To provide an article for which a forgery preventing means is taken for making a forgery more difficult, by forming peculiar information of characters, figures or the like from above a transparent base, in regard to the article such as securities or a package whereon a laminate (label or the like) having a surface formed of the transparent base and being the laminate of a diffraction pattern of a relief hologram or the like, a reflective thin film layer and an adhesive layer or a sticking layer is stuck, and a manufacturing method thereof.
A sticking object 10 is provided with a preprint part 22 formed of special ink, while in the reflective thin film layer 14, peculiar information data 14a comprising characters, figures or the like are formed in the shape of a window by making the reflective thin film layer 14 nonexistent selectively, and a part of the preprint part 22 is made visible through the portion shaped like the window. The article 1 for which the forgery preventing means is taken in this way is manufactured by the method wherein the reflective thin film layer 14 is melted by irradiation of a laser beam R so as to obtain the peculiar information data 14a.
