Abstract

Disclosed is a process for enabling improved fixing of toner compositions wherein the components thereof are modified enabling hydrogen bonding to cellulose materials, including paper. This can be accomplished by incorporating into the toner composition various modified resins, such as those commerically available from Hercules as Stabelite Ester 10, Pentalyn H, and Foral 105. Alternatively, these can be incorporated into the toner composition lower molecular weight polyethylene-acrylic acid copolymers with high acid numbers, including materials commerically available from Allied Chemical as Allied AC5120.

Disclosed is a process for enabling improved fixing of toner compositions wherein the components thereof are modified enabling hydrogen bonding to cellulose materials, including paper. This can be accomplished by incorporating into the toner composition various modified resins, such as those commerically available from Hercules as Stabelite Ester 10, Pentalyn H, and Foral 105. Alternatively, these can be incorporated into the toner composition lower molecular weight polyethylene-acrylic acid copolymers with high acid numbers, including materials commerically available from Allied Chemical as Allied AC5120.

These compositions are particularly useful in imaging systems wherein the toner is fixed by cold pressure processes. With the compositions and the processes disclosed improved fixing of the toner component results in that there is achieved increased adhesion to paper.

Examples of toner compositions that are envisioned include those containing pigment particles, and various known thermoplastic polymers, such as styrene methacrylate, styrene acrylates, styrene butadienes, polymer blends styrene acry- lates having incorporated therein low molecular weight waxes, and terpolymers of styrene, acrylonitrile, and butyl acrylates.
