The utility model is realized by the following technical scheme:
namely a hidden hollow aluminized pattern holographic anti-counterfeiting transfer paper, which is characterized in that the transfer paper comprises the following components in sequence from top to bottom: copper board ply, transfer glue layer, second aluminized layer, aluminium layer coating of plugging into, first aluminized layer, holographic information layer and impression transfer coating, first aluminized layer is fretwork aluminized anti-fake pattern layer, and its fretwork part is equipped with the shielding layer.
The aluminum layer connection coating is used for improving the binding force between the first aluminum plating layer and the second aluminum plating layer, and because the surface of the first aluminum plating layer is provided with the shielding layer and the aluminum oxide layer formed by oxidizing the aluminum layer after the processing of the first aluminum plating layer is finished, the binding force between the second aluminum plating layer and the first aluminum plating layer is seriously influenced. Meanwhile, the coating solves the problem of uneven surface caused by the aluminized pattern of the first aluminized layer and the shielding layer, and enhances the mirror surface effect of the second aluminized layer.
The second aluminized layer is used for shielding the first aluminized layer (the hollowed aluminized anti-counterfeiting pattern layer), the hollowed aluminized patterns are hidden between the paper layer structures, pattern information cannot be observed at ordinary times, and the anti-counterfeiting pattern information can be found only through light transmission observation of a strong light source (more than lumens 25).
