Zusammenfassung:The invention discloses an environment-friendly pigment particle which contains the following raw materials in parts by weight: 30-50 parts of phthalic nitrile, 10-16 parts of copper, 90-120 parts ofethylene glycol, 1-5 parts of a catalyst, 5-10 parts of an organic medium, 0.05-0.1 part of a surfactant, 0.02-0.07 part of a thickening agent, 0.005-0.015 part of a dispersing agent, 0.01-0.08 part of a wetting agent, 0.4-0.9 part of a water-based resin, 0.025-0.05 part of molybdenum anhydride and 0.2-0.6 part of deionized water. The invention further provides a preparation process of the environmental-friendly pigment particle. The problem that the environment is polluted in the preparation process is solved, the processed and produced phthalocyanine green pigment is clean, environment-friendly and less in side reactions, and the coloring power, brightness, dispersion property and transparency are improved. Moreover, the preparation process is high in operability, the steps are tightly combined, and the process
