A process of producing an aluminum beverage can body having a decorative surface exhibiting a dichroic effect when observed in white light. In the process, a can body is formed from a sheet of metal selected from aluminum and aluminum alloy by drawing and ironing, surfaces of the can body are cleaned to produce a cleaned can body, a decorative structure exhibiting a dichroic effect is applied to a surface of the cleaned can body, and the can body is subjected to finishing operations. The decorative structure is applied by the steps of: applying a layer of dielectric material directly onto the metal of the cleaned can body without pre-treatment of the metal with a metal brightener, and forming a semi-transparent metal layer on or within the dielectric layer. |
