Title:
AQUEOUS PIGMENT DISPERSION FOR INK, INK-JET RECORDING INK, INK TANK FOR INK-JET RECORDING, INK-JET RECORDER AND INK-JET RECORDING METHOD
Document Type and Number:
Japanese Patent JP2006342202
Kind Code:
A
Abstract:
To obtain an aqueous pigment dispersion for imparting excellent fixing properties even in using pigment as a colorant, ink-jet recording ink and to provide an ink tank for ink-jet recording, an ink-jet recorder and an ink-jet recording method.
The aqueous pigment dispersion for ink comprises at least pigment, a carboxy group-containing polymer, a nonionic surfactant and water. The carboxy group-containing polymer is dissolved in an aqueous solution of a nonionic surfactant-containing basic compound and an acidic compound is added to the aqueous solution to form a polymer fine particle. The volume-average particle diameter of the polymer fine particle is 10-300nm.
