摘要:
The present invention provides a dispersible colorant having a sufficiently high dispersion stability with a high functional group density on the surface and a resin component present on the surface, the resin component not separating from the surface, and a method for simply producing the same. The present invention also provides an aqueous ink containing the excellent, dispersible colorant, ink tank, ink jet recorder, ink jet recording method and inkjet recorded images. The dispersible colorant comprises a colorant and chargeable resin pseudo fine particles having a smaller size than the colorant, and the colorant and particles are fixed to each other.
摘要:
Provided are an aqueous ink containing: water; multiple water-soluble organic solvents; and a dispersible colorant, the aqueous ink containing a good medium with respect to the dispersible colorant and a bad medium with respect to the dispersible colorant as the water-soluble organic solvents, in which: the dispersible colorant is a dispersible colorant having a colorant and chargeable resin pseudo fine particles each of which is smaller than the colorant in which the colorant and the chargeable resin pseudo fine particles fix to each other; and when a total amount of the good medium in the ink (mass %) is denoted by A and a total amount of the bad medium in the ink (mass %) is denoted by B, A:B is in the range of 10:5 to 10:30.
摘要:
A dispersible colorant is provided which comprises a colorant and a chargeable resin pseudo fine particle of a size smaller than the size of the colorant being fixed or fused to the colorant, wherein the colorant itself has a surface charge. Thereby, it becomes possible to process a surface of the colorant while exploiting both the characteristic of a resin adhered and fixed to the surface of the colorant and the characteristic of the surface of the colorant, so that it is possible to provide a dispersible colorant that has sufficiently high dispersibility and a simple and easy method of producing the colorant, by use of a colorant that is essentially water-insoluble.

摘要:
A dispersible colorant suitable for ink-jet recording ink is manufactured by a method using aqueous precipitation polymerization. The ink has high dispersion stability and can form a high-quality image excellent in fastness properties. The method includes at least a dispersing step of dispersing a colorant into an aqueous solution by means of a dispersant, an aqueous precipitation polymerization step of adding a resin monomer and a radical polymerization initiator to the solution into which the colorant is dispersed to manufacture a dispersible colorant having a chargeable resin pseudo-fine particle, fixing thereon by means of aqueous precipitation polymerization, and an ultrafiltration step of subjecting the aqueous solution containing the dispersible colorant to ultrafiltration to obtain the dispersible colorant.

An aqueous ink is provided which comprises a dispersible colorant comprising a colorant and chargeable resin pseudo fine particles smaller than the colorant, the colorant and the chargeable resin pseudo fine particles fixing to each other; and at least one of a water-soluble nonionic resin and an emulsion particle. As a result, it becomes possible to provide an aqueous ink suitable for ink jet recording which has high dispersion stability, is excellent in long-term dispersion stability, and is capable of providing an image excellent in fastness such as rubfastness, especially a highly glossy image. Further, there can also be provided an ink tank, an ink jet recording apparatus, an ink jet recording method, and an ink jet recorded image each using such aqueous ink.
摘要:
A dispersible colorant, including a colorant and a chargeable resin pseudo fine particle having a sulfonic group, which is smaller than the colorant, in which the sulfonic group of the dispersible colorant has a surface functional group density of 100 μmol/g or more, is provided. The dispersible colorant has sufficiently high dispersion stability without causing detachment of the resin component from the colorant, while retaining long-term stability. The use of the dispersible colorant allows an aqueous ink-jet recording ink, which is excellent in discharge stability, an ink tank, an ink-jet recording apparatus, an ink-jet recording method, and an ink-jet recording image to be provided.
