The optical change element layer can be formed, for example, by bonding a hologram sheet on the image receiving layer. As the hologram sheet, a relief type hologram sheet can be used. The relief hologram sheet is formed by laminating a hologram forming layer and a hologram effect layer on a support film in this order. More specifically, the hologram sheet is a resin layer that is solid at room temperature and has a thermoforming property, for example, a thermoplastic resin that is solid at room temperature, on the surface of a support film such as a polyethylene terephthalate film. A line-curable resin layer (hologram forming layer) is formed, and a hologram master on which a hologram interference pattern is formed in an uneven shape is pressed and compressed, and the uneven shape is transferred to the resin surface and cured. Furthermore, the hologram effect of a thin film made of a material (for example, a vapor-deposited film of TiO ₂ , SiO ₂ , or ZnS) having sufficient transparency and large reflectivity at a certain angle on the uneven surface and having a different refractive index from the hologram forming layer. It can be obtained by forming a layer. A hologram in which an image is reproduced by white light such as daylight or illumination light has excellent decorativeness because a hologram image is observed even in a normal state. On the other hand, a type in which an image is reproduced by a laser beam is excellent in falsification discoverability.

Further, in the present invention, a bead-containing layer having a bead according to the present invention can be provided. The light component is emphasized by interference, and the colored light having a color tone different from that of the incident light is returned in the incident light entering direction. The reflective substrate includes a reflective substrate and transparent beads arranged and arranged on the substrate.
In the bead holding layer having beads, a resin layer is provided on a reflective substrate, and a bead made of glass or the like having a diameter of 1
A large number of beads of 0 to 60 μm, preferably 15 to 40 μm are arranged and arranged, and the optical refractive index of the beads is 1.6 to
2.1 is preferred, and 1.7 to 2.0 is more preferred. Incident light that has entered from the outside travels into the beads, and at least part of the light is reflected by the reflective substrate from the transparent beads via the resin layer, returns to the beads again, and travels outward. Since the surface protruding outward from the beads is spherical, even if there is some variation in the angle of incidence, the same effect is produced, and the reflected light can be returned in the incident direction.

Next, according to the present invention, a reflective layer can be provided. The reflective layer of the present invention may be formed of at least a metal thin film, a metal oxide thin film, a light interference substance, and a light diffraction layer. Selected from. The reflective layer is preferably provided by printing a paint containing a powder capable of expressing an interference color such as an interference substance, a metal oxide, and mica in an arbitrary pattern.

Examples of the metal oxide include titanium dioxide, iron oxide, lower titanium oxide, zirconium oxide, silicon oxide, aluminum oxide, cobalt oxide, nickel oxide, cobalt titanate, and the like, and Li ₂ CoTi ₃ O ₈ or KN.
Examples thereof include composite oxides such as iTiOx and mixtures of these metal oxides, but are not particularly limited as long as they are metal oxides capable of exhibiting interference colors. As the interference substance layer, a metal film having an interference color obtained by oxidizing the surface of the metal film can be used. These metal films are prepared by a method of anodizing metal aluminum, metal titanium, stainless steel film, or the like, a method of preparing a metal oxide capable of expressing interference colors by a sol-gel method, and coating the same or a method of coating a metal capable of developing interference colors. A method of applying an alkoxide to a metal film and thermally decomposing the metal film, and a vapor deposition operation method such as CVD and PVD can be used.

In the present invention, high image durability is obtained by evaluating the hardness of the surface of the image recording medium or the upper layer on the image forming layer side by Vickers hardness and setting the Vickers hardness in the range of 2 to 150. is there. When the Vickers hardness is less than 2, the image is inferior in image durability, and the image is shaved on the card surface due to friction or the like. On the other hand, if the Vickers hardness is larger than 150, the film is too hard, causing surface cracks due to scratch burrs and deterioration of bending resistance.

Incidentally, the Vickers hardness H in the present invention,
h, h1 or h2 is defined by a value obtained as follows.

Using a triangular indenter with a diagonal angle of 80 °, equipment used: thin film hardness tester MHA-400 (manufactured by NEC Corporation) Load: 0.1 mg to 0.2 g Pushing speed: 1 to 25 nm / sec Measurement environment: 20 -30 ° C / 40-80% RH Indentation depth: Within 3 μm from the surface A diamond triangular pyramid needle is pushed in by a piezoelectric actuator. At this time, assuming that the indentation depth at the time of indentation with the load W is X, the hardness at the depth a is H (a).
W (X) = K∫H (a) (X−a) da (K: constant) If the material is a uniform material having no change in hardness, W (X) = １ ／ KHX2 Therefore, the indentation depth X The graph of the load W (X) with respect to the square of becomes a straight line, and H (Vickers hardness) can be obtained from the slope.
