Are connected, paintings, photographs, etc. are completed. In this embodiment, as shown in FIG. 2 (a), the design is a cartoon, but any design such as landscape photographs and constellations may be used.

As shown in FIG. 3, a printing layer on which a part of a design such as a painting, a photograph or the like is printed on the surface of a part of the pieces 2 among the pieces 2, 2 ... In the present embodiment. 21 and a color changing layer 22 made of a reversible thermochromic dye.
The print layer 21 is a normal print and is given an appropriate color. The color-changing layer 22 is composed of a reversible temperature-sensitive color-changing dye and hides the printing layer 21.

The color-changing layer 22 is for realizing a thermochromism phenomenon in which the color changes with temperature, and is designed to develop color when the temperature is lower than the set temperature and to erase it when the temperature is higher than the set temperature. That is, the color changing layer 22 of this embodiment
The color-forming dye encapsulated in the microcapsules is reversibly bound to a coexisting solvent to form a color with a change in temperature, or is cut and erased.

Therefore, the temperature around the jigsaw puzzle 1 is
When the temperature is lower than the set temperature, a mixed color of the color of the print layer 21 for representing a design such as a painting or a photograph and the color developed by the color changing layer 22 appears. Further, when the ambient temperature is higher than the set temperature, the color of the discoloration layer 22 is erased, so that the color of the print layer 21 for representing a design such as a painting or a photograph appears.

The set temperature can be appropriately determined according to the type of reversible thermochromic dye, and in this embodiment, it is -4 ° C.
The temperature can be freely set within the range of 60 ° C to 60 ° C.

In this embodiment, each piece 2, 2 shown in FIG.
The color change layer 22 is formed in a specific building portion 23 among the cartoon patterns at the time of completion of the connection of ... And the color change layer 22 is not present in other portions, and the print layer 21 is exposed. Therefore, when the surrounding temperature of the jigsaw puzzle 1 is lower than the set temperature, as shown in FIG. 2 (b), the discoloration layer 22 formed in the specific building portion 23 of the cartoon pattern is colored. The mixed color of the color of the building portion formed on the printed layer 21 and the color of the color changing layer 22 becomes the color of the building portion 23.

Since the color development and the color erasing are used, it is possible to switch between the mixed color of the print layer 21 and the color change layer 22 and the color of the print layer 21. However, there is a delay time in the change of the color change layer 22, The mixed color may change under the assumption of the change. Therefore, in the present specification, "two types of patterns are displayed" means
This means that finally two types of patterns are displayed, and when the color change layer 22 changes, the patterns change continuously.

As described above, in this embodiment, the color is changed by the two layers of the printing layer 21 and the color changing layer 22, but if thermochromism can be realized by utilizing a reversible thermochromic dye. Any means can be adopted. Further, as the reversible thermochromic dye, any material can be used as long as it is a material that changes with temperature, and for example, a temperature-sensitive pigment or the like can be used.

Next, a modified example of the present invention will be described with reference to FIGS. FIG. 4 is a view showing the postcard 3, on which a picture of an airplane is formed. Postcard 3
Corresponds to a sheet member, and a pattern such as an airplane is formed by the printing layer 21 as in the above-described embodiment.

Is exposed. Therefore, when the temperature around the postcard 3 is lower than the set temperature, the discoloration layer 22 formed on the part 31 of the airplane develops color and is formed on the printing layer 21 as shown in FIG. 4B. Plane color and discoloration layer 2
The mixed color of the two colored colors becomes the color of the part 31 of the airplane.

Further, when the temperature around the postcard 3 becomes higher than the set temperature, as shown in FIG. 4A, the discoloration layer 22 formed on the part 31 of the airplane disappears and the printing layer 21
The color of the airplane formed on the part is the same as part 3 of the airplane.
The color is 1.

As a result, the color of the part 31 of the airplane formed on the postcard 3 changes at the boundary of the set temperature, and it is possible to display two types of patterns having different colors.

The present modification is not limited to the design of an airplane, and any design can be adopted, and the color of any part or the whole can be changed.

As described above, this modified example is a jigsaw puzzle 1
The color changing technique of is applied to the postcard 3, and the other description is the same as the description of the embodiment of the jigsaw puzzle 1 described above, and therefore the description is omitted.

If it is a sheet member, the postcard 3
Not limited to, it can be applied to posters and the like.

Further, although the sheet member is generally made of paper, it may be made of a polymer material such as synthetic resin or a cloth member.
