Abstract
Novel compositions of matter comprising a water-dispersible reaction product of beta-diketones and epoxy material are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water and they can be formulated optionally with curing agents. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion-resistant properties.
