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： The invention provides colored fine resin particles useful as coloring materials for inks which can provide images having good water fastness, weather fastness and rub-off resistance and are excellent in dispersion stability, and a production process thereof. The colored fine resin particles have a structure in which a pigment coated with a water-insoluble resin is encapsulated with a copolymer composed of at least a polymerizable unsaturated monomer and a reactive emulsifier.
