Embodiment 1

[0030] Refer to the attached figure 1 , A frosted holographic anti-counterfeiting paper in this embodiment includes a frosted layer 500, a transparent layer 400, a holographic anti-counterfeiting layer 300, a base material layer 200 and a fiber paper layer 100 sequentially arranged from outside to inside. The frosted layer 500 includes several Frosted particles with color, the color of the frosted particles coincides with the color of the holographic anti-counterfeiting layer 300 . In this embodiment, the color of the frosted particles is overlapped with the color of the holographic anti-counterfeiting layer 300, so that the holographic pattern will not be affected, and the anti-counterfeiting information in the holographic anti-counterfeiting layer will not be damaged, so that the holographic anti-counterfeiting paper has frosted The hand feel and the holographic anti-counterfeiting effect is guaranteed, which is more practical.

Abstract

A frosted holographic anti-counterfeiting paper of the present invention comprises a frosted layer, a transparent layer, a holographic anti-counterfeiting layer, a substrate layer and a fiber paper layer which are sequentially arranged from the outside to the inside, the frosted layer includes several colored frosted particles, the The color of the frosted particles coincides with the color of the holographic anti-counterfeiting layer. By overlapping the color of the frosted particles with the color of the holographic anti-counterfeiting layer, the holographic pattern will not be affected, and the anti-counterfeiting information in the holographic anti-counterfeiting layer will not be damaged, so that the holographic anti-counterfeiting paper has a frosted feel and ensures The holographic anti-counterfeiting effect is more practical.

Description

technical field [0001] The invention belongs to the technical field of laser anti-counterfeiting, in particular to a frosted holographic anti-counterfeiting paper and a preparation process thereof. Background technique [0002] At present, as an effective and practical anti-counterfeiting technology, hologram text is favored by people and has been developed rapidly on an unprecedented scale. Laser holography is still the mainstream technology for public anti-counterfeiting in the world so far, and its characteristics of easy identification, difficulty in imitation and easy mass production are difficult to be replaced by other anti-counterfeiting technologies in a short period of time. Holographic and anti-counterfeiting are almost regarded as such by people. It seems that holographic trademarks are anti-counterfeiting trademarks, or anti-counterfeiting trademarks are holographic trademarks. The use of laser holography for anti-counterfeiting in my country began in the 1980s...
