Description

Ink ribbon for thermal transfer printing and anti-counterfeiting and method for manufacturing the same}

The present invention relates to an ink ribbon for thermal transfer printing and a method of manufacturing the same for preventing forgery. In detail, by including a separate receiving layer (receptive layer), the transfer of letters, figures and images with a colored ink layer ribbon, even after superimposing the security ink layer ribbon that emits under a special light source for forming a security image excellent sensitivity The present invention provides an ink ribbon and a method of manufacturing the same for thermal transfer printing for preventing forgery, which can provide a forgery and tamper resistant printed material having enhanced durability and clarity.

The thermal transfer recording method decomposes the color image reproduced by the electric signal, and separates it into the additive mixture of red, red, green, and blue, which are three primary colors of light. R, G, and B are converted into subtractive mixtures of yellow (Yellow, Y), magenta (Magenta, M), and cyan (Cyan, C), which are three primary colors of color, and are transmitted to the printer. At this time, the calorific value corresponding to the image signal of yellow, magenta, and cyan, respectively, is converted and transferred to the heat generating head of the thermal transfer printer, and then transferred to the printing paper through the thermal transfer ribbon, and the yellow, magenta, and cyan dyes are used. Natural image printing is possible by mixing. This thermal transfer recording method is mainly used for issuance of identification cards that require security because of the advantage of instantaneous production of color images.

Recently, in various fields, cards, ID cards, passports, etc., which require security, are used to authenticate an individual's identity, and the cards for identification of such individuals are colorless and transparent in visible light to prevent forgery and tampering. Although not visible, a method of forming a security image by printing using a fluorescent dye that emits visible color when irradiated with ultraviolet light or a method of determining authenticity by performing special embossing such as hologram has been proposed.

For example, Japanese Patent Application Laid-Open No. 2000-225774 (August 15, 2000) discloses an anti-counterfeiting thermal transfer protective ribbon in which Y, M, C color material layers and R, G, B color material layers are formed.

 However, yellow, magenta, and cyan color characters or images are transferred onto a transfer object such as a card or paper, and invisible dyes having red, green, and blue colors that have invisible light conversion characteristics are already printed when superimposed. Color dyes saturate the dye-receiving layer on the transfer material, reducing the amount of transfer of the invisible dye transferred to the back, reducing the chromaticity of the printed matter, and also transferring the transferred color dye layer toward the invisible dye ribbon to achieve a complete image. There is a problem that can not be.

On the other hand, in order to ensure smooth transferability during printing, the surface energy of the ink ribbon should be small. After the dyes and pigments are laminated, the surface energy of the ink ribbon is lower than the surface to be transferred first, and the receiving layer on the surface of the transfer member Since it is saturated with the colored dye, there is a problem that the transferability of the security ink layer ribbon including the invisible dye to be transferred later is considerably lowered.

In order to solve the above problem, the inventors of the present invention, unlike the conventional thermal transfer ink ribbon is formed of a colored ink layer ribbon and a security ink layer ribbon, to protect the pre-printed image therebetween and the image to be printed after It is to provide a method of manufacturing an ink ribbon for thermal transfer printing for anti-counterfeiting that includes a receiving layer that can accommodate more.

In addition, by providing the manufacturing method, when printing a color character and image, and the like to form a security image for preventing forgery, the amount of invisible dye transfer is increased, and the reverse transition phenomenon of the transferred color dye can be improved and prevented. It has been found that it is possible to provide a new ink ribbon for thermal transfer printing for anti-counterfeiting, which includes security-enhanced anti-counterfeiting and tamper-proof functions having excellent durability, sensitivity, and clarity.

Examples 5 and 6 include the receiving layer, and it can be seen that the infrared sensitivity is significantly increased compared to Comparative Examples 3 and 4 without the receiving layer.

That is, the thermal transfer printing ink ribbon for anti-counterfeiting according to the present invention further includes an additional receiving layer as compared to the thermal transfer ink ribbon according to the prior art, even though the security ink layer for anti-counterfeiting and tampering is overprinted.
