摘要： An ultraviolet light absorbing polyester resin and toner particles incorporating such polymer are provided. The toner particles are particularly useful in photolithographic applications wherein ultraviolet light is used for making printing plates from color separation transparencies which contain imaged areas defined by the toner particles. The toner particles can be prepared, if desired, in finely divided form capable of forming high resolution electrographic images, and the toner particles can be used in dry or liquid developer formulation. The toner particles are heat fusible preferably at low temperatures, resist toner offset, and have good cohesivity.

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.
