ABSTRACT:
UV-sensitive negative acting silver halide photographic elements are used in contacting processes, and especially dry etch correction processes and can be safely handled under white light. These elements comprise a support base, a negative acting hydrophilic colloidal silver halide emulsion layer comprising photographic silver halide grains, and one or more hydrophilic colloidal layers, wherein said silver halide emulsion support base has on its surface most distant from the layer an antihalation layer comprising a water-removable UV-absorbing compound having significant absorption in the range of from 350 to 400 nm.
