ABSTRACT:
An ink containment vessel characterized by improved resistance to the corrosive effects of ink and the ability to prevent air entry into the ink. The system also avoids the evaporative loss of volatile components from the ink supply. The ink containment vessel is produced from a unique multi-layer film product and is designed for use in an ink delivery system. The film includes at least one organic polymer layer and at least one layer of elemental silver. Various organic polymers may be incorporated into the film product in numerous layer arrangements including barrier compositions, sealants, and structural reinforcement materials. Also, an optional layer of a noble metal or hydrophobic compound may be employed to provide further durability. The storage of ink within the vessel offers multiple benefits as indicated above and substantially improves the operational efficiency of the entire ink delivery system.
