Patent ID: 10048605

Abstract:
Cold pressure fix toner compositions include at least one crystalline polyester having a melting point in a range from about 30° C. to about 130° C., a rosin acid-based polyester resin and an amorphous polyester having a Tg higher than the rosin acid-based polyester. The crystalline polyester can have a melting point in a range from about 30° C. to about 130° C., the rosin acid-based polyester resin can have a Tg in a range from about 0° C. to about −45° C. and an amorphous polyester having a Tg in a range from about 40° C. to about 70° C. The temperature difference between the rosin acid-based polyester resin and the amorphous polyester resin can be in a range from about 30° C. to about 110° C.
