ABSTRACT:
A light-sensitive lithographic printing plate comprising a support having on at least one surface thereof a light-sensitive layer, said light-sensitive layer exhibiting a higher oleophilicity (high affinity to grease) at the outermost surface thereof than in the balance of the light-sensitive layer. This light-sensitive lithographic printing plate is capable of beginning the printing operation with a relatively small number of spoilages and exhibits not only excellent press life but also high developability and excellent storage stability.
