Modified polyester binder resin with an excellent low-temperature fixability and thermal stability

摘要

the present invention is an aromatic dicarboxylic acid , an aromatic dicarboxylic acid and trivalent or more polyvalent carboxylic acid acid component is selected from the mixture; Aromatic diol ; Aliphatic diol ; And an optional component of the esterification reaction , including three or more polyhydric alcohol components as a polycondensation reaction and the modified polyester resin produced by the reaction and the thermal stability prepared by using it as a binder resin , low-temperature fixing performance , and long-term storage stability relates to an excellent toner .
