    • A liquid developer for use in electrostatic photography is prepared by blending in a carrier liquid having a high electric resistivity and a low dielectric constant, (1) a resin dispersion composition A comprising a polymer obtained from at least one kind of resin which is difficult to dissolve or insoluble in said carrier liquid and at least one kind of monomer in which said resin is soluble and (2) a coloring agent having a high electric resistivity and consisting essentially of fine particles of pigment coated with a resin B which is different from said resin-dispersion composition A and is substantially insoluble in said carrier liquid. The liquid developer is superior in dispersion stability, polarity controlling property, adhesive property and storage stability and contributes to effecting development manifesting improved fixability as well as transferability.
    • 通过混合具有高电阻率和低介电常数的载体液体制备用于静电摄影的液体显影剂,(1)树脂分散组合物A,其包含由至少一种树脂获得的聚合物,其难以 溶解或不溶于所述载体液体和其中所述树脂可溶的至少一种单体和(2)具有高电阻率的着色剂并且基本上由涂覆有不同于所述树脂B的树脂B的颜料的细颗粒组成 树脂分散组合物A,并且基本上不溶于所述载体液体。 液体显影剂的分散稳定性,极性控制性,粘合性和保存稳定性优异,有助于显现提高定影性和转印性的显影。
