    摘要： A developer composition of an alkaline aqueous solution containing a reducing inorganic salt, typically an alkali metal salt of sulfurous acid such as sodium sulfite, is found to be applicable for development of a lithographic printing plate material containing a photosensitive o-quinonediazide compound and an organic polymer, with reduced deterioration in developing capacity caused by the air and enhanced stability with lapse of time. In particular, a developer composition composed of an alkaline aqueous solution of pH 11 or higher containing a water-soluble sulfurous acid salt is effective for developing both of a lithographic printing plate material having a nega-type photosensitive layer containing a photosensitive diazo compound and an organic polymer, and a lithographic printing plate material having a posi-type photosensitive layer containing an o-quinonediazide compound and an organic polymer.

    摘要： The invention provides a light-sensitive lithographic printing plate containing a light-sensitive composition which has a different degree of solubility in an exposed area of said printing plate than in an unexposed area of said printing plate when said printing plate is developed in a developing solution. This printing plate is produced by a process which comprises coating on a support a solution prepared by dissolving a light-sensitive composition containing a light-sensitive material and at least one fluorinated surfactant having Formula (I) in a quantity of between 0.005% by weight and 0.05% by weight based on the weight of said composition, in at least one solvent having (A) a solubility parameter of at least 8(cal/cm.sup.3)1/2, and (B) a boiling point within the range of from 100.degree. to 200.degree. C. Said Formula (I) is Rf-A-Y, wherein Rf is a partially or completely fluorinated hydrophobic alkyl moiety, A is a single bind or bivalent moiety and Y is a hydrophilic moiety.
