Abstract
PURPOSE:To produce a colored copper material having a film wherein initial color tone is grayish black and gradually discolored to aquamarine by applying aqueous paint consisting of aqueous resin and specified copper compd. on a copper-base metallic base material whose surface is cleaned and roughened. CONSTITUTION:The surface of a copper member such as a copper plate is previously degreased, cleaned and roughened by forming fine ruggedness on the surface by a method such as sandblasting. Then the surface of the roughened copper plate is applied with aqueous paint consisting of the mixture of aqueous resin wherein polyvinyl acetate-base resin is made hydrophilic with an emulsifying agent, basic copper sulfate or basic copper carbonate and 5-30wt.% copper oxide such as cuppric oxide by spray coating, roller coating and brushing, etc. The colored copper material as a building material having a film which is slowly discolored to aquamarine from initial tone color having deep grayish black free from metallic luster and is excellent in adhesive force is produced by forcedly drying it in a furnace e.g. at 90 deg.C.
