In order to obtain black UV-LED inkjet ink with excellent dispersion, the color paste samples were prepared by grinding with different monomers and mixed monomers, respectively, and the particle size of color paste was tested to investigate the influence of monomers on ink dispersion. The results showed that for the carbon black pigment, the color pastes prepared by different monomers exhibit different dispersions. The black UV-LED inkjet inks prepared by monomer HDDA or EOEOEA alone had small particle size,which revealed inks' dispersions are better. The dispersion of black UV-LED ink jet ink prepared with a mixed monomer HDDA:EOEOEA = 1: 1 was the best of all.
