Embodiment 1

[0019] As shown in FIG. 1 , the scratchable laser holographic anti-counterfeiting film of the present invention contains a base film, which is composed of a PET transparent film 1 and an aluminum layer 2 bonded on one side of the PET transparent film 1 . The aluminum layer 2 is sequentially compounded with an information layer 3, a scratchable hot stamping layer 4 and a hot stamping adhesive layer 5, and the aluminum coating layer 2, information layer 3, scrapable hot stamping layer 4 and hot stamping adhesive layer 5 are bonded together together. Wherein the PET transparent film 1 is a plastic film.

[0020] Wherein, what described base film selects for use is the GD-04 type silver aluminum film produced by Fujian Xinxing Vacuum Coating Factory, and the scrapable stamping layer 4 is the YK0365 type high-speed stamping oil produced by Hunan Yakeli Nano Chemicals Co., Ltd. It is formed by coating, and the hot stamping adhesive layer 5 is formed by applying PS—530105 type hot s...

Abstract

The invention relates to a scratch type laser holographic anti-counterfeiting film and a preparation method thereof. The anti-counterfeiting film is characterized by comprising a base film consisting of a PET transparent film and an aluminized layer laminated on one side of the transparent film; an information layer, a scratch type hot-stamped layer and a hot-stamped rubber layer are sequentially arranged below the aluminized layer; and the aluminized layer, the information layer, the scratch type hot-stamped layer and the hot-stamped rubber layer are laminated together. The method for preparing the scratch type laser holographic anti-counterfeiting film comprises the following steps of: firstly, preparing the base film; secondly, forming the information layer by using photoengraving technology, developing technology, an electroforming mode, die pressing heat transfer and the like; thirdly, coating the scratch type hot-stamped layer on the information layer; and finally, coating the hot-stamped rubber layer on the scratch type hot-stamped layer to obtain the scratch type laser holographic anti-counterfeiting film. The scratch type laser holographic anti-counterfeiting film not only has a long quality guarantee period, but also is odorless, does not pollute the environment in the production process and is beneficial for the health of printing workers. The scratch type laser holographic anti-counterfeiting film can be used for covering confidential information, such as cipher codes or awards on scratch cards, prepaid phone cards, invoices and various securities.

Description

technical field [0001] The invention relates to an information covering film and a preparation method thereof. Specifically, it is a scratchable laser holographic anti-counterfeiting film and a preparation method thereof for covering confidential information such as scratch cards, telephone recharge cards, invoices and passwords or awards on various securities. Background technique [0002] As we all know, confidential information such as scratch cards, telephone recharge cards, invoices and passwords or awards on various securities are covered with a scratchable film layer. The scratch-off film layers are all screen-printed with silver ink on top of the confidential information. In the printing process, it is necessary to dilute the silver ink with chemical solvents such as isophordione. Due to the strong smell of chemical solvents such as isophordione, it will not only pollute the working environment, but also is not conducive to the health of printing workers. healthy. ...
