This invention discloses a modified organic black dye and its preparation method, relating to the field of dye modification technology. The preparation method includes the following steps: (1) chemically modifying the organic black dye with a linker to obtain a modified black dye; (2) preparing polymer microspheres using a soap-free emulsion polymerization method; (3) chemically bonding the modified black dye obtained in step (1) with the polymer microspheres obtained in step (2) to obtain a spherical modified organic black dye. The preparation method of this invention combines the organic black dye with polymer microspheres through chemical bonds to form a spherical dye, improving the dye morphology and enhancing its flowability and dispersion uniformity. Furthermore, the polymer microspheres prepared using the soap-free emulsion polymerization technology of this invention have controllable particle size and good monodispersity, resulting in uniform particle size of the final dye particles, making them suitable for applications with strict particle size requirements.
