2. Description of the Related Art In this type of intermediate transfer recording medium, an image is recorded on a receiving layer by a thermal transfer recording method using a thermal transfer sheet provided with a color material layer. A high quality image can be formed. In addition, since this intermediate transfer recording medium can be used as a receiving layer having excellent adhesiveness to the transferred material, or by interposing the adhesive layer, the receiving layer can be transferred to the transferred material with good adhesiveness. It is preferably used for a transferred material that is difficult to transfer a color material and cannot directly form a high-quality image, or a transferred material that is easily fused with a coloring material layer during thermal transfer.

FIG. 10 is a sectional view schematically showing an example of an intermediate transfer recording medium. The intermediate transfer recording medium 101 is
The base film 102 and the transfer portion 112 having at least the receiving layer 105 are included. Receptive layer 105
The image 106 is formed by thermal transfer using a thermal transfer sheet provided with a color material layer. Transfer part 11
After the image 106 is formed on the receiving layer 105, No. 2 is peeled from the base material film 102 and transferred onto the transfer target, and the target image 106 is formed on the transfer target.

This intermediate transfer recording medium can transfer and form a high-resolution and high-quality image on a transfer-receiving member. In addition, in this intermediate transfer recording medium, necessary items such as a signature are previously written or printed on the transfer target material, and then the transfer portion on which an image such as a character or a photograph is formed is transferred. You can also create prints. Therefore, this intermediate transfer recording medium can be preferably used for the production of identification documents such as passports and prints such as credit cards and ID cards.

The printed matter such as the passport and the credit card described above is required to have security, that is, high reliability and safety that is difficult to be forged or tampered with. Therefore, various measures have been taken to make it difficult to forge or falsify by copying.

For example, in order to prevent forgery and falsification of a printed matter, an intermediate transfer recording medium has been proposed in which a hologram pattern, micro characters, etc. are provided in a transfer section, and the hologram pattern and the micro pattern provided in the transfer section are proposed. Character
It has been proposed to prevent forgery and falsification of images such as characters and face photographs formed on a printed matter by transferring them to a transfer target together with the images.

However, the intermediate transfer recording medium of this proposal is
A joint at the time of plate-making the hologram pattern, that is, a joint at which the hologram pattern is interrupted appears between the hologram patterns at the time of making the hologram pattern in sequence, at regular intervals. Then, since the image was formed on the receiving layer of the intermediate transfer recording medium without consideration for avoiding the joint of the hologram pattern, an image may be formed on the joint of the hologram pattern. . Since the joints of hologram patterns appear on the image, the printed matter has a reduced commercial value and is not particularly preferable in the case of a printed matter requiring high reliability and safety such as a passport.

To solve this problem, Japanese Patent Laid-Open No. 11-
No. 254844 forms a hologram mark for setting an image formation position for each formed hologram pattern, and detects the hologram mark,
It is proposed to prevent an image from being formed on the joint of the hologram pattern.

[0009]

However, JP-A-11-
No. 254844 has hologram marks (position detection marks) corresponding to the patterns to be transferred, but when different patterns are transferred to the front and back of the card, etc., distinguish each pattern. I couldn't. In particular, when the intermediate transfer recording medium wound in a small roll is used from the middle, the pattern corresponding to the front and back cannot be detected,
There was a possibility that the order of transcription would be incorrect.

An object of the present invention is to provide an intermediate transfer medium capable of distinguishing different patterns even when different patterns are transferred at the transfer section.

[0011]

In order to solve the above-mentioned problems, the invention of claim 1 comprises a base film and a receptive layer releasably provided on the base film and on which an image is formed. A transfer portion formed, and an intermediate transfer recording medium in which an image is formed on the receiving layer of the transfer portion and then the image is transferred to a transfer target.

The intermediate transfer recording medium 1A is composed of a base film 2 and a transfer section 12 provided on the base film 2 in a peelable manner. The transfer part 12 has at least the receiving layer 5 on which an image is formed, and the release layer 3, the protective layer 4, the hologram layer 7, the transparent vapor deposition layer 8, the anchor layer 9, and the receiving layer 5 in this order from the side of the base film 2. Are stacked in.

