ることができる。The present invention relates to an improvement in a method for producing a decorative sheet made of coated paper, particularly raised coated paper. BACKGROUND OF THE INVENTION Conventionally, decorative sheets of various structures have been proposed, but each has its own drawbacks. for example,
Ordinary coated paper, which is made by printing a pattern on a base paper made of thin paper and then applying an overprint, cannot prevent moisture from penetrating through the surface, and it also has the disadvantage of being flammable. Although PVC sheets used as PVC sheets can prevent moisture from penetrating through the surface, they have drawbacks such as being expensive and requiring the use of expensive adhesives. There are also problems with physical properties such as solvent properties. Furthermore, laminated processed paper, which is made by laminating a plastic film on the surface of ordinary printing paper, is known as a laminated paper with vinyl chloride resin clear film, polyester film, polyethylene film, polypropylene film, etc. requires a film bonding process, which makes the process complicated and increases costs. Additionally, air tends to be sucked in during bonding, resulting in poor surface properties. KProblem to be solved by the invention . Means for Solving Problem K] The present invention prevents the penetration of moisture etc. by uniformly coating a vinyl chloride resin paste on a thin paper and drying it to make it water resistant. The present invention relates to a method for producing a water-resistant decorative sheet in which a printed layer is provided on a vinyl chloride resin paste layer and, if necessary, a surface protective layer is provided on the printed layer. The thin paper used in the present invention has a basis weight of 20 to 50 g/
It is preferable to use thin paper of about 23 to 30 g/wt, which is a single-gloss base paper mainly made using a Yankee type paper machine. In the present invention, in order to impart water resistance, a high viscosity sol-like vinyl chloride resin paste, which is kneaded with a plasticizer, a stabilizer, and, if necessary, titanium oxide, etc., is applied to the thin paper and dried. As a water-resistant resin, vinyl chloride resin paste does not take too long to harden and is easy to handle. It is suitable because it is cheap and relatively flame retardant. The coating methods for vinyl chloride resin paste on 9M paper include gravure coating, roll coating, and comma coating. It can be carried out using known methods such as air knife coating and silk screen, and the film thickness is 10 to 10 mm for the purpose of the present invention.
Approximately 20μ is appropriate. The coating surface must be smooth and free of pinholes. The thin paper coated with the vinyl chloride resin paste as described above is made into a decorative sheet by providing a normal printing layer and, if necessary, a surface protective layer on the printing layer. In addition to coloring and pattern printing, the printing layer may also be printed using raised ink containing a foaming agent, and by such means, a water-resistant decorative sheet with a three-dimensional appearance can be obtained. can be manufactured. To print the pattern, use a normal ink composition,
Specifically, a vehicle is used in which a pigment or dye flavoring agent, a plasticizer, a stabilizer, other additives, a solvent, or a diluent are kneaded. Vehicles include, for example, cellulose derivatives such as ethyl cellulose, ethyl and droxyethyl cellulose, cellulose acetate propionate, cellulose acetate, polystyrene, styrene resins and styrene copolymer resins such as polyα-methylstyrene, polymethyl methacrylate, and polymethacrylic acid. Acrylic or methacrylic resin alone or copolymer resin such as ethyl, polyethyl acrylate, polybutyl acrylate, rosin, rosin-modified maleic acid resin, rosin-modified phenolic resin, rosin ester resin such as 9-polymerized rosin, polyvinyl acetate resin . Coumaron resin, vinyl toluene resin, vinyl chloride resin,
One or more of polyester resins, polyurethane resins, butyral resins, etc. can be selected and used, and in addition, pigments or coloring agents for dyeing, stabilizers, plasticizers, dispersants, other additives, solvents or diluents. The mixture is kneaded and used as ink. In order to print and form ordinary patterns using these ink compositions, known printing methods such as gravure printing, offset gravure printing, silk screen printing, offset printing, electrostatic printing, and jet printing can be used. Can be used. The surface protective layer is provided for the purpose of protecting the pattern printed as described above from abrasion, adjusting the gloss of the surface, and increasing the feeling of handling. The resins used are unsaturated polyester resin, diallyl phthalate resin, epoxy resin, and phenol resin. Examples include urethane resin, melamine resin, amino alkyd resin, and preferably acrylic urethane resin,
A polyurethane resin or an aminoalkyd resin is used, and the coating amount is 2 to 30 g/TIt (dry), preferably 3 to 10 g/rI1. (when dry). An inorganic substance such as silica can be added to the resin as a matting agent, if necessary.

ートは建材として好適なものである。The vinyl chloride resin layer provided according to the present invention prevents moisture from penetrating from the surface of the decorative sheet into the M-leaf paper serving as the base material, thereby improving the water resistance of the decorative sheet. K Example 1 An example of the structure of a decorative sheet obtained by the method of the present invention is shown in the drawings. In the drawing, 1 is a thin paper that can be used as a base material, and 2 is a vinyl chloride resin paste layer. In this example, a flat ink layer 3, a pattern ink layer 4, and a foamed embossed printing layer 5 are provided on the resin paste layer 2 by printing. Furthermore, a surface protective layer 6 is formed on the surface of the decorative sheet. Next, a method for manufacturing the decorative sheet shown in the drawings will be described with reference to examples. Example A 28g/rlL thin paper (manufactured by Oma Tokushu Paper Co., Ltd., H-28) was used as the base paper, and a vinyl chloride resin paste with the following composition was applied to the surface of the thin paper using a 100μ solid gravure plate, and after gravure coating, it was coated smoothly. The surface was smoothed using Ingvar. The drying time was 180°C for 15 seconds. Vinyl chloride resin paste composition Polyvinyl chloride resin 100 ffi ffi parts Calcium carbonate 50 parts Total titanium oxide 15 parts by weight Plasticizer 65 parts by weight Stabilizer 3 layers\hanging part Vinyl chloride resin paste was applied on the base material 1 as described above. Layer 2 is coated, and an ink having the following composition is further coated to form a petain ink layer 3. Print pattern ink layer 4.

Heat at 140°C for 10 seconds to dry the whole thing,
The raised foam pattern layer is foamed to an average height of 150 to 2
A decorative sheet having a 00μ convex pattern was obtained. When water droplets were placed on the surface of the obtained decorative sheet, it was covered clockwise and left for 24 hours, no water penetrated to the back surface, and it was confirmed that it maintained good water resistance. Effects of the Invention The decorative sheet according to the present invention prevents moisture from penetrating into the base material, which has water absorbency and breathability, from the surface of the decorative sheet by coating the thin paper that is the base material with vinyl chloride resin paste. Therefore, a water-resistant decorative sheet can be obtained. The vinyl chloride resin paste used in the present invention has a short curing time and is easy to handle, is inexpensive, and is flame retardant, so the decorative sheet of the present invention is suitable as a building material.
