  A toner includes binder of amorphous polymer material, such as an amorphous polyester material, and a crystalline polymer material, such as a crystalline polyester material, wherein the amorphous polymer material has an acid number that is greater than an acid number of the crystalline polymer material. Further, the toner may have a minimum fusing temperature of from about 75°C to about 150°C and a relative humidity sensitivity of from about 0.5 to about 10. A method of making toner particles is also indicated.

  调色剂包括无定形聚合物材料（如无定形聚酯材料）和结晶聚合物材料（如结晶聚酯材料）的粘合剂，其中无定形聚合物材料的酸数大于结晶聚合物材料的酸数。此外，调色剂的最低熔融温度为约 75°C 至约 150°C，相对湿度敏感度为约 0.5 至约 10。还指出了一种制造墨粉颗粒的方法。

  A process for making a resin emulsion suitable for use in forming toner particles includes melt mixing a resin possessing acid groups at a temperature higher than the glass transition temperature of the resin, optionally adding a surfactant before, prior to, during, or after melt mixing the resin, and adding a basic neutralization agent and water to the resin to form an emulsion. In embodiments, the resin emulsion thus produced may be utilized to form a toner.

  制造适用于形成调色剂颗粒的树脂乳液的工艺包括：在高于树脂玻璃化温度的温度下熔融混合具有酸性基团的树脂，可选择在熔融混合树脂之前、期间或之后添加表面活性剂，并向树脂中添加碱性中和剂和水以形成乳液。在实施例中，由此产生的树脂乳液可用于形成调色剂。

  The present disclosure provides methods for modifying polymeric resin materials after polymerization to make fine adjustments in the chemical or physical properties of the resin, or in modifying the structure of the polymer chains. The resulting resins may be useful in forming toner particles. In embodiments, a polymeric resin may have epoxy groups added to its backbone to increase its melting point. The resulting polymer, sometimes referred to herein as an epoxidized polymer, may, in turn, be reacted with wax-like components, to increase the compatibility of the polyester with waxes utilized in forming toner particles. In other embodiments, the resulting epoxidized polymer may be reacted with components possessing carboxylic acid groups to adjust the acid value and weight average molecular weight of the resin.

  本公开提供了在聚合后对聚合树脂材料进行改性的方法，以对树脂的化学或物理特性进行微调，或对聚合物链的结构进行改性。所得树脂可用于形成墨粉颗粒。在具体实施中，聚合物树脂的骨架上可添加环氧基团，以提高其熔点。由此产生的聚合物（有时在此称为环氧化聚合物）可反过来与蜡状成分反应，以提高聚酯与用于形成墨粉颗粒的蜡的相容性。在其他实施方案中，生成的环氧化聚合物可与具有羧酸基团的成分反应，以调整树脂的酸值和重量平均分子量。
