Abstract
Abstract Adducts of an active acrylic compound and an amino-amide of monomeric fatty compounds which is a new curing agent for epoxy resins, particularly suitable for curing such epoxy resins in aqueous systems. The agents find utility in coatings systems such as paints but are useful in any area where thermoset epoxy systems find utility.
