WATER-BASED PIGMENT INK, METHOD FOR INK-JET RECORDING WITH THE INK, AND INK-JET APPARATUS EMPLOYING THE INK

摘要

PURPOSE:To obtain the title ink with which a high-quality recorded image with excellent fixability can be obtained on sheets of plain paper having a relatively wide range of material properties. CONSTITUTION:This pigment ink comprises at least water, a water-soluble organic solvent, and a pigment dispersion, and has a surface tension of 35 dyne/cm or higher. The adhesion tension between the ink and a receiving material (Tcostheta) satisfies the equation (-10dyne/cm)
