摘要：
An electrophoretic medium including a mixture of charge control agents, for example quaternary amine salts of polyisobutylene combined with quaternary amine salts of unsaturated monomers. The described electrophoretic medium exhibits improved color saturation as compared to similar electrophoretic media having only one of the charge control agents.
