Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a printed matter obtained by forming an image on a protective layer transfer ribbon in advance, and thermally transferring both the protective layer and the image to a transfer material, and a protective layer transfer ribbon used for this.
[0002]
[Prior art]
As an ID card such as an employee card or a membership card, an image display body on which a face image or the like is recorded is used to authenticate that the owner is the owner. Such an image display is usually provided with a printing section for recording personal information such as a face image, a name, a date of birth, and an ID number by using a dye thermal diffusion recording method or a thermal fusion transfer recording method, and a recorded image. It is formed by an ID certificate manufacturing apparatus provided with a protective layer transfer portion for transferring a resin layer for protecting the surface, for the purpose of protecting paper and characters from ultraviolet rays and improving mechanical strength.
[0003]
Naturally, such an ID card is required to be able to maintain sufficient image quality for a long period of time. However, in the dye thermal diffusion recording method described above, a thermoplastic resin layer is provided on a support, and images and characters are recorded by thermally diffusing the dye into the thermoplastic resin layer. Is easily damaged. Therefore, the dye thermal diffusion recording method has a problem in durability of images and characters.
[0004]
As a method for improving the durability of images and characters of an ID card, a method of forming a protective layer on the surface of a card on which personal information is formed is widely used. For example, a protective layer transfer ribbon obtained by applying a thermoplastic resin such as a polyester resin to a thickness of about 3 to 5 μm on a support made of PET or the like and further drying the same is heated and heated by a heat roller from the support side. A thermal transfer method in which a protective layer made of a polyester resin or the like is transferred to the surface of a certificate by applying pressure has been put to practical use.
[0005]
In addition, an intermediate transfer type image recording is performed in which printing by the dye thermal diffusion recording method or the heat-sensitive melt transfer recording method is performed on the protective layer side, and then the protective layer is thermally transferred to the surface of the certificate by applying heat and pressure from the support side with a heat roller. A method has been put into practical use (for example, see Patent Document 1).
[0006]
However, in these methods for forming the protective layer, when a thick hard transfer material such as a card is used, the protection layer can be easily transferred over the entire transfer material, and a good-looking and good printed matter can be obtained. Since a thin and soft material to be transferred such as paper or synthetic paper is liable to be deformed or displaced during transfer, the length of the pressure contact surface of the heat roller must be longer than the length of the material to be transferred. As a result, there is a problem that the protective layer forming layer of the protective layer transfer ribbon is thermally transferred and adheres to the backup roller facing the heat roller. Also, if the shape of the heat roller is formed with a convex portion only on the pressure-bonded surface in order to transfer to a part of the material to be transferred, there is a problem that the material to be transferred is creased at the edge of the convex portion and the appearance is impaired. If the portion is not formed, a protective layer that is not adhered to a portion of the end of the transfer material that is not desired to be transferred is generated in a burr-like manner, causing a problem that the appearance is impaired.
[0007]
On the other hand, it is necessary to prevent unauthorized use of personal authentication media such as ID cards. For this reason, a countermeasure for preventing fraud that is difficult to forge and that can be easily determined as true or false is required.
[0008]
As a well-known technique that can respond to these demands, there is the addition of a hologram and a seal on the surface of a certificate that is put to practical use in cash cards and the like. In particular, a transparent hologram does not have a disadvantage that a margin for recording a person image, character information, and the like is reduced. In addition, an image receiving / adhesive layer is provided in advance on the transparent hologram, and after forming an image thereon, the image receiving / adhesive layer with the transparent hologram is thermocompression-bonded or thermally transferred to a base material such as paper and plastic. Thereby, a transparent hologram, a person image, character information, and the like can be simultaneously formed.
[0009]
As described above, it is common to form the functional resin layer and the image receiving / adhesive layer in two or more layers. However, the formed resin layer is peeled off with heat, an organic solvent, or the like to scrape off a person image or character information. Thus, falsification is easy, for example, fake information can be formed on a resin layer, or fake information can be formed on a base material such as paper and plastic.

BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to a first aspect has been made in order to solve the above-mentioned problems, and a method for manufacturing a printed matter in which a protective layer is thermally transferred to a material to be transferred using a protective layer transfer ribbon by a heating and pressing member and a backup member. And
Forming an image in an image area on the protective layer forming layer,

The surface of the protective layer forming layer provided with the image and the transfer prevention resin layer is positioned so as to face the transfer material, the heating / pressing member is brought into contact with the support, the backup member is brought into contact with the transfer material, and heating is performed. And a step of thermally transferring the image, the anti-transfer resin layer and the protective layer onto the material to be transferred by applying pressure.
