Abstract

PURPOSE:To provide an electrodeposited surface uniformly on the entire part of an alumite-treated surface, by subjecting aluminum and an aluminum alloy to an alumite treatment, subjecting the alumite-treated surface to penetrating printing and drying, then releasing a residual ink remaining on the alumite- treated surface, and subjecting the alumite-treated surface to an electrodeposition treatment and baking. CONSTITUTION:In penetration printing, characters, patterns or the like are formed on an alumite-treated surface by using a printing ink having an excellent penetrating property, while said ink is prepared by mixing a dye into a vehicle high in consistency and rich in penetrating property, whereby a portion of the ink is permitted to penetrate into pores formed in the alumite-treated surface. The printed surface is dried, then the residual ink on the alumite-treated surface is released, and the alumite-treated surface is subjected to an electrodeposition treatment. A portion of the penetrating printing ink penetrates into the pores in the alumite-treated surface 2 provided on the outer surface of aluminum 1 to form a pattern 3, and a transparent or translucent electrodeposited surface 4 being lustrous and beautiful is provided on the entire part of the alumite- treated surface 2 including the pattern 3.

However, when a pattern or the like is formed on the alumite-treated surface by ordinary printing processing means, the pattern or the like is formed in a raised shape on the alumite-treated surface, and this pattern or the like is spread over the entire alumite-treated surface during the electrodeposition coating process. It is difficult to form the electrodeposited coating on the areas where the pattern is formed, and the electrocoated coating cannot be uniformly applied to the alumite-treated surface over the entire surface. , as a result of an experiment. -However, as a result of continuing research into forming a uniform electrodeposition coating surface over the entire surface of the alumite-treated surface, the inventor of the present invention discovered that the alumite-treated surface When a pattern or the like is printed on the treated surface, a penetrating printing ink is used to permeate the printing ink into the bores formed on the alumite treated surface, and then residual ink remains on the surface of the alumite treated surface. It was discovered that by peeling off the alumite and then performing the electrodeposition coating treatment, the electrodeposition coating treatment surface could be uniformly formed over the entire surface of the alumite treatment surface, and this led to the completion of the present invention.
