摘要： Non-gelled compositions containing hydroxy ester copolymer having carboxyl groups and substantially free of oxirane groups are disclosed which are the esterification reaction product of(A) acidic addition copolymer; and(B) mixtures containing epoxy resin including both aromatic polyether containing oxirane groups and aromatic polyether devoid of oxirane groups, in which the mixture comprises at least 40% of the total resin solids and contains insufficient oxirane groups to react with all of the carboxyl groups in the copolymer. The resulting composition is neutralized with amine, is self-emulsifiable in water and is useful for coating, e.g., for cans.

摘要： There is disclosed a metal container containing a beverage or food having its internal surface coated with an adherent sanitary liner, the coating being a cured layer of a water-based coating composition consisting essentially of from about 5 percent to about 60 percent by weight of an amine-neutralized or partially neutralized interpolymer formed in the presence of a vinyl polymerization catalyst and in the absence of mercaptan, the interpolymer being comprised of from about 10 percent to about 30 percent of acrylamide or methacrylamide in units of the structure: ##STR1## where R' is methyl or hydrogen and R is hydrogen or lower alkyl, from about 5 percent to about 15 percent of units formed by vinyl polymerization of monoethylenically unsaturated carboxylic acid; from about 10 percent to about 30 percent of units derived by vinyl polymerization of monovinyl aromatic monomer; from about 10 percent to about 30 percent of units formed by vinyl polymerization of flexibilizing monomer selected from lower alkyl acrylates such as ethyl acrylate; and from about 20 percent to about 45 percent of nitrile, such as acrylonitrile; wherein the interpolymer is solubilized by neutralizing acid groups of the interpolymer with a sufficient amount of monomeric amine to produce at least 0.200 milli-equivalents of salt per gram of resin solids; and from about 40 percent to about 95 percent by weight of a liquid medium consisting of a mixture of water-soluble or water-miscible organic solvents and water, wherein at least 60 percent by weight of the mixture is water. These cured coatings are characterized by improved impermeability to lubricants and flavor components and also better resist water at elevated temperature so as to also be useful as an exterior coating.

摘要： 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.

摘要： 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.

摘要： A coating composition particularly adapted for can coatings is prepared by the addition polymerization of a monomer such as styrene in a reaction medium comprising a modified 1,2 epoxy resin. The epoxy resin is modified by combining a portion of its 1,2-epoxy groups with epoxy-reactive groups of an ethylenically unsaturated monomer, and reacting others of its 1,2-epoxy groups with a tertiary amine and with a preformed addition polymer containing carboxyl groups to form an ionic, resinous composition containing sufficient carboxyl groups to render the coating composition self-dispersible in water in neutralized form.