[0016]
The invention according to a second aspect is a protective layer transfer ribbon used in the method for producing a printed matter,
A support,
A protective layer forming layer formed on the support,
An image formed in an image area on the protective layer forming layer,
A transfer-preventing resin layer formed in a non-image area on the protective layer forming layer and having a lower affinity with the transfer material and the backup member than with the protective layer.
[0017]
In the present invention, before transferring the protective layer to the material to be transferred, the transfer prevention resin layer whose affinity with the surface of the heating and pressing member used for thermal transfer of the material to be transferred and the protective layer is weaker than the affinity with the protective layer, It is formed on the surface of the protective layer in the non-image area. Accordingly, even if the pressure-bonding surface length of the heating and pressing member is longer than that of the material to be transferred and the backup member facing the heating and pressing member and the protective layer forming layer of the transfer ribbon are in contact with each other, the heating and pressing is unnecessary. No resin will adhere to the backup member.
[0018]
Further, when the present invention is used, a portion where the protective layer is not transferred can be formed according to the shape of the anti-transfer resin layer whose affinity with the surface of the material to be transferred and the heating / pressing member is weaker than the affinity with the protective layer. It is possible to provide a printed material that is extremely difficult to alter.
[0019]
Hereinafter, the present invention will be described in more detail with reference to the drawings. In each of the drawings, similar members are denoted by the same reference numerals, and redundant description will be omitted.
[0020]
1 to 3 are views showing an example of a production process of a printed matter according to the present invention.
[0021]
As shown in FIG. 1, first, a protective layer transfer base material 8 having a support 1 and a protective layer forming layer 2 provided on the support 1 is prepared.
[0022]
FIG. 2 is a sectional view illustrating an example of the protective layer transfer ribbon according to the present invention. As shown in FIG. 2, the protective layer transfer ribbon 10 has an image layer 3 formed on a protective layer transfer base material 8 and, for example, a rectangular image is formed in a non-image area outside the image area where the image layer 3 is formed. The shape can be obtained by forming the transfer prevention resin layer 4 having an affinity with the transfer material and the backup roller that is weaker than the affinity with the protective layer forming layer 2.
[0023]
Thereafter, as shown in FIG. 3, the surface of the protective layer forming layer 2 on which the image layer 3 and the resin layer 4 are formed is brought into contact with one surface of the material 5 to be transferred, and the support 1 is heated. The backup roller 7 is disposed on the other surface of the pressure roller 6 and the transfer material 5 so as to face each other, and is heated by a heat source (not shown) while applying a load, thereby protecting the transfer material 5 together with the image layer 3. Layer 2 is thermally transferred.
[0024]
In the manufacturing process shown in FIGS. 1 to 3, the affinity of the resin layer 4 formed in the non-image area outside the image area with the heating / pressing roller 6 is higher than the affinity with the protective layer formation layer 2. Because of its weakness, the backup roller 7 easily contacts the resin layer 4 during thermal transfer even if the pressure-bonded surface length of the heating / pressing roller 6 is longer than the length of the material 5 to be transferred, and contacts the protective layer forming layer 2. Difficult to do. This can prevent the protective layer forming layer 2 from adhering to the backup roller 7. Further, since the resin layer 4 has a lower affinity for the transfer material 5 than the affinity for the protective layer forming layer 2, it is not transferred onto the transfer material 5 during thermal transfer. As a result, a good-looking printed matter without burrs can be obtained, and the protective layer does not adhere to the backup roller.
[0025]
FIG. 4 is a sectional view showing an example of a printed material that can be formed by the present invention.
[0026]
If necessary, for example, by peeling the support 1 together with the resin layer 4, as shown in FIG. 4, the transfer material 5, the image layer 3 formed in the image area of the transfer material 5, and the image layer 3 The printed matter 20 having the protective layer 2 formed on the transfer material 3 and on the portion other than the peripheral portion of the transfer material 5 is obtained.
[0027]
FIG. 5 is a front view illustrating an example of an ID card that can be formed according to the present invention.
[0028]
As shown in the figure, the ID card 30 includes an image 16 and a protective layer 2 formed so as to cover the image 16, and the protective layer 2 includes an ID peripheral portion which is a part of a non-image area. 5 is formed in the region except for the region 5.
