ABSTRACT:
The present invention provides a method for making a lithographic printing plate according to the silver salt diffusion transfer process using a photographic material comprising on a support a silver halide emulsion layer and a layer containing physical development nuclei comprising the steps of:
image-wise exposing said photographic material and
developing a thus obtained image-wise exposed photographic material by guiding said image-wise exposed photographic material through an alkaline processing liquid in 15 s or less; characterized in that said alkaline processing liquid comprises a hydrophobizing compound having a mercapto group that has a pK.sub.a of 4.5 or less.
