Patent documentation 1: the spy opens flat 8-118857
But, said method is conceived to the difficulty of the manufacturing or the recovery of optically diffractive structure, and fundamental purpose is the forgery of Stop message, and the technology prosperity that relates to optically diffractive structure now, only, be difficult to think on safety to be completely preventing simple transfer printing optically diffractive structure on the information of forging.In addition, in said method, utilize the thermal transfer mode printing to be printed in advance under the situation of the information on the transfer printing body, having the problem that does not make optically diffractive structure be adhered on this printing, be difficult to transfer printing.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of that utilize optically diffractive structure to prevent that information from forging or distorting to wait, realize the image forming method of greater security etc., even if or provide a kind of and utilize the part of thermal transfer mode formation in advance, also the image forming method etc. of optically diffractive structure can be set on this part.
The 1st image forming method of the present invention, the layer that comprises the optically diffractive structure that is arranged in the optically diffractive structure transfer sheet by transfer printing on the transfer printing body of recorded information, formation comprises the information of described record and the image of described optically diffractive structure, wherein, the layer that comprises described optically diffractive structure by transfer printing, so that in the corresponding relation of the information of described optically diffractive structure that is transferred and described record, form the information of expression regulation systematicness, thereby address the above problem.
According to forming the record images thing that forms by the present invention, can write down between the optically diffractive structure of the information that write down in the thing and transfer printing at this, produce predetermined rule, so under the situation of the information that will distort record, must so that the mode that also satisfies this systematicness based on the information of optically diffractive structure distort.Therefore, compare, more be difficult to distort or forge, can realize higher security with simple recovery or manufacturing optically diffractive structure.In addition, even if the information content that is recorded in advance in the transfer printing body changes, also because as long as transfer printing corresponding to the information of the content of this information, so information width is wide, can be used in the various uses.
So-called ' predetermined rule ' not only refer to be contained on the same record thing, promptly the information of corresponding record directly has the situation of particular kind of relationship with the information that optically diffractive structure forms, also comprising can be from the systematicness of the information derivation of the information of each record between a plurality of record things and the formation of each optically diffractive structure.Have the method for the information of this regulation systematicness as long as but the printing transferring method of optically diffractive structure is transfer printing with formation, then kinds such as no matter hot transfer printing, laser all can.So-called optically diffractive structure comprises the diffraction grating as the hologram of the interference fringe that forms the regulation shape relief pattern the same with conduct.Comprise so-called diffraction grating that repeats as the relief pattern of stipulating and the so-called hologram that constitutes by the interference fringe that shows the regulation shape in ' optically diffractive structure '.
The 1st record thing of the present invention, comprise by on the transfer printing body of recorded information, transfer printing comprises resulting, the described information that has write down of layer of the optically diffractive structure that is arranged in the optically diffractive structure transfer sheet and the image of described optically diffractive structure, wherein, the information that the information of described record and described optically diffractive structure by transfer printing are formed is corresponding, so that generate predetermined rule, address the above problem thus.
According to the present invention,, so as mentioned above, can provide high security because the optically diffractive structure of transfer printing in the record thing corresponding with the information of record with having predetermined rule.In addition, the information of described record also can be synchronous with the information that is formed by the described optically diffractive structure of transfer printing.Thus, only, just can provide high security by making information that forms by optically diffractive structure and the information synchronization that has write down.So-called synchronous information is meant visually, acoustically or in idea with the consistent information of information of record.The so-called consistent in idea relation that is meant for example Japanese and its translator of English etc., can associates identical things.
In addition, also can utilize the ink that to discern by luminous ray to print the information of described record.Thus, because information that can not identification record under luminous ray only can be discerned by the light beyond the luminous raies such as ultraviolet ray, so can realize higher security.
The 2nd image forming method of the present invention, have optically diffractive structure transfer printing process and ink offset operation, wherein said optically diffractive structure transfer printing process, from the optically diffractive structure transfer sheet to this transfer printing body, avoid the specific region of its transfer printing body, transfer printing comprises the optically diffractive structure layer of optically diffractive structure; Described ink offset operation from the stacked ink offset thin slice that comprises the ink layer of the invisible ink portion that is made of the ink that can't discern under the visible light on the substrate sheet, to the described ink layer of described specific region transfer printing, thus, addresses the above problem.
According to the present invention, owing to form image by the ink layer of the invisible ink portion that has that the ink that can't discern constitutes under luminous ray, so can be attached to the information that can't discern under the luminous ray.In addition, because transfer printing optically diffractive structure layer not in the specific region of transfer ink water layer, so by on the optically diffractive structure layer, ink layer being set, can make the edge of showy ink layer become unshowy, especially under the situation of the whole substantial transparent of ink layer, can't discern the existence of ink layer at a glance.Transfer printing in the ink offset operation, the situation that comprises transfer ink water layer only is with the situation with other layer of ink layer transfer printing, transfer printing in the optically diffractive structure transfer printing process, the situation that comprises transfer printing optically diffractive structure layer only is with the situation with other layer of optically diffractive structure layer transfer printing.
