Zusammenfassung:	PURPOSE: To provide a photosensitive planographic printing plate of high sensitivity, excellent in printing durability and chemical resistance and improved in plate inspecting property, film remaining property and removing property in the film edge part. CONSTITUTION: The photosensitive planographic printing plate is obtd. by subjecting an aluminum supporting body to electrolytic roughening treatment in an electrolytic soln. containing nitric acid and forming a photosensitive layer containing an o-quinone diazide compd., alkali-soluble resin and inclusion compd. on the supporting body. Or, the printing plate is obtd. by graining and anodically oxidizing an aluminum supporting body, treating the surface of the supporting body with a soln. of ammonium salt or metal salt of groups Ia, IIa, IIb, IVb, VIIa, VIII of carboxylic acids, and then forming a photosensitive layer containing an o-quinone diazide compd., alkali-soluble resin and inclusion compd. on the surface of the supporting body. Or, a photosensitive layer containing an inclusion compd. which includes the compd. to constitute the photosensitive layer is formed on a supporting body.
