    摘要： A hologram containing information recorded such a manner that it is difficult to read. A Lippmann hologram (10) contains photoelectrically readable information (13) recorded so as to be reconstructible only with a specific invisible wavelength (6) in the infrared or ultraviolet region. It is difficult to read the information recorded on the hologram unless information about the wavelength of diffracted light (14) for reconstruction is given. The hologram is also difficult to forge and hence suitable for security purposes.

    摘要翻译： 包含以难以读取的方式记录的信息的全息图。 Lippmann全息图（10）包含记录的光电读取信息（13），以便仅在红外或紫外区域中具有特定的不可见波长（6）才可重构。 除非有关用于重建的衍射光（14）的波长的信息被给出，否则难以读取记录在全息图上的信息。 全息图也难以锻造，因此适合于安全目的。

    摘要： A method wherein a hologram is transferred from a transfer foil formed with a fine dimple pattern and having a reflecting layer, and information, e.g., an image or a character, other than information originally recorded on the hologram is added to the transferred hologram. The method comprises preparing a transfer foil having a reflection relief hologram comprising a resin layer having a fine dimple pattern, e.g., a relief hologram, a relief diffraction grating, etc., formed on the surface thereof, and a reflecting layer formed on the dimpled surface of the resin layer, transferring at least a part of the hologram to the surface of an object, and heating a part of the transferred portion with a heating device, thereby destroying the reflecting layer to record another information. Also disclosed are a method which enables a fine hologram pattern to be readily transferred to a large area, a transfer foil having a reflecting layer which enables a fine dimple pattern to be transferred precisely with excellent foil breaking characteristics, and a method of producing such a fine dimple pattern transfer foil.
