Abstract
An ink-jet recording a water-based ink from an ink chamber through a nozzle hole, wherein the ink chamber contacting with the water-based ink is constructed by jointing plural construction members with an epoxy adhesive, and the water-based in contains a coloring material, a first organic solvent, and a second organic solvent each having properties of a specific organicity and inorganicity. This method enables to enhance the stability of ejection of ink droplets without shortening the life of the head.
Claims19
An ink-jet recording method, comprising the step of:
- jetting a water-based ink from an ink chamber through a nozzle bole to an ink-jet recording media;
