Zusammenfassung: | An electrodeposition liquid containing a polyamide-imide resin, a polar solvent, water, a poor solvent, and a base, wherein the polar solvent is an organic solvent having a boiling point exceeding 100deg c, and satisfying the relationship D(S-P) < 6 where D(S-P) is represented by formula (1), and the polyamide-imide has a weight average molecular weight of 10 * 104 to 30 * 104 or a number averagemolecular weight of 2 * 104 to 5 * 104. D(S-P) = [(dDS - dDP)2 + (dPS - dPP)2 + (dHS - dHP)2]1/2 (1).
本发明提供种电沉积液,其包含聚酰胺酰亚胺树脂、极性溶剂、水、不良溶剂及碱,其中,极性溶剂为沸点超过100℃且下述式(1)所表示的D满足D<6的关系的有机溶剂,聚酰胺酰亚胺的重均分子量为10×10~30×10或者聚酰胺酰亚胺的数均分子量为2×10~5×10。D=[(dD-dD)+(dP-dP)+(dH-dH)](1)。 |
