Abstract

Self-dispersing, hardenable epoxy resins produced by reacting one or more α,β-unsaturated carboxylic acid esters with one or more aminopolyalkylene oxide compounds, and reacting the thus formed intermediate with one or more polyepoxide compounds, are described. Processes for their production, aqueous dispersions containing the same and methods for their use are also described.
