Dispersion polymerisation process for producing colored toner particles comprising admixing a colorant with a monomer to form an oil soluble organic phase, admixing a polymerisation initiator with the organic phase, admixing the organic phase with an aqueous phase containing a suspending agent and an inorganic salt therein under polymerisation conditions to form a suspension, polymerising the suspension under continuous agitation to provide polymer particles containing the colorant and having a particle size in the range of from about 1 micron to about 100 microns, and recovering the polymer particles. The inorganic salt inhibits polymerisation in the aqueous phase. Developer compositions and processes for developing electrostatic latent images are also disclosed.
生产彩色调色剂颗粒的分散聚合工艺,包括将着色剂与单体混合以形成油溶性有机相,将聚合引发剂与有机相混合,在聚合条件下将有机相与含有悬浮剂和无机盐的水相混合以形成悬浮液,在连续搅拌下使悬浮液聚合以提供含有着色剂且粒度在约 1 微米至约 100 微米范围内的聚合物颗粒,并回收聚合物颗粒。无机盐可抑制水相中的聚合反应。此外,还公开了用于显影静电潜影的显影剂组合物和工艺。
