ABSTRACT:
A positive working photosensitive lithographic printing plate comprising an aluminum substrate and a positive working photosensitive layer, the aluminum substrate having been anodized and rendered water-wettable, wherein an intermediate layer containing a polymer comprising (A) a unit interacting with an alumina layer and (B) a unit interacting with a water-wettable layer is provided between the aluminum substrate and the photosensitive layer. The photosensitive layer and the water-wettable aluminum substrate have good adhesion so that the printing plate has a satisfactory press life.
