    Notes: [Auszug] IT has not been definitely settled whether optical sensitizing involves a chemical decomposition of the dye. The observation of Lescynski1 that some twenty atoms of silver could be obtained (for a certain exposure) for one dye molecule indicated that either a ‘physical’ transfer ...
