As used herein, "(meth)acrylate" refers to either or both of acrylate and methacrylate, "(meth)acrylic" refers to either or both of acrylic and methacrylic, and "(meth)acryloyl" refers to either or both of acryloyl and methacryloyl. In the structural formulae herein, Me refers to a methyl group, Et refers to an ethyl group, Bu refers to a butyl group, and Ph refers to a phenyl group. As used herein, infrared radiation refers to light (electromagnetic waves) with a wavelength of 700 to 2500 nm.

[0012] <Composition> The composition of the present invention is characterized by containing a coloring material containing a pigment, a compound represented by formula (1), a resin having an amine value, and a solvent.

[0013] The composition of the present invention has good dispersibility and storage stability, and can form a film with excellent moisture resistance. The reason for such effects is presumed to be as follows.

[0014] The compound represented by formula (1) has a dye skeleton, and is therefore presumed to interact with the pigment and adsorb to the surface of the pigment. Furthermore, the compound represented by formula (1) contains an acid group or a salt thereof, and is presumed to adsorb to the resin having an amine value through an acid-base reaction interaction. Therefore, it is presumed that a strong network structure is formed in the composition between the pigment, the compound represented by formula (1), and the resin having an amine value. It is presumed that the formation of such a network structure in the composition can suppress pigment aggregation and improve the dispersibility of the pigment. Furthermore, the compound represented by formula (1) has a structure in which R １ is a hydrocarbon group having 2 to 30 carbon atoms which may have a substituent, or a heteroaryl group which may have a substituent, so R １ It is presumed that the site of R acts as a steric hindrance, which can suppress bridging and aggregation between the compound represented by formula (1) and the resin, thereby suppressing an increase in viscosity over time and improving storage stability. Furthermore, in a high humidity environment, the compound having a dye skeleton in the film tends to easily form associations. When the compound having a dye skeleton forms associations, the spectral characteristics of the film may fluctuate. The compound represented by formula (1) used in the composition of the present invention is １ is the above group, so R １ It is presumed that the moiety acts as a steric hindrance, inhibiting the formation of the association of the compound represented by formula (1) in the film. Therefore, it is presumed that even when the film obtained using the composition of the present invention is exposed to a humid environment, the fluctuation of the spectroscopic properties of the film can be suppressed. Therefore, it is presumed that the use of the composition of the present invention can form a film with excellent moisture resistance.

[0339] <Method for Producing Film> The film of the present invention can be produced through a step of applying the composition of the present invention.

[0340] Examples of the support include those described above. As a method for applying the composition, a known method such as spin coating can be used. For example, the application method described in paragraph 0207 of WO 2022 / 085485 can be used.

When prebaking is performed, the prebaking 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, or can be 80°C or higher. The prebaking 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, an oven, or the like.

[0342] The film manufacturing method may further include a step of forming a pattern. Examples of the pattern forming method include a pattern forming method using a photolithography method and a pattern forming method using a dry etching method, and a pattern forming method using a photolithography method is preferred. Note that when the film of the present invention is used as a flat film, the step of forming a pattern does not need to be performed. The step of forming a pattern will be described in detail below.

[0343] (When forming a pattern by photolithography) The pattern formation method by photolithography preferably includes a step of patternwise exposing a composition layer formed by applying the composition of the present invention (exposure step), and a step of developing and removing the unexposed portions of the composition layer to form a pattern (development step). If necessary, a step of baking the developed pattern (post-baking step) may be provided. Each step will be described below.

[0344] In the exposure step, the composition layer is exposed to light in a pattern. For example, the composition layer can be exposed to light in a pattern by using a stepper exposure machine, a scanner exposure machine, or the like, through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.

[0345] 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 of 300 nm or more can also be used.

[0346] The exposure may be performed by continuous irradiation with light or by pulsed irradiation (pulse exposure), which is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less).

[0347] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm ２ is preferred, and 0.05 to 1.0 J / cm ２ The oxygen concentration during exposure can be appropriately selected. In addition to exposure in the atmosphere, exposure may be performed in a low-oxygen atmosphere with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). The exposure illuminance can be appropriately set, and is usually 1000 W / m ２ ~100000W / m ２ (For example, 5000 W / m ２ , 15000W / m ２ , or 35,000 W / m ２ The oxygen concentration and exposure illuminance may be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m ２ , oxygen concentration 35% by volume, illuminance 20,000 W / m ２ etc.

[0348] Next, the unexposed portions of the composition layer after exposure are developed and removed to form a pattern. The unexposed portions of the composition layer can be developed and removed using a developer. As a result, the unexposed portions of the composition layer in the exposure step are dissolved into the developer, and only the photocured portions remain 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. Furthermore, to improve residue removability, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.

[0350] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). The additional exposure treatment or post-baking is a post-development curing treatment to ensure complete curing. The heating temperature in post-baking is preferably, for example, 100 to 240°C, more preferably 200 to 240°C. Post-baking can be performed continuously or batchwise using a heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions for the developed film. When additional exposure treatment is performed, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure treatment may also be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

[0351] (When forming a pattern by a dry etching method) Pattern formation by a dry etching method can be performed by a method in which the composition of the present invention is applied to a support to form a composition layer, the composition layer is cured to form a cured layer, a patterned photoresist layer is then formed on the cured layer, and the patterned photoresist layer is then used as a mask to dry etch the cured layer using an etching gas. In forming the photoresist layer, it is preferable to perform a pre-bake treatment. For pattern formation by a dry etching method, the description in paragraphs 0010 to 0067 of JP 2013-064993 A can be referred to, and the contents of this specification are incorporated herein by reference.

The transmittance of the glass substrate on which the above film was formed was measured in the wavelength range of 400 to 2000 nm using an ultraviolet-visible-near-infrared spectrophotometer (U-4100, manufactured by Hitachi High-Tech Corporation). This film was placed in an incubator at 85° C. and 95% humidity for 6 months and stored therein, whereby a moisture resistance test was performed. Next, the transmittance of the film after the moisture resistance test was measured. For the film before and after the moisture resistance test, the change in transmittance (ΔT) in the wavelength range of 400 to 2000 nm was calculated using the following formula, and the moisture resistance was evaluated based on the value at the wavelength with the largest ΔT among all the measured wavelengths, according to the following criteria. The smaller the ΔT value, the better the moisture resistance. Change in transmittance (ΔT) = |Transmittance of film before humidity resistance test−Transmittance of film after humidity resistance test| A: ΔT≦5% B: 5%<ΔT≦10% C: 10%<ΔT≦20% D: 20%<ΔT
