Definitions
- the present invention relates to a pigment-based ink composition used in an ink jet recording method.
- pigments are basically insoluble in aqueous and organic solvents. Therefore, in the case of the pigment-based ink, it is necessary to stably and finely disperse the pigment in the medium.
- the pigment-based ink composition must satisfy the performance generally required for an ink composition for ink jet recording. Absent. For example,
- Discharge conditions (drive voltage of piezoelectric element, drive frequency, shape and material of discharge orifice, discharge orifice diameter, etc.) It must have physical properties (viscosity, surface tension, conductivity, etc.) suitable for
- the present invention provides better ink jet recording. It is intended to provide an ink composition.
- the present invention has as its object to provide an ink composition having a small amount of print glaring peculiar to a pigment-based ink composition.
