Abstract
An alkyd-type electrodepositable coating composition derived from the reaction of a base alkyd with ethylenically unsaturated monomers including an amine-functional monomer is provided with improved resistance to chipping by chemically incorporating in it by covalent bonding one or more chemical agents selected from the group of: (a) preformed elastomers having functional groups reactive with carboxyl or hydroxyl groups of acid and polyol alkyl precursors, and (b) an addition polymerizable monomer having primary and secondary ethylenic unsaturation.
