Embodiment 1
[0197] BODA (1.30 g, 5.2 mmol), 3AMPDA (0.63 g, 2.6 mmol), DA-1 (2.20 g, 5.2 mmol), and DA-2 (1.98 g, 5.2 mmol) were dissolved in NMP (22.8 g), After making it react at 60 degreeC for 5 hours, CBDA (1.50g, 7.7mmol) and NMP (7.6g) were added, it was made to react at 40 degreeC for 10 hours, and the polyamic-acid solution was obtained.
[0198] After adding NMP to this polyamic-acid solution (34g) and diluting to 6.5 mass %, acetic anhydride (5.9g) and pyridine (1.8g) were added as an imidization catalyst, and it was made to react at 70 degreeC for 3 hours. This reaction solution was poured into methanol (500 ml), and the obtained precipitate was filtered off. This deposit was wash|cleaned with methanol, it dried under reduced pressure at 100 degreeC, and the polyimide powder (A) was obtained. The imidization rate of this polyimide was 76%, the number average molecular weight was 13000, and the weight average molecular weight was 48000.
[0199] NMP (22.0g) was added to the ob...
Embodiment 2
[0219] Glycidyl methacrylate (GMA) (7.11 g, 50.0 mmol) and methyl methacrylate (MMA) (5.01 g, 50.0 mmol) were dissolved in NMP (116.4 g), and degassed with a diaphragm pump for 5 minutes, Then, azobisisobutyronitrile (AIBN) (0.82 g, 5.0 mmol) was added, and deaeration was performed again for 5 minutes. Then, it was made to react at 60 degreeC for 30 hours, and the 1:1 copolymer of GMA and MMA was obtained. Butyl cellosolve (BCS) (86.2g) was added to this polymer solution, and the polymethacrylate solution (C) of 6 mass % was obtained. The polymer had a number average molecular weight of 6800 and a weight average molecular weight of 10800.
[0220] DA-1 (42.3 mg, 0.1 mmol) was added and melt|dissolved to this solution (C) (10.0g), and the polymethacrylate solution (C1) was obtained.
[0221] "Confirmation of the ability of light to generate bases"
[0222] The polymethacrylate solution (C1) obtained above was spin-coated on the ITO surface of the ITO electrode substrate, and...
