Abstract: There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component, including—2,2,4,4-tetraallcylcyclobutane-1,3-diol. One of the polyacid component or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a metal packaging containing coated with the composition.

Abstract: Printers' ink liquid work product transfer apparatus is provided to transfer raw printers' ink work product stored in drums to a remote location for processing into finished commercial printers' ink. The mechanism includes means to provide substantially simultaneous operations comprising: rotating the drum; scraping product residue from the interior wall surface of the drum; pumping the work product from the drum; and lowering the nozzle of a pump connected work product inlet tube in a work product-filled drum at the same rate that the level of the work product is lowered in the drum by pumping action. When the nozzle of the work product inlet tube reaches the bottom of the drum, the work product in the drum will have been substantially completely emptied of work product.
