ABSTRACT:
Aromatic diamines having a carboxylic acid group and various other diamines are reacted with aromatic tetracarboxylic dianhdyrides in organic polar solvents to provide polyimides. Polyimide compositions for electrodeposition which comprise the neutralized salts of the polyimides, water and poor solvents for the polyimides have good keeping quality and when electrodeposited on electrically conductive materials, can form polyimide coats that have high levels of appearance, smoothness and denseness while exhibiting good physical and chemical characteristics in such aspects as heat resistance, electrical insulation and chemical resistance.