On this hologram layer 7, as shown in FIG. 2 described later, a plurality of different hologram patterns 21 (2
1A, 21B) and their hologram patterns 21
A plurality of different hologram marks 22 (22A, 22B) provided for each (21A, 21B) are formed. In addition, the transfer portion 12 can also be formed with a micro character and a color pattern. This intermediate transfer recording medium 1A
Is used to transfer the transfer portion 12 after the image 6 is formed onto the transfer target to obtain a printed matter.

Layers other than the receiving layer 5 and the hologram layer 7 provided in the transfer section 12, for example, the peeling layer 3, the protective layer 4,
The anchor layer 9 is not necessarily an indispensable layer and is appropriately selected and provided depending on the material of the transferred material, the use and usage of the printed matter, and is not particularly limited. Therefore, instead of these layers, or in addition to these layers, a layer having a specific action such as an ultraviolet absorbing layer can be appropriately selected and provided. The transparent vapor deposition layer 8 and the anchor layer 9 are usually provided together with the hologram layer 7.

FIG. 2 is a plan view showing the intermediate transfer recording medium according to the present embodiment. The intermediate transfer recording medium 1B has two different types of hologram patterns 21A and 21B and two different hologram patterns 21 provided for each of the hologram patterns 21.
The hologram marks 22A and 22B of a kind are formed on the hologram layer 7 in a fixed relative positional relationship. In this embodiment, the hologram patterns 21A and 21B are
A pattern for the surface of the card that is the transfer target to be described later,
Two different types of patterns corresponding to the pattern for the back surface are formed. In addition, the hologram marks 22A, 22
B has two types of position detection marks of different lengths provided corresponding to the hologram patterns 21A and 21B.

The hologram pattern 21 is provided in order to improve the decorative property of the finally formed print, or to prevent forgery or falsification because it is difficult to copy, and in particular, a passport or the like. It is preferably used when the printed matter is required to have high reliability and safety.

The size and shape of the hologram pattern 21 differ depending on the mode of the printed matter required, and are not particularly limited. As a method for forming the hologram pattern 21, a conventionally known method, for example,
Fine relief is formed by embossing using an original plate provided with a relief pattern of hologram interference fringes.

The hologram mark 22 is formed in the same process as the formation of the hologram pattern 21.
Simultaneously with the formation of, the hologram patterns 21 are formed with a fixed relative positional relationship.

The hologram mark 22 can be used for the following purposes. (1) A mark for setting an image forming position by a thermal transfer method using a thermal transfer sheet on the receiving layer 5 at a predetermined position where the hologram pattern 21 is provided, (2) Intermediate transfer after the image is formed A mark for setting a transfer position of the adhesive layer having excellent adhesiveness to the receiving layer and the transfer target at a predetermined position of the transfer portion 12 of the recording medium, (3) A mark for setting the position of the transfer part to which the transfer body is transferred, or (4) a colored detection mark on the receiving layer 5 of the transfer part 12 before the image is formed by the thermal transfer method using a thermal transfer sheet. The mark used to set the position for forming the.

The hologram mark 22 may be provided at any position, and its size and shape are not particularly limited. Since the method for forming the hologram mark 22 is the same as the method for forming the hologram pattern 21, these can be formed simultaneously by the same plate making, which is efficient.

It can be stopped.

The size and shape of the end mark 33 is not particularly limited, but it must be provided so that it can be distinguished from the diffracted light or scattered light from the hologram mark 22. For example, by making the end mark 33 longer than the hologram mark 22 along the longitudinal direction of the continuous sheet 31, it can be distinguished from the diffracted light or scattered light from the hologram mark 22.

The end mark 33 may be any one as long as it produces scattered light. For example, a matte-treated aluminum foil or PET (polyethylene terephthalate) film, a porous PET film, sticking of a seal or the like, or mark printing. And the like.

The end mark 33 is replaced by the hologram mark 2
It is preferable to form it by a hologram as in the case of 2, and it is efficient because it can be formed by a method such as labeling of a hologram sticker.

