Abstract
A photosensitive silver halide element comprising a support carrying photosensitive silver halide grains in a predetermined spaced array is prepared by a method which comprises at least partially coalescing fine-grain silver halide in a plurality of spaced depressions in a hydrophobic layer, superposing said layer with a hydrophilic layer during or subsequent to said coalescence, and then separating said hydrophilic layer and said hydrophobic layer whereby said coalesced silver halide grains are retained on said hydrophilic layer in a pattern corresponding substantially to the pattern of said spaced depressions.
