ABSTRACT:
A presensitized plate for use in making a lithographic printing plate requiring no dampening water which comprises a substrate having provided thereon a primer layer, a photodimerizable photosensitive layer containing at least one organotin compound and at least one silane coupling agent in a total amount of 0.1 to 20% by weight of the photosensitive resin and a silicone rubber layer, in order, the photosensitive layer of the presensitized plate is formed by previously incorporating the above two compounds into a photosensitive resin composition and then applying the composition to the surface of the primer layer or by contacting a solution containing the compounds with the previously formed photosensitive layer and penetrating the solution into the photosensitive layer. The dry presensitized plate is extremely strong in adhesiveness between the primer layer and the photosensitive layer and exhibits a relatively broad developing latitude and a good image reproducibility.
