PROBLEM TO BE SOLVED: To obtain new decorative effects in a decorative material used in a game machine such as a pinball machine or a slot machine. SOLUTION: This decorative material 5 is produced by three-dimensionally molding a material film 3 prepared by laminating shape-retaining synthetic resin films 2 to a multilayered membrane film 1, which is built by laminating thin synthetic resin membranes through a bonding layer and functions as a light coherent multilayered membrane. The multilayered membrane film 1 becomes uniform as a whole due to the distortion developed at its three-dimensional molding, resulting in changing the transmitting or reflecting wavelength regions in respective portions of the decorative material 5 so that various optical changes such as the revealment of iridescent interference fringes, intensified reflection or near transparentization at a certain wavelength region appear as a whole. Thus, new decorative effects, which can not be realized by the conventional coloring technique, are obtained. COPYRIGHT: (C)2005,JPO&NCIPI
