The specific embodiment:
Anti-false fiber among Fig. 1 a, constitute corpus fibrosum 2 by geometric cross section 4, corpus fibrosum 2 is made up of upper surface 3 and lower surface 3a, upper surface 3 and lower surface 3a are concavo-convex barrier structure, the concavo-convex barrier structure of present embodiment upper surface is that cross section is the face 3 ' and the face 3 at two hypotenuse places of the rib at drift angle place of triangular element and drift angle " the convex barrier structure that constitutes, the convex barrier structure of lower surface is identical with upper surface.Upper surface 3 is distributed with two characteristic pattern A and B, is distributed in face 3 ' and face 3 respectively " on, tangible vision difference is arranged between characteristic pattern A and the B, make when observing upper surface or lower surface from different perspectives, can see characteristic pattern A and B respectively.Characteristic pattern A and B can be separately or are covered with the face 3 ' and 3 at its place jointly ", make vision difference more obvious.As observing this face, then can see A, from perpendicular to face 3 from angle a perpendicular to face 3 ' " angle sightingpiston 3 ", then can see B.And during respectively from this two angles observation, concavo-convex barrier structure can block a pattern characteristics fully, only sees a pattern characteristics, and promptly the concavo-convex barrier structure of present embodiment is complete barrier structure.If from perpendicular to the c of rib to observation, then can see the compound pattern of characteristic pattern A and B.Lower surface also can similarly be provided with this characteristic pattern, also has same visual effect.On the surface, concavo-convex barrier structure also can be distributed on the part surface of upper surface and/or lower surface above and/or under the concavo-convex barrier structure of present embodiment was distributed in fully.
Fig. 1 b is the schematic diagram that an anti-false fiber embeds anti-fake material.1 is anti-fake material among Fig. 1 b, and 1 ' is the surface that has presented the upper surface 3 of corpus fibrosum 2, and the lower surface of corpus fibrosum 2 can be presented on another surface of anti-fake material.At least two the characteristic pattern A and the B of the corpus fibrosum 2 that distributes in the anti-fake material 1 are included in the characteristic pattern that manifests such as under visible light, ultraviolet ray, infrared ray and other non-visible lights, for the characteristic pattern that manifests under the visible light, anti-fake material 1 can realize that a line is false proof, and is promptly popular false proof; For the characteristic pattern that manifests under ultraviolet ray, infrared ray and other non-visible lights, then the available dedicated instrument is judged, can realize that the two wires is false proof.On the very thin corpus fibrosum 2 that distributes in the anti-fake material 1 concavo-convex barrier structure is set, and concavo-convex barrier structure is positioned on the upper surface 3 of corpus fibrosum, and upper surface 3 can be presented at least one surface 1 of anti-fake material ' on, therefore the observer observes from the different angles on this surface 1 ' of anti-fake material 1, because blocking of concaveconvex structure, can see the different characteristic pattern of upper surface respectively, and produce tangible vision difference, have antifalse effect.Because this vision difference is to be blocked by concaveconvex structure by the pattern characteristics that distributes on the anti-false fiber upper surface 3 in the anti-fake material to cause, realize promptly that also above-mentioned purpose is determining in the occlusion effect of different angles to light owing to the meticulous concavo-convex barrier structure of fiber surface, and all at present printing processes (no matter being flat stamping, Kong Yin, protruding seal, duplicating, spray printing, gravure or the like) all can't copy this stereochemical structure, so the utility model can effectively be stopped the counterfeit of printing technology.
There is diversity in the utility model vision difference:
At least two characteristic pattern A of the anti-false fiber that distributes in the utility model anti-fake material and B are blocked by concavo-convex barrier structure and are seen that respectively the vision difference of generation is diversified, this vision difference be with characteristic pattern in the different distributions of the anti-false fiber part surface at different concavo-convex barrier structure places and the different visions that can bring are relevant.
