Abstract

Disclosed are toner compositions comprised of resinous plastic materials containing polar groups, such materials being useful in electrophotographic imaging systems. These materials which are useful as toners have desirable insulating and/or tribo-electric properties and allow the use of certain plastic materials as toners by introducing certain groups into these materials for the purpose of improving their insulating and/or triboelectric characteristics. These toners are prepared by introducing polar (dipole) materials into both thermosetting and thermoplastic compositions. Addition of the polar groups can be accomplished by blending polar additives into non-polar plastics and by synthesizing plastics with polar functional-ity. The plastic materials can be selected from a number of organic compounds including silicone oligomers and polymers, aromatic oligamers and polymers, polyacrylic acids, metha-crylic acids and esters thereof as well as copolymers thereof, aliphatic amorphous hydrocarbons, phenoxy oligomers, and polymers of poly ortho, meta, and para-phenoxy compounds; triazine and cyanuric acid derivatives while the polar groups may be selected from various materials including alcohols, methyl hydroxides, carbon chlorine compounds, carbonyl com-pounds, hydroperoxides, organic acids and the metal salts thereof, halides, esters, ethers, epoxys, quaternary amines, hydroxyl compounds, phenolic compounds, and the metal salts of the hydroxyl and phenolic compounds. These compositions which have polar groups present in concentrations of from about 0.1 to about 20 mole percent, in a preferred embodiment are useful as toners for developing images in an electrostatic latent image system.

are useful as toners have desirable insulating and/or tribo-

can be accomplished by blending polar additives into non-polar
