Description of the Related Art Conventionally, as a nubuck leather-like sheet, napped fibers of ultrafine fibers are formed on the surface of the epidermis and sanded (buffing) to make short hairs, or polyurethane resin is used. It has been put into practical use that it is applied to a substrate by impregnation or coating, and the skin layer on the surface on which the microporous film is formed is ground and removed by a wet method. In general, the nubuck tone often refers to the latter process. However, this method requires a long time for the manufacturing process, the manufacturing equipment to be used is limited, and therefore the price of the product is high. is there.
On the other hand, a so-called dry method (which does not form a microporous film), which is produced by applying a skin layer and an adhesive layer to release paper and bonding the same to a base material, does not use a wet method. Although the manufacturing equipment of the method is not required and the cost is advantageous, the final product does not have the same appearance and the touch of the surface, and there is a problem in quality.

の配合剤を添加することができる。The skin layer is formed without forming a microporous film, and from the viewpoint of the formability of a matte uneven pattern on the surface and the quality of the product such as elasticity, wet feeling and slimy feeling. A coating of polyether polyurethane resin is particularly suitable. In order to impart such quality, polyurethane resin has 100% modulus of 150 kg / cm.
2 or less is desirable. The polyether-based polyurethane resin is preferably a polyether / ester-based or polyether / carbonate-based polyurethane resin, more preferably at least 50% by weight of polyether in the polyurethane. The thickness of the epidermis layer is usually 20 to 40 μm. Various pigments for coloring and other compounding agents can be added to the polyether polyurethane resin.

い。The method of forming a matte uneven pattern on the surface of the skin layer is not particularly limited. A preferred method is to use a release paper having a mat-like uneven pattern, and to apply a polyether-based polyurethane resin solution to the release paper by coating or the like, or to generate the polyurethane resin on the release paper. This is a method in which a matte pattern is transferred to the surface of the coating by peeling the release paper after forming the resin coating. In the leather-like sheet of the present invention, only the convex portion of the matte uneven pattern on the surface of the skin layer is ground, and the height difference of the unevenness (the depth of the grain) is required to grind only the convex portion. Is preferably at least 5 μm.

The adhesive used is not particularly limited as long as it can firmly bond the both and does not impair the quality of the product, but it is a preferred polyurethane adhesive. The total thickness of the skin layer and the adhesive layer is required to be at least 40 μm from the viewpoint of the texture and strength of the leather-like sheet, but if it exceeds 80 μm, the texture becomes worse, which is not preferable.

Grinding is usually performed with sandpaper or the like, but other methods may be used. By grinding only the surface of the convex part, the gloss of the concave part and the convex part becomes closer,
The entire surface of the skin layer is matte finished. A schematic view of the leather-like sheet of the present invention is shown in FIG.
