White light handleable negative-acting silver halide photographic elements |
(57) 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.
