Or, a decorative paper coated with a protective resin layer or a polyvinyl chloride resin film as a base material is printed with wood grain on the surface, and then a transparent polyvinyl chloride resin film is laminated or the protective resin layer is coated.

Moreover, since it does not have thermoformability, it cannot be applied to a three-dimensional curved surface by a hot press lamination method, a vacuum lamination method, an injection molding simultaneous lamination method, or the like. On the other hand, those based on polyvinyl chloride resin film,
Although the above points are excellent, harmful substances such as hydrogen chloride are generated at the time of incineration, which has been regarded as a social problem from the viewpoint of environmental protection.

Specifically, a decorative sheet or the like based on a polyolefin-based resin, a polyester-based resin, an acrylic-based resin, or the like can be given.

It has many problems such as bending workability such as processing and lapping, and three-dimensional thermoformability such as vacuum forming, etc., and it is more expensive than polyvinyl chloride resin in terms of cost.

シートが専ら使用されて来た。As for the transfer sheet, a transfer sheet using, for example, a polyolefin resin laminated paper or a polyester film as a base sheet has been used, but these transfer sheets are also inferior in bending workability and three-dimensional thermoformability. Therefore, for example, a polyvinyl chloride resin film is used for a V-cut transfer (use a base sheet instead of a surface protection film and peels off after V-cut processing / bending adhesion), wrapping transfer, vacuum forming transfer, etc. Transfer sheets have been exclusively used.

Therefore, from the viewpoint of environmental protection, the base sheet is not used as the above-described decorative sheet. As in the case above, substitution with a material other than polyvinyl chloride resin is required, but no material comparable to polyvinyl chloride resin has been found in terms of performance and price, which has been a problem. .

It is determined. Generally, the total thickness of the decorative sheet is 20 to 5
When the thickness of the foamed thermoplastic resin layer 1 is too small, the effect of the present invention cannot be sufficiently obtained. When the thickness is too large, the tensile strength and the interlayer strength are reduced.
It is preferable to set the range to about 150 μm. On the other hand, the thickness of the non-foamed thermoplastic resin layer 2 is preferably in the range of about 5 to 50 μm from the viewpoint of flexibility and thermoformability.

As shown, the foamed thermoplastic resin layer 1 may be on the front side. Generally, it is preferable that the non-foamed thermoplastic resin layer 2 be on the surface side in terms of surface physical properties such as abrasion resistance, scratch resistance, and solvent resistance. However, in some applications, the foamed thermoplastic resin layer 1 may be used as the front side for the purpose of giving a soft touch to the surface.

A surface protective layer 4 can be provided on the picture layer 3 for the purpose of protecting and improving the abrasion resistance, scratch resistance, solvent resistance and the like of the picture. The surface protection layer 4 is made of, for example, a polyurethane resin,

It can also be composed of layers or more. 5 and 6 show the non-foamed thermoplastic resin layer 2 on both front and back sides of the foamed thermoplastic resin layer 1.
1 shows an example of a three-layer configuration in which the layers 1 and 22 are stacked. With this configuration, compared to the two-layer configuration, the front and back surfaces are constituted by the non-foamed thermoplastic resin layers 21 and 22, so that both surfaces have high surface strength, and scratches and breakage are less likely to occur. The difference in the expansion and contraction behavior of the front and back surfaces due to temperature change and pressure change is eliminated, and curling can be prevented.

Is dispersed in two layers, so that the flexibility and heat deformability can be improved while maintaining the same mechanical strength such as tensile strength as when only one non-foamed thermoplastic resin layer 2 is used. There are advantages. Conversely, it is also possible to increase the total thickness of the non-foamed thermoplastic resin layers 21 and 22 and to improve mechanical strength such as tensile strength while maintaining flexibility and thermal deformability.

である。Further, as shown in FIG. 7, for example, the foamed thermoplastic resin layer 1 may be divided into a plurality of layers 11 and 12, and a non-foamed thermoplastic resin layer 22 may be disposed between those layers. Such multilayering makes it easier to achieve both mechanical strength, such as tensile strength and interlayer strength, and workability, such as flexibility and thermal deformability, without contradiction. Because the total thickness can be increased while reducing the thickness per layer of the foamed thermoplastic resin layers 11 and 12, it is possible to improve the flexibility and the heat deformability without lowering the interlayer strength. It is also advantageous in terms of price. On the other hand, since the total thickness can be increased while reducing the thickness of each of the non-foamed thermoplastic resin layers 21, 22, and 23, the tensile strength can be improved without lowering the flexibility and thermal deformability. Because it is possible.

Above all, if there is a significant difference between the thickness of the non-foamed thermoplastic resin layer on the outermost surface and the thickness of the non-foamed thermoplastic resin layer on the outermost surface, curling is likely to occur, so that both have approximately the same thickness. Is preferred, even if they differ for some other purpose,
It is preferable that the ratio between the two be in the range of 2: 3 to 3: 2. Further, from the viewpoints of flexibility, heat deformability and interlayer strength, it is preferable that each of the thicknesses of the foamed thermoplastic resin layers 11 and 12 be within a range of 15 to 150 μm.

点を有するものである。Since the decorative sheet of the present invention is formed by laminating at least a foamed thermoplastic resin layer and a non-foamed thermoplastic resin layer, it can be compared with a conventional decorative sheet comprising only a non-foamed thermoplastic resin layer. Therefore, the foamed thermoplastic resin layer has a function of buffering the deformation of the sheet, and the thickness of the non-buffered non-foamed thermoplastic resin layer can be reduced, thereby causing problems such as environmental pollution other than polyvinyl chloride resin. Even if no resin is used, a sheet with sufficient flexibility can be obtained as a whole sheet. For example, with respect to the suitability for bending such as lapping and V-cut, and the suitability for thermoforming such as vacuum forming, conventional polychlorinated A sheet having performance comparable to a vinyl resin-based decorative sheet can be easily obtained. Moreover,
By providing the foamed thermoplastic resin layer, it is possible to reduce the amount of resin used even for sheets of the same thickness, so that it has various excellent advantages such as being able to be manufactured at low cost. is there.
