    Abstract: Wax dispersion and domain size can be effectively controlled by incorporating a small amount of a hybrid resin binder and or a wax compatibilizer in the toner formulation. Such toners show smaller wax domain size and improved fusing offset window, fusegrade and filming resistance, and therefore improved print quality and reliability. The hybrid resin contains a polyester unit via condensation reaction and a vinyl-based polymer unit via radical polymerization. The hybrid resin is highly compatible with the polyester resin binder, and at same time, can well accommodate low molecular weight polyolefin waxes in the vinyl polymer entity enabling a desirable smaller wax domain size. The wax compatibilizer is a thermoplastic styrenic block copolymer.

    Abstract translation: 可以通过在调色剂配方中加入少量的杂化树脂粘合剂和/或蜡相容剂来有效地控制蜡分散和结晶域尺寸。 这种调色剂显示出较小的蜡区域尺寸和改进的熔合偏移窗口，保险丝和抗成膜性，因此提高了打印质量和可靠性。 混合树脂通过缩合反应含有聚酯单元和通过自由基聚合的乙烯基类聚合物单元。 混合树脂与聚酯树脂粘合剂高度相容，并且同时可以很好地适应乙烯基聚合物实体中的低分子量聚烯烃蜡，从而能够获得理想的较小蜡结构域尺寸。 蜡相容剂是热塑性苯乙烯嵌段共聚物。
