。(Prior art) Conventional 5 A highly concealable and highly safe verification printed material is made by arranging or laminating at least two or more types of ink layers of the same color tone with different near-infrared transmittances or reflectances. A printed matter has been proposed in which a printed matter is covered with an overcoat layer that transmits near infrared rays to hide it, and a printed layer that transmits near infrared rays is further formed on the surface of the overcoat layer (Japanese Patent Application Laid-Open No. 58-134782), such printed materials are highly safe because hidden patterns can be identified only by near-infrared rays of a specific wavelength, and there is less chance of counterfeiting or tampering. . but.
近赤外線の透過率または反射率が異なる同色調のインキ

Since the color tone must be matched to an ink with low near-infrared transmittance or reflectance, the color of the ink is limited by pigments that do not transmit or reflect light in the near-infrared region, and black, black,
It has the disadvantage that it is limited to cool and dark colors such as blue, green, brown, and ocher. Furthermore, even if a white overcoat layer was provided on top of the cold-colored hidden pattern, the underlying layer could not be sufficiently hidden, and the proposal to print any pattern on top of it was impractical.

The present invention provides information processing using a printing ink containing a near-infrared absorber that absorbs at a specific wavelength of 700 to 11,000 nm and, if necessary, a pigment. A recorded material printed in a shape corresponding to the wavelength is overcoated with an ink that has substantially no absorption at the specific wavelength and absorption or reflection in the visible region. It is a recorded matter that can be identified by near-infrared rays, and the near-infrared absorber has no substantial absorption in the wavelength range of 400 to 700 nm.

9 copies of the resulting base ink were printed solidly on a cellophane film (KM Celsy, manufactured by Daicel) using the gravure coating method, and then a barcode was printed using near-infrared absorbing ink, and then a barcode was printed on top of that using a near-infrared absorbing ink. I printed it solidly with overcoat ink so that all the codes were hidden. No barcode was visually observed in the resulting recorded material, but it was readable when scanned with a barcode reader with a reading wavelength of 780 mn.

を有する。(Operations and Effects of the Invention) According to the present invention, information is printed using colorless or light-colored near-infrared absorbing ink that exhibits almost no absorption in the visible range, and not only cool colors and dark colors but also warm colors, A recorded matter with a bright color overcoat can be obtained, so
Eliminates color restrictions in design. Furthermore, since it is difficult to visually determine the presence of information codes in the recorded material of the present invention, it is of course useful as a hidden code, and also has a tamper-proofing function.
更に、従来公知の近赤外線吸収検出装置が用いられる為
、識別の自動化が容易となる。Furthermore, since a conventionally known near-infrared absorption detection device is used, automation of identification becomes easy.
