Aqueous compositions suitable for use as sanitary container coatings are prepared by reacting epoxy resin and a carboxyl containing acrylic resin in the presence of a polyfunctional tertiary amine. The compositions made with polyfunctional amine have lower viscosities than those made with monofunctional amine, an advantage in preparing high solid coatings for roll application, for example.

Aqueous coating compositions and process for their preparation from

A method for reducing extractable constituents of an undesirable monomer in compositions which comprise an ionic polymer and an addition polymer of the undesired monomer which comprises conducting an addition polymerization in the presence of the undesired monomer with another monomer which is copolymerizable therewith and which results in a less undesirable residue or a residue which is more easily removable, is disclosed.

Aqueous coatings comprising ionic polymer ester and diluent polymer with

Aqueous compositions suitable for sanitary can coatings comprising the neutralized water dispersible ionic polymer product of the reaction of an epoxy resin with acid polymer, and a different resin which is not necessarily self-dispersible in water, as well as several methods of preparing such compositions, are disclosed. The second resin which is not necessarily self-dispersible in water is introduced either preformed at any stage or is prepared, in situ, in the presence of the epoxy resin esterified with acid polymer either before the ionic epoxy resin-acid polymer product is dispersed in water. The epoxy resin-acid polymer product acts as a polymeric surfactant capable of keeping even a normally non self-dispersible second polymer in stable dispersion in water.
