FILLING SOLUTION FOR INK SUPPLYING SYSTEM

摘要

A filling solution for an ink supplying system is provided to prevent a discharging failure of ink, which is caused when ink solution is replaced with the filling solution, by forming the filling solution in a composition containing organic solvent having a boiling point of 200 deg.c or above and a fluorinated surfactant. A filling solution for an ink supplying system comprises an organic solvent having a boiling point of 150 deg.c and a fluorinated surfactant. An organic solvent of the ink solution and the organic solvent of the filling solution include glycol. The organic solvent includes organic amine. The fluorinated surfactant is provided in a cation type or an anion type. The filling solution includes 10 to 10000 ppm of the fluorinated surfactant. The filling solution has a surface tension of 15 to 26mN/m.
