ABSTRACT:
An alkaline developing solution for development of a presensitized plate for use in making a lithographic printing plate, which developing solution comprises a polyoxyalkylene adduct of alkylene diamine, a polyoxyalkylene compound having an acid radical, and an anionic surfactant; a method for making a lithographic printing plate comprising the steps of: light-exposing a presensitized plate for use in making a lithographic printing plate; and developing the light-exposed plate with an alkaline developing solution comprising a polyoxyalkylene adduct of alkylene diamine, a polyoxyalkylene compound having an acid radical, and an anionic surfactant.