As previously mentioned, embodiment shown in Fig. 1 a shows is the distribution that a kind of distribution of characteristic pattern can be blocked by concavo-convex barrier structure fully each other, because barrier structure is to extend along corpus fibrosum 2 length directions, therefore only have significant change because of blocking perpendicular to the different visions of corpus fibrosum 2 length directions are just possible, because corpus fibrosum 2 is very thin, the maximum gauge of suggestion corpus fibrosum cross section preferably is no more than 0.25mm, therefore the anti-false fiber width that can see perpendicular to corpus fibrosum 2 length directions is very limited, die from a visual angle when change at the b visual angle, must be that characteristic pattern A is different with B could could produce tangible vision difference, could be observed by people's eyesight.Just different people's the twenty-twenty visions that can make with B of present embodiment characteristic pattern A are observed sudden change, and this difference preferably only is the difference of color, also can be the differences of pattern and color is identical, can also be that color is all different with pattern.Present embodiment anti-fake material 1 surface 1 ' is gone up and is had at least two viewing angle a and b, when a angle is observed the described part surface of anti-false fiber, see characteristic pattern A and characteristic pattern B is blocked by the triangle convex barrier structure on corpus fibrosum 2 upper surfaces 3 and cannot see, when the b angle is observed corpus fibrosum 2 upper surfaces 3, see characteristic pattern B and characteristic pattern A is blocked by the triangle convex barrier structure of corpus fibrosum 2 upper surfaces 3 and cannot see; False proof for the two wires, promptly observe by instrument, present embodiment then can not be subjected to the necessary different restriction of characteristic pattern A and characteristic pattern B, is identical such as characteristic pattern A and characteristic pattern B in people's twenty-twenty vision scope, but one of them has carried out certain non-visible light and has handled, then under the instrument that can discern this non-visible light, just can see both vision differences, produce antifalse effect.It is a kind of pattern that does not have the overlapping region to separate fully with B position relation that the setting of convex barrier structure upper surface 3 on corpus fibrosum 2 of present embodiment makes pattern characteristics A, can realize the visual effect of being blocked fully each other.
At least two characteristic pattern A and B on upper surface 3 significantly vision difference also can be that a certain characteristic pattern can not be blocked and another feature pattern can be blocked the different visual effects of generation fully fully, this visual effect is brought owing to the inclusion relation of characteristic pattern often, be included in fully among the characteristic pattern B such as characteristic pattern A, promptly the time from a angle observation anti-false fiber upper surface 3, the concavo-convex barrier structure of anti-false fiber upper surface 3 makes eyesight can only see characteristic pattern A and has blocked characteristic pattern B fully, and the concavo-convex barrier structure of anti-false fiber upper surface 3 makes eyesight can only see characteristic pattern B and characteristic pattern A is not blocked when the b angle is observed anti-false fiber upper surface 3.The characteristic pattern A and the B that produce this vision difference must be inequality, and the color of characteristic pattern is inequality at least, to produce strong vision difference.
It also can be the visual effect that produces all can not block fully the time, this situation can be that characteristic pattern A is two patterns that do not have the overlapping region to separate fully with characteristic pattern B, promptly the time from a angle observation anti-false fiber upper surface 3, the concavo-convex barrier structure of anti-false fiber upper surface 3 makes the people can only see characteristic pattern A and has blocked the part of characteristic pattern B, the concavo-convex barrier structure of anti-false fiber upper surface 3 makes and can only see characteristic pattern B and blocked a characteristic pattern A part when the b angle is observed anti-false fiber upper surface 3, though this moment, B or A were not blocked fully, but since its quite a few be blocked, the part that it can be seen by the people is because the resolving power of human eye, what see may be a kind of pattern of characteristic pattern A and characteristic pattern B combination, rather than simple characteristic pattern A adds that characteristic pattern B or characteristic pattern B add characteristic pattern A.The characteristic pattern A and the B that produce this tangible vision difference also must be inequality, and color character is inequality at least.
It can also be the vision difference that brings along the visual transform of fibre length direction jumping characteristic because of being blocked, because the sight line anti-false fiber length direction people can be longer, (length of anti-false fiber preferably is no more than 15mm, but 0.2mm can bring much longer sight line than its width), therefore as at least two characteristic pattern A and B during along anti-false fiber length diverse location (rather than distribute vertically as Fig. 1 a) distribution, can produce the visible change of great-jump-forward, when characteristic pattern is the color characteristic pattern, be elaborated below this visible change.This visible change requires relatively lowly to characteristic pattern, and promptly characteristic pattern can be identical, as long as in the residing position of anti-false fiber length direction obvious vision difference is arranged, just can produce the visible change of great-jump-forward.
The diversity of the utility model characteristic pattern and the visual effect of bringing thereof:
At least two characteristic pattern A and B can be the patterns that various lines, literal etc. are formed, and also can be the patterns that color, lines, literal etc. are formed, and can also only be above-mentioned individual elements, as only being character pattern, only are colors.Because the anti-false fiber very thin in the utility model anti-fake material, false proof for the line that practicality is higher, discern simple more direct, then be worth high more, because color characteristic is the feature that normal person's eyesight is convenient to differentiate most, only be that the situation of color characteristic pattern is fully set forth at two characteristic pattern A and B below therefore.
