Abstract

See full text

A hologram forming layer, transparent evaporated layer, colored layer, adhesion anchor layer, and adhesive layer are sequentially laminated on the under surface of a base member. The laminated body is used as a seal by the presence of the adhesive layer. It is preferable for the base member to have adequate rigidity (flexibility, tensile strength) and surface flatness. The hologram forming layer has a relief type hologram image. The transparent evaporated layer is a multi-layered ceramic layer constructed by alternately laminating high-refractive index layers and low-refractive index layers and the thickness thereof is preferably set to 1 .mu.m or less. In the transparent evaporated layer, the color of visible light in predetermined wavelength range is changed according to the viewing angle when it is transmitted therethrough or reflected therefrom.
