Said photoprecursors generate free amines on exposure to long Wavelength UV or visible radiation, have high solubility in organic solvents, and include photolabile 2-nitrobenZyl functional groups. Methods for the synthesis of the photo precursors are described, and the use of the said photopre cursors for the production of printing plates using both positive Working and negative Working techniques are dis cussed.engjournal article2014-06-05
