層をイｉするカラー箔を立体画像部分に転写する方法等
が採られている。[Prior art 1] Conventionally, a desired image is formed on the surface of a thermally expandable sheet 1 with a highly light-absorbing image forming material, and then the surface is irradiated with light. A method is known in which a three-dimensional image is formed by selectively heating and elevating only a portion (Japanese Patent Publication No. 59-35359, etc.). Screen printing is suitable for the initial formation of images in this method because it is inexpensive and can form images in large quantities. Since the printing ink used here must have high light absorption, it is usually black or brown. That is, even if an image was formed using red, blue, green, yellow, etc. printing inks and illuminated (1), a three-dimensional image could not be obtained because these printing inks had low light absorption. Therefore, when it is desired to colorize a three-dimensional image, a method is adopted in which, after forming the three-dimensional image, a color foil that matches the metal vapor deposited layer of the desired color is transferred to the three-dimensional image area.
なお、画像を形成しその画像に予め金属蒸着層を有する
カラー箔を転写した後光照射しても、金属蒸着層により
光が全反射するため画像部分を隆起させることはできな
い。Note that even if an image is formed and a color foil having a metal vapor-deposited layer is transferred to the image in advance and then irradiated with light, the image portion cannot be raised because the light is totally reflected by the metal vapor-deposit layer.
［Ｒ明が解決しようとする課題］
ところが、立体画像のカラー化を上記の方法により行う

テップが長くなり繁雑である。また、黒色等の画像部分

都合も生じる。[Problems to be Solved by R-Ming] However, when colorizing a stereoscopic image using the above method, a transfer operation is required after the stereoscopic image is formed, resulting in long and complicated work steps. Furthermore, if a color foil is transferred without completely covering an image area of black or the like, the underlying color is exposed and the appearance is poor.
本発明は上記実情に鑑み案出されたものであり、その技
術的課題は、光照射を受けて発熱することにより熱膨張
性シートの立体化を可能とする印刷用インクを提供する
ことにある。The present invention has been devised in view of the above-mentioned circumstances, and its technical object is to provide a printing ink that can make a thermally expandable sheet three-dimensional by generating heat when irradiated with light. .

ミニウム微粉末とを有するしのて・ある。[Means for Solving the Problems] The printing ink of the present invention is attached as an image on a thermally expandable sheet, and when irradiated with light, absorbs light energy and generates heat. This is a printing ink that selectively heats and raises only the portion corresponding to the image, and includes a binder and fine metal aluminum powder blended into the binder.
ここで、粘着剤とは、金属アルミニューム微粉末を除く
他のインク成分をいう。Here, the adhesive refers to ink components other than the metal aluminum fine powder.

に加熱して隆起させる。[Function] Since the printing ink of the present invention is made of fine metal aluminum powder, it absorbs light energy and generates heat when exposed to light. As a result, when the printing ink of the present invention is adhered as an image to the thermally expandable sheet and irradiated with light, only the portion of the thermally expandable sheet 1- corresponding to the image is selectively heated and raised.

インクが発熱するものと考えられる。なお、金属アルミ
ニウム微粉末の光を吸収する能力は大きくない。The reason why the printing ink of the present invention generates heat is thought to be because the light is repeatedly reflected diffusely between the countless number of metal aluminum fine powders 1, thereby improving the path length of the light within the printing ink. In other words, the light is reflected and repeatedly passes through a binder such as a resin with low heat absorption ability, so the light is absorbed little by little, and most of the light is absorbed by the ink before it leaves the ink.
It is thought that the ink generates heat. Note that the ability of the metal aluminum fine powder to absorb light is not large.

A desired image was printed on a thermally expandable sheet (Ne1%J "Stereocopy Vapor" manufactured by Minolta Business Machine Sales Co., Ltd.). Note that the thickness of the printing ink adhered by printing was 20 μm. After the printing ink was dried, it was irradiated with light using a light irradiation device (manufactured by Minolta Business Machine Sales Co., Ltd.) having a halogen lamp (900 W). As a result, the printing ink is irradiated with light and generates heat, which causes the thermally expandable microspheres to expand, and only the portion of the thermally expandable sheet that corresponds to the image rises, forming a blue three-dimensional image.

, it was reduced to 2 mm. This raised height is small because
This is thought to be because when the size of the metal aluminum fine V) powder exceeds 7 μm, which is approximately ]/3 with respect to the thickness of the printing ink of 20 μm, the diffused reflection effect of light decreases and the amount of heat generated decreases.

写作業等を必要としない。L Effect of the Invention 1 The printing ink of the present invention contains fine metal aluminum powder, so when it is irradiated with light, it absorbs light energy and generates heat. Therefore, it can be used as a printing ink when a three-dimensional image is formed by selectively heating and elevating the thermally expandable seal. Therefore, since a three-dimensional image is directly created by forming images in various colors and irradiating them with light, there is no need for a transfer operation for coloring after forming a three-dimensional image, as in the conventional case.
