then exposed to light in a pattern through a mask (exposure step), and the unexposed parts are removed by alkaline development (development step), and the pattern is then heat-treated (heating step).
[0384] [Exposure process] In the exposure step, the layer formed by coating 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).

[0404] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to these examples. Note that "parts" means "parts by mass" and "%" means "% by mass". 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.
[0405] Before describing the examples, each measurement method will be described.
[0406] The weight average molecular weight (Mw), number average molecular weight (Mn), acid value (mgKOH / g), amine value (mgKOH / g), and extinction coefficient (L / mol cm) of the resin are measured as follows.
[0407] (Molecular weight) Number average molecular weight (Mn) and weight average molecular weight (Mw) 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.
[0408] (Acid value) 80 ml of acetone and 10 ml of water were added to 0.5 to 1 g of sample 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, and the acid value (mgKOH / g) was measured. The acid value per unit of nonvolatile content was calculated from the acid value of the solution and the concentration of nonvolatile content in the solution.
[0409] (amine value) The amine value is the total amine value (mgKOH / g) measured according to the method of ASTM D 2074 and converted into non-volatile content.
[0410] (Extinction coefficient) 0.001 g of polymerization initiator was dissolved in 0.01 L of propylene glycol monomethyl ether acetate to prepare a 0.1 mass% measurement solution. The 0.1 mass% measurement solution was then diluted with propylene glycol monomethyl ether acetate to prepare 0.01 mass% and 0.001 mass% measurement solutions. The absorbance of each concentration of the measurement solution was measured at a wavelength of 365 nm using a spectrophotometer (Hitachi High-Technologies Corporation, "U-3010"), and the extinction coefficient (L / mol cm) was calculated from the slope when the horizontal axis was the molar concentration and the vertical axis was the absorbance.
