Abstract:
An apparatus for providing a photochemical reaction comprising:a) a means for supplying an imagewise exposed photographic silver halide material comprising at least one silver halide emulsion layer, b) a means for supplying a photochemical delivery article consisting essentially of a nonporous substrate having disposed thereon a hydrogel containing one or more diffusible photochemicals, said nonporous substrate having a thickness of from about 75 to about 200 &mgr;m, c) a means for bringing said imagewise exposed photographic silver halide material and said photochemical delivery article into reactive association to form a web laminate so that a photochemical reaction can occur, and d) a downstream web laminate treating means that is either i) a means for removing said nonporous substrate from said photochemical delivery article in said web laminate, or ii) a means for delaminating said photochemical delivery article from said imagewise exposed photographic silver halide material, and a means for collecting said delaminated photochemical delivery article.
