ABSTRACT:
The present invention provides a presensitized plate useful for preparing a lithographic printing plate, which comprises a substrate provided thereon with a light-sensitive layer containing a fluoro-aliphatic group-containing copolymer prepared by copolymerizing at least (A) a fluoroalkyl(meth)acrylate represented by the general formula (I) and (B) a polyoxyalkylene group-containing ethylenic unsaturated monomer. By such a presensitized plate, a lithographic printing plate is provided with a light-sensitive layer whose uniformity and solubility or dispersibility in a developer are improved and which has an ability of forming high contrast images without entraining any reduction of the sensitivity.
