た。2. Description of the Related Art As buildings and fittings are deluxe and diversified, demand for a metal-like appearance giving a high-quality and heavy impression, for example, a decorative metal sash having a stainless-like appearance is increasing. However, if the entire sash is made of stainless steel, it is expensive, and it is not preferable because it is heavy and the construction is not easy. Due to limitations in processing technology, it is not always possible to manufacture an aluminum sash having an arbitrary cross section. To solve the problem, a decorative sheet for exterior is attached to a conventional aluminum sash to give it a metallic luster. The decorative sheet used for this purpose is manufactured according to the process of laminating a polyvinyl chloride film on a metal film deposited on a polyester film and providing a squeezing emboss on the surface. When using this manufacturing method, when laminating with PVC,
When embossing or attaching to a substrate such as a sash,
There is a danger that the deposited metal layer will be whitened by the action of heat, tension, or residual solvent, and when it is tolerated, cracks may occur in the deposited metal film. Even though the metal deposition film was safe, the plastic film was sometimes whitened or wrinkled. Furthermore, mixing of air bubbles into the adhesive,
Failure during lamination, such as uneven coating and color turbidity of the adhesive, was seen from the surface, and the appearance of the decorative sheet was sometimes impaired.

りしてもよいことはいうまでもない。FIGS. 1 to 5 show a method for manufacturing a decorative sheet according to the present invention.
As shown in the figure in order, the diaphragm 12 facing the release surface 11
The synthetic resin having good weather resistance is cast on the process paper 1 (FIG. 1) on which the
After the metal 3 is deposited on the sheet 2 (see FIG.
Figure), heat-resistant film 5 is adhered to the deposition surface (Figure 4),
The process paper 1 is peeled off (FIG. 5). If you want to enhance the aesthetics or design of the decorative sheet,
Before performing metal deposition, it is preferable to print a picture on a sheet formed by casting. This decorative sheet is preferably backed with a backing sheet. The lamination of the backing sheet is preferably performed before the process paper is peeled off. As the process paper, use a heat-resistant and dimensionally stable material such as PET or paper as a base material. The release surface is preferably provided as a coating having a thickness of 10 to 30 μm by extrusion coating a base material with a resin that does not adhere to the resin to be cast, such as polymethylpentene, PP, PE, PVDF, or ETFE. The squeezing may be performed by using a cooling roll at the time of the extrusion coating as an embossing plate, or by performing an embossing process thereafter. The casting is performed using a roll coater, a knife coater, a comma coater, or the like, followed by hot air drying. From the viewpoint of the surface properties such as weather resistance and abrasion resistance that the product decorative sheet should have, the coating thickness should be 50 μm or more and about 100 μm. The resin used here is preferably a transparent polyvinyl chloride or acrylic resin, and the former is particularly typical. Polyvinyl chloride contains 10 to 30 phr of a plasticizer at a polymerization degree of about 800 to 1500, and has a viscosity of 1000 to 1000 to which a stabilizer, an ultraviolet absorber and a diluting solvent are added, from the viewpoints of film forming suitability, ease of printing, and price. 5000cps sol is easy to use. The metal layer is formed to a thickness of 100 to 500 mm by vacuum deposition or sputtering of Al, Cr, Au, Cu, Ni, Ti, or the like. If better weather resistance is desired, use Cr, Au, Ti. The heat-resistant film is preferably a film of PET, PC, TAC, polyimide or polyacrylate having a thickness of 12 to 38 μm. The backing sheet may be a conventional one. The typical one is
It is a PVC sheet having a thickness of 50 to 200 μm and a plasticizer of 10 to 30 phr. Needless to say, a pressure-sensitive adhesive may be applied to the decorative sheet produced by the method of the present invention and, if desired, a release paper may be applied, or a protective sheet may be provided.

る。The method for producing a decorative sheet according to the present invention uses process paper whose dimensions hardly change even when heated or a little tension is applied, and performs each of the sheet forming, vapor deposition and laminating steps thereon. Thereby, it is possible to obtain a decorative sheet product while preventing whitening, cracking or wrinkling of the plastic film and the metal layer due to heat and tension during processing. Casting the formation of the textured film also helps and assists in providing the condition that the residual stress in the formed sheet is substantially zero.

のおそれもなく施工できる。According to the production method of the present invention, as described above, a decorative sheet having a metallic luster can be obtained without causing whitening, wrinkling or cracking of the metal-deposited film or the synthetic resin sheet. In this decorative sheet, metal is directly vapor-deposited on the resin to be the surface, and it is not based on the adhesive. Therefore, defects such as air bubbles in the adhesive, coating unevenness, and color turbidity can be avoided in principle, and the appearance is improved. It will be excellent. Since the synthetic resin sheet on the surface is formed by casting, when this decorative sheet is applied to an aluminum sash or the like, it can follow the surface shape well and can be constructed without fear of whitening or the like.
