2. Description of the Related Art In recent years, the sale of products and transactions such as auctions have been actively carried out on the Internet, and images are often dealt with among them, and the copyrights, moral rights, portrait rights, etc. of the images have become common. The problems involved are increasing. In an effort to solve the above-mentioned problems, a visible or invisible identification mark or the like is attached on or in the image etc. to record bibliographic items such as ownership, origin, credibility, copy prohibition, order acceptance, etc. There are many proposals to confirm. As a result, the effect of restraining and suppressing others who illegally use or abuse the image or the like is added. In the case of a visible mark, a proof that can be seen with the naked eye and cannot be hidden can be shown, and the proof can be clearly shown to others, which has a powerful effect. However, such a visible mark has a problem that it can be easily erased and counterfeited, and in recent years, various methods have been proposed in which an invisible mark is widely used instead of the visible mark, and the development of the invisible mark is also promoted. Efforts are being made. In many proposals of such invisible marks, those using digital information that has been developed in recent years are mainstream, and for example, Japanese Patent Laid-Open No. 10-191.
No. 017 publication, one utilizing a difference in luminance, one superimposing a specific dot pattern on an image, etc., and having a dot pattern or dot digital information exist on an image in a specific method or rule, and the specific method or rule. Those that can be read only by, those that are recorded in or on the image by special encryption and invisible by changing the specific method and rules, and illegal use of the image,
Examples include a device that makes it easy to identify the device when copying.

[0003]

Problems such as those known in the prior art such as ownership, origin, credibility, prohibition of copying, order acceptance, etc. by attaching a visible or invisible identification mark on or in such an image etc. The prescription that establishes records of bibliographic items is that most of the prescription is given to paper and the like, and the surface of a thin leaf body composed of one or more selected from artificial leather and leather as the main material in the present invention. The adhesiveness of the coloring material such as ink for imparting dots (dots) at the time of applying the digital signal is significantly different from that of paper, and the impartation and durability as set by the digital signal are poor It is an extremely defective one. The conventional identification mark imparted by such a digital signal does not cause any particular problem at the time of signal generation, but when the signal is applied to leather or the like, an accurate digital signal is not imparted due to its surface property and is regarded as a signal. There will be many problems in reliability reading inaccuracy and so on.

In addition, in the conventional method of giving an identification mark by such a digital signal, the dropping of the symbol due to washing is not taken into consideration at all, and when it is applied to a colored product as in the present invention, the digital signal is used. The applied identification symbol may disappear due to washing, and repeated identification and recognition may become impossible.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the problems of the prior art, that is, an accurate digital signal is not given due to the surface property and the reliability as an identification symbol is lacking, and disappears by washing and repeats. That is, the present invention solves the problem that identification and recognition are impossible, that is, the present invention is a colored product in which at least a predetermined color, an image, and a character are colored, and the colored product is selected from artificial leather and leather. It is a thin leaf consisting of one or more types of digital watermarks, and is internally dyed with a digital watermark code that is an invisible digital symbol, and is a digital watermark code intrinsic colored product characterized by being labeled with the digital watermark code. The above-mentioned digital watermark code in-carrying in which predetermined colors / images / characters are colored and / or the digital watermark code is formed by a digital print which is a set of halftone dots Ones and is a furthermore the electronic watermark code inherent coloration of watermark code inherent coloring matter is a label tag.

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, artificial leather and leather used in the present invention are not particularly limited. For example, a non-woven fabric, a woven fabric, a knitted fabric or the like is coated with a polymer material such as urethane resin. Or those given a leather-like shape by surface treatment or internal treatment of a polymer material such as urethane resin, cowhide, pig skin, other animal leather, and also on these leather surfaces, for example, non-woven fabrics or fabrics, Examples of base materials such as knits include urethane-based thin sheets.

The colorant inherent in the digital watermark code in the present invention may be clothes made of one or more materials selected from artificial leather and leather as described above, miscellaneous goods, and small thin leaflets such as tags. However, the form of these leathers or artificial leather products is not limited. Among these product forms, the tag used as a label is a more preferred form.

In the present invention, one or more thin leaves selected from artificial leather and leather of a predetermined color / image may be colored by front coloring as a single color on the thin leaves, or different colors may be used. May be front-colored as a plurality of colors on the thin leaflet, and these single or multiple colors are
The thin sheet may be partially colored only at predetermined positions, or a so-called digital print in which photographs, paintings, characters, etc. are digitized and reproduced on the thin sheet.
For coloring predetermined colors, images and characters on the thin leaf body, known coloring techniques such as dip dyeing, printing, transfer printing and inkjet method dyeing can be used. Preferably, for the purpose of the present invention including the case where a digital watermark code is formed as a digital symbol on the thin leaf body, a method of coloring with a digital signal such as an ink jet method to form a digital symbol (hereinafter referred to as digital printing) Is mentioned. Coloring with a more preferable inkjet method in digital printing means that it is not limited to one of various inkjet methods such as a thermal inkjet method, a piezo inkjet method, a bipolar deflection method, and a multi-deflection method. Coloring is performed by an inkjet method that is appropriately selected and adopted, and a specific pattern may be colored (printed) on the thin leaves by the inkjet method (direct inkjet printing method). The predetermined surface of the thin leaf may be colored by a method of transferring and coloring with a pattern paper obtained by the method (inkjet transfer method).