So-called ' ink that can't discern under luminous ray ' is meant under the light beyond the luminous ray by discernible so-called invisible ink such as fluorescence or color developments.' invisible ink portion ' can be ink layer integral body, also can be to be contained in the ink layer with the regulation shape.In invisible ink portion is under the situation of ink layer integral body, under the light beyond the luminous ray, and specific region integral fluorescence for example.
In that invisible ink portion is constituted under the situation of regulation shape, under the light beyond the luminous ray, in the specific region, can discern this shape.No matter how the order of optically diffractive structure transfer printing process and ink offset operation all can.In ' optically diffractive structure ', comprise so-called diffraction grating that repeats as the relief pattern of stipulating and the so-called hologram that constitutes by the interference fringe that shows the regulation shape.
Also can be after the described ink layer of described ink offset operation transfer printing, by the described optically diffractive structure layer of described optically diffractive structure transfer printing process transfer printing.At this moment, also can contain the transfer printing layer of described ink layer, described transfer printing layer is transferred to described transfer printing body by described ink offset operation in the upper strata stacked package of described substrate sheet, so as in the surface of described transfer printing layer residual comprise mould release the layer.Thus, owing to contain mould release in the surface of transfer printing layer, so the optically diffractive structure layer is not adhered on this surface.Therefore, can avoid the zone of transfer printing transfer printing layer and come transfer printing optically diffractive structure layer easily.
On the other hand, also can be after the described optically diffractive structure layer of described optically diffractive structure transfer printing process transfer printing, by the described ink layer of described ink offset operation transfer printing.Thus, need only the transfer ink water layer to imbed the not specific region of transfer printing optically diffractive structure.In addition, also can have linearity configuration in described specific region.Thus, because the specific region is the narrow gap shape of width, so, then more be difficult to confirm its existence as long as ink layer is transparent under luminous ray.In addition, if the specific region is formed the literal shape, then except that the existence of invisible ink, but added text information also, so higher security can be provided.
In addition, the present invention also can be embodied as the 2nd record thing with image, described image is provided with the ink layer comprise the invisible ink portion that is made of the ink that can't discern under luminous ray in the specific region, and is arranged to make the optically diffractive structure layer that comprises optically diffractive structure to avoid described specific region.

It is owing to comprise mould release in the surface of this part that the inventor is conceived to that optically diffractive structure is not adhered on the part by thermal transfer printing.According to the present invention, hot transfer sheet is stripped from layer and is separated into substrate sheet side and transfer printing layer, transfer printing layer is transferred on the transfer printing body by heat, with the residual peel ply that does not comprise mould releases such as paraffin, silicon, surface active material in fact in the surface, so the most surperficial peel ply that does not comprise mould release that becomes of the transfer printing layer on the transfer printing body.Therefore, can be on this peel ply bonding optically diffractive structure layer, make the optically diffractive structure layer further be transferred to heat and be needed on the transfer printing layer on the transfer printing body.
So-called ' peel ply ' is the general designation that is contained in ' transfer printing layer ', is positioned at the locational layer that separates with the substrate sheet side when the hot transfer printing of this transfer printing layer.Therefore, also can be not only to have separation function, also have a layer of other function.So-called ' peel ply is residual ' comprise peel ply former state in the hot transfer sheet be contained in the transfer printing layer, be transferred to the state that situation and a part at peel ply on the transfer printing body residue in the substrate sheet side after the substrate sheet side is separated under, from the situation of separating with the substrate sheet side of peel ply midway.
' transfer printing layer ' only comprise for the situation of peel ply and except that peel ply the situation of stacked other layer also.Only comprise the diffraction grating that repeats for relief pattern in ' optically diffractive structure ' and form the so-called hologram of the interference fringe of performance regulation shape.
Also can described transfer printing layer, the further stacked ink layer that contains ink on described peel ply, in described hot transfer printing process, the described transfer printing layer of hot transfer printing is so that form specific shape on described transfer printing body.Thus, can make the given shape that is formed on the transfer printing body by transfer printing layer have special implication, can be with this shape as information.Especially so long as discernible ink under the visible light, then the user can discern this specific shape.Because this shape forms with thermal transfer mode, so can change this shape where necessary easily.So-called ' given shape ' is so long as discernible shape gets final product sign of inclusion, literal, apperance etc.
Also can be in the operation of the described optically diffractive structure layer of transfer printing, the described optically diffractive structure of transfer printing on a part that is needed on the described transfer printing layer on the described transfer printing body.Thus, owing to not exclusively cover the transfer printing layer that is needed on the transfer printing body, so, also can discern the transfer printing layer of transfer printing even if under the opaque situation of transfer printing layer.
In addition, the present invention also can be embodied as the 3rd record thing, promptly has the image that comprises the hot transfer printing portion that is formed by hot transfer printing and be laminated in the optically diffractive structure in this hot transfer printing portion, wherein, in the face of the described optically diffractive structure of contact of described hot transfer printing portion, do not contain mould release.
