Abstract
A process is described for producing a presensitized lithographic printing plate by coating onto a surface-roughened aluminum plate a solution having dissolved in a solvent containing at least 10 wt % 1-methoxy-2-propanol a negative-working, light-sensitive composition which contains a light-sensitive diazo resin and a high-molecular weight compound and which is developable with an aqueous alkali developer, and drying the coated solution.
