INK FOR INK JET PRINTER, METHOD FOR REMOVING DISSOLVED GAS FROM INK FOR INK JET PRINTER, AND PRODUCTION OF INK CARTRIDGE FOR INK JET PRINTER

摘要

PROBLEM TO BE SOLVED: To provide an ink for ink jet printers having a very low dissolved gas concn., to efficiently remove dissolved gases from the ink, and to obtain an ink cartridge for ink jet printers contg. a very low amt. of dissolved gases in the ink or a very low amt. of air bubbles in the cartridge. ;SOLUTION: The total dissolved gas concn. of this ink is 2,950 ppb or lower. Dissolved gases are removed from an ink for ink jet printers with a hollow yarn membrane for degassing. The hollow yarn membrane is installed in an ink-filling route to an ink cartridge to remove the dissolved gases, reducing the total dissolved gas concn. to 2,950 ppb or lower.;COPYRIGHT: (C)1999,JPO
