ABSTRACT:
A presensitized lithographic plate comprises a hydrophilic layer and a light-sensitive layer containing silver halide, a reducing agent, a polymerizable compound and a hydrophilic binder provided in order of a hydrophilic support wherein the silver halide, the reducing agent and the polymerizable compound are contained in lipophilic microcapsules which are dispersed in the light-sensitive layer. Another presensitized lithographic plate comprising a hydrophilic layer and a light-sensitive layer containing a photo polymerizable composition or a photo polymerizable compound provided in order on a hydrophilic support wherein the photo polymerizable composition or the photo polymerizable compound are contained in lipophilic microcapsules which are dispersed in the light-sensitive layer is also disclosed.
