Abstract

The utility model discloses a printing coloring hologram gilding foil, which comprises a plastic basal bottom, a separation layer, an imaging layer, a hologram chart, an aluminum plating layer and a hot glue melting layer. An ink layer is printed on the imaging layer; a layer of imaging layer is applied to the ink layer; the ink layer is clamped between two imaging layers. In the utility model, the imaging layer changes from one layer into a ''sandwich'' structure, i.e. a layer of colored ink layer is clamped between the imaging layers. Because the plastic basal bottom, the separation layer and the imaging layer are transparent and the aluminum plating layer has strong reflection effect, the color of the ink can be reflected by the aluminum plating layer, so that the observer can see the colors presented by the hologram chart.

Description

The printing color Holographic hot stamping foil

Technical field

The utility model belongs to the antiforge laser holographic technology, is specifically related to a kind of printing color Holographic hot stamping foil.

Background technology

China has begun the development of laser embossed holography technology from the eighties mid-term (about 1987).Because laser holographic mark can not utilize common photograph and method of printing to duplicate simply; And along with the appearance of embossed holographic technology, make the low-cost hologram of making in enormous quantities be achieved, so laser embossed holography figure is very fast has obtained application aspect anti-tamper security.

Over past ten years, the antiforge laser holographic technology combines with traditional printing technology, produced novel anti-counterfeiting packing material, obtained successful application at packaging industry, occurred the false proof new technology that combines together with packing-holography packing and holographic printing, increase the technology content of packaging product, promoted traditional packages printing already to upgrade, become a new growth engines of packages printing industry.

After holographic packing and holographic printing occur, chosen by cigarette package press immediately, become the image that promotes cigarette package, the important techniques means that improve the cigarette package grade.Current, realize that the holographic main technique that combines with packages printing is holographic thermoprinted.The hologram of thermoprint on cigarette packing box is extremely thin, merge with packing box, can not remove, can not tear it down from cigarette case in other words intactly, in cigarette product package anti-counterfeiting, obtained widely using, and also just popularization in article such as medicine, marketable securities false proof.

Though laser holographic thermoprinted paper tinsel is very thin, structure is quite complicated, is made up of carrier thin film, separating layer, imaging layer, aluminium coated and hot melt adhesive layer usually, and wherein carrier thin film, separating layer, imaging layer all are transparent.

Now, the most frequently used laser holographic thermoprinted paper tinsel is a silver color, and in fact this is exactly the color of aluminium coated.Expect the Holographic hot stamping foil of other colors, common way is to apply dyestuff in imaging layer, is about to the needed color of imaging layer material furnishing.This method is not dark in color, and dyestuff shared ratio in imaging layer material is feasible when little.But color if desired is darker, and during shared large percentage, the performance of imaging layer material can change a lot dyestuff in imaging layer material, and this will seriously influence the contour forging implementation of processes.

Summary of the invention

The purpose of this utility model is to provide a kind of novel printing color Holographic hot stamping foil, and it can make required shades of colour, and the performance of imaging layer material big variation can not take place, and is less to the contour forging technogenic influence.

For realizing above-mentioned utility model purpose, a kind of printing color Holographic hot stamping foil, comprise plastic-substrates, separating layer, imaging layer, hologram, aluminium coated and hot melt adhesive layer successively, it is characterized in that: described imaging layer is printed with ink lay, be coated with one deck imaging layer on ink lay again, ink lay is clipped between two imaging layers.

The imaging layer of the utility model printing color Holographic hot stamping foil has become " sandwich " sandwich by original one deck, promptly in the imaging layer therebetween the painted ink lay of one deck.Because plastic-substrates, separating layer, imaging layer all are transparent, and aluminium coated has very strong reflex, therefore, just by the aluminium coated reflection, the hologram that the observer is seen presents color of ink to color of ink.

Description of drawings

Fig. 1 is the structural representation of existing laser holographic thermoprinted paper tinsel;

Fig. 2 is the utility model printing color Holographic hot stamping foil structural representation.

The specific embodiment

As shown in Figure 1, existing laser holographic thermoprinted paper tinsel can be made up of five layers of different material usually.Plastic-substrates 1 is wherein arranged, separating layer 2, imaging layer 3 is stamped in hologram 4 on the imaging layer with mould pressing process, aluminium coated 5, hot melt adhesive layer 6.

The structure of the utility model printing color Holographic hot stamping foil as shown in Figure 2, wherein plastic-substrates 7, separating layer 8, imaging layer 9 is the same with Holographic hot stamping foil shown in Figure 1, just at the surface printing of imaging layer 9 the painted ink lay 10 of one deck.And then coating one deck imaging layer 11, with mould pressing process holographic Figure 12 is stamped on the imaging layer 11.Thereafter aluminium coated 13, hot melt adhesive the layer 14 also Holographic hot stamping foil with shown in Figure 1 are the same.

In " sandwich " sandwich of the imaging layer of this Holographic hot stamping foil, painted ink lay is clipped in the middle of the imaging layer, and the border that imaging layer is combined with aluminium coated and separating layer can not be subjected to the influence of ink lay.

Claims

1. printing color Holographic hot stamping foil, comprise plastic-substrates (7), separating layer (8), imaging layer (9), hologram (12), aluminium coated (13) and hot melt adhesive layer (14) successively, it is characterized in that: be printed with ink lay (10) on the described imaging layer (9), be coated with one deck imaging layer (11) on ink lay (10) again, ink lay (10) is clipped between two imaging layers (9,11).
