摘要： A toner composition and a xerographic process for making lithographic plates using the toner composition is provided. The toner composition can be prepared in the form of a dry powder, a polymeric limited coalescence composition, or an evaporative limited coalescence composition. The toner composition absorbs light in the frequency range of 300 to 450 nm and has a total transmission density of at least about 3 at a stack height of about 10 microns. Positive transparencies are produced with imaged areas formed from the toner composition using conventional photocomposing. The transparencies are then employed for contact exposing of positive-working lithographic plates with light, and the plates are then developed.

摘要： A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of a pigment by depositing thereon a coating of a low melting point wax. The method involves preparing a mixture of a wax solution and a pigment dispersion which is heated to a temperature sufficient to assure dissolution of wax and permitting the mixture to cool slowly to room temperature at which point a coating of wax is deposited upon the surface of the pigment. The wax coated pigment particles are then used as a component of the organic phase in a limited coalescence process.
