ABSTRACT:
A paint comprising as a film-forming component a resinous substance obtained by reacting maleinized polybutadiene containing an unsaturated group and having a low degree of polymerization with a diamine compound containing a primary and a secondary amino group. The resinous substance can be readily rendered water-soluble, and is useful as water-base paints, particularly electrodeposition paints that deposit on the cathode. In place of the maleinized polybutadiene, maleinized drying oils or semi-drying oils or maleinized petroleum resins can also be used.
