| titleOfInvention | Process for making lithographic printing plate |
| abstract | Process for making a lithographic printing plate having an oleophilic amplified image prepared by n (a) providing a silicated aluminum substrate with a hydrophilic, anionic, negatively charged surface and a layer on said surface of a light sensitive, cationic, positively charged, water soluble diazonium material having at least two reactive sites per molecule, each reactive site being capable of being chemically altered by actinic light or chemically reacted with an anionic material; n (b) selectively and incompletely exposing the diazo layer to actinic light to alter only a portion of the reactive sites thereby adhering the diazo material to the substrate in the exposed areas; n (c) coupling the diazo layer with an anionic material to reinforce diazo in the exposed areas in situ and remove diazo from the unexposed areas by contacting the substrate after exposure with an anionic material in water in a quantity and for a time sufficient to couple the anionic material with the diazo and dissolve the coupled product from the unexposed areas; and n (d) rinsing with water to provide a printing plate having a reinforced, oleophilic image and a clean, hydrophilic background. |
