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 composite color toner image can be enhanced by applying a separate fluorescing toner image over it to provide an enhanced color toner image having a “pinkish” fluorescing effect. This separate fluorescing toner image is obtained using visible fluorescing dry magenta toner particles. Each of these toner particles consists essentially of a polymeric binder phase and a visible fluorescing colorant that emits at one or more peak wavelengths of at least 510 nm and up to and including 590 nm and that is dispersed within the polymeric binder phase.