Still see Fig. 1 a, characteristic pattern A and characteristic pattern B have vitta A and the tint B that the different colours feature is parallel to each other, for example vitta A is red, tint B is blue, when observing anti-false fiber upper surface 3, a angle can only see red bar and blue bar is blocked by the concavo-convex barrier structure on the anti-false fiber upper surface 3 and be cannot see, at this moment, ordinary people's sensory fibre is red, when observing anti-false fiber upper surface 3, the b angle can only see red bar and blue bar is blocked by the concavo-convex barrier structure on the anti-false fiber upper surface 3 and be cannot see this moment, ordinary people's sensory fibre is red, when observing anti-false fiber upper surface 3, the c angle can see red bar and blue bar simultaneously, superfine and extremely near apart owing to vitta, ordinary people's the tertiary colour effect of feeling red bar and blue bar, promptly fiber is a black.
It is parallel with the length direction of anti-false fiber with tint B to have the vitta A that the different colours feature is parallel to each other among the embodiment that Fig. 1 a shows, when changing angle and observing, whole fiber becomes blueness by redness, has the visual transform effect of uniqueness.The translation-angle that is transformed to angle b by angle a preferably is not more than 120 degree.The design's visual signature is that its fiber color change is the most obvious when changing angle observation fiber surface perpendicular to the fibre length direction.
Fig. 2, Fig. 3 characteristic pattern A and characteristic pattern B are respectively the combination patterns with the combination pattern of vitta A1, A2 that the different colours feature is parallel to each other, A3 and tint B 1, B2, B3, and vitta A1-A3 is vertical with the length direction of anti-false fiber with tint B 1-B3.The design's visual signature is that its fiber color change is the most obvious when changing angle observation fiber surface along the fibre length direction.
Characteristic pattern A and characteristic pattern B are respectively the combinations with the combination of vitta A1, A2 that the different colours feature is parallel to each other, A3 and tint B 1, B2, B3 among Fig. 4, the crossing angle of the length direction of A1-A3 and B1-B3 and anti-false fiber is between the 0-90 degree, the design's visual signature is when being to change angle again and observe fiber surface with fibre length direction inclination respective angles, and its fiber color change is the most obvious.
Characteristic pattern A is that pattern is identical, color characteristic is also identical with characteristic pattern B, but characteristic pattern A and the different situation in the position of characteristic pattern B on length direction on the anti-false fiber see Fig. 5, for example, vitta A and tint B are all to be black, vitta A is distributed in the first half of fiber, is made of A1, A2, A3, and tint B is distributed in the latter half of fiber, constitute by B1, B2, B3, when changing the angle observation, whole fiber moves at the beat type occurrence positions, has unique visual transform effect.
For characteristic pattern A and characteristic pattern B is that pattern is identical, color characteristic is different, but characteristic pattern A is different with the position of characteristic pattern B on length direction on the anti-false fiber.Still see Fig. 5, for example, vitta A is red, tint B is a black, and vitta A is distributed in the first half of fiber, and tint B is distributed in the first half of fiber, when changing the angle observation, whole fiber becomes black by redness and the beat type occurrence positions moves, and has unique visual transform effect.
Fig. 6 a-d is characteristic pattern A and characteristic pattern B axial distribution but the different situation of lengthwise location on anti-false fiber, characteristic pattern A and characteristic pattern B on length direction on the anti-false fiber can be the position overlapping fully or overlap or part is joined or from.Fig. 6 a: vitta A is red, and tint B is a black, and vitta A and tint B are complete when overlapping, and when changing angle and observing, whole fiber becomes black by redness, and the position of fiber is not subjected to displacement, and has unique visual transform effect; Fig. 6 b: when vitta A and tint B were overlapped, when changing the angle observation, whole fiber becomes black by redness and the beat type occurrence positions moves, but the less unique visual transform effect that has of beating; Fig. 6 c: when vitta A and tint B intersected, when changing the angle observation, whole fiber becomes black by redness and the beat type occurrence positions moves, and is end to end but beat; Fig. 6 d: vitta A and tint B from the time, when changing angle and observing, whole fiber becomes black by redness and the beat type occurrence positions moves, but moving of the great-leap-forward of beating has unique visual transform effect.