[0029]
As shown in FIG. 5, the protection layer 2 is not formed on the entire surface of the ID card, so that it is difficult to falsify.
[0030]
FIG. 6 is a diagram showing a modification of the ID card shown in FIG.
[0031]
As shown in the figure, the ID card 40 has the same structure as that of FIG. 5 except that a protective layer 9 whose end is formed in a waveform is provided instead of the protective layer 2.
[0032]
When heating with a thermal head using an ink ribbon or the like on which an ink layer and a resin layer are formed, if heating is performed in a predetermined shape, for example, in the form of a pattern such as a character or a picture, such a portion may be provided in a portion without a protective layer. A pattern such as a character or a picture can be formed.
[0033]
In the ID card 60 shown in FIG. 6, in particular, since the protection layer 9 having the end portion of the predetermined shape is provided, it is more difficult to falsify.
[0034]
FIG. 7 is a schematic diagram illustrating an example of a printing apparatus that can be used in the present invention.
[0035]
As shown in the drawing, the printing device 70 includes a printing unit 33 functioning as a printing unit, and a transfer unit 34 functioning as a transfer unit provided below the printing unit 33.
[0036]
The printing unit 33 includes a thermal head 35, a platen roller 36 disposed to face the thermal head 35, and the like. Between the thermal head 35 and the platen roller 36, the affinity between the heat-meltable ink layers of, for example, yellow, magenta, and cyan, the material to be transferred, and the backup member is weaker than the affinity with the protective layer forming layer. An ink ribbon 37 having a transfer prevention resin layer forming layer is interposed. The platen roller 36 functions as a supply unit that supplies the protective layer forming base material 8 having the same structure as that of FIG. 1 at a predetermined speed.
[0037]
The ink ribbon 37 has one end wound around a delivery shaft 38 and the other end wound around a winding shaft 39. At least one of the sending shaft 38 and the winding shaft 39 can be independently driven in both forward and reverse directions. An intermediate portion of the ink ribbon 37 sent from the sending shaft 8 is stretched over the guide shafts 21 and 22.
[0038]
The transfer section 4 includes a heat roller 26 as a transfer roller, a backup roller 27 disposed opposite to the heat roller 26, and the like. Between the heat roller 26 and the backup roller 27, a protective layer forming base material 8 functioning as an intermediate transfer medium is interposed.
[0039]
One end of the protective layer forming base material 8 is wound around a delivery shaft 29 provided on the upper side of the printing section 33, and the other end side is wound on a winding shaft 31 provided on the lower side of the printing section 33. I have. At least one of the sending shaft 29 and the winding shaft 31 can be independently driven in both forward and reverse directions. The sending shaft 29 and the winding shaft 31 function as a supply unit that supplies the protective layer forming base material 8 to the printing unit 33. The middle part of the protective layer forming base material 8 sent out from the sending shaft 30 is stretched over a guide shaft and is also stretched over a tension roller 32 to maintain a substantially constant tension.
[0040]
Further, the transfer section 34 includes a first transport roller pair 43A and a second transport roller pair 43B. The first transport roller pair 43A is disposed upstream of the heat roller 26 in the transport direction. Further, the second transport roller pair 43B is arranged downstream of the heat roller 26 in the transport direction.
[0041]
The first and second transport roller pairs 43A and 43B transport the transfer-receiving material disposed at a predetermined interval to a predetermined transfer position by the heat roller 26 along the transport path. That is, the first and second transport roller pairs 43 </ b> A and 43 </ b> B transport the transfer material 5 such that the transfer start position on the transfer material matches the transfer position by the heat roller 26.
[0042]
The heat roller 26 has a substantially semicircular cross section in a plane perpendicular to the rotation axis. Further, a part of the outer peripheral surface has a cut surface 26B cut in a planar shape. The length of the surface 26A along the circumferential direction of the arc portion, that is, the pressure-bonded surface length is formed to be substantially equal to or slightly longer than the length of the material to be transferred.
[0043]
The heat roller 26 is disposed so as to face the cut path substantially parallel to the conveyance path during the printing standby. As a result, a gap is formed between the heat roller 26 and the backup roller 27 in which the transfer target material 5 can be arranged. At this time, it is desirable that the protective layer forming base material 8 be disposed at a position where it does not contact the heat roller 26 and the backup roller 27 and does not contact the surface of the transfer material 5 that enters at the start of printing.
