    • PURPOSE: A polyester resin for a toner binder, a method for manufacturing the same, and a toner including the same are provided to obtain low temperature fixation characteristics and off-set characteristics. CONSTITUTION: A polyester resin for a toner binder is obtained by poly-condensing a reactive mixture. The reactive mixture includes relative amounts of 100 mol equivalent of aromatic divalent acid, 5 to 30 mol equivalent of isosorbide, 10 to 50 mol equivalent of aliphatic diol, and 30 to 70 mol equivalent of aromatic diol. The glass transition temperature of the polyester resin for the toner binder is between 60 and 80 degrees Celsius. The water average molecular weight of the polyester resin for the toner binder is between 2500 and 5500g/mol. The softening temperature of the polyester resin for the toner binder is between 95 and 115 degrees Celsius. The aromatic divalent acid is one or more selected from a group including terephthalic acid, isophthalic acid, dimethyl terephthalate, dimethyl isophthalate, diethyl terephthalate, diethyl isophthalate, dibutyl terephthalate, dibutyl isophthalate, and an acid anhydride of the same.
    • 目的:提供用于调色剂粘合剂的聚酯树脂,其制造方法和包含其的调色剂,以获得低温固化特性和偏移特性。 构成:用于调色剂粘合剂的聚酯树脂通过聚合反应混合物的冷凝而获得。 反应性混合物包括相对量的100摩尔当量的芳族二价酸,5至30摩尔当量的异山梨醇,10至50摩尔当量的脂族二醇和30至70摩尔当量的芳族二醇。 用于调色剂粘合剂的聚酯树脂的玻璃化转变温度为60至80摄氏度。 调色剂粘合剂用聚酯树脂的水分子量为2500〜5500g / mol。 调色剂粘合剂的聚酯树脂的软化温度在95和115摄氏度之间。 芳香族二价酸是选自对苯二甲酸,间苯二甲酸,对苯二甲酸二甲酯,间苯二甲酸二甲酯,对苯二甲酸二乙酯,间苯二甲酸二乙酯,对苯二甲酸二丁酯,间苯二甲酸二丁酯等的一种以上的酸酐。
