Abstract (en)
[origin: EP0218160A1] A lithographic printing plate support material comprising an anodized aluminum plate having an anodic layer, a silicate layer in contact with the anodic layer, and a metal salt layer, in contact with the silicate layer, which comprises a metal salt having the formula MX wherein M is a metal selected from the group consisting of zinc, magnesium, nickel, and chromium, and X is an anion selected from the group consisting of acetate, chloride, and borate. A method for preparing the support material comprises the steps of contacting an anodized aluminum plate with a silicating agent and contacting the silicated plate with the above-described metal salt. Lithographic printing plates comprising the above-described support material and a radiation-sensitive layer exhibit improved press sensitivity and extended shelf-life.
