関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a sheet for stereoscopic images, which is provided with a thermally expandable coating layer on the sheet surface and is capable of forming images with a three-dimensional effect.

トナーで画像を形成する。In order to form a three-dimensional image using the thermally expandable sheet described above, a desired image is formed on the sheet using a material with good light absorption. For example, an image is formed using black toner using an ordinary electrophotographic copying machine.

）。FIG. 1(b) shows a state in which an image 4 of black toner is formed on the coating layer 2 of the thermally expandable sheet P. Next, the surface of this sheet P is irradiated with light, and due to the difference in light absorption characteristics, only the image area 4 formed by the black toner is selectively heated to expand the thermally expandable microspheres 3, and the sheet surface A three-dimensional image is formed by raising it from above (see FIG. 1(c)).

合は単色で十分であった。一方。Conventionally, three-dimensional images made of thermally expandable sheets have been mainly used as Braille sheets for visually impaired people, and in this case, a single color was sufficient. on the other hand.

、立体感のある画像を形成することが困難であった。Three-dimensional images formed on sheets are expected to be used in a wide range of applications such as advertising media, picture books, etc., but in this case, colorization of the three-dimensional images is essential. However, since color toners have lower light absorption efficiency than black toners, they do not generate enough heat to sufficiently expand the thermally expandable microspheres on the sheet, making it difficult to form images with a three-dimensional effect.

着色材層が付着してシート面を汚すという問題があった
。To solve this problem, we formed an image using black toner, irradiated it with light to raise the image area, and then heated and pressed a film with a coloring material layer called hot stamp foil onto the sheet, and then applied heat to the raised toner image. A method of transferring a coloring material layer has been proposed, but in this method, the surface of the raised toner image becomes a rough surface, and the coloring material layer cannot be transferred uniformly. However, there was a problem in that the coloring material layer adhered and stained the sheet surface.
この発明は上記課題を解決するため、熱膨張性シートの

で被覆したことを特徴とするものである。In order to solve the above problems, this invention further covers the thermally expandable coating layer of a thermally expandable sheet with a casein film, and a low boiling point volatile substance is coated with a thermoplastic resin on the base sheet. The thermally expandable microspheres obtained by microencapsulation are dispersed in a binder made of a thermoplastic resin, and this is applied to the surface of the base sheet to form a thermally expandable coating layer. It is characterized in that it is further covered with a casein film.
また、前記熱膨張性被覆層の上を更に被覆するカゼイン
には柔軟剤を添加したものであってもよい。Furthermore, a softener may be added to the casein that further coats the thermally expandable coating layer.

が入ることを防ぐことができる。The thermally expandable coating layer is further coated with casein, which has good adhesion to the molten toner, or with a casein film containing a softener, so even if the toner image area is raised by light irradiation, the toner image surface will remain intact. The coloring material layer of the hot stamp foil can be uniformly transferred, and the coloring material layer does not adhere to areas other than the toner image area. By adding a softener, it is possible to prevent hair cracks from occurring when the image area is raised.
更に、フィルムの材料としてカゼインを選択することで
、１回の塗布工程で必要な厚みのフィルム層を形成する
ことができる。Furthermore, by selecting casein as the material for the film, a film layer of the required thickness can be formed in one coating process.
以下、この発明の実施例について説明する。 Examples of the present invention will be described below.

Reference numeral 11 denotes a base sheet, which has sufficient rigidity and heat insulation to prevent the back side of the base sheet from expanding when thermally expandable microspheres, which will be described later, expand due to heating, and a temperature at which the microspheres expand. It is made of a material that does not soften, such as paper, synthetic paper, synthetic resin sheet, plywood, metal foil, etc.

Particle size 10-30μ microencapsulated with thermoplastic resin such as vinylidene chloride-acrylic acid ester copolymer
Thermally expandable microspheres 13 are formed by coating and drying on the base sheet 11 together with a binder made of a thermoplastic resin such as a vinyl acetate polymer, an acrylic polymer, a methacrylic acid polymer, or a styrene-butadiene polymer. Note that it is also possible to use a granular heat-sensitive organic foaming agent such as azobisisobutyronitrile as the heat-expandable microspheres.

の結果間らかになった。14 is a film layer that prevents heat generation in the image area due to light irradiation,
It is heat resistant enough to withstand the heat during hot stamp foil processing and can fix toner images well, and is made of materials that do not easily adhere to hot stamp foil adhesives, such as polyester film and specially processed paper. You can, but
Experiments have shown that a film layer made of casein or a material to which a casein softener has been added provides particularly good results.

。In order to form the casein film layer 14 on the thermally expandable coating layer 12, an aqueous solution consisting of casein and a casein softener is coated on the thermally expandable coating layer 12 and dried.
．． A film layer with a thickness of 5 μm to 5 μm can be formed. The preferred thickness is 1.0 to 3.0 μm.
フィルム層をカゼインのみで形成することはもちろん可

善のためにカゼイン柔軟剤をカゼインに添加するとよい
。It is of course possible to form the film layer only from casein, but since casein becomes a hard coating when dried, when used in a 3D image sheet, when the thermally expandable coating layer thermally expands, it can cause elongated layers called hair cracks. Since cracks occur and the sheet surface loses its appearance, a casein softener may be added to the casein to improve this.

0 polyethylene glycol (Nirasan Polyethylene Glycol #200-2000 manufactured by NOF Corporation) is suitable, and other glycerin and tributyl phosphate also exhibit similar effects. In this case, rough casein (produced in New Zealand) was used as the casein.
カゼインと柔軟剤であるポリエチレングリコールの混合
比率は、カゼイン１００重量部に対してポリエチレング
リコール１〜４０重量部であり、好ましくは１０〜３０
重量部が適切な混合比率である。The mixing ratio of casein and polyethylene glycol as a softening agent is 1 to 40 parts by weight, preferably 10 to 30 parts by weight of polyethylene glycol to 100 parts by weight of casein.
Parts by weight is an appropriate mixing ratio.

）。The coating treatment with the hot stamp foil S is performed as follows. First, the adhesive layer 350 side of the hot stamp foil S of a desired color is superimposed on the side of the sheet Q on which the toner image 15 is provided, and the foil is heated and pressed between known heat rollers. As a result, the adhesive layer 35 of the hot stamp foil S firmly adheres to the molten toner forming the toner image 15 (see FIG. 2(d)). At this time, the adhesive layer 35 does not adhere to the casein film 14 on the sheet 11. When the base film 31 of the hot stamp foil S is peeled off from the sheet Q, the coloring material layers 33 and 34 of the hot stamp foil S remain adhered only on the toner image 15 (see FIG. 2(e)).

付着しないのでシート表面を汚すことがない。As explained above, in the 5K sheet for stereoscopic images of the present invention, the thermally expandable coating layer is further coated with a casein film that has good adhesion to molten toner, so it is subjected to light irradiation treatment to heat the toner image area. Even if the expanded coating layer rises, the toner image surface remains smooth and the colorant layer of the hot stamp foil can be uniformly transferred. Furthermore, since the coloring material of the hot stamp foil does not adhere to the film surface on which the toner image is not formed, the sheet surface is not stained.
