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.
