Synthetic example 1

[0173] Synthesis Example 1. Synthesis of Alkali-Soluble Resin

[0174] In a 1000mL flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction tube, 120 parts by weight of propylene glycol monomethyl ether acetate, 80 parts by weight of propylene glycol monomethyl ether, 2 parts by weight of AIBN, Nitrogen substitution was carried out with 13 parts by weight of acrylic acid, 10 parts by weight of benzyl methacrylate, 57 parts by weight of styrene, 20 parts by weight of methyl methacrylate, and 3 parts by weight of n-dodecylmercaptan. Then, stirring was carried out to raise the temperature of the reaction liquid to 110° C., and after the temperature was raised, it was reacted for 6 hours.

[0175] The solid content acid value of the alkali-soluble resin produced in this way was 100.2 mgKOH / g, and the weight average molecular weight Mw measured by GPC was about 15110.

[0176]

Embodiment 1～6 and comparative example 1～2

[0178] The cyan photosensitive resin compositions of Examples 1-6 and Comparative Examples 1-2 were manufactured with the composition of following Table 1.

experiment example 1

[0189] Experimental example 1. Production of color filter and measurement of spectral transmittance

[0190] The cyan photosensitive resin compositions of Examples 1 to 6 and Comparative Examples 1 to 2 were each applied by spin coating on a 2-inch glass substrate (manufactured by Corning Incorporated, "EAGLE XG"), and placed on a hot plate. , maintained at a temperature of 100° C. for 3 minutes to form a thin film.

[0191] Then, a test photomask having a pattern with a stepwise change in transmittance in the range of 1 to 100% and an exposed portion pattern of 3×3 cm was placed on the above-mentioned film, and the distance between the test photomask and the test photomask was 100 μm, and ultraviolet rays were irradiated. . At this time, the ultraviolet light uses a 1kW high-pressure mercury lamp containing all g, h and i lines, at a rate of 100mJ / cm 2 illuminance without the use of special optical filters.

[0192] The film irradiated with the above-mentioned ultraviole...
