    摘要: A process for producing positively charged polymer encapsulated particles which have a size of less than 5 μm and which include a positively charged polymer shell surrounding a core of particle. The process includes the steps of, firstly, dispersing the core particles in an aqueous solution; adding a mixture of monomers either before or after the dispersion step; then, polymerizing the monomers in view of obtaining polymer encapsulated particles, wherein the polymer shell of the particle includes polymers or co-polymers that have a functional group FG. Finally, the process includes the step of dispersing the encapsulated particles with surfactants and charge directors in view of obtaining positively charged encapsulated particle dispersions.
