ABSTRACT:
The invention provides a light-sensitive material for making lithographic printing plate through high-intensity short-time exposure which comprises a support and, provided thereon, at least a silver halide emulsion layer and a physical development nuclei layer wherein an intermediate layer comprising a water-permeable film forming polymer is provided between the emulsion layer and the nuclei layer. Furthermore, a process for making a lithographic printing plate from said light-sensitive material is provided which comprises subjecting the light-sensitive material to imagewise exposure of high intensity short time, silver complex diffusion transfer development and subsequently treatment with an oxidizing agent for silver and an oleophilic organic compound.
