Abstract

The preparation of either a toned or planographic water-S less lithographic master imaged xerographically by vapor curing of the silicone abhesive film is described. The abhesive material is coated on a suitable substrate and a xerographically formed image is transferred to the surface thereof, The entire plate is then placed into a chamber containing the vapor of a crosslinking agent known to react with the active sites present in the silicone polymer. After a sufficient reaction time, the polymer is cured to the elastomeric state and if the toner employed is sufficiently soluble in the chamber vapor, toner fusing will also take place. If fused, the toner can be left on the surface and will act as the ink receptive media while the elastomeric background polymer, being abhesive, will reject ink wetting enabling the plate to function as a lithographic master for printing use.
