Abstract: According to the present invention, there is provided a laminated composite including an optical layer having a light reflectivity, and a latent image formation layer containing a liquid crystalline polymer material and provided on one of major surfaces of the optical layer, wherein the latent image formation layer includes at least one oriented portion in an orientation state and at least one non-oriented portion in a non-orientation state, and the oriented and non-oriented portions constitute a latent image which is unrecognizable by a direct visual observation and recognizable by a visual observation through a polarizing member. Also, according to the present invention, there is provided an information recording medium and a member of imparting a forgery-preventing characteristic including such a latent image formation layer.

Abstract: A monochromatic-light reproduction type hologram having a hologram recorded area provided with interference fringes that form a hologram image, the hologram image being reproducible by irradiating the hologram recorded area with monochromatic light at a given angle. A plurality of hologram images different from each other in the directionality of interference fringes are multiple-recorded in the hologram recorded area. Alternatively, the hologram recorded area is divided into a plurality of regions so that a plurality of hologram images different from each other in the directionality of interference fringes are separately recorded in the divided regions. The recorded area is successively or simultaneously irradiated with monochromatic light rays at given angles corresponding to the directionality of interference fringes of the respective hologram images, to reproduce the hologram images as a plurality of information patterns or a single information pattern.

Abstract: An intermediate transfer medium comprises a heat-resistant base sheet and provided thereon a release layer and an image-receiving adhesive layer on which an image pattern is formed by a sublimation transfer means in accordance with image data, said image-receiving adhesive layer, on which said image pattern has been formed, being transferred to a transfer substrate together with said release layer to produce an image-recorded article, wherein said image-receiving adhesive layer is comprised of a thermoplastic resin having a glass transition point of 50.degree. C. or above and a filler added to the thermoplastic resin and selected from the group consisting of an inorganic filler having a melting point of 200.degree. C. or above and an organic filler having a softening point or decomposition point of 200.degree. C. or above.
