とれた性質を満足するものはなかった。2. Description of the Related Art Conventionally, as a decorative sheet used for applications such as a decorative plate, a decorative sheet mainly composed of a vinyl chloride resin sheet has been most popular. However, vinyl chloride resin is said to cause hydrogen chloride gas during incineration, acid rain caused by this gas, or dioxins during incineration.In recent years, vinyl chloride resin sheets have been used from the viewpoint of environmental problems. The demand for non-decorative sheets is increasing. However, for resin sheets other than vinyl chloride resin, the appropriate flexibility of vinyl chloride resin sheet,
None of them satisfy the well-balanced properties such as abrasion resistance, chemical resistance, stain resistance, and weather resistance.

と消失してしまう欠点があった。Further, according to the manufacturing method, in the conventional vinyl chloride resin decorative sheet, since the uneven pattern is mechanically formed by the embossing plate to which heat and pressure is applied, the provided uneven pattern is 70% of the embossing plate. Only reproduced to a degree,
The uneven pattern also has a drawback that it disappears when left in an atmosphere of about 100 ° C. for a long time.

In addition, when printing on a polyolefin resin surface, surface treatment such as corona discharge treatment, or when using wood-based boards and the adhesives currently used for PVC sheets A resin backcoat was required.

FIG. 1 is a sectional view showing an example of a decorative sheet according to the present invention. FIG. 2 is a schematic view showing an example of a manufacturing process of the decorative sheet according to the present invention. Optional pattern layer (12)
Melting while blowing ozone gas (G) between a web-shaped paper base sheet (18) provided with an anchor coat layer (13) and a cooling roll (22) having an embossing plate (a) on the surface. The extruded polyolefin resin (14) is extruded by an extruder, and at the same time, an embossed sheet (19) formed by forming an uneven pattern (15) by embossing on the polyolefin resin layer (14) is pressed by a pressure roll (2).
By laminating according to 1), a decorative sheet having an uneven pattern (15) on the surface can be obtained. In addition, after the surface of the obtained embossed decorative sheet (10) is subjected to corona discharge treatment, an ink layer (16) by wiping is embedded in the concave portions of the concavo-convex pattern (15), and then the surface protective layer (17) is formed on the outermost surface. By providing it, it becomes possible to improve the design.

なるものが使用できる。Examples of the polyolefin resin (14) used in the present invention include polypropylene homopolymer, random polymer and block polymer,
As the soft component, any one of low density polyethylene, α-olefin, ethylene-propylene copolymer rubber, or a resin formed by simply mixing and adding 5 to 30% by weight of a mixture can be used.

ンが最適と言える。The type of polypropylene polymer is
When the obtained sheet is required to have heat resistance, hardness, etc., it is a homopolymer, when it is required to have impact resistance, it is a block polymer, and when it is required to have impact resistance, low temperature processability and transparency. A random polymer may be appropriately selected.
However, since the low temperature processability which is a characteristic of the vinyl chloride resin sheet is emphasized, it can be said that the random polymerization type polypropylene is the most suitable.
【００１２】前記添加される軟質成分の量は、５重量％

などの不都合があるからである。The amount of the soft component added is 5% by weight.
Below, there is no effect on the low temperature processability, and above 30% by weight, the elasticity of the obtained sheet is too large. The soft component to be added is simply mixed, but not only the process is simple, but when both are crosslinked, the transparency is impaired, or the interface of the soft component which crosslinks in polypropylene and takes a domain structure is received. This is because there is an inconvenience such as a whitening phenomenon caused by the impact.

た樹脂含浸紙が特に最適である。Further, in order to obtain a concealing property when it is used as a decorative sheet, it is desirable that the paper base material (11) be arbitrarily colored such as titanium paper. Furthermore, resin-impregnated paper impregnated with an acrylic or latex resin is particularly optimal so as to withstand bending.

系のインキも使用可能であるが塩素を嫌うという点から
は本発明の主旨からは外れる。The ink used for the pattern layer (12) is not particularly limited as long as it adheres well to the paper substrate (11), but it is a urethane type ink because of the cohesive force of the ink itself and versatility. Ink is the best. Further, chlorinated olefin-based inks can be used because of their close contact with olefin-based sheets, but this is outside the scope of the present invention in that chlorine is disliked.

In the case of 0 mm), the molten polyolefin resin on the side in contact with the surface of the anchor coat layer (13) is sprayed to oxidize the surface.

ン酸などの公知の物を使う。For the resin layer forming the concavo-convex pattern (15) by the embossing plate, a polyolefin resin may be selected for the same reason as the paper base material. In particular, since it is a sheet to be embossed, it is required to have transparency. Therefore, in some cases, it is possible to add a nucleating agent to polypropylene to improve transparency. As the nucleating agent, known substances such as silica and stearic acid are used.

い。Since the embossed sheet (19) attached to the paper base material sheet (18) is transparent, it is a molten polyolefin in order to prevent ultraviolet rays against the paper base material, the anchor agent and the ink of the picture layer. In addition to antioxidants and light stabilizers, ultraviolet absorbers represented by benzotriazoles are added to the resin. Further, since it is a transparent resin layer, unlike a paper substrate, no coloring pigment is added.

る。The molten polyolefin resin (14) extruded here is cooled and solidified and embossed at the same time by a cooling roll (22) having an embossing plate. Conventionally, it is a vinyl chloride decorative sheet. It is not a mechanical embossing like the heating doubling embossing that is done, but a state in which the molten resin is put in the mold, so even a very fine embossing such as used for holograms It can be entered without any problem, and the embossed pattern can also be obtained with good heat resistance of the uneven pattern.

The present invention provides a decorative sheet using resin-impregnated paper or titanium paper as the paper base material and a method for producing the same.Because there is embossing when the sheets are bonded by dry lamination as in the conventional case, The problem that air remains on the bonded surface is eliminated. Also, even if the surface treatment such as corona discharge treatment is not performed before printing on the polyolefin resin, when using the adhesive currently used for PVC sheets with the paper base material, the urethane resin back coat I no longer need it.

れた効果を生ずる。As described above in detail, according to the method of the present invention, since vinyl chloride is not used at all, there is no fear of environmental problems, and the physical properties are the same as those of vinyl chloride but rather higher. A decorative sheet can be obtained, and in particular, since a molten resin is extruded and embossed, a decorative sheet having excellent reproducibility and heat resistance of the embossing plate can be obtained. In addition, a sheet was obtained in which air was not mixed during lamination. Furthermore, by using a paper base material, it is possible to adhere using the currently used PVC sheet adhesive as it is, as well as corona discharge treatment for printing and backcoat pretreatment, and backcoat for adhesion. It produces excellent effects such as eliminating unnecessary use.