[0044]
In the above-described apparatus, the image layer 3 and the resin layer 4 are formed on the protective layer forming base material 8 using the ink ribbon 37 in the printing unit 33 to obtain a protective layer transfer ribbon similar to the protective layer transfer ribbon 10 in FIG. . Subsequently, in the transfer section 34, the printed material is obtained by transferring the protective layer 2 together with the image layer 3 onto the material 5 to be transferred from the protective layer transfer ribbon.
[0045]
FIG. 8 is a front view illustrating an example of a configuration of an ink ribbon used in the above-described apparatus.
[0046]
As shown in the figure, the ink ribbon 37 has a rectangular yellow ink layer 11, a magenta ink layer 12, a cyan ink layer 13, and a transfer prevention resin layer 14 having a predetermined size on a belt-shaped support sheet 15. It has a configuration formed in order.

Next, a transfer prevention resin layer was produced by the method described below.
[0081]
First, a paint having the following composition was prepared, and the paint was applied to one main surface of a support made of a polyethylene terephthalate film having a thickness of 6 μm. This was heated and dried at 140 ° C. for 1 minute to obtain a resin layer having a thickness of about 1 μm. As described above, a resin layer forming ribbon was produced.
[0082]
Composition of transfer prevention resin layer paint
5.0 parts by weight of silicone resin (GE Toshiba Silicone Co., Ltd. Tosgard 510)
47.5 parts by weight of toluene
47.5 parts by weight of methyl ethyl ketone
After an image is recorded on the protective layer forming layer, the resin layer of the resin layer forming ribbon is overlapped so as to be opposed to the resin layer forming ribbon. By peeling the body, the resin layer was thermally transferred to obtain a protective layer transfer ribbon according to the present invention.
[0083]
Next, a protective layer transfer ribbon and a PPC sheet as a material to be transferred were overlapped with an image interposed therebetween, introduced between a heat roller and a backup roller, and subjected to pressure and heating. At this time, the support of the protective layer transfer ribbon was arranged on the heat roller side, and the transfer material was arranged on the backup roller side. The length of the pressure contact surface of the heat roller was longer than the transfer length of the material to be transferred. In this transfer, the heating temperature was 170 ° C. and the pressure was 9 kgf / m 2 (about 8.8 × 105 Pa).
[0084]
Thereafter, the support was peeled from the protective layer transfer ribbon to obtain a printed material.
[0085]
The printed matter obtained in this way was free of burrs and creases and had good appearance. Further, no adhesion of the resin layer was observed on the backup roller after the thermal transfer. Further, although the protective layer was formed in the image area of the printed matter, a part of the non-image area outside the image area had a part where the protective layer was not formed.
[0086]
Comparative Example 1
After forming the image, a printed matter was obtained in the same manner as in Example 1 except that the thermal transfer of the resin layer was not performed.
[0087]
Comparative Example 2
Except that the pressure length of the heat roller was shorter than the length of the material to be transferred, all were the same as Comparative Example 1.
[0088]
In the obtained printed material, a material to be transferred was creased and the appearance was remarkably impaired.

Example 2
On one main surface of the support, instead of the transfer-preventive resin layer paint, the first transfer-preventive resin layer paint and the second transfer-preventive resin layer paint having the following composition were used, and the resin layers of 1 μm and 1 μm were sequentially formed. A resin layer forming ribbon was prepared in the same manner as in Example 1 except for the preparation, and a printed material was obtained in the same manner.
[0090]
Composition of first transfer prevention resin layer paint
5.0 parts by weight of silicone resin (GE Toshiba Silicone Co., Ltd. Tosgart 510)
47.5 parts by weight of toluene
47.5 parts by weight of methyl ethyl ketone
Composition of second transfer prevention resin layer paint
5.0 parts by weight of polyester resin (Toyobo Co., Ltd. Byron 240)
76.0 parts by weight of toluene
19.0 parts by weight of methyl ethyl ketone
The printed matter obtained in this manner had good appearance without occurrence of burrs, creases and the like. Further, no adhesion of the resin layer was observed on the backup roller after the thermal transfer. Further, although the protective layer was formed in the image area of the printed matter, a part of the non-image area outside the image area had a part where the protective layer was not formed.

【The invention's effect】
As described above, when the present invention is used, regardless of the thickness, hardness, etc. of the material to be transferred, without forming burrs at the time of forming the protective layer, unnecessary adhesion of the resin to the backup member is prevented, and the appearance is improved. It is possible to easily create a printed matter that is easy to tamper with and that is easy to falsify.
