Abstract
Abstract The present invention concerns a coating composition comprising a dispersion, solution or suspension of a coating composition containing a nitrogen containing organic material which when heat cured contains at least 75% less amine value than present in the material prior to curing. The present invention also concerns a method of electrodepositing a film forming substance onto a substrate by employing an anode, a cathode and an electrolyte therebetween comprising the steps: a. providing an aqueous electrolyte containing said composition described above; b. closing the circuit between the anode and the cathode; and c. depositing the film forming composition on the cathodic substrate.
