ABSTRACT:
A photohardenable electrostatic master comprising an electrically conductive substrate; a photohardenable layer, and a conductant sealant layer, the conductant being a thiourea or a thioamide present in an amount sufficient to control the discharge characteristics of the sealant layer. The master is particularly useful in the graphic arts field, especially in the area of color proofing wherein proof are prepared to simulate the images produced by printing.
