    Abstract: PROBLEM TO BE SOLVED: To provide an aluminum alloy plate for a lithographic printing form of which the uniformity of a rough plane due to electrolytic etching is improved so as to prevent a stripe pattern from appearing; and a method for manufacturing the same. SOLUTION: This aluminum alloy plate is composed of 0.1-0.6 wt.% Fe, 0.01-0.2 wt.% Si, 0.001-0.01 wt.% Cu, 0.01-0.08 wt.% Zn, 0.002-0.03 wt.% Ti, and the balance being Al and unavoidable impurities and contains a plurality of intermetallic compound particles in the metallic structure. The content (D) of the intermetallic compound particles with particle sizes of 0.1 μm or higher but lower than 1.0 μm and the content (E) of the particles with particle sizes of 1.0 μm or higher satisfy the relation represented by (D/E)×100≥0.20.

    Abstract: PROBLEM TO BE SOLVED: To provide an aluminum alloy substrate for a PS (Post Script) plate, improved in the evenness of a rough surface through electrolytic etching, and the manufacturing method for the same. SOLUTION: The aluminum alloy substrate for PS plate is provided with a composition consisting of Fe: 0.1-0.7 wt.%, Si: 0.01-0.2 wt.%, one kind or more than two kinks of rear earth group element of 0.005-1.0 wt% and a balance consisting of Al as well as inevitable impurities. The substrate can contain Ni: 0.005-0.1 wt.% and one kind or more than two kinds of rear earth group element: 0.005-0.3 wt.% in addition to the composition. In this case, one kind or more than two kinds among Ce, La, Nd can be selected as the rear earth elements.

    Abstract: PROBLEM TO BE SOLVED: To produce a photosensitive printing plate excellent in vacuum adhesion, having resistance to wear and pressure, free from surface stickiness in use and causing no problem on developability, etc., after long-time storage. SOLUTION: The photosensitive printing plate 1 has a substrate 2, a photosensitive layer 3 formed on the substrate 2 and mat particles 4 formed on the photosensitive layer 3. The mat particles 4 contain a copolymer containing (meth)acrylamides as constituent units and are formed by dissolving the copolymer in a solvent and applying the resulting solution on the photosensitive layer 3.