The invisible code in the present invention is a symbol (code) formed separately for colors and images on one or more thin leaves selected from artificial leather and leather, and is invisible in a strict sense. Rather than saying that it is something that is not perceived as an image by humans, and strictly speaking as an image even if it exists in a microscopic form on one or more thin leaves selected from artificial leather and leather. It is a sign (encryption) if it is buried in a color or color, and its microscopic shape (for example, one of the halftone dots) is for a given color / image on one or more thin leaf bodies selected from artificial leather and leather. Anything (code) that is difficult for humans to recognize as colors, images, and characters when viewed with the naked eye is acceptable. For example, artificial leather for decoration purposes, such as barcodes, or those that have no meaning as colors, images, or characters on one or more thin leaves selected from leather, but are recognized as images by the human eye. Is not an invisible code in the present invention, on the contrary, even if it is recognized as one of the halftone dots when observed with a magnifying glass, artificial leather, the entire color / image on one or more thin leaves selected from leather From the perspective of things that do not disturb it, things that are just hidden halftone dots are included in the invisible code, and things that are invisible to the naked eye and can be detected as a signal are naturally included in this invisible code. Is. The invisible code in the present invention may be the one described above, but is preferably an invisible code formed by digital printing.

The material used for imparting the invisible code print or the like in the present invention is not particularly limited as long as it corresponds to the invisible code described above, but preferred examples are selected from artificial leather and leather. Colored bodies (dye, pigment, etc.) used for colors, images, and characters formed on one or more thin leaf bodies and hue and / or saturation are different, and the difference between them is, for example, an optically detectable colored body. There are those with different internal reflection wavelength peaks of these colored bodies, and among them there are fluorescent dyes and pigments, UV-excited dyes and pigments, and further infrared and near-infrared absorber reflectors, magnetic powders. Examples include a body and a conductive powder. These, invisible code forming material, for example, if necessary, dissolved or dispersed in a liquid medium such as a binder or vehicle and water, a solvent, etc., and this colored body medium without a colored body medium,
An invisible code is formed on one or more thin leaf bodies selected from artificial leather and leather by means such as printing or coating. The formation of the invisible code is not particularly limited as a means, but a method of forming by a digital print such as an inkjet method is preferable.

Although not limited to the above-mentioned examples of preferable materials, any material that can form an invisible cord in accordance with the spirit of the present invention can be used in the present invention. For example, artificial leather,
Using the same material as the coloring body (dye, pigment, etc.) used to form colors, images and characters on one or more thin leaf materials selected from leather, it is encrypted at the time of formation and used for decoration. It may be formed as a latent image on the formed color or image. In the present invention, artificial leather colored with the above-mentioned colors / images, coloring in one or more thin leaf colorants selected from leather, both the colors / images and characters and the invisible code are digitally printed. It is preferable that at least one of coloring, coloring of images and characters, and formation of an invisible code is formed by digital printing. These invisible code forming materials have at least wash resistance that is equal to or more than the coloring used for decorative colors and images and letters formed on at least one kind of thin leather selected from artificial leather and leather. , Abrasion resistance, and sun fastness are required. These invisible codes in the present invention, artificial leather, may be formed at any position of one or more thin leaves selected from leather, for the detection and reading of the invisible code, It is preferable to limit the formation to a specific portion of one or more thin leaf bodies selected from artificial leather and leather.

Since the invisible code is detected or read, since it is formed on a specific surface unevenness because the code is one or more thin leaves selected from artificial leather and leather, especially in the case of digital signals, artificial leather is used. , When the signal before being formed on one or more thin leaves selected from leather and the symbol used for detection are not always the same signal / symbol and it is difficult to detect without correction or correction processing There are many
This can be achieved by correcting or correcting the symbol read (detected) at the time of detection and returning it to the original signal. Software or the like for correcting or correcting this symbol is not particularly limited, and may be appropriately selected and used depending on the invisible code material used and the method of the invisible code. This artificial leather, encrypted signal because it is one or more thin leaves selected from leather
On the contrary, the problem due to the sparseness of symbols has an effect of helping to solve an annoying obstacle such as an invisible code (encrypted symbol). In the present invention, at least a predetermined color / image is colored artificial leather, which is a colored material of one or more thin leaves selected from leather, wherein the colored material has an electronic watermark code which is invisible digital information, and The form of the colorant inherent in the digital watermark code, which is characterized by being marked with a digital watermark code, is not particularly limited, but it is a sign attached to clothing or miscellaneous goods as an identification material and used for branding or quality marking. A tag is mentioned as a preferable example.

