Abstract
The present invention provides an imaging element comprising in the order given (i) a hydrophilic grained and anodized aluminum support with an aluminum oxide barrier layer of at least 10 nm thickness, (ii) an image receiving layer containing physical development nuclei in an amount of at least 0.7 mg/m.sup.2 and (iii) a photosensitive layer containing a silver halide emulsion being in water permeable relationship with said image receiving layer. The invention also relates to a method for making lithographic plates with said imaging element.
