ABSTRACT:
Certain members of the class of odd-numbered methine arylidene dye bases are found to be of use in thermally-developable photosensitive compositions and thermally-developable photosensitive elements containing such agents. These compounds are acutance agents which are relatively stable against photo-bleaching but undergo thermochemical bleaching on heating in silver salt-containing thermally-developable photosensitive compositions.
