Reticulation in Gelatin Layer by Treatment with Thiocyanate Salts

Abstract

Patterns of reticulated film that caused by treatment with thiocyanate salts were observed with an interference microscope by reflected light.
The results obtained were as follows:
1) The typical pattern of reticulated film was a net-work or was a scattered leaves-like figure, depending on procedure.
2) Production of reticulation was affected by nature of photographic gelatin.
3) A cross-section of the reticulated film looked like an eaves gutter, which was very shallow.
4) The developed silver particles were aggregated on the edge of the gutter.
