    • A process for producing a polymer toner comprises the steps of pouring a polymerizable monomer composition containing at least a polymerizable monomer and a colorant, but containing no oil-soluble polymerization initiator into an aqueous dispersion medium containing a dispersing agent; adding an oil-soluble polymerization initiator to the polymerizable monomer composition while stirring the composition to form primary droplets thereof, thereby bringing the droplets of the polymerizable monomer composition into contact with droplets of the oil-soluble polymerization initiator to form droplets of a polymerizable monomer composition containing the oil-soluble polymerization initiator; further continuing the stirring to form secondary droplets having desired droplet sizes; and then conducting suspension polymerization of the polymerizable monomer composition.
    • 制备聚合物调色剂的方法包括将含有至少可聚合单体和着色剂但不含油溶性聚合引发剂的可聚合单体组合物倒入含有分散剂的水性分散介质中的步骤; 在搅拌组合物的同时,将可溶性聚合引发剂加入到可聚合单体组合物中以形成其初级液滴,从而使可聚合单体组合物的液滴与油溶性聚合引发剂的液滴接触,形成可聚合单体组合物 含有油溶性聚合引发剂; 进一步继续搅拌以形成具有所需液滴尺寸的二次液滴; 然后进行可聚合单体组合物的悬浮聚合。
