Abstract
1,246,696. Anodizing aluminium. HAWTHORN BAKER Ltd. Jan. 23, 1970 [Jan. 29, 1969], No.4941/69. Heading C7B. [Also in Division G2] A photo-lithographic plate is prepared by anodizing an A1 sheet in a continuously circulated acid solution, e.g. of sulphuric, oxalic, phosphoric or chromic acid, containing a hydrophilic colloid, e.g. 0À1-5% of hydroxyethyl cellulose, polyacrylamide, poly (ethylene oxide) resin, polyvinyl alcohol or pyrrolidone, starch or gum arabic, and applying a photo-sensitive coating, e.g. a diazo coating (naphthol or aryl-amine) or an ester of an unsaturated acid such as polyvinyl cinnamate, to a surface of the anodized sheet on which is absorbed a monomolecular layer of the colloid. The cathode may be of steel, C, Pb sheet, or a Pb -lined bath. Prior to anodizing, the A1 sheet may be cleaned by etching in NaOH solution, then grained by sand blasting or AC electrolytic treatment in dilute HCl, and rinsed in NaOH, HNO 3 or water.
