Latest Patents
Uyama holds a patent for a transparent hologram seal, which involves a complex layering process. The patent describes a hologram forming layer, a transparent evaporated layer, a colored layer, an adhesion anchor layer, and an adhesive layer that are sequentially laminated on the under surface of a base member. This laminated body serves as a seal due to the presence of the adhesive layer. The base member is designed to have adequate rigidity, flexibility, tensile strength, and surface flatness. The hologram forming layer features a relief type hologram image, while the transparent evaporated layer consists of a multi-layered ceramic structure. This structure is constructed by alternately laminating high-refractive index layers and low-refractive index layers, with a preferred thickness of 1 µm or less. The transparent evaporated layer alters the color of visible light within a predetermined wavelength range based on the viewing angle, whether the light is transmitted through or reflected from it.
