Abstract: Monoethylenically unsaturated polymerizable monomers carrying a plurality of ketimine-blocked primary amine groups are disclosed. These are preferably provided by reacting an organic diisocyanate with the single secondary amine group of a ketimine-blocked diprimary amine carrying a single secondary amino hydrogen atom and then reacting a monohydric acrylate with the other isocyanate group.

These dispersions will electrodeposit at the cathode.
