Abstract: A dark-colored, wave-length selective oxide film on aluminum is prepared thereby that the metal subsequent to a cleaning treatment is submerged into a bath consisting of an aqueous solution having pH 8.9-10.9 and at a temperature of from 20.degree. to 100.degree. C. under conditions which result in an electrode potential of between -1.1 and -0.6 volt relative to a saturated calomel electrode. The said potential can advantageously be maintained by either addition of H.sub.2 O.sub.2 to the bath or by electric polarization. In a more specific embodiment of the process there is used an aqueous solution of 1-100 g NH.sub.4 Cl or (NH.sub.4).sub.2 SO.sub.4 per liter solution with or without addition of aluminate ions AlO.sub.2 -- or Ca.sup.++, the pH of the solution, if necessary, being adjusted to pH 9 by addition of NH.sub.3, NaOH, KOH, Ca(OH).sub.2 and that the content of silicon, chromium and phosphorus each is maintained under 10 ppm.

Abstract: A process for the production of a laminate which comprises laminating a boehmite- or pseudoboehmite-treated aluminum foil with an oxidation-treated polyolefin film with the treated surface of the foil facing to the treated surface of the film under heat and pressure without the use of binders for lamination. In one embodiment, the laminate so produced may be laminated with the same laminate with the treated surface of the foil of the former facing to the treated surface of the film of the latter, under heat and pressure, or it may be laminated on the aluminum foil side with a resin film, such as a polyester or polyamide film, with the use of a binder between the aluminum foil and the resin film.

Abstract: To provide a substrate of aluminum with a dark surface layer of high absorption/emission ratio for luminous energy, the degreased and pickled substrate is immersed in a hot chromating bath until an oxide coating of not more than 2.5.mu. thickness is formed thereon. This coating is then colored black in a hot, acidic dyeing solution (pH between about 0.5 and 5) of potassium permanganate and a nitrate of cobalt or copper.
