Abstract
The utility model relates to the technical field of laser holographic anti-counterfeiting, in particular to a laser holographic anti-counterfeiting hot stamping film. The laser holographic anti-counterfeiting hot stamping film comprises a plastic carrier film layer, a separation layer, an imaging layer, a medium layer and a hot melt adhesive layer which are superposed from top to bottom in turn, wherein a heat-resistant layer is arranged between the separation layer and the imaging layer. The heat-resistant layer can effectively prevent the imaging layer from losing holographic information in a high-temperature process. The laser holographic anti-counterfeiting hot stamping film can adapt to processes of secondary hot stamping, plastic enveloping, laser printing, labeling, code spraying and the like which require heating, successfully solves the problem that the common holographic anti-counterfeiting hot stamping film cannot adapt to secondary hot processing, and can be applied to random plate stamping, special plate stamping and positioning stamping.
Description
Technical field
The utility model relates to the antiforge laser holographic technical field, is specifically related to a kind of antiforge laser holographic blocking film.
Background technology
In the prior art, along with the continuous development of holographic security technology, the antiforge laser holographic blocking film is widely used in a plurality of fields by people.For example be applied in the anti-counterfeiting technology of anti-counterfeit package and card card.
In the anti-counterfeiting technology of anti-counterfeit package and card card, the antiforge laser holographic blocking film mainly is the anti-counterfeiting power that is used for improving product, and strengthens the visual effect of product appearance.In order to make that product is attractive in appearance and be difficult to forge that the antiforge laser holographic blocking film will pass through a plurality of manufacturing procedures, wherein just comprises hot procedure.As the secondary thermoprint, cross mould, technology that laser printing, decals, coding etc. need heating.In the manufacturing process of various card cards, after the thermoprint of antiforge laser holographic blocking film gone up to card card, print through laser printer and go up Word message, and the laser printer internal temperature is higher, generally can reach 200 ℃.
As shown in Figure 1, traditional antiforge laser holographic blocking film can be made up of five layers of different material layer usually, comprising from top to bottom that stack successively is provided with plastic carrier film 1, separating layer 2, information recording layer 4, dielectric layer 5 and glue line 6.China utility model patent CN201320876Y discloses a kind of reversible temperature induced color changing type holographic false proof blocking film, and this reversible temperature induced color changing type holographic false proof blocking film comprises that from top to bottom plastic carrier thin layer, separating layer, imaging layer, aluminium coated, temperature that stack successively is provided with become coating and hot melt adhesive layer.Wherein, imaging layer is one deck thermoplastic macromolecule resin, its glass transition temperature is lower, usually can only tolerate the temperature about 150 ℃, exceed said temperature, information recording layer then can softening transform, thereby cause the holographic information loss, make originally thicken unclear, glossiness of clear, dazzling hologram pattern reduce, and with sending out a mist, foaming, even the phenomenon of peeling.So just cause the antiforge laser holographic blocking film to combine with product perfect, limited the scope of application of antiforge laser holographic blocking film, the anti-counterfeiting power and the aesthetic that have hindered product reach a new height.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of antiforge laser holographic blocking film that better heat-resisting is arranged, applied range of the present utility model, and anti-counterfeiting power height, good visual effect.
The purpose of this utility model realizes by following scheme: a kind of antiforge laser holographic blocking film, comprise the plastic carrier thin layer, separating layer, imaging layer, dielectric layer and the hot melt adhesive layer that superpose and be provided with successively from top to bottom, it is characterized in that: between described separating layer and described imaging layer, be provided with heat resistant layer.
Described heat resistant layer is an acrylic compounds heat cure cross-linking type nanometer composite layer.
The thickness of described heat resistant layer is 0.3-0.7 μ m.
The thickness of described heat resistant layer is 0.5 μ m.
Advantage of the present utility model is: in the utility model, added heat resistant layer between separating layer and the imaging layer, heat resistant layer can effectively protect imaging layer not lose holographic information under high-temperature technology.The utility model can adapt to the secondary thermoprint, cross mould, technology that needs such as laser printing, decals, coding heat, successfully solved the hot worked difficult problem of common holographic false proof blocking film incompatibility secondary.The utility model can be applied to that disorderly version is scalded, special edition scalds and scald the location.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, a kind of antiforge laser holographic blocking film comprises from top to bottom plastic carrier thin layer 1, separating layer 2, imaging layer 4, dielectric layer 5 and hot melt adhesive layer 6 that stack successively is provided with, is provided with heat resistant layer 3 between separating layer 2 and imaging layer 4.
Wherein, plastic carrier thin layer 1 is generally the PET plastic sheeting, and thickness is generally 15 μ m or 19 μ m.Separating layer 2 adopts the polyolefin resin material, and its thickness almost can be ignored.Heat resistant layer 3 is made of a kind of material with thermal resistance effect of the prior art, heat resistant layer 3 can be acrylic compounds heat cure cross-linking type nanometer composite layer, acrylic compounds heat cure cross-linking type nano composite material is a kind of known thermal resistance material, its coating thickness is 0.3-0.7 μ m, and preferred coating thickness is 0.5 μ m.Imaging layer 4 adopts contour forging technology that the hologram pattern mold pressing is obtained imaging layer 4 because of having different requirements different to color, surface abrasion resistance and chemical resistance usually, and its thickness is 0.5 μ m.Under the vacuum state, dielectric layer 5 is plated on the surface of imaging layer 4, thickness is the 250-400 dust.Glue line 6 is made of PUR.
During preparation the utility model, earlier separating layer 2 is coated on the plastic carrier thin layer 1; On separating layer 2, be coated with heat resistant layer 3, imaging layer 4 more successively; The plastic film layers 1 that will scribble separating layer 2, heat resistant layer 3 and imaging layer 4 is then delivered to and is carried out mold pressing on the moulding press, and the hologram case obtains imaging layer 4 on imaging layer 4; Next step is exactly a plating medium formation dielectric layer 5 on imaging layer 4, during the plating medium, can select opaque medium-aluminium according to product requirement, or transparent medium-silica, zinc sulphide, magnesium fluoride etc., as the local transparent effect of need, can as required aluminium coated be made the picture and text of hollow out or the aluminium lamination of net-point shape, can make the utility model become transparent like this, and hologram image still see too clearly; Coating one deck PUR forms hot melt adhesive layer 6 on dielectric layer 5 at last, can obtain having stable on heating antiforge laser holographic blocking film.
Above content is the specific embodiment of the present utility model; protection domain of the present utility model just only is not confined to this; for those skilled in the art, any equivalents that needn't just can expect through creative work all belong to protection domain of the present utility model.
