＜Evaluation of dispersion liquid＞ (coarse particles) On the glass substrate, the dispersion immediately after production and the dispersion stored at 45°C for 72 hours were applied using a spin coater so that the thickness after heating would be 0.25 μm, and heated at 85°C for 2 minutes using a hot plate. to form a film. This film was observed in 5 fields of view with an optical microscope (magnification: 200 times), the number of coarse particles with a maximum width of 0.3 μm or more was counted, and the coarse particles were evaluated according to the following evaluation criteria. The evaluation results when using the dispersion liquid immediately after production are described in the initial column, and the evaluation results when using the dispersion liquid stored at 45° C. for 72 hours are described in the elapsed time column. A: The number of coarse particles is 20 or less B: The number of coarse particles exceeds 20 and is less than 40 C: The number of coarse particles exceeds 40 and is less than 100 D: The number of coarse particles exceeds 100

(Stability over time) The viscosity (mPa·s) of each dispersion immediately after production was measured using an E-type viscometer (RE-85L manufactured by Toki Sangyo Co., Ltd.). After the measurement, each dispersion liquid was left to stand at 45° C. for 3 days, and then the viscosity was measured again. The viscosity change rate of the dispersion liquid before and after standing was calculated, and the stability over time was evaluated based on the following evaluation criteria. It can be said that the smaller the value of the viscosity change rate, the better the stability over time. The above viscosity measurements were all performed in a laboratory where the temperature and humidity were controlled at 22±5°C and 60±20%, and the temperature of the dispersion was adjusted to 25°C. All determinations were performed three times and the average value was used. Viscosity change rate (%) = (|Viscosity of the dispersion after standing at 45°C for 3 days - Viscosity of the dispersion immediately after production | / Viscosity of the dispersion immediately after production) × 100 A: The viscosity change rate is less than 5% B: The viscosity change rate exceeds 5% and is less than 10% C: The viscosity change rate exceeds 10% and is less than 15% D: The viscosity change rate exceeds 15%

＜Evaluation of development residue＞ On the glass substrate, a base layer forming composition (CT-4000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was applied using a spin coater so that the thickness after post-baking reached 0.1 μm, and a heating plate was used to heat the substrate at 220 The base layer was formed by heating at ℃ for 1 hour, and a glass substrate (support) with a base layer was obtained. Next, each resin composition was applied by spin coating so that the film thickness after post-baking would be 0.4 μm. Next, it was heated at 100° C. for 3 minutes using a hot plate. Next, the glass substrate was placed on the horizontal rotating stage of a spin/spray developing machine (model DW-30, manufactured by CHEMITRONICS CO., LTD.), and a developer (CD-2000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was used. (Manufacture) After spin-immersion development for 60 seconds at 23°C, the glass substrate was fixed on a horizontal rotating table using a vacuum suction cup. While rotating the glass substrate at 50 rpm using a rotating device, the glass substrate was rotated from above its rotation center. Pure water was supplied in a spray form from the discharge nozzle for rinsing, and then spray drying was performed. Furthermore, heat processing (post-baking) was performed for 5 minutes using a 200°C hot plate. The absorbance A1 of the glass substrate before coating the resin composition and the absorbance A1 of the glass substrate after post-baking were measured using a spectrophotometer, and the change in absorbance ΔA was calculated according to the following formula, and the maximum change in absorbance ΔA was used. The value of development residue was evaluated. In addition, the maximum value of the absorbance change amount ΔA refers to the absorbance change amount at the wavelength where the absorbance change amount ΔA becomes maximum. It means that the smaller the maximum value of the change in absorbance ΔA, the smaller the development residue. The change in absorbance ΔA=|Absorbance A1-Absorbance A2| A: The maximum value of the change in absorbance ΔA is 0.01 or less B: The maximum value of absorbance change ΔA exceeds 0.01 and is 0.03 or less C: The maximum value of absorbance change ΔA exceeds 0.03 and is 0.05 or less D: The maximum value of absorbance change ΔA exceeds 0.05
