Further, the exposure illuminance can be set appropriately, and is usually selected from the range of 1000W/m ² to 100000W/m ² (for example, 5000W/m ² , 15000W/m ² , or 35000W/m ² ). Can be done. The oxygen concentration and the exposure illuminance may be appropriately combined. For example, the illuminance may be 10,000 W/m ² when the oxygen concentration is 10% by volume, and 20,000 W/m ² when the oxygen concentration is 35% by volume.

Next, the unexposed portions of the colored composition layer are developed and removed to form a pattern (pixel).

The resulting dispersion was heated at a temperature of 45° C. for 7 days. The viscosity of the pigment dispersion before and after heating was measured, and the absolute value of the difference between the viscosity of the dispersion before and after heating was calculated. The viscosity of the dispersion liquid was measured using a viscometer (TV-22 viscometer, cone plate type, manufactured by Toki Sangyo Co., Ltd.). The viscosity of the dispersion liquid was measured by adjusting the temperature of the pigment dispersion liquid to 25°C. The rate of viscosity increase over time was calculated from the following formula, and the rate of viscosity increase over time was evaluated based on the following criteria. The evaluation results are listed in the "Thickening rate over time" column of the table.
Viscosity increase over time (%) = | Viscosity of dispersion before heating - Viscosity of dispersion after heating | / Viscosity of dispersion before heating × 100
A: The rate of increase in viscosity over time was less than 5%.
B: The rate of increase in viscosity over time was 5% or more and less than 15%.
C: The rate of increase in viscosity over time was 15% or more and less than 25%. D: The rate of increase in viscosity over time was 25% or more.

(evaluation)
<Evaluation of moisture resistance>
After applying CT-4000L solution (manufactured by Fujifilm Electronics Materials Co., Ltd.; transparent base agent) on a glass substrate so that the dry film thickness is 0.1 μm and drying it to form a transparent film, Heat treatment was performed at 220°C for 5 minutes. Next, each coloring composition was applied by spin coating so that the film thickness after prebaking was 0.6 μm. Then, using a hot plate, it was prebaked at 100°C for 2 minutes. Next, using an i-line stepper exposure device FPA-3000i5+ (manufactured by Canon Inc.), the film was exposed to light having a wavelength of 365 nm at an exposure dose of 500 mJ/cm ² to produce a film. Next, the glass substrate was placed on the horizontal rotary table of a spin shower developing machine (Model DW-30, manufactured by Chemitronics Co., Ltd.), and developed using a CD-2000 (manufactured by Fujifilm Electronics Materials Co., Ltd.). Paddle development was performed at 23° C. for 60 seconds, and the glass substrate was rotated at a rotation speed of 50 rpm using a rotating device. p. m. While rotating at revolutions per minute (revolutions per minute), pure water was supplied from above the center of rotation in the form of a shower from a jet nozzle to perform rinsing treatment, followed by post-baking at 200° C. for 3 minutes to produce a film. However, in Example 101, the above-mentioned exposure, development, and post-baking were omitted, and the film obtained after pre-baking was used as it was for the moisture resistance test. The obtained film was subjected to a humidity resistance test in which it was left to stand for 96 hours in an atmosphere of a temperature of 110° C. and a relative humidity of 85% using a constant temperature and humidity chamber (manufactured by Yamada Kagaku Co., Ltd., IW222).
For each film before and after the moisture resistance test, the transmittance in the wavelength range of 300 to 800 nm was measured using a spectrophotometer (UV3600, manufactured by Shimadzu Corporation, reference: glass substrate). Transmittance (%) - Transmittance of membrane after moisture resistance test (%)) / Transmittance of membrane before moisture resistance test (%)] × 100 | Calculate the rate of change in permeability expressed as (%) The moisture resistance was evaluated using the following criteria. The evaluation results are listed in the "Moisture resistance" column of the table.
A: The transmittance variation was less than 2% in the entire wavelength range of 300 to 800 nm.
B: The transmittance variation was less than 5% in the entire wavelength range of 300 to 800 nm, and the transmittance variation in at least some wavelengths was 2% or more and less than 5%.
C: The transmittance variation was less than 10% in the entire wavelength range of 300 to 800 nm, and the transmittance variation in at least some wavelengths was 5% or more and less than 10%.
D: The transmittance variation was 10% or more in at least a part of the wavelength range of 300 to 800 nm.

As shown in the table above, the colored compositions of Examples were able to form films with excellent moisture resistance. Films formed from the colored compositions of Examples can be suitably used for optical filters, solid-state imaging devices, and image display devices.
