ABSTRACT:
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.
