PCT No. PCT/NL90/00179 Sec. 371 Date Jun. 24, 1991 Sec. 102(e) Date Jun. 24, 1991 PCT Filed Nov. 29, 1990 PCT Pub. No. WO91/08524 PCT Pub. Date Jun. 13, 1991.Method for producing a material embodying an interference pattern, in which there is solvent-coated a transparent, thermoformable lacquer on one side of a base film, which lacquer is capable of forming a releasable direct bond with the base film. The lacquer is dried so as to form a solid lacquer layer. An interference pattern is formed by embossing the side of the solid lacquer layer which faces away from the base film with a printing device carrying the negative of the interference pattern. The embossed side of the lacquer layer is clad with a metal layer. A substrate is glued onto the metal layer, and the base film is released from the lacquer layer. A second base film is provided with a second transparent lacquer layer, and an interference pattern is introduced in this second lacquer layer. Then the second lacquer layer is applied by means of a transparent glue onto the first lacquer layer, and the second base film is removed.
