Abstract:
     A pre-coated negative photosensitive plate is composed of substrate, diazotized photosensitive resin and three-component filming resin. When it is being radiated by ultraviolet ray, photochemical cross-linking reaction takes place at the position to be radiated to generate non-soluble substance and the position not radiated can be dissolved in water developing liquid. As a result, a print plate with long service life is obtained, which features high antiwear nature and ink affinity, and clear print quality.
