DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the drawings. The temperature-sensitive printed material according to the present invention is characterized in that a temperature-sensitive ink layer is formed on at least a part of a concavo-convex portion E which is concavo-convex processed in synchronization with a printed image. Here, the print image encompasses all the symmetrical portions of printing, such as pictures, characters, and patterns. Concavo-convex processing is to provide a height difference partially different from the plane level with respect to the plane, and embossing from the back side of the base sheet is a general processing means, but it is pushed in from the front side A concave portion may be formed. Synchronization between the printed image and the concavo-convex processing means that the contour of the entire printed image, or a part of the printed image that is the point thereof, and the contour of the concavo-convex processed portion substantially match, and if necessary, the density gradation of the printed image Means that a relief-like height is provided according to. FIG. 1 is an explanatory diagram of a configuration of a print having temperature sensitivity according to the present invention. FIG. 1A is a schematic cross-sectional view illustrating a first embodiment of a temperature-sensitive printed material 10 according to the present invention. First

As shown in FIG. 1A, first, a print image is printed on a substrate 1 with a normal print ink, a print image ink layer 2 is provided, and a temperature-sensitive ink is applied so as to cover the entire print image. To form a temperature-sensitive ink layer 3 which has a hiding power at room temperature but changes transparently and reversibly at body temperature, and then prints or spot-coats an overprint varnish on the temperature-sensitive ink layer 3. To form a transparent protective layer 4,
Lastly, a concavo-convex processed portion E having a three-dimensional expression is formed by performing concavo-convex processing synchronized with the print image.
The formation of the protective layer 4 is particularly necessary in the case of an unstable water-based temperature-sensitive ink, but may be omitted in the case of a stable oil-based temperature-sensitive ink. FIG. 1B is a schematic cross-sectional view showing a second embodiment of the temperature-sensitive printed material 10 according to the present invention. As shown in FIG. 1 (b), the temperature-sensitive printed matter 10 according to the present invention showing the second aspect first comprises:
A part of the printed image is printed with a normal printing ink to form a printed image ink layer 2, and then the remaining part of the printed image is printed with a temperature-sensitive ink to reversibly obtain different colors at normal temperature and body temperature. A variable temperature-sensitive ink layer 3 is formed, a transparent protective layer 4 is provided thereon, and finally, a concavo-convex processing portion E having a three-dimensional expression is formed by performing concavo-convex processing synchronized with a printed image. is there. FIG. 1C is a schematic cross-sectional view showing a third embodiment of the print 10 having temperature sensitivity according to the present invention. As shown in FIG. 1 (c), the print 10 having temperature sensitivity according to the present invention showing the third aspect first forms a print image ink layer 2 by printing a print image with a normal printing ink. A part thereof forms a temperature-sensitive ink layer 3 which has a hiding power at room temperature but changes transparently and reversibly at body temperature, or a temperature-sensitive ink layer 3 which changes reversibly to different colors at room temperature and body temperature, respectively. A transparent protective layer 4 is formed thereon, and finally, a concavo-convex processed portion E having a three-dimensional expression is formed by performing concavo-convex processing synchronized with the printed image. As described above, the embodiments of the temperature-sensitive printed material 10 according to the present invention are basically the above three types. However, depending on the target print image, the purpose of use, and the like, the print image ink layer 3 and the temperature-sensitive ink layer 4 by appropriately changing the overlapping combination of the temperature-sensitive ink layers 4.
By forming, various aspects rich in variations can be produced.

The printing image ink layer 2, the temperature-sensitive ink layer 3, and the protective layer 4 may be formed by any known printing method. When concealing the underlay by the temperature-sensitive ink layer 3 and concealing the underlay by one-time printing with the temperature-sensitive ink, it is preferable to give the temperature-sensitive ink a dark color such as brown, deep blue, or black. In this case, the printing method is preferably a silk screen printing method capable of obtaining a thick ink film having a hiding power. When the temperature-sensitive ink density is not sufficient, solid printing or tint block printing may be performed a plurality of times. The protective layer 4 prevents blocking by the temperature-sensitive ink layer 3 and protects the temperature-sensitive ink layer 3 from physical destruction, chemical discoloration, and the like. Further, when an oil-based temperature-sensitive ink is used, it can be omitted.

The base material 1 may be any material such as paper, paperboard, plastic sheet, metal sheet, etc., as long as it has printability and suitability for unevenness processing. As an embossing method, embossing using an embossing die is performed on paper, paperboard, and a metal sheet, and embossing is performed on a plastic sheet which is liable to be thermoplastically deformed in advance so as to synchronize with a printed image. Sheet forming (vacuum / pressure molding method) using a formed molding die is preferably used.

