PURPOSE: A method for preparing a particulate coloring resin, a particulate coloring resin prepared by the method, and a coloring method of an article using the coloring resin are provided, wherein the coloring resin is useful as an image recording material, a print ink and a paint. CONSTITUTION: The method comprises the steps of melting a coloring resin obtained by mixing a hot melting resin and a coloring agent uniformly; making the molten coloring resin into the droplet-shaped particles in the medium which does not dissolve the coloring resin; and cooling and solidifying the droplet-shaped particles. Preferably the melting index of the coloring resin is 1-500 Pa·s at a temperature of 80-180 deg.C; the granulation is carried out at a temperature of 80-200 deg.C; and the solidification is carried out at a temperature of -10 to 20 deg.C. 미립자형상 착색수지는 열용융성수지 중에 적어도 색소가 균일하게 분산 또는 용해하여 이루어지는 착색수지를 용융상태로 하는 공정, 해당 용융상태의 착색수지를 해당 착색수지를 용해하지 않은 불용성매체 속에서 액체방울형상의 미립자로 하는 공정, 및 해당 액체방울형상의 미립자를 냉각고화시키는 공정에 의해 제조될 수 있다. 미립자형상 착색수지는 화상기록재료, 인쇄잉크 및 도료에 유용하다. 물품은 화상기록재료, 인쇄 잉크 또는 도료로 착색될 수 있다.
