Abstract: Multi-component composite latex particles used in color toner were prepared by the mini-emulsion polymerization method. The multi-component composite latex particles were composed of organic pigment PY-17，polyethylene wax and coating material polystyrene. The particle size and distribution of composite latex particles were studied with particle size analyzer，the morphology of the latex particles was studied with transmission electron microscopy （TEM），and the thermal and optical properties of the composite latex particles were studied with thermal gravimetric analyzer and UV-visible spectrophotometry. The effects of types and contents of emulsifiers，contents of organic pigment and contents of polyethylene wax on particle size and morphology of the composite latex particles were studied，and the thermal and optical properties of the composite latex particles were characterized. Composite latex particles with small particle size，uniform size distribution and complete coating could be prepared by using compounded emulsifiers，less than 8% of organic pigments and less than 10% of polyethylene wax based on the content of monomer with change in the thermal and optical properties of the composite latex particles.
