Abstract:
1. A system for ink-jet recording comprising (i) an ink-jet recording apparatus including an ink passage, (ii) a water-based ink to be filled in the ink passage during ink-jet recording, and (iii) a preservation solution to be filled in the ink passage at a time of shipping or long-term storage, wherein the ink-jet recording apparatus further comprises a rubber member in said ink passage, said rubber member being formed from a rubber which is formed of a butyl rubber polymer, a rubber polymer vulcanizable with an organic peroxide, and an organic peroxide, wherein the water-based ink includes at least a coloring agent, water and a water-soluble organic solvent, and has a dynamic surface tension at a lifetime of 100 ms of about 35 mN/m to about 45 mN/m as measured by means of a maximum bubble pressure method at a measurement temperature of 25° C., and wherein the preservation solution includes at least water and a water-soluble organic solvent, and has a dynamic surface tension at a lifetime of 100 ms of about 30 mN/m to about 35 mN/m as measured by means of the maximum bubble pressure method at a measurement temperature of 25° C.
