[0151] Hereinafter, although an Example is given and this invention is demonstrated, this invention is not limited to these examples. First, the evaluation method in each Example and a comparative example is demonstrated. In the evaluation of the photosensitive resin composition (hereinafter referred to as varnish), a varnish previously filtered with a 1 μm polytetrafluoroethylene filter (manufactured by Sumitomo Electric Industries, Ltd.) was used.
[0152] (1) Determination of content of (C) compound in photosensitive resin composition (varnish)
[0153] 0.03 g of the component (A) polymerized under the conditions of using the compound (C) and 0.01 g of methyl 3-nitrobenzoate as an internal standard substance were dissolved in 0.7 g of deuterated dimethyl sulfoxide, and used Analysis was performed by NMR (manufactured by JEOL Ltd., GX-270). Based on the peak area around 3.9 ppm derived from methyl 3-nitrobenzoate, the amount of the (C) compound contained in the (A) compone...

[0174] [Synthesis Example 1] Synthesis of diamine compound (HA)
[0175] Dissolve 164.8 g (0.45 moles) of 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane (hereinafter referred to as BAHF) in 900 mL of acetone and 156.8 g (2.7 moles) of propylene oxide, and cool to -15°C. A solution obtained by dissolving 183.7 g (0.99 mol) of 3-nitrobenzoyl chloride in 900 mL of acetone was added dropwise thereto. After completion of the dropwise addition, the reaction was carried out at -15°C for 4 hours, and then returned to room temperature. The precipitated white solid was filtered and vacuum-dried at 50°C.
[0176] 270 g of the solid was put into a 3 L stainless steel autoclave, and dispersed in 2400 mL of methyl cellosolve, and 5 g of 5% palladium-carbon was added. Hydrogen was introduced thereinto with a balloon, and the reduction reaction was carried out at room temperature. After 2 hours, confirm that the balloon is no longer deflated, and end the reaction. After completion of...

[0179] [Synthesis example 2] Synthesis of polyimide resin (A-1)
[0180] Dissolve 62.04 g (0.2 mol) of bis(3,4-dicarboxyphenyl) ether dianhydride (hereinafter referred to as ODPA) in 1,000 g of N-methyl-2-pyrrolidone (hereinafter referred to as NMP) under dry nitrogen gas middle. Add 58.60 g (0.16 mol) of BAHF, 12.00 g (0.02 mol) of ED-600 (trade name, manufactured by HUNTSMAN Co., Ltd.), and 4.37 g (0.04 mol) of 3-aminophenol as a capping material to this together with 250 g of NMP , react at 60°C for 1 hour, then react at 160°C for 6 hours. After the reaction, the solution was cooled to room temperature, and then the solution was poured into 10 L of water to obtain a white precipitate. This precipitate was collected by filtration, washed with water three times, and then dried for 40 hours with an 80° C. vacuum dryer to obtain a polyimide resin (A-1).