Examples are shown below, but the present invention is not limited thereto. * Example 1 "Black logo and a full-length color image of a Shepherd dog are separated on the pocket part of the body part of the M size jumper made of artificial leather coated with polyester urethane resin on polyester fiber fabric. Characters and images were formed using an inkjet print thermal transfer means. On the whole-body image of the shepherd dog of the transferred characters and images, the average CMY value of the whole-body image is increased by a specific value to increase the average value on one scanning line by 1 signal.
The symbol "U @ M" is added so that 0 pixel becomes 1 and the signal is used to print on a transfer paper by using a specific polyester disperse dye by inkjet printing. Text and image with "English logo and full-length figure of Shepherd dog are separated" in the pocket part of the trunk part of the M size jumper made of artificial leather prepared by copying "U @
M ”was formed, and a transparent polyurethane resin was coated on the formed image. The encrypted symbol "U @ M" is almost a color and does not appear as an image and is difficult to recognize with the naked eye.
The characters and images as "colors and images, where the logo in English letters and the full-length image of the Shepherd dog are separated" were reproduced in extremely fine detail. This encrypted symbol "U @ M"
Was able to accurately reproduce the symbol "U @ M" by detecting it with an optical detecting means. The digitally printed artificial leather M size jumper has a torso region with pockets on the torso region, with a "English logo and a full-length figure of a Shepherd dog separated" characters and image, and an encrypted symbol "U".
I tested the resistance to washing by doing home laundry treatment 5 times with "@M" formed, but the decoration of "the logo in English letters and the full-length image of the shepherd dog are different" as colors and images The readability of the cryptographic symbol as the latent image and the latent image did not change either. This latent code "U @ M" was effective in preventing forgery by a third party and confirming authenticity.

* Example 2 Using pig skin, this plain pig skin dyed in light brown was pressed with a dark brown letter "U @ M" by a heat method to form a large number of 3 cm x 8 cm rectangles. 1cm x 3 at the center of each
A recess is formed with a size of cm, and the encrypted symbol is digitally printed (inkjet print) in yellow at a position 3 mm below the letter "U @ M" formed in the center of the rectangle so as to follow the symbol. Formed. The encrypted digital signal was “200112UM”, which was processed in the same manner as in Example 1 so that it could be detected, and the formation was performed by a direct inkjet printing method unlike in Example 1. 3 cm x 8 cm with a large number of the same characters and ciphers obtained by coating the transparent character of "U @ M" and the encrypted digital signal of "200112UM" with transparent polyurethane resin. A rectangular tag was cut to produce a tag tag for clothes. The encrypted symbol “200112UM” is a color that is hardly visible as an image and is difficult to recognize with the naked eye, and only the dark brown character “U @ M” as a sign and the light brown color of the ground are recognized. It was Encrypted symbol "200112UM"
Is a symbol “20011” when detected by an optical detection means.
2UM "could be reproduced correctly. This latent code "200112UM" was effective for preventing forgery by a third party and confirming the authentic product.

* Example 3 Using pig skin, this plain pig skin dyed in light brown was embroidered with dark green letters "U @ M" for each of a number of 3 cm x 8 cm rectangles and 1 cm x in the center thereof. Formed with a size of 3 cm,
Below the letter "U @ M" formed in the center of this rectangle 3
An encrypted symbol was formed at a position mm along the symbol by digital printing (ink jet printing) so as to be dark brown. The encrypted digital signal is "2001
12UM12 ”, which was processed in the same manner as in Example 1 so that it could be detected, and the formation was performed by an inkjet print transfer system, unlike in Example 1. This manifest "U @ M" and the encrypted digital signal are "200112".
UM12 "was formed on the surface, and a transparent polyurethane-based resin was coated on the UM12" to cut a 3 cm × 8 cm rectangle on which a large number of the same embroidery and codes were printed, and a marker tag for clothes was manufactured. Encrypted symbol "2001
"12UM12" is almost invisible as an image and hardly visible to the naked eye, and the green character "U @" is a sign.
Only "M" and the ground color light brown were recognized. The encrypted symbol "200112UM12" is detected by the optical detecting means to obtain the symbol "200112UM12".
Was able to be reproduced accurately. The symbol "200112UM12" as the latent image was effective for preventing forgery by a third party and for confirming the genuine product.
