METHOD FOR MANUFACTURE OF NEGATIVE WASHING-OFF RELIEF IMAGE AND ELEMENT USED FOR IT

摘要

PURPOSE: To provide a method which is environmentally safe, extremely simple and efficient. CONSTITUTION: This method consists successively of (a) a stage for applying a non-photosensitive and water processable layer consisting a dispersed material of solvent adherable particles in a polymer matrix, (b) a stage for applying ink imagewise to this non-photosensitive layer, to adhere the particles and forming a water-insoluble polymer blend between the particles in the inked parts and the polymer matrix and (c) a stage for removing the non-inked parts of the non-photosensitive layer, by washing the layer with an aq. developer soln.
