摘要: Coating bath compositions and processes useful in depositing organic polymeric coatings on metal substrates at low voltages are provided, the baths comprising one or more dispersed organic film forming polymers; and an etchant; wherein the principle film forming polymer is stabilized in the bath by the presence of anionic surfactant, but can be readily anodically deposited under low voltage. The invention also relates to processes of depositing a coating and metal substrates coated using the baths and processes of the invention.
