摘要： Electrochemically grained and anodized aluminum supports are treated with a post-treatment coating solution containing a polymer derived at least in part from vinyl phosphonic acid and phosphoric acid. This post-treated support is useful as substrates in the preparation of lithographic printing plate precursors. The post-treatment substrate treatment enables wide latitude in manufacturing and compatibility with silicate-free developers to achieve negligible background staining and oxide attack.

摘要： Aluminum-containing metal sheets can be electrochemically grained to provide a center line average roughness (Ra) of less than 0.60 μm and an average maximum pit depth (Rv) of less than 4.5 μm using a current density of at least 50 A/dm2 and a charge density less than or equal to 850 coulombs/dm2. This improved metal sheet can be used as substrates for imageable elements including lithographic printing plates that exhibit reduced blanket toning.