Fig. 7 a is the situation of the color various combination of characteristic pattern A or characteristic pattern B, and its color can be monochromatic, or polychrome is compound.For example, vitta A is made up of the lines of two end to end different colours, and one is that red A1, one are green A2, and tint B is a black, and when changing angle and observing, whole fiber becomes the monochromatic lines of black, visual effect uniqueness by the red and green color lines.
When characteristic pattern was color characteristic, color can be a white, or colourless or identical with anti-fake material surface color color.If vitta A is red among Fig. 7 b, tint B is a white, and tint B is distributed on whole convex surfaces 3 ' of anti-false fiber, if the anti-fake material surface is a white, when changing the angle observation, whole fiber becomes fiber by redness and disappears, and has unique visual transform effect; Be black such as vitta A also, tint B is red, and tint B is distributed on whole convex surfaces 3 ' of anti-false fiber, if the anti-fake material surface is red, when changing angle and observing, whole fiber becomes fiber by black and disappears, and has unique visual transform effect.
Corpus fibrosum will have antifalse effect in anti-fake material, be controlled in the actual production process the effective concavo-convex barrier structure of corpus fibrosum and necessarily be presented on the anti-fake material surface and be absolutely necessary.According to theory analysis and a large amount of experimental results show that, in paper-making process, when fiber has certain elastic hardness, the maximum projection plane of whole fiber shape is not necessarily up and be presented on the surface of paper, the projected area of the utility model anti-false fiber is meant the minimum square area of its entity projection line correspondence, that is: when fiber be that the cross section of straight line and fiber waits simultaneously in the longitudinal direction, the area of the entity projection line that minimum square area is a fiber is seen Figure 16 a; When fiber be straight line and fiber cross section in the longitudinal direction not simultaneously, the widest part of the entity projected area that minimum square area is a fiber and the product area of fibre length are seen Figure 16 b; When fiber was sweep, minimum square area was the square of a crooked projection line of the entity that just covers fiber, sees Figure 16 c.
Another kind of description is the same with above-mentioned actual effect, remove to comprise corpus fibrosum 2 with side's body, two surfaces of maximum of minimum side's body that can all comprise anti-false fiber are during corresponding to the upper surface 3 of anti-false fiber, because energy state was minimum when minimum side's body kept flat, inevitable towards the anti-fake material surface, the upper surface 3 that therefore has concavo-convex barrier structure can be presented on the anti-fake material surface.
After if expectation corpus fibrosum 2 adds anti-fake material, its surface energy with concavo-convex barrier structure is presented on the surface of anti-fake material naturally, in view of the above, the utility model anti-false fiber also has following special construction, these designs are applicable to too anti-false fiber are distributed in the interlayer of one deck paper, or be distributed in the interlayer of one deck plastic film, or be distributed in one deck single layer plastics films:
Corpus fibrosum 2 is curved shapes, and the upper surface of curved fiber is an anti-false fiber body upper surface 3, sees Figure 12.The cross section of anti-false fiber length direction at the Breadth Maximum c that is parallel to the anti-fake material surface smaller or equal to cross section at Breadth Maximum d perpendicular to the anti-fake material surface, just the major axis d of the cross section of corpus fibrosum 2 length directions and anti-fake material surface is vertical.See Figure 13, therefore when fiber was bending, its cross section can not be that flat still can make the upper surface 3 of the anti-false fiber that needs be presented on the surface of paper.The horizontal maximum length of crossing over because of bending of curved fiber body 2 is its geometric widths e, see Figure 12, when this geometric widths e be at least the fibre length direction cross section major axis d length more than two times the time, corpus fibrosum 2 can be presented on the surface of anti-fake material fully by its natural camber.
If it is flat that corpus fibrosum 2 has a part of C at least at the cross section of fibre length direction, the flat horizontal surface of flat correspondence is presented on the surface of anti-fake material, sees Figure 14.Also can be that corpus fibrosum 2 all is a flat at the cross section of fibre length direction, the flat horizontal surface of flat correspondence be presented on the surface of anti-fake material.The flat part of corpus fibrosum 2 is preferably colourless, or white, or the color surperficial identical with anti-fake material.
