Synthetic example 1
[0153] A polyester solution (solid concentration: 30.0% by mass) was obtained by reacting 12.0 g of HBPDA, 10.2 g of HBPA, 0.95 g of THPA, and 0.22 g of BTEAC as a catalyst in 54.48 g of PGMEA at 120° C. for 19 hours (P1). Mn of the obtained polyester was 2,280, and Mw was 4,200.
Synthetic example 2
[0155] A polyester solution (solid concentration: 30.0% by mass) was obtained by reacting 18.0 g of HBPDA, 4.54 g of BPDA, 15.9 g of HBPA, 2.01 g of THPA, and 0.19 g of BTEAC as a catalyst in 95.1 g of PGMEA at 120° C. for 19 hours (P2). Mn of the obtained polyester was 1,510, and Mw was 3,570.
