experiment example
[0193] Examples 1-4 and Comparative Examples 1-3 were produced by the ratio shown in following Table 1. The feeding unit of each composition is gram (g).
[0194] [Table 1]
[0195] [Table 1]
[0196]
[0197] Production of the substrate
[0198] The produced photosensitive resin composition was spin-coated (spincoated) on glass (5x5 cm), and it prebaked at 110 degreeC for 70 second, and formed a film. The distance between the substrate on which the film was formed and the photomask (photo mask) was set to 300 μm, and the entire surface of the substrate was irradiated with 30 mJ / cm using an exposure machine. 2 exposure.
[0199] Next, the exposed substrate was developed for 55 seconds with a developing solution (KOH, 0.04%), and post-baked at 230° C. for 20 minutes to prepare a substrate.
experiment example 1
[0200] Experimental example 1. Measurement of brightness
[0201] The color characteristics of the prepared substrates were confirmed using a spectrophotometer, and the luminance values are shown in the following [Table 2].
experiment example 2
[0202] Experimental example 2. Measurement of heat resistance
[0203] For the above prepared substrate, the color characteristics were confirmed using a spectrophotometer, and after further heat treatment for 1 hour in a convection oven (convection oven) at 230°C, the color characteristics were confirmed again, and the ΔEab value was obtained and shown in the following [Table 2 ].
[0204] [Table 2]
[0205] [Table 2]
[0206]
[0207] As shown in the above Table 2, it can be seen that when the photosensitive resin composition of Examples 1 to 4 containing both the compound represented by the above Chemical Formula 1 and the antioxidant is used to manufacture a color filter, the brightness and heat resistance characteristics are improved. Effect.
