| description | The invention provides a polyester composition for a toner, a toner and an electrostatic image contrast. The polyester composition disclosed by the invention is prepared from an acid component and an alcohol component as raw materials by esterification and polycondensation reaction, wherein the content of a terephthalic acid is 80.0-94.0wt% and the content of an m-phthalic acid is 6.0-20.0wt% in the gross of the acid component; the content of ethylene glycol is 50.0-80.0wt% and the content of 1,4-cyclohexanedimethanol is 20.0-50.0wt% in the gross of the alcohol component. The polyester composition disclosed by the invention is used as bonding resin for the toner, the problem of reduced image density in a high-temperature and high-humidity environment can be restrained, and the polyester composition has excellent fixation property and heat deviation resistance. |
