53 IM-0233 TITLE POSITIVE-WORKING PHOTOSENSITIVE ELECTROSTATIC MASTER ABSTRACT OF THE DISCLOSURE High resolution photosensitive electrostatic master which forms conductive exposed image areas upon imagewise exposure comprising an electrically conductive substrate bearing a photosensitive layer consisting essentially of at least one acid labile compound which decomposes to form acid, and a photoinitiator or photoinitiating system which upon exposure generates a catalytic amount of a strong acid. A xeroprinting process from producing positive images in said photosensitive layer of the master is also disclosed. The master is useful in the graphic arts field, e.g., making color proofs, preparation of printing circuit boards, resists, solder masks, etc. 53
