The specific structure is that the paper core penetration type anti-counterfeiting paper comprises a paper core layer and a paper surface layer, wherein the paper surface layer is bonded on the upper surface or the lower surface of the paper core layer, and the specific structure is shown in figure 1; and when the paper surface layer is a layer, the paper surface layer is a semitransparent pulp paper layer.
The other specific structure is that the paper core penetration type anti-counterfeiting paper comprises a paper core layer and two paper surface layers, wherein the two paper surface layers are respectively bonded on the upper surface and the lower surface of the paper core layer, and the specific structure is shown in figure 2; when the paper surface layer is two layers, the paper surface layer can be designed to be a semitransparent pulp paper layer, the other layer is an opaque pulp paper layer, the two layers can also be designed to be semitransparent pulp paper layers, and the paper surface layer can be adjusted according to actual needs.
Wherein the paper core layer 100 has a thickness of 60-250g/m2And the ink absorption is not less than 10g/m2The paper core layer is usually prepared from pulp formed by hardwood and softwood according to a certain proportion, and has a non-transparent shape due to the thick thickness. Wherein the paper surface layer 200 has a thickness of 9-90g/m2And the paper surface layer that is the translucent form of pure color, this paper surface layer usually by white paper pulp or the paper pulp of single colour preparation, generally adopt light-colored paper pulp, its transparency degree accessible adjusts through the thickness and the paper pulp composition proportion on adjustment paper surface layer, this technique is the conventional technical scheme in this field, no longer gives details in this application.
The anti-counterfeiting mark 300 which penetrates through the upper surface and the lower surface of the paper core layer is arranged on the paper core layer 100 and is formed by image-text information formed by penetrating type printing ink on the whole area or partial area of the paper core layer. The permeable ink is different from common conventional ink, and can be applied to the paper core layer with a certain ink absorption amount, so that the permeable ink can downwards permeate to the lower surface of the paper core layer from the upper surface of the paper core layer, and the whole penetration of the anti-counterfeiting mark on the longitudinal section of the printing part of the paper core layer is realized. The penetrating ink mainly comprises the following components in percentage by mass of the total mass of the penetrating ink: 0.0002-40% of thickening agent, 0.0001-30% of identifiable material, 0.001-20% of penetrating agent and 10-90% of solvent, wherein the thickening agent is at least one of sodium cellulose, xanthan gum, polyvinyl alcohol, polyamide resin and acrylic resin; the identifiable material is at least one of dye, pigment, fluorescent material, temperature change material, wet change material and conductive material, and can also be invisible substances which can be identified by other instruments, and the identifiable material can be selected according to different environments and fields in which the anti-counterfeiting paper is applied; the penetrating agent is at least one of penetrating agent JFC, penetrating agent AEP, penetrating agent HA and penetrating agent OE, and the penetrating agent HAs the main function of assisting ink to well penetrate the paper core layer; the solvent is at least one of water, alcohols, ethers and ester solvents.
The paper core penetration type anti-counterfeiting paper is prepared according to one of the following two processes:
the preparation process comprises the following steps: the preparation method mainly comprises the steps that in the papermaking process, penetrating printing ink is adopted on a paper pulp layer with the moisture content of 70-95 wt.% to perform anti-counterfeiting image-text information manufacturing on a local part or a full plate in a spraying or printing mode to form a paper core layer, wherein the penetrating printing ink can penetrate through the paper core layer from top to bottom, and the paper core layer and the paper pulp used for preparing the paper surface layer are dried and post-treated after being compounded on a single side or double sides to obtain the paper core penetrating anti-counterfeiting paper. When the anti-counterfeiting image-text information is formed on the paper core layer, only a spraying or printing device is needed to be added on the paper making equipment, wherein the spraying or printing device can be a conventional full-page spraying or printing device, and can also be a local spraying or printing device with specific images and texts, and can be set according to anti-counterfeiting information required by customers.
And the second preparation process comprises the following steps: the preparation method mainly comprises the steps of carrying out local or full-page printing on finished paper serving as a paper core layer by adopting permeable ink, penetrating the permeable ink from top to bottom to penetrate through the paper core layer of the finished paper, and laminating and compounding the paper core layer and surface paper to obtain the paper core permeable anti-counterfeiting paper.
The following comparative examples carry out the preparation of anti-counterfeiting paper by using conventional anti-counterfeiting ink, wherein the conventional anti-counterfeiting ink used comprises the following main components in percentage by mass: 0.0002-40% of thickening agent, 0.0001-30% of identifiable material, 0.001-20% of penetrating agent and 10-90% of solvent, wherein the dosage is completely consistent with that of the specific embodiment in specific configuration, only the penetrating agent is removed, and the rest structures and preparation methods refer to the specific embodiment of the application.
When the anti-counterfeiting identification is carried out on the anti-counterfeiting paper prepared in the specific embodiment and the comparative example, the anti-counterfeiting paper can see the anti-counterfeiting image-text information on the paper core layer through the semitransparent paper surface layer to carry out the first anti-counterfeiting identification; and then, after the paper surface layers of the anti-counterfeiting paper are respectively uncovered, observing anti-counterfeiting image-text information on the inner paper core layer to perform second anti-counterfeiting identification. After the surface layer of the comparative paper is uncovered, the anti-counterfeiting image-text information on the paper core layer is uncovered along with the paper surface layer, and the anti-counterfeiting image-text information or the complete anti-counterfeiting image-text information cannot be seen on the paper core layer, because the anti-counterfeiting image-text information in the comparative paper can be fixed and dried only on the surface of the paper core layer and cannot permeate into the inside of the paper core layer and the back of the paper core layer, the anti-counterfeiting image-text information cannot be completely remained on the paper core layer after the paper surface layer is uncovered; when the anti-counterfeiting paper surface layer of the specific embodiment of the application is uncovered, although the most surface layer of the paper core layer has the part uncovered along with the paper surface layer, the most clear and complete anti-counterfeiting image and text information can be visually seen on the paper core layer or can be seen by a corresponding instrument, even the paper core layer is uncovered to be thicker, the most clear and complete anti-counterfeiting image and text information can be obtained, and the double anti-counterfeiting effect is high in reliability, good in anti-counterfeiting effect and not easy to imitate.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
