After cooling, the substrate on which the colored composition layer was formed was exposed to a quartz glass photomask at a distance of 100 μm, and the substrate was exposed to an exposure machine (TME-150RSK; Topcon Corporation) at 150 mJ / cm under atmospheric conditions. 2 The photomask was irradiated with light at an exposure dose of 100 μm (based on 365 nm). A photomask with a 100 μm line and space pattern was used. The colored composition layer after the light irradiation was developed by immersion in an aqueous developer containing 0.12% of a nonionic surfactant and 0.04% of potassium hydroxide at 24° C. for 60 seconds, washed with water, and then post-baked in an oven at 230° C. for 20 minutes to obtain a colored pattern.

Before and after irradiation, the spectrum was measured using a colorimeter (OSP-SP-200; manufactured by Olympus Corporation), and the xy chromaticity coordinates (x, y) and stimulus value Y in the CIE XYZ color system were measured using the characteristic function of the C light source. From the measured values, the color difference ΔEab* was calculated using the method described in JIS Z 8730:2009 (7. Calculation method of color difference), and the results are shown in Table 2. The smaller ΔEab* means the smaller the color change. The differences in x, y, and Y before and after the test are also shown in Table 2 as Δx, Δy, and ΔY, respectively.