FIG. 4 is a perspective view showing a mode of detecting a hologram mark and an end mark provided on the intermediate transfer recording medium. The light emitted from the light emitting element 51 is recorded on the intermediate transfer recording medium 1D as hologram patterns 21A and 21A.
The hologram marks 22A and 22B provided for each B diffusely reflect and emit diffracted light 53. By detecting the diffracted light 53 with the light receiving element 52, the positions of the hologram marks 22A and 22B are detected. End mark 3

The light emitting element 51 is usually a semiconductor laser,
Although an LED or the like is used, it is not particularly limited as long as it has the same function. A photo sensor or the like is usually used as the light receiving element 52, but the light receiving element 52 is not particularly limited as long as it has the same function. The method of detecting the mark may be transmitted light or reflected light.

First, the above-mentioned intermediate transfer recording medium 1A and a thermal transfer sheet provided with a color material transfer portion are prepared, and are pressed between a heating device such as a thermal head and a platen roll, and the heating device of the heating device is selected according to image information. The heat generating portion is selectively caused to generate heat, and the color material of the color material transfer portion on the thermal transfer sheet is transferred to the intermediate transfer recording medium 1A.
The image 6 is recorded by transferring it to the receiving layer 5 of.

As the thermal transfer sheet, any conventionally known one can be used. In the color material transfer portion provided on the heat transfer sheet, a color material layer is formed with a heat-meltable ink or a sublimation dye. The color material layer provided in the color material transfer section is appropriately selected from the heat-fusible ink and the sublimation dye according to the intended printed matter, and is provided in the frame order. The coloring material transfer portion composed of a sublimation type dye used for obtaining a printed matter having excellent gradation is a sublimation dye such as yellow, magenta, cyan or black which is usually used, if necessary. , Are provided in a frame sequential manner.

Further, by providing the adhesive layer in the surface order with the color material transfer portion, the adhesive layer can be subsequently transferred onto the receiving layer 5 to which the color material has been transferred. As a result, it is possible to improve the adhesive force between the transfer section 12 and the transfer target 16 when the transfer section 12 of the intermediate transfer recording medium 1A is transferred to the transfer target 16, and the transfer process of the adhesive layer can be performed in color. This is efficient because it can be performed at the same time as the image forming step by transferring the material.

The position where the image is to be formed on the intermediate transfer recording medium is set by detecting the hologram mark 22 provided on the transfer section 12. Then, the color material is transferred from the color material transfer portion of the thermal transfer sheet to the set position to form an image.

In the intermediate transfer recording medium of this embodiment, hologram patterns 21A and 21B are provided in advance, and in the positional relationship with the hologram patterns 21A and 21B, as shown in FIG. 6A and 6B need to be formed.

The position of the part 12 is set. Then, the transfer portion 12 at the set position is transferred onto the transfer-receiving member 16 to form the printed matter 17.

For example, when the transfer target 16 is an ID card 81 as shown in FIG. 6, the transfer portion 12 to be transferred to a predetermined position on the front surface 81A and the back surface 81B of the ID card 81 can be accurately measured. For transfer, by detecting the hologram marks 22A and 22B provided on the intermediate transfer recording medium, the position of the transfer portion 12 to be transferred is accurately set.

The transfer portions 12 to be transferred from the intermediate transfer recording medium are transferred to the obtained prints 17A and 17B at predetermined positions on the surfaces 81A and 81B to be transferred. For this reason, the positional relationship between the image previously formed on the ID card 81 and the image provided on the transfer target by the transfer of the transfer portion 12 becomes accurate.

Titanium oxide having a thickness of 500Å is formed as a transparent vapor deposition layer 8 on the upper surface by a vacuum vapor deposition method, and the following receiving layer coating liquid is applied and dried on the transparent vapor deposition layer 8 to obtain a thickness of 2 The receiving layer 5 having a thickness of 0.0 μm is formed, and the hologram mark 22
An intermediate transfer recording medium of Example 1 provided with was prepared.

Coating liquid for receiving layer; 40 parts by weight of vinyl chloride-vinyl acetate copolymer Acrylic silicone 1.5 parts by weight Methyl ethyl ketone 50 parts by weight 50 parts by weight of toluene

The obtained intermediate transfer recording medium was slit into a predetermined width and then wound into a small roll to produce an intermediate transfer medium hologram ribbon. By using a thermal transfer sheet in which each color material layer of yellow, magenta, and cyan is provided on the receiving layer 5 in a surface sequential manner by a dedicated printer,
Two types of images 6A and 6B corresponding to the front and back of the D card 81
Was formed. The image forming position is the hologram mark 22.
The positions of A and 22B were detected and set by the semiconductor laser 51 and the photosensor 52.

