摘要： PURPOSE:To obtain a minutely roughened surface and prevent contamination of an non-image part in a streak form from occurring, by setting the amounts of Fe, Si and Cu in an aluminum alloy to within respective predetermined ranges and restricting the amount of elemental Si to or below a specified value. CONSTITUTION:An aluminum alloy contains 0.05-1% of Fe, up to 0.2% of Si and up to 0.05% of Cu, the balance being A and unavoidable impurities, with the amount of elemental Si internally distributed being not more than 0.012%. If the Fe content is less than 0.05%, the effects of obtaining finer recrystallized grains and making an electrolytically roughened surface uniform and minutely roughened are slight, whereas if the Fe content is more than 1%, the electrolytically roughened surface will be nonuniform. If the Si content is more than 0.2%, the uniformity of the roughened surface is degraded, and element Si separates out to increase the possibility of contamination of non- image parts. If the Cu content exceeds 0.05%, pits 1 are enlarged in size. By restricting the amount of elemental Si to or below 0.012%, a printing plate can be obtained which hardly generates contamination of non-image parts and has extremely excellent printability.

摘要： PURPOSE:To provide an energy saving inexpensive planographic printing plate keeping the printability possessed by an aluminum printing plate and capable of printing many kinds of manuscripts with a single plate, by adhering and laminating a large number of planographic printing sheets, each of which is formed by providing a photosensitive composition layer an aluminum sheet receiving surface roughening treatment and subjected to anodic oxidation if necessary, to a carrier through an adhesive in a releasable manner. CONSTITUTION:Planographic printing sheets 5, each of which is formed by applying a photosensitive layer 4 to a surface roughened aluminum foil 3, are adhered and laminated to a plastic carrier 1 through an adhesive 2. As the carrier, paper, plastic, a metal alone or a metal composite are pref. and the aluminum foil comprises aluminum or an alloy thereof and the thickness of the aluminum foil is pref. 10-100mum based on the thickness of a single layer. After printing by the uppermost phanographic printing sheet was finished, said sheet can be simply released and printing can be performed by the use of the new planographic printing sheet after release and many kinds of manuscripts can be printed by one planographic printing plate.

摘要： PURPOSE:To provide a supporting member excellent in the strength, printability and economy by joining a surface layer material made of a highly pure Al alloy plate on a core Al alloy plate with a specified yield strength. CONSTITUTION:A surface layer material made of an Al alloy plate containing Al more than 99.5(wt), Fe less than 0.3% and other components each less than 0.15% as impurities is joined on an Al alloy plate as core material 80-500mu thick with a yield strength of more than 15kg/mm. at a thickness of 10mu, preferably 10-100mu to obtain an Al composite plate. Then, the composite plate thus formed is roughened in the surface by electrochemical sanding and then, etched chemically by alkali or the like. Additionally, it undergoes an anodic oxidation in the skin if necessary to obtain an intended supporting member.