If the outer pancake transparent material of one deck that covered of anti-false fiber, the plane and the transparent material flat pattern maximum projection plane that corpus fibrosum 2 are divided into upper surface and lower surface are same plane or in parallel, this flat pattern maximum projection plane is the perspective plane of flat horizontal surface 5; Change kind of a describing method: if promptly the upper surface of corpus fibrosum 2 and lower surface correspond respectively to two maximum surfaces of minimum side's body that can comprise described transparent material, and the relative plane of flat horizontal surface that these two maximum surfaces are the flat pattern transparent material, upper surface 3 is on the surface of the anti-false fiber of flat horizontal surface 5 correspondences of transparent material so.See Figure 15 a-d, the flat horizontal surface 5 of flat correspondence is presented on the surface of anti-fake material, and the upper surface 3 of corpus fibrosum 2 is corresponding with flat horizontal surface 5, towards identical, so also present the surface of anti-fake material 1.Because flat covers the physical efficiency nature outward and is presented on the anti-fake material surface with flat horizontal surface 5, so the upper surface with concavo-convex barrier structure 3 of the utility model anti-false fiber also is presented on the surface of anti-fake material certainly naturally.
Concavo-convex barrier structure of the present utility model has diversity:
Concavo-convex barrier structure is that the anti-false fiber cross section has a triangular element at least, see Fig. 1 a and Fig. 2, cross section 4 is a triangular element, and characteristic pattern A is on the face 3 ' at a leg-of-mutton hypotenuse place, and characteristic pattern B is at leg-of-mutton another hypotenuse place face 3 " on.Triangle is to realize presenting the typical concavo-convex barrier structure that a characteristic pattern shelters from another characteristic pattern, and present embodiment is not more than 120 degree by the translation-angle that angle a transforms to angle b, and then vision difference is more obvious.
Concavo-convex barrier structure is to be made up side by side by a plurality of triangles, sees Fig. 8, on the corresponding hypotenuse of each triangle all characteristic patterns constitute characteristic pattern A, all characteristic patterns constitutes characteristic pattern B on another corresponding hypotenuse of each triangle.Because fiber is very thin, the concavo-convex barrier structure that single triangle forms is difficult to be presented on the anti-fake material surface flatly, because the sensitivity of flat triangle characteristic pattern conversion when changing viewing angle is not high, and can be very thin at fiber width one timing vitta A or tint B, can influence visual effect.Therefore, the triangle of the utility model design makes up side by side and can remedy above-mentioned deficiency.
Concavo-convex barrier structure be have at least one trapezoidal, see Fig. 9, characteristic pattern A is on a trapezoidal hypotenuse, characteristic pattern B is on another trapezoidal hypotenuse.The utility model is designed to trapezoidal, is because trapezoidally have a flat structure, the flat horizontal surface that it not only can make fiber up, and because trapezoidal hypotenuse can be done more tiltedly, thereby the sensitivity that can guarantee characteristic pattern conversion when changing viewing angle is higher.
Concavo-convex barrier structure is to have a dimple-shaped at least, see Figure 10, totally three pits, characteristic pattern A is positioned at place, limit face above the dimple-shaped, by characteristic pattern A1, A2, A3 forms, be A1, A2, A3 constitutes overall characteristic pattern A, characteristic pattern B is on the anti-false fiber face of place, dimple-shaped base, by characteristic pattern B1, B2, B3 forms, characteristic pattern A is positioned at place, limit face above the dimple-shaped, characteristic pattern B is on the anti-false fiber face of place, dimple-shaped base, when with the part surface of enough this barrier structures of angle of inclination observation band, can only see characteristic pattern A, when when seeing perpendicular to the angle of upper surface 3, can see characteristic pattern A and characteristic pattern B, if pit is enough little, observing what see from angle vertical and that tilt a little is characteristic pattern A and A and certain pattern that B is combined into, and the anti-false fiber that promptly has this concavo-convex barrier structure is when the observation anti-fake material that it presented is surperficial, concavo-convex barrier structure can block characteristic pattern B fully, but can not block characteristic pattern A.
The limit of described concavo-convex barrier structure can be an arc, comprises convex and spill, sees Figure 11 a and 11b, can be flanging or toothed edge also, sees Figure 11 c.
Prior art will realize that the method for this structure is very ripe, a kind of is to adopt the multicomponent composite spinning method, a kind of is to adopt meticulous printing technology to stamp colored fine rule at smooth fiber, smooth fiber surface is being hot pressed into concavo-convex barrier structure and with the diverse location of different multi-color cord hot pressing on concavo-convex barrier structure surface then.Certainly also have other multiple processing methods.
