摘要： An aluminum alloy, a lithographic printing plate support, a lithographic printing plate using the aluminum alloy are disclosed. The aluminum alloy is comprised of aluminum containing 0.20 to 1.0% Fe and 0.005 to 0.1% of elements selected from the group consisting of Sn, In, Ga and Zn. The support composed by the aluminum alloy can be chemically etched with an acid and/or an alkali solution and after undergoing etching the surface of the support is uniformly etched. The uniformly etched surface may be provided with a subbing layer or an anode oxidation film. The support is coated with a light-sensitive layer and utilized as a lithographic printing plate.

摘要： A lithographic printing plate support and a process for producing it are disclosed. The plate is produced by providing an aluminum alloy material which is comprised of 0.20 to 1.0% Fe, 0.005 to 0.1% of an element selected from the group consisting of Sn, In, Ga and Zn and the remainder being aluminum. The alloy may further contain 0.1 to 2% Cu. After providing the aluminum material either or both of its surfaces are subjected to a chemical etching treatment in order to provide a uniform and dense grain structure on the surface forming primary pits in the surface having a particularly defined average size. The surface is then subjected to electrochemical etching treatment in an acidic electrolytic solution in order to provide secondary pits on the surface also having a particularly defined average size. The support base may be further treated to provide in additional coating thereon or directly coated with a light-sensitive layer in order to provide a light-sensitive lithographic printing plate. By providing the particular alloy material and subjecting it to the disclosed treatment the light-sensitive layer has good adhesion with respect to the support.
