Method of maintaining bath composition in continuous electrodeposition process

Claim 1

IN A COATING PROCESS WHICH COMPRISES IMMERSING A SERIES OF ELECTRICALLY CONDUCTIVE OBJECTS IN A LIQUID COATING BATH HAVING AN ORGANIC COATING MATERIAL DISPERSED THEREIN AND A FIRST ELECTRODE IN ELECTRICAL COMMUNICATION THEREWITH AND SPACED APART FROM SAID OBJECTS, PROVIDING A DIRECT CURRENT FLOW OF ELECTRICAL ENERGY THROUGH SAID BATH AND BETWEEN SAID FIRST ELECTRODE AND AN OBJECT OF SAID SERIES IMMERSED IN SAID BATH THEREBY ELECTRICALLY INDUCING DEPOSITION OF SAID COATING MATERIAL UPON SAID OBJECT AND FORMING A FILM THEREOF ON SAID OBJECT, AND WITHDRAWING THE THUS COATED OBJECT FROM SAID BATH, THE IMPROVEMENT WHICH COMPRISES INITIATING SAID COATING PROCESS WITH SAID BATH COMPRISING A FLUENT, INTIMATE MIXTURE OF (A) WATER. (B)PIGMENTATION CONSISTING OF AT LEAST ONE COMPONENT PIGMENT, (C)IONIZED, FILM-FORMING, BINDER RESIN FOR PIGMENT AT LEAST THE MAJOR FRACTION OF SAID BINDER RESIN BEING SYNTHETIC POLYCARBOXYLIC ACID RESIN, AND (D) SUFFICIENT WATER SOLUBLE AMINO COMPOUND TO MAINTAIN SAID POLYCARBOXYLIC ACID RESIN AS A DISPERSION OF ANIONIC ELECTROYTE IN SAID BATH.
