Abstract
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.