The intermediate transfer recording medium 1C on which the image was formed on the receiving layer 5 was retransferred onto the ID card 81 by the heat roller unit, and the ID card 81 having the patterns 6A and 6B formed on the front and back sides thereof was obtained. Although the intermediate transfer recording medium (hologram ribbon) wound on the roll was once removed from the transfer machine on the way, and again loaded at an arbitrary position, the transfer was resumed.
The transfer was completed satisfactorily without any mistake in the front and back.

Example 2 Using the small-rolled intermediate transfer recording medium (hologram ribbon) obtained in Example 1 above,
On the receiving layer 5 of this intermediate transfer recording medium, using a thermal transfer sheet provided with a color material layer 78 for color detection marks and each color material layer of yellow, magenta, and cyan in a surface-sequential manner, first, by a thermal transfer method, a color detection mark is first formed. 62A and 62B were transferred and formed. The coloring material layer for the color detection mark is a heat-meltable black ink layer, and the formation positions of the color detection marks 62A, 62B are the hologram marks 22A, 22B provided on the hologram layer of the intermediate transfer recording medium 1E. It was detected and set in the same way as. Subsequently, the color materials of yellow, magenta, and cyan were successively transferred to form images 6A and 6B on the receiving layer 5 of the intermediate transfer recording medium 1E. The image forming position was set by detecting the colored detection marks 62A and 62B provided on the receiving layer 5 with a transmission sensor.

The results of Examples 1 and 2 were both favorable. Particularly, in the case of the hologram mark, the formation thereof was easy and the image forming position accuracy was excellent. Further, in the case of the colored detection mark, since a transmission type sensor can be used, it is easy to read.

Comparative Example 1 FIG. 8 is a diagram showing Comparative Example 1 of the intermediate transfer recording medium. When embossing the patterns 106A and 106B and the position detection mark (hologram mark) 122, the size of the hologram mark 122 was made the same 10 mm regardless of the patterns 106A and 106B. Using the intermediate transfer recording medium (hologram ribbon) 100 that was completed and wound in a roll shape, cards were printed on the front and back sides in the same manner as in Example 1. However, the front and back sides were copied in reverse depending on the loading position of the roll. Occasionally, the workability of issuing was extremely poor.

(Comparative Example 2) FIG. 9 is a diagram showing Comparative Example 2 of the intermediate transfer recording medium. Hologram pattern 221
An intermediate transfer recording medium 200 in which a hologram mark was not formed when forming was prepared. The detection mark 222 is printed on the receiving layer of the obtained intermediate transfer recording medium 200 by printing.
A, 222B was formed. Detection marks 222A, 222
B was provided to the patterns 206A and 206B with a length of 10 mm and 20 mm, respectively. Detection marks 222A, 2
The position of 22B was set by mechanical feeding so as to be the same as the pattern pitch of the hologram pattern 221.

Then, on the receiving layer of the intermediate transfer recording medium,
An image was formed by a thermal transfer method using a thermal transfer sheet in which yellow, magenta, and cyan color material layers were provided in a surface-sequential manner. The image forming position was set by detecting a detection mark provided by printing with a transmissive sensor. The finished card had a pattern transferred to the front and back, but the joints of the hologram pattern were transferred, resulting in a misaligned printed matter.

Further, since the detection mark by printing has to be printed in a separate process, it is complicated to form. As a result, the detection mark could not be provided with high accuracy, and the image forming position accuracy was poor.

[0083]

As described above, since a plurality of different position detection marks are provided depending on the intermediate transfer recording medium,
When transferring to multiple places such as the front and back of a card,
It is now possible to distinguish transfer positions such as the front and back. Also,
Even when the intermediate transfer recording medium wound in a small roll is used halfway, the transfer positions on the front and back surfaces can be detected, so that the transfer sequence is not erroneous.
