[0002]

2. Description of the Related Art Heretofore, some proposals have been disclosed regarding a thermochromic cloth composed of thermochromic fibers or a thermochromic cloth provided with a thermochromic layer on the surface of a cloth (for example, Japanese Patent Publication No.
-37746, etc.). The conventional thermochromic cloth described above,
It is applied to the field of doll costumes and toys, and even if you can enjoy various color changes due to temperature changes, the appearance of thermochromic cloth is a reversible change from colored (1) to colored (2). However, the color change and the appearance before and after the color change were monotonous, and the appearance of the object hidden behind the cloth could not be seen, and the taste and decorativeness were not satisfied.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional thermochromic cloth. That is,
Not only does the color tone of the fabric change, but the fabric also exhibits various aspects as the fabric discolors, and a new glitter effect is added to satisfy the unique aesthetic and decorative effects, making it suitable for doll costumes, toys, decoration fields, etc. It is to provide a suitable thermochromic glittering laminate.

[0004]

The present invention will be described with reference to the drawings (see FIGS. 1 to 3). The present invention requires a thermochromic translucent fabric 2 having a thermochromic layer formed on the surface of the fabric and having a visible light transmittance of 10 to 80%. Furthermore, the glittering processed body 3 is arranged in contact with or close to the lower layer of the thermochromic translucent fabric 2 and the thermochromic translucent fabric is penetrated so that the glitter effect is visible. The thermochromic glittering laminate 1 characterized by the above is required. Furthermore, the thermochromic glittering laminate 1 is required to be a doll costume made of a combination of a thermochromic transparent cloth 2 having a visible light transmittance of 10 to 80% and a glittering sheet material. And

The present inventor diligently studied in order to make the appearance, color tone and color change of the thermochromic cloth before and after discoloration more rich, and as a result, the thermochromic cloth has a visible light transmittance of 1 or less.
By using the thermochromic translucent cloth 2 in the range of 0 to 80%, the form of the object on the back can be visually seen through the cloth, and the appearance of the object is the color change of the cloth. It was found that various aspects were exhibited by. Further, by disposing the glittering processed body 3 in the lower layer of the thermochromic transparent cloth 2 having a visible light transmittance of 10 to 80%, the thermochromic effect of the cloth and the reflected light of the glittering processed body 3 The present invention has been completed by finding that a unique visual effect woven by the glitter effect can be expressed. That is, when the glittering processed body 3 is arranged in the lower layer of the thermochromic translucent fabric 2, the reflected light of the glittering processed body 3 in the lower layer is seen through the fabric, so that the color change and reflection of the fabric are reflected. By combining light, it is possible to effectively exhibit a variety of thermal discoloration aspects that combine the glitter effect. In the above description, when the visible light transmittance of the cloth is 10% or less, the glittering processed body 3
The degree of blocking the reflected light is large, and the appearance cannot exhibit glitter. On the other hand, when the visible light transmittance of the fabric is 80% or more, the amount of the thermochromic material adhered to the fabric is small, and the color density of the thermochromic layer provided on the fabric at the time of color development is not sufficient.

The glittering processed body 3, which is placed in contact with or close to the lower layer of the thermochromic light-transmitting cloth 2, is placed at a position where the glittering effect of reflected light can be seen through the light-transmitting cloth 2.
