Abstract
PURPOSE:To effectively carry out reduction, erasion, or correction of a base metal image obtained by intensifying a silver image with a base metal, such as Ni or Co, by bringing the image in contact to an aqueous solution of a specified oxidant. CONSTITUTION:The bleaching solution of a base metal image to be used consists of a ferric compound, such as a ferric chelate of a ethylenediamine tetraacetic acid; a cerium (IV) compound, such as cerium (IV) sulfate; a cupric compound, such as cupric sulfate; a chromium (VI) compound, such as chromium (VI) oxide; or an aqueous solution containing nitric acid. A preferable content of the above oxidant is e.g. 10-400g of ethylenediamine tetraacetic acid ferric chelate per liter, or 20-300g of cerium (IV) compound per liter. When this method is applied to a base metal dot image, it permits the dot image to be reduced in size without impairing the image form and without forming a fringe around the dot image.
