ABSTRACT:
A light-sensitive composition for use in making a light-sensitive layer of, for instance, a presensitized plate from which a lithographic printing plate is to be prepared, which comprises a fluorine-containing surfactant and is characterized in that the fluorine-containing surfactant is a copolymer of (i) an acrylate or methacrylate having a fluoroaliphatic group, Rf, which has 3 to 20 carbon atoms and at least 40% by weight of fluorine atoms and at least three terminal carbon atoms of which are fully fluorinated; and (ii) a poly(oxyalkylene) (meth)acrylate and that Rf group-containing (meth)acrylate monomer unit is present in the copolymer in an amount of from 25 to 70% by weight based on the total weight of the copolymer. The composition provides a light-sensitive layer of a uniform thickness and it provides a lithographic printing plate having acceptable and excellent properties.
