A coating resin composition composed mainly of an epoxy resin derivative obtained by reacting an amine compound containing hydroxyl groups, secondary amino groups and amide groups in a molecule with an epoxy resin in its epoxy groups. The resin composition can be used alone, or in the combination with an epoxy resin containing, per molecule, on the average at least 2 epoxy functional groups each comprising an epoxy groups directly bound to an alicyclic ring and/or bridged alicyclic ring, and is useful in a cationically electrodepositable paint.
