Abstract
A conducting non-aqueous colloidal polyamic acid electrodeposition composition is made by reacting (1) 1 part polyamic acid and 29-37 parts non-aqueous, organic solvent for the acid with (2) 0.8-1.2 parts of a nitrogen containing base to form an organic salt which is added to 50-150 parts of a non-aqueous, organic non-electrolizable, non-solvent for the acid salt.
