Abstract: A coating composition comprising a high molecular weight polyester, a trimellitic anhydride-polyol adduct and a curing agent is disclosed. The compositions are useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

Abstract: A coating composition includes: (a) 60 to 90 percent by weight of an active hydrogen-containing polyester having a number average molecular weight of at least 23,000, an acid value below 5 and a hydroxyl value below 10, (b) 0.1 to 10 percent by weight of a polyanhydride, and (c) 5 to 30 percent by weight of a curing agent reactive with the active hydrogens associated with (a) and (b), the percentages being based on weight of resin solids of the coating composition, where the reaction product of the coating composition forms a single coating without including a thermoplastic polymer. The coating composition is useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

Abstract: A laminate packaging material has a first film; a first print layer on the first film; a second print layer on the first print layer; an adhesive layer on the second print layer and a second film on the adhesive layer, wherein the second print layer comprises (a) an uncrosslinked polyurethane comprising a member selected from the group consisting of polyester segments and polyether segments; (b) a pigment; and (c) an aminosilane compound comprising at least one member selected from the group consisting of primary amino groups and secondary amino groups.

Abstract: A coating composition comprising (i) a reaction product of two different polyesters, a trimellitic polyanhydride, and a curing agent, for example, an aminoplast; and (ii) an epoxidized polybutadiene polymer. The compositions are useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

Abstract: An aqueous coating composition and a coated packaging material prepared by applying the aqueous coating composition to packaging material comprise poly(vinyl alcohol-vinyl primary amine), poly(methyl vinyl ether-maleic anhydride), and a Ca++ microgranulated bentonite clay. The poly(vinyl alcohol-vinyl primary amine) is about 90-98.5 weight percent and the combined weight of poly(methyl vinyl ether-maleic anhydride) and the Ca++ microgranulated bentonite clay is from about 1.5-10 weight percent of the coating formed on the packaging material. The weight ratio of the poly(methyl vinyl ether-maleic anhydride) to the Ca++ microgranulated bentonite clay is from about 20:80 to about 80:20. The poly(methyl vinyl ether-maleic anhydride) is at least 0.8 weight percent of the coating formed on the packaging material and/or has a weight average molecular weight of at least about 1,000,000 Daltons. The applied coating composition is dried at a temperature of up to about 50° C. to form the coated packaging material.
