ABSTRACT:
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.
