INK-JET INK AND METHOD FOR FORMING IMAGE
This ink-jet ink (hereinafter, referred to as "ink") comprises an aqueous solvent, a pigment, and a thixotropic agent, and is characterized by having a viscosity at 25°C of 15 mPa·s or lower at a shear rate of 1,000 (1/s) and having a viscosity at 25°C of 150 mPa·s or higher at a shear rat...

| description | This ink-jet ink (hereinafter, referred to as "ink") comprises an aqueous solvent, a pigment, and a thixotropic agent, and is characterized by having a viscosity at 25°C of 15 mPa·s or lower at a shear rate of 1,000 (1/s) and having a viscosity at 25°C of 150 mPa·s or higher at a shear rate of 1 (1/s) in a state in which the aqueous solvent has been removed therefrom so that the mass of the ink is 80% of the initial mass. This method for forming an image includes an ink delivery step in which droplets of an ink are ejected from an ink-jet head equipped with an ink circulation mechanism and are delivered to a base, and is characterized in that the ink comprises an aqueous solvent, a pigment, and a thixotropic agent, the ink is circulated so that the ink within the ink-jet head has a viscosity of 15 mPa·s or lower, and the ink delivery step is conducted so that the droplets at the time of delivery to the base or immediately after the delivery have a loss in mass from the ink of 20% or less and have a viscosity of 150 mPa·s or higher. |
