Abstract 1. A METHOD OF COATING A METALLIC ELECTRICAL CONDUCTOR COMPRISING THE STEPS OF: (A) CONTINOUSLY PASSING POSITIVELY CHARGED ELECTRICAL CONDUCTOR NEAR A NEGATIVELY CHARGED ELECTRODE IN A BATH OF A CONDUCTING NON-AQUEOUS POLYAMIC ACID COLLOIDAL ELECTRODEPOSITION COMPOSITION COMPRISING ACID SALT ELECTRODEPOSITION COMPOSITION COMPRISING ACID SALT WITHIN A SOLVENT MIXTURE, SAID ACID SALT BEING THE REACTION PRODUCT OF A POLYAMIC ACID AND A BASIC ORGANIC NITROGEN CONTAINING COMPOUND, SAID COLLOIDAL ELECTRODEPOSITION COMPOSITION COMPRISING ABOUT 1 PART BY WEIGHT POLYAMIC ACID, ABOUT 0.8 TO 1.2 PARTS BY WEIGHT BASIC ORGANIC NITROGEN CONTAINING COMPOUND, ABOUT 29 TO ABOUT 37 PARTS BY WEIGHT NON-AQUEOUS, ORGANIC SOLVENT FOR THE ACID AND ABOUT 50 TO ABOUT 150 PARTS BY WEIGHT NON-AQOUES ORGANIC, NON-SOLVENT FOR THE SALT, WHEREIN THE CURRENT DENSITY BETWEEN THE CONDUCTOR AND NEGATIVE ELECTRODE IS SUFFICIENT TO ELECTRODEPOSIT A COATING ON THE CONDUCTOR, AND (B) CURING THE COATING TO FORM A POLYIMIDE FILM ON THE CONDUCTOR.
