Abstract: A cathodic sediment type of electrodeposition paint composition which consists of an aqueous medium, a resinous binder dissolved or dispersed therein and an accelerating catalyst. The resinous binder is an acid neutralized reaction mixture of a first and a second component in a weight ratio of 99 to 20 parts of the first component to 1 to 80 parts of the second component. The first component is an addition material of a polybutadiene terminating in an epoxy group and a primary or secondary amino compound. The second component is an addition material of an epoxy resin and a primary or secondary amino compound. The accelerating catalyst is selected from the group consisting of an oleosoluble organic acid salt of a transition metal, the metal in turn being selected from the group consisting of iron, vanadium and titanium.

Abstract: A polyamine/epoxy ether graft copolymer having an acrylic polamine backbone with secondary amine and hydroxy functionality, part of which is terminal primary hydroxy groups, onto which is grafted an epoxy ether. The ether is an epoxy resin preferably reacted with nonylphenol resulting in a monoepoxide ether with one or less epoxy group per epoxy ether molecule. The ether is reacted with part of the secondary amine on the acrylic backbone. This system can be formulated to a nearly-neutral pH cathodic dispersion with good cure response at 150.degree.-175.degree. C. using conventional aminoplast crosslinkers.
