preparation example Construction

[0037] The granular resin (A) can be prepared by a known method such as the method disclosed in the Examples of JP-A 2001-181544.

[0038] The present invention prepares ink-jet printing ink method to comprise:

[0039] adding a self-emulsifiable polyurethane aqueous emulsion to the pigment dispersion (in the pigment dispersion, including pigment, dispersant and water) to prepare a first mixture;

[0040] stirring the first mixture mixture (preferably for 10 minutes or longer);

[0041] Adding granular resin (A) dyed with a fluorescent dye and having an average particle size of 50-200nm to the first mixture to prepare a second mixture;

[0042] stirring the second mixture (preferably for 10 minutes or longer); and

[0043] Additives selected from the group of substances consisting of wetting agents, surfactants, antifoaming agents, anti-seepage agents, pH regulators and preservatives are optionally added.

[0044] The pigment dispersion was prepared as follows:

Abstract

An ink-jet ink including a pigment a dispersant, a water, a particulate resin (A) dyed with a fluorescent dye and having an average particle diameter of from 50 to 200 nm, and an emulsion of a self-emulsifiable polyurethane; and a method for preparing the ink-jet ink, an ink cartridge containing the ink-jet ink, an image forming method using the ink-jet ink, and an image formed with the ink-jet ink.

Description

field of invention [0001] The present invention relates to inkjet inks for inkjet printers. In addition, the present invention relates to a method of producing an inkjet ink, a cartridge comprising the inkjet ink, an image forming method using the inkjet ink, and an image formed with the inkjet ink. Background technique [0002] An ink in which a water-soluble dye is dissolved in water or a mixture of water and a water-soluble solvent has heretofore been mainly used in the inkjet recording method. [0003] However, images printed on recording materials using this dye-based ink have a problem of poor water fastness. If water is spilled on the image, the dye tends to leak. Another problem is that images have poor light fastness. If an image is exposed to light, the color tone tends to change and the image density tends to decrease. [0004] In order to solve the above-mentioned problems of dye-based inks, there are proposals to use pigment-based inks in which carbon black ...
