Examples of optical filters include color filters, infrared transmission filters, and infrared cut filters. Since the compound represented by formula (1) has excellent visible transparency and infrared shielding properties, the composition of the present invention is particularly preferably used as a composition for an infrared cut filter.

[0218] <Method for Producing Film> The film of the present invention can be produced through a step of applying the composition of the present invention.

[0219] 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 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.

[0221] 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.

[0222] (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.

[0223] 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.

[0224] 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.

[0225] 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 (e.g., milliseconds or less).

[0226] 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.

[0227] 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.
