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.
