Abstract: The present invention provides novel packaging articles, e.g., food and beverage cans. Preferred cans typically comprise a body portion and an end portion, wherein at least one of the body and end portions are aluminum and are coated on at least one major surface with a coating composition of the present invention. Suitable coating compositions of the present invention comprise: one or more polyester resins, wherein at least one of the polyester resins has a glass transition temperature (“Tg”) less than about 50° C., and wherein the polyester resin is formed by the reaction of one or more polyacid molecules and one or more polyol molecules; and a crosslinker. The present invention also provides a method of making such cans.

Abstract: Methods for preparing crosslinking agents that are the ungelled reaction product of (a) at least one aminoplast resin and (b) at least one modifying compound, wherein the crosslinking agents are essentially free of active hydrogen functional groups and have a glass transition temperature of at least 10° C. are disclosed. The methods include, inter alia, the use of vacuum and/or increased rates of inert gas introduction during reaction.

Abstract: Thermosettable prepolymers or resins are prepared by reacting (1) a pyrazine compound containing at least two substituent groups which have a hydrogen atom attached to a carbon atom which is attached to the ring such as tetramethylpyrazine, (2) a material containing at least two aromatic aldehyde groups, and (3) at least one of (a) a nitrogen containing aromatic heterocyclic compound containing at least one hydrogen atom attached to a carbon atom attached to the ring and a polymerizable unsaturated group such as 2-methyl-5-vinylpyridine or (b) an aldehyde containing at least one polymerizable unsaturated group such as 4-isopropenyl-1-cyclohexene-1-carboxaldehyde. These prepolymers or resins are curable to thermoset products having good mechanical and thermal properties by heat and pressure or by homopolymerization or copolymerization with N,N'-bis-imides such as 1,1'-(methylenedi-4,1-phenylene)-bimaleimide. The prepolymers are suitable for preparing composites.

Abstract: Disclosed is a UV-curable coating composition and method of preparing it, a method of coating a conductor with it, and the resulting coated conductor. The composition comprises about 20 to about 40% by weight of an acrylated epoxy which is the reaction product of an epoxy resin and an acrylate adduct. The acrylate adduct is the reaction product of an acrylate which may be either 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 2-hydroxyethyl methacrylate or mixture thereof, and either an anhydride or a diisocyanate. The anhydride may be phthalic anhydride, maleic anhydride, trimellitic anhydride, or mixtures thereof. The diisocyanate can be toluene diisocyanate, 4,4'-diisocyanato diphenyl methane, or mixtures thereof. The composition also includes about 4 to about 15% by weight of an acrylated blocked isocyanate which is the reaction product of caprolactam and an acrylated isocyanate.

Abstract: Aqueous dispersions of mixed resins are prepared by polymerizing in the presence of an aminoplast resin a mixture of polymerizable carboxylic acid monomers and other monomers, adding to the polymerization product an epoxy resin, adding ammonia or an amine to salt the acid groups and dispersing the resin mixture in water. The aqueous dispersions are useful as can coatings.

Abstract: Fibrous-reinforced composites, such as prepregs and sheet moulding compounds, are made with a thermosettable unsaturated polyimide resin, a photopolymerizable compound, and a heat-activated curing agent for the resin. Fibers may be impregnated with a liquid mixture of the resin and the photopolymerizable compound, and irradiated to cause the mixture to solidify through photopolymerization. The product, when desired, e.g., after stacking to form a multilayer laminate or after shaping, is heated to cure the resin. Alternatively, the liquid mixture is irradiated to form a solid film, into which the fibers are pressed, and, when required, the assembly is heated to cure the resin. The resins employed contain at least two maleimide, citraconimide, or itaconimide groups linked through nitrogen atoms thereof to carbon atoms.
