絵本に関する。TECHNICAL FIELD The present invention relates to a thermosensitive color-changing picture book. More specifically, a thermochromic pattern is overprinted on the non-color-changing image, and the two sides are made to alternately retain and visualize the thermochromic pattern and the non-color-changing image at room temperature by applying heat or cold heat. The present invention relates to a thermosensitive color change picture book having a property.

とする。Means for Solving Problems The thermosensitive color-changing picture book of the present invention comprises a non-color-changing image formed on the surface of a support, and a thermochromic pattern whose visual density when coloring is darker than that of the non-color-changing image is overprinted. A picture book having a two-sided property that allows the non-color-changing image and the thermo-color-changing pattern to be alternately retained and stored in the normal temperature range by application of heat or cold heat, and the thermo-color-changing pattern is temperature-color. Colored with a coloring material containing a quasi-reversible temperature-sensitive dye that exhibits a large hysteresis characteristic in terms of density and changes color, and the temperature of the quasi-reversible temperature-sensitive dye rises when the temperature-sensitive dye is in the first hue state. In the process, the second
Upon reaching the temperature t 3 the first color begins to discolor, become completely second color at a second higher temperature t 4 above temperature range than the temperature t 3, the temperature sensitive dye is in the second color state In the process of lowering the temperature, when the first temperature t 2 lower than the second temperature t 3 is reached, the second hue starts to change color, and in the temperature range lower than the temperature t 1 lower than the first temperature t 2. A temperature-sensing temperature that exhibits a hysteresis characteristic such that the hue becomes completely the first hue and both the first hue and the second hue can coexist within a temperature range between the first temperature t 2 and the second temperature t 3. A dye, wherein the temperature t 1 is a temperature between 0 ° C. and 15 ° C., and the temperature t 4
Is a temperature between 27 ° C. and 90 ° C., the first temperature t 2
The temperature range between the second temperature t 3 and the second temperature t 3 is within the range of 10 ° C. to 35 ° C., and a quasi-reversible temperature-sensitive dye whose visual density during coloring exceeds that of a non-color-change image is selected. It is a requirement.

About the picture of the doll whose cheeks are pale vermilion and whose eyelids are pale purple, blue ← → colorless due to temperature change (point A 10 ℃,
C point 32 ° C), purple ← → colorless (A point 10 ° C, C point 32)
℃) and pink ← → colorless (A point 10 ℃, C point 32)
Each of the inks containing a quasi-reversible temperature-sensitive dye that changes in temperature (.degree. C.) was overprinted on the lips, cheeks, and eyelids, respectively, and dried to obtain a picture of a doll with a two-faced face. (The support was the same as in Example 1 and was bound in the same manner.) After warming the face of the picture book by hand to make it look like a face with normal makeup, it was heated to about 25 ° C. at room temperature for about 10 minutes. When cooled with cold water at ℃, the lips changed to blue, the cheeks changed to purple, and the eyelids changed to pink, giving a psychedelic appearance.
It was kept stable in the temperature range of ℃ to 29 ℃.
