    • PROBLEM TO BE SOLVED: To solve the following problems: in a technology to prevent forgery only by forming in a medium a latent image, which can be viewed through a planer polarizing plate, it is probably possible to imitate the medium itself including the latent image, then, in the situation where the polarizing plate can be easily obtained, the elaborate forgery can be relatively easily manufactured. SOLUTION: The forgery preventing medium includes a pattern which is formed in an area of parallel shade lines adjacent to one another, repeated with a prescribed width (w) and a prescribed pitch (p) on a reflection layer, the pattern is configured to form n-latent images. Each of the latent images includes a latent image 1 formed of a pattern 1 in one area 1 and a pattern in an area repeated from the area 1 at a pitch (np), a latent image 2 formed of a pattern 2 in an area adjacent to the one area 1 and a pattern in an area repeated from the area 2 at the pitch (np) and a latent image 3 formed of a pattern 3 in an area 3 adjacent to the area 2, and a pattern in an area repeated from the area 3 at the pitch (np). The forgery preventing medium includes n-latent images repeatedly formed in the same manner. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:为了解决以下问题:在仅通过在介质中形成可以通过平面偏振片观察的潜像的防止伪造的技术中,可能有可能模仿介质本身,包括 潜像,则在容易获得偏光板的情况下,可以相对容易地制造精细的伪造品。 解决方案:防伪介质包括形成在彼此相邻的平行阴影线的区域中的图案,在反射层上以规定的宽度(w)和规定的间距(p)重复,图案是 被配置为形成n潜像。 每个潜像包括由一个区域1中的图案1形成的潜像1和以间距(np)从区域1重复的区域中的图案,在相邻区域中由图案2形成的潜像2 在区域1和从区域2以间距(np)重复的区域中的图案和由与区域2相邻的区域3中的图案3形成的潜像3,以及从区域2重复的区域中的图案 间距(np)的区域3。 防伪介质包括以相同方式重复形成的n个潜像。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a machine-readable anti-counterfeit printed matter which prevents information from being easily read from a printed code mark or the like with visible light or infrared light and which makes it attainable to easily and surely perform operation for determining authenticity.SOLUTION: In the anti-counterfeit medium, a reflection layer whose reflection wavelength changes according to an observation angle is covered with an infrared transmissive shielding layer on base material. The anti-counterfeit medium has an embossed part obtained by embossing a part of the layered portion of the base material and the reflection layer, wherein the reflection layer is a cholesteric liquid crystal layer, and a wavelength of reflected light is an infrared region.
    • 要解决的问题:提供一种机器可读的防伪印刷品,其防止信息从可印刷的代码标记等容易地从可见光或红外光中读取,并且使得可以容易且可靠地执行用于确定的操作 真伪。解决方案:在防伪介质中,反射波长根据观察角度而变化的反射层被基材上的红外透射屏蔽层覆盖。 防伪介质具有通过对基材的层叠部分的一部分和反射层进行压花而获得的压花部分,其中反射层是胆甾醇型液晶层,反射光的波长是红外区域。