According to the temperature-sensitive printed matter according to the present invention having the above-described structure, various print image changes can be brought about just by touching the concavo-convex portion E or a predetermined portion thereof. . FIG. 2 is an explanatory diagram of a change in one print image occurring in a temperature-sensitive printed matter according to the present invention. FIG. 2A shows the temperature-sensitive printed matter according to the present invention at room temperature (or room temperature).
FIG. 2B is an example of a print image, and FIG. 2B is a print image that changes with body temperature. In this case, the temperature-sensitive printed material 10 according to the present invention has a configuration as shown in FIG. 1 (a).
The print image is a simple print image as shown by oblique lines in FIG. A region surrounded by a dotted line surrounding the periphery indicates the uneven portion E. Therefore, at room temperature, the sketch is concealed by the specific dark-colored temperature-sensitive ink layer 3. However, when the irregularity-processed portion E is touched with a hand, the temperature-sensitive ink layer 3 becomes transparent at body temperature, and a sketch appears instantly as shown in FIG. The color of this sketch is free. That is, any print image can be printed. Then, after a while, when the temperature of the temperature-sensitive ink layer 3 decreases, the print image returns to the print image of FIG. Thus, the temperature-sensitive printed matter 10 according to the present invention is
Changes reversibly between the print image shown in FIG. 2A and the print image shown in FIG. 2B.

FIG. 3 is a diagram for explaining another change of a printed image which occurs in a temperature-sensitive printed matter according to the present invention. FIG. 3A is an example of a print image of a temperature-sensitive printed material according to the present invention at normal temperature, and FIG. 3B is a print image changed with body temperature. In this case, the temperature-sensitive printed material 10 according to the present invention has a configuration as shown in FIG. 1 (b), and the printed image in the concavo-convex processed portion E is printed with normal ink and temperature-sensitive ink separately. When the user touches the portion where the temperature-sensitive ink layer 3 is formed, for example, the clothes of Santa and the nose of the reindeer, the color reversibly changes from black to red. Also the letter Mer
ry X'mas can be reversibly changed from green to yellow, for example. The color change in this case can be achieved by a temperature-sensitive ink that changes from blue mixed with yellow pigment to colorless. The color change as described above returns to the original color shown in FIG. 3A after a while. The color change in the print image described above is caused by the color change of the temperature-sensitive ink layer 3 alone. However, by providing the structure as shown in FIG. The sketch may be covered with the ink layer 3 so that the color of the print image ink layer 2 and the color of the temperature-sensitive ink layer 3 are mixed. In other words, different colors may be superimposed so that they look different. In this manner, the plurality of temperature-sensitive ink layers 3 are partially used selectively, and the color mixture of the color of the print image ink layer 2 and the color of the temperature-sensitive ink layer 3 creates partial color changes of various print images. Can be served.

The color of the temperature-sensitive ink used in the temperature-sensitive print 10 according to the present invention is red, blue, green, brown, or the like.
It can be freely selected and used from among black series. Broadly classified from color change, there are those that change reversibly between colored and colorless, and those that change reversibly between colored A and colored B. The temperature change can be caused at any temperature in the range of -30 ° to + 60 °, but the temperature-sensitive ink used for the temperature-sensitive printed matter according to the present invention is at room temperature (normal room temperature) and body temperature. Alternatively, one that reversibly changes color between the temperatures of the breath to be blown is used. As described above, the color change is a dark color or black having a hiding power at room temperature, becomes almost colorless and transparent at the body temperature level, reversible when returned to the original color when left, and at room temperature. A color that reversibly changes to a B color at a body temperature level is used. When using temperature-sensitive ink, the temperature-sensitive temperature
It is necessary to control in consideration of the season and the place of use. For example, in Japan, the temperature at which the above-described color change occurs is slightly higher in the summertime, 30 to 31 ° C., and the appearance of the hidden sketch or the color change of the printed image is manually increased by the higher room temperature. Prevents it from becoming easy to happen without touching it. Conversely, in spring, autumn, and winter, the temperature is 27-28.
It is necessary to lower to ° C. This is because it is preferable that the speed of change of the temperature-sensitive ink is slightly higher for the purpose of the present invention.

A person generally wants to touch a protruding portion, but if the color of the portion changes instantaneously, the touching person can be surprised and the impact on a printed image can be increased. . The applicable range of the temperature-sensitive printed matter 10 according to the present invention is a printed matter such as a magazine, a picture book, a commercial printed matter such as a calendar, a poster, a catalog, a brochure, a flyer, a greeting card, a trading card, a paper container, a plastic molded article, Packaged in metal cans, etc., as well as stationery, toys, miscellaneous goods, etc.
In terms of the material, it includes all of a sheet-like base material that can be printed and processed for unevenness. Since the color change of the thermosensitive printed matter according to the present invention occurs instantaneously, for example,
When adopted in a picture book for infants and the like and read and listened to the picture book, it is possible to instantaneously change the face color and the like of the characters according to the progress of the story, thereby giving a sense of realism. In such a case, the place where the hand is touched may be from the back side of the temperature-sensitive printed material 10 according to the present invention, and the place where the hand is touched is extremely easy to understand because of the unevenness. In addition to the appearance and color change of a printed image, the answer to a specific question may be hidden in place of a sketch, and the correct answer may appear instantly when touched. It can be used for planning fortune-telling, lottery, etc. Further, when the present invention is applied to a package, by appropriately controlling the discoloration temperature, it is possible to serve also as an indicator for determining whether or not the storage temperature of the contents is appropriate, the temperature at the time of drinking, and the like.

[0012]

According to the present invention, the rough sketch appears instantaneously or the discoloration of the original print image occurs only by touching the part of the three-dimensional expression which has been embossed in synchronization with the rough sketch. Because it wakes up, not only the visual
It can give surprise and enjoyment with the touch sense,
A stronger impact can be given as compared with conventional flat printed matter.