As mentioned above, according to the present invention, a kind of manufacture method that writes down thing etc. can be provided, this method is arranged on optically diffractive structure in the optically diffractive structure transfer sheet by transfer printing, so that with the information corresponding relation that is recorded on the transfer printing body in, form the information of expression regulation systematicness, can utilize optically diffractive structure to prevent the forgery of information thus or distort etc., realize the security of height.
In addition, a kind of image forming method etc. can be provided, this method is by avoiding the specific region of transfer printing body, transfer printing optically diffractive structure layer, have the ink layer of the invisible ink portion that constitutes by the ink that under luminous ray, can't discern to this specific region transfer printing, have the optically diffractive structure that high security is provided that can't only under luminous ray, can imitate at a glance thus.

Embodiment
1. the 1st mode
Fig. 1 is the figure of expression as the sealing gasket with record images thing 1 that forms in the 1st mode.As being recorded in the information of record in the thing 1, comprise: the printing information portion 2 of date of printing, to shape ' A ' implement three-dimensional hologram hologram portion 3, implement the travers shape diffraction grating diffraction grating portion 4 with form the diffraction grating information portion 5 of same date mutually with printing information portion 2 by diffraction grating.Below, the method that forms the image that writes down thing 1 is described.
Optically diffractive structure among the present invention is meant diffraction grating or hologram, is formed among the optically diffractive structure cambium layer 20d.As shown in Figure 4, the optically diffractive structure cambium layer 20d of the manner constitutes integral body by diffraction grating paper tinsel 20d-1, is provided with the 20d-2 of hologram portion that the shape ' A ' of 3D computer hologram is implemented in expression with predetermined distance.Diffraction grating paper tinsel 20d-1 and the 20d-2 of hologram portion are transferred on the transfer printing body 10 by method described later, form the hologram portion 3 or the diffraction grating information portion 5 of record thing 1 respectively.
Be arranged on the diffraction grating among the optically diffractive structure cambium layer 20d and the interference fringe of hologram, can be as the surface have that the embossment (relief) of relief pattern writes down, along the thickness direction stereo recording or be recorded as in transmitance and change any of interference fringe that the light amplitude that causes causes diffraction under changing.Particularly, white light reconstructing hologram, the holographic stereogram that utilizes these principles, color holograms etc. such as laser reconstruction holograms such as Fresnel hologram, figure image hologram, Lippmann hologram, colour (rainbow) hologram are arranged.
These holograms are by previously known method manufacturing and be made as optically diffractive structure cambium layer 20d and get final product.In addition, optically diffractive structure cambium layer 20d preferably has the cementability that is adhered on the transfer printing body 10.Produce the raw material of cementability as long as suitably determine corresponding to the raw material that constitutes transfer printing body 10 surfaces.In addition, when the material that constitutes optically diffractive structure cambium layer 20d is transferred on the transfer printing body 10, can not print complete hidden printing information 2 because of size (point) with incomplete hidden printing information 2.
Back side slip layer 20a is provided with the generation that prevents to heat the so-called adhesion phenomenon that causes.Therefore, require thermotolerance, the high back side slip layer 20a of hot landing (heat sliding property).Peel ply 20c is provided with for the fissility that improves optically diffractive structure cambium layer 20d and substrate sheet 20b.The material that constitutes is as long as suitably determine corresponding to substrate sheet 20b.As long as substrate sheet 20b has to a certain degree rigidity and thermotolerance.The integral thickness of optically diffractive structure transfer sheet 20 is preferably the thickness that does not hinder from the heat conduction degree of heating head.
The optically diffractive structure cambium layer 20d side of the optically diffractive structure transfer sheet 20 with above-mentioned formation is overlapped with the surface of transfer printing body 10, heat from back side slip layer 20a side by heating head.Peel ply 20c corresponding to the part that is heated peels off from substrate sheet 20b, and optically diffractive structure cambium layer 20d is transferred on the transfer printing body 10.That is, the optically diffractive structure cambium layer 20d corresponding to the heating location of heating head is transferred on the transfer printing body 10.Therefore, if back side slip layer 20a is not had the ground of omission heating regulation area, then transfer printing has the optically diffractive structure cambium layer 20d corresponding to the regulation area of this heating location, if describe the heating of regulation shape ground, transfer printing optically diffractive structure cambium layer 20d then is to describe the regulation shape corresponding to this heating location.
In the manner, at first, there be not the scope of ground heating of omitting by heating head corresponding to the 20d-2 of hologram portion from back side slip layer 20a side.Thus, the optically diffractive structure cambium layer 20d corresponding to the 20d-2 of hologram portion is transferred on the transfer printing body 10 formation hologram portion 3.This state as shown in Figure 5.At this moment, a heating head is not had with omitting move heating, or also can once heat this scope by heating head with a plurality of heating.
