摘要:
A white or grayish white substance can be formed by dipping, in the first step, aluminum or an aluminum alloy having an anodically oxidized film in a first solution containing a specific salt or electrolyzing with said first solution, thereby causing the product from this salt to enter into the micropore of said film and then, in the subsequent second step, dipping the product from the first step in a second solution containing a substance which reacts with the product from the salt to be converted into a white or grayish white compound or electrolyzing with said second solution.

摘要:
A continuous electrolytic treatment apparatus for anodic oxidation and electrolytic coloring operations on an object such as a strip, wire or foil of aluminum and its alloys, wherein there are provided electric field buffer means which comprises a plurality of self-standing plates of plastic resin or the like having an electrically insulating property. The electric field buffer means are located at least in one zone in the electrolytic cell so that it can serves to effectively buffer concentration of excessive electric current to the interface between the object and the electrolytic solution at the above mentioned zone, thereby preventing burning in the surface of the object or in the oxide film formed thereon during the anodic oxidation treatment and unevenness in coloring of the object during the electrolytic coloring operation due to such current concentration, particularly when treating with a high current density.

摘要:
A photographic process for forming photographic images comprising processing a photographic element comprising a support and at least a silver halide photographic emulsion layer having image-wise distributed therein a material possessing a catalytic action with a cobalt (III) complex with a photographic processing solution containing at least a cobalt (III) complex having a coordination number of 6 in the presence of a primary aromatic amine developing agent, in which the formation of fog is prevented by contacting the photographic processing solution with one side of a fine open-cell porous diaphragm of a hydrophobic material, such as a porous Teflon film, the other side of which is in contact with an acid solution, whereby fogging components in the processing solution are removed from the processing solution into the acid solution through the porous diaphragm.
