[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to the drawings. FIG. 1 shows an example of the cosmetic sheet of the present invention. The decorative sheet 1 has an intermediate layer 3 made of a liquid-impervious plastic layer or the like, and is obtained by laminating a first layer 2 having an oil absorbing function and a second layer having excellent water absorbing property, In this embodiment, a three-layer structure is employed.

As the liquid-impermeable intermediate layer, a synthetic resin film such as a polyester film, a polystyrene film, a polypropylene film, a polyethylene film and a biodegradable film can be used. As the biodegradable film, Palgreen LC (manufactured by TOCELLO)
And the like. The intermediate layer is not limited to a liquid-impermeable plastic film, and may be a layer provided with a liquid-impermeable resin or a biodegradable emulsion by coating or printing. In particular, the biodegradable film is preferable because it has a small influence on the environment because the biodegradable film is naturally decomposed even if the cosmetic sheet 1 is inadvertently discarded after use. The thickness of the intermediate layer is in the range of 3 to 15 μm. Preferably, 5-1
0 μm. If the thickness is less than 3 μm, the strength is weak and the material is easily broken during use, and it is difficult to join the front and back layers. On the other hand, if the thickness exceeds 15 μm, the sheet becomes thicker and harder as a whole, and the usability deteriorates. The intermediate layer may be composed of a plurality of layers.

The fibers used as raw materials for the first and second layers include wood pulp fibers, bast fibers such as manila hemp, flax, hemp, jute, mulberry, mitsumata, and goose, cotton, straw, bamboo, and the like.
Mainly pulp such as non-wood pulp fiber such as kenaf,
Chemical fibers such as acrylic and rayon, and animal fibers such as silk can also be mixed. These fibers may be used alone or in combination of two or more. The basis weight of each of the first and second layers is in the range of 5 to ²⁰ g / m ² . By setting the grammage within the above range, the entire cosmetic sheet becomes thinner and becomes a supple and soft-feeling cosmetic sheet.
If the basis weight of each of the first and second layers is less than 5 g / m ² , the feeling of touch is impaired, and if the basis weight exceeds 20 g / m ² , the cost increases, and the decorative sheet becomes thick and hard to use. Feeling worse.

It is preferable that the oil-absorbing layer contains an inorganic filler in an amount of 20% by mass or less. If the content exceeds 20% by mass, the paper quality strength is reduced. When an inorganic filler is contained, the transparency of the oil-absorbing layer is low before the oil-absorbing, and the transparency is improved when the oil-absorbing layer is absorbed. This inorganic filler includes clay, talc,
Examples thereof include calcium carbonate, white carbon, titanium oxide, and hydroxyapatite. Titanium oxide or hydroxyapatite is particularly suitable because it has an antibacterial effect and an effect of selectively removing oxidized sebum.
In addition, it is preferable to include an inorganic filler in the oil-absorbing layer because the density becomes higher and the smoothness, flexibility, oil-absorbing property and sweat-absorbing property are also improved.

When the first layer and the second layer are colored in different colors with a coloring agent, the contrast between the grease-absorbed portion and the non-grease-absorbed portion becomes clear, so that the grease-absorbing effect can be more easily visually confirmed. Become. In this case, if the intermediate layer is transparent, the other layer can be visually recognized through the intermediate layer, and the contrast can be further clarified. Even if the intermediate layer is colored in a different color tone from the first layer and the second layer, the oil absorbing effect can be visually confirmed.
Known dyes and pigments such as basic dyes, acid dyes, and direct dyes can be used as the colorant. At this time, further effects can be obtained if the fat-filled paper contains an inorganic filler.

As a method of laminating the liquid-impervious intermediate layer, the first layer and the second layer, it is possible to use an adhesive or the like, but it is desirable to form the intermediate layer with a resin. It is preferable that the layers are laminated by the adhesiveness of the resin itself. Specifically, a lamination mode such as laminating the first layer or the second layer by an appropriate coating method or utilizing fusion of a resin can be adopted.

The water-absorbing layer may contain a humectant, such as jojoba oil, glycerol, 1,3-butylene glycol, hyaluronic acid, or a substance having a moisturizing function. Is mentioned. After obtaining the laminate, the humectant can also impregnate the water absorbing layer with a humectant by spraying or coating.

It should be noted that the first layer and the second layer may be the same oil absorbing or water absorbing functional layer, but it is preferable that the first layer and the second layer are separated into a first layer and a second layer, one surface of which is the oil absorbing functional layer, and the other surface. Is desired to be a water-absorbing functional layer.

Next, Examples and Comparative Examples of the present invention were prepared and tested for their softness, punch force, amount of oil absorption, water absorption, suitability for removing makeup, and suitability for wiping. Table 1 shows the results. In both Examples and Comparative Examples, decorative paper was superimposed on both surfaces of a polyethylene film, and the laminated state was heated and pressed by a pressure roller to obtain a three-layer laminated decorative sheet.
