[0002] As we all know, holographic anti-counterfeiting forms have been widely used in existing documents, but except for bank cards that use holographic anodized aluminum for positioning and use, most of them are full-page information that is not positioned and used randomly
In particular, although transparent holography has the advantage of not covering personalized information, it is more difficult to realize positioning due to small contrast and difficult identification. For example, my country's first-generation resident ID cards and current motor vehicle driver's Holographic anti-counterfeiting, but they are not positioned

The invention discloses a composite positioning transparent homographic certificate anti-counterfeiting film, and belongs to the technical field of laser homographic anti-counterfeiting material manufacturing. The film mainly comprises a positioning substrate (1), a positioning transparent homographic film (3) evenly distributed on the positioning substrate (1), a corresponding positioning cursor(4), composite glue (9) smeared on the positioning transparent homographic film (3), and an anti-adhesion layer (5) smeared on the back of the positioning substrate (1). The positioning transparent homographic film (3) consists of transparent homographic substrate (9), a die pressing information imaging layer (6) and an information layer (7), which are composed in order from below. The composite glue (9) is smeared on the surface of the information layer (7). The transparent homographic substrate (9) is composed with the positioning substrate (1) through homographic positioning peeling glue (2). The invention increases seriousness, uniqueness and unity of certificate anti-counterfeiting, and increases strength of certificate anti-counterfeiting.
Description
technical field [0001] The invention relates to a positioning composite transparent holographic certificate anti-counterfeiting film, which belongs to the technical field of manufacturing laser holographic anti-counterfeiting materials. Background technique [0002] As we all know, holographic anti-counterfeiting forms have been widely used in existing documents, but except for bank cards that are made of holographic anodized aluminum for positioning and use, most of them are full-page information without positioning and are used randomly. In particular, although transparent holography has the advantage of not covering personalized information, it is more difficult to realize positioning due to small contrast and difficult identification. For example, my country's first-generation resident ID cards and current motor vehicle driver's Holographic anti-counterfeiting, but they are not positioned. Contents of the invention [0003] The purpose of the present invention is to pr...
