Abstract

PURPOSE: To obtain a sharp image-forming Al plate by coating the anodic oxidized surface of an Al plate with a substance which is activated with energy radiated, and then radiating light, etc. to carry out sealing without using a mask.
CONSTITUTION: The anodic oxidized surface of an Al plate is coated with or dipped in an inorg. or org. cpd. of an acidic soln. of a water sol., more than divalent metal salt which is activated with energy such as light radiated, or a complex such as an org. acid salt of a more than divalent metal. This Al plate is then put in vessel 3 filled with sealing agent 4 such as (NH4)2Cr2O7, and irradiated with light from high voltage mercury lamp 5, etc. to allow the coated cpd. to be adsorbed on current flowing pores present in the anodic oxide film, thus inactivating the plate, In order to carry out partial sealing, a suitably perforated screen is closely contacted to Al plate 1. By this treatment a sharp image can be formed on the Al plate.
