    Abstract: This invention provides a coating composition for use on a food-contact surface of a container (e.g., a food or beverage can) that includes a polymer having one or more segments of Formula I: —O—Ar—Rn—C(O)—O—R1—O—C(O)—Rn—Ar—0— wherein each Ar is independently a divalent aryl group (i.e., an arylene group) or heteroarylene group; R1 is a divalent organic group; each R is independently a divalent organic group; and n is 0 or 1. Containers comprising the polymer and methods of making such containers are also provided.

    Abstract: An improved easily openable end for a metal container, and aL method of manufacturing the end are disclosed. The metal container is manufactured from a can body and two can ends, one of which is easily openable. The easily openable can end is manufactured from a metal substrate having a score line on its external surface that permits easy removal of at least a portion of the can end from the can body. The score line of the easily openable can end is coated with a iradiation-curable coating composition that impa˜ts corrosion resistance along the score line of the easily openable can end.

    Abstract: A low viscosity blocked isocyanate solution can be made by reacting together a polymeric isocyanato compound and propylene glycol, or a polymeric primary or secondary amine and propyl carbonate. The resulting beta-hydroxypropyl urethane polymer can be combined with propylene glycol monomethyl ether as a reducing solvent to form a pourable high-solids solution with good flow properties at room temperature. The solution has lower viscosity than is obtained using ethylene glycol as a blocking agent or using several non-HAPS reducing solvents that are similar to propylene glycol monomethyl ether. The solution can readily be combined with electrodepositable paint ingredients to form a curable coating composition.

    Abstract: Metal food or beverage containers are coated with a polyether polymer containing at least two ether linkages in the polymer backbone. The polymer is substantially free of segments derived from bisphenol A and epoxides thereof, and is a reaction product of, or can be derived from, (i) an aryl- or heteroaryl-group-containing diepoxide that is not derived from a polyhydric phenol or a glycidyl ester and (ii) a polymer backbone extender that has two functional groups reactive with an epoxy group and which following reaction with the diepoxide provides at least one pendant aryl or heteroaryl group on the polymer backbone, or provides at least one divalent aryl or heteroaryl group in the polymer backbone and linked to the backbone via ether linkages.
