ABSTRACT:
There is disclosed a process for making a lithographic printing plate having physical development nuclei between an aluminum support and a silver halide emulsion layer to which, after exposure, a treatment using at least a developing solution, a washing solution and a finishing solution is applied in this order,
the improvement wherein at least one of the above processing solutions contains at least one compound selected from the groups (A) and (B) mentioned below:
(A) at least one compound selected from the group consisting of an amine compound having a propyleneoxy group and an ethyleneoxy group, an aliphatic acid amide compound having a propyleneoxy group and an ethyleneoxy group, and a quaternary ammonium compound having a propyleneoxy group and an ethyleneoxy group; and
(B) at least one compound selected from the group consisting of urea and a derivative thereof.
