(Industrial Application Field) The present invention relates to a matte vapor-deposited sheet, and the matte vapor-deposited sheet obtained by the present invention is used for packaging materials and the like. (Prior Art) Conventionally, aluminum foil laminated paper has been used as a packaging material, particularly a cigarette packaging material, as a packaging material that has excellent moisture resistance and aroma retention properties, and has a luxurious feel due to the color effect unique to metal. However, with recent advances in vapor deposition technology, aluminum vapor-deposited paper has been developed that has properties required for packaging materials, such as moisture resistance and aesthetics, that are similar to those of aluminum foil-laminated paper, and it is now being used as a packaging material for cigarettes. However, since these metallized papers have a coating layer (undercoat lacquer layer) on the paper and then a metal vapor deposition layer on top of that, they have a strong metallic luster, which is different from the conventional matte aluminum foil laminated paper. There is a demand for matte vapor-deposited paper with a weak metallic luster in order to exhibit an appearance different from the luxurious metallic luster that has lost its luster. (Problems to be Solved by the Invention) Matte vapor-deposited paper with weak metallic luster can be obtained by directly providing a metal vapor-deposited layer without forming an undercoat lacquer layer on paper. Since it lacks an undercoat lacquer layer, it has the disadvantage that its moisture resistance is significantly reduced and its appearance is not a matte metallic luster but a dark hue. The present inventors provide a matte vapor-deposited sheet that is cheaper than aluminum foil laminated paper, has properties as a packaging material such as moisture resistance, and has a matte vapor-deposited surface in appearance. (Means for Solving the Problem) The matte vapor-deposited sheet of the present invention is one in which a pine lacquer layer is formed on the top or bottom surface of a metal vapor-deposited layer provided on a base material using a lacquer in which fine powder of an inorganic pigment is dispersed. It is. As the base material used in the present invention, paper is mainly used, but other materials such as plastic film can also be used. The lacquer used to form the pine lacquer layer is one or two of the following: vinyl chloride-vinyl acetate copolymer resin, vinylidene chloride-vinyl chloride copolymer resin, and ethylene-vinyl acetate-vinyl chloride copolymer resin. Examples include those made of the above copolymer resins. These copolymer resins are used for lacquers or paints, and the degree of polymerization and polymerization ratio can be arbitrarily selected depending on the purpose. Each copolymer resin system can be used alone or in combination depending on the purpose. Can be used in combination. Furthermore, fine powders such as calcium carbonate, titanium oxide, aluminum oxide, fly ash, and carbon black are used as inorganic pigments added to these copolymer resins, but the appearance is almost the same as the matte surface of aluminum foil laminated paper. It is preferable to use calcium carbonate in order to obtain excellent moisture-proofing properties. The particle size of these inorganic pigment fine powders is preferably 50 μm or less, and any shape may be used. The best effect is obtained when the amount added is 10 to 30% based on the solid content in the lacquer. When the inorganic pigment fine powder used in the present invention is dispersed in a lacquer, resins, solvents, etc. are adsorbed to the particle surface, forming a colloid, which has good affinity with solvents, is uniformly dispersed, and has good stability. It has a good quality and can be applied uniformly during coating, and the resulting dry lacquer film (pine lacquer layer) is a flexible, translucent film that can be colored or printed if necessary. The matte vapor-deposited sheet of the present invention comprises: (i) forming a pine lacquer layer in which a lacquer made by dispersing fine powder of an inorganic pigment in a copolymer resin solution is coated as an undercoat lacquer on a substrate such as paper or plastic film; (ii) By forming a conventional undercoat lacquer layer on the base material, forming a metal vapor deposition layer thereon, and forming a pine lacquer layer as an overcoat lacquer thereon, (iii) It can be obtained by forming a pine lacquer layer coated as an undercoat lacquer on a base material, and sequentially forming a metal vapor deposited layer and a pine lacquer layer thereon. (Effects of the Invention) The matte vapor-deposited sheet of the present invention is formed by forming a pine lacquer layer made of a lacquer in which fine powder of an inorganic pigment is dispersed on the upper and/or lower surface of a metal vapor-deposited layer provided on a base material. It has a matte appearance and excellent moisture resistance. Furthermore, since the pine tracker layer has flexibility, it can be easily processed such as molding, the moisture resistance is not reduced by such processing, and it has many advantages such as being able to be colored or printed. (Example) The moisture permeability and glossiness of the matte vapor-deposited paper obtained in the following example were measured, and the results are summarized in Table 1. In addition, the moisture permeability and glossiness of conventionally used glossy aluminum foil and matte aluminum foil were also measured using the same method, and these are also shown in Table 1.
Shown in 1. Example 1 Medium-quality coated paper with a basis weight of 54 g/m 2 was used as the base material, and vinyl chloride-vinyl acetate copolymer resin 45, vinylidene chloride-vinyl chloride copolymer resin 41, and ethylene-vinyl acetate-vinyl chloride copolymer resin A mixed solvent 77 consisting of 18.4 parts by weight of a copolymer resin mixed at a ratio of 14 parts (weight ratio), 36 parts of ethyl acetate, 38 parts of methyl ethyl ketone, and 26 parts of toluene (by weight ratio)
Calcium carbonate less than 50μ in resin solution with parts by weight
After applying pine lacquer prepared by adding 4.6 parts by weight (20% based on solid content) as an undercoat lacquer to a thickness of approximately 4 g/m 2 (dry film), A matte vapor-deposited sheet was produced by forming a 350 Å aluminum vapor-deposited layer. Example 2 Using the same medium-quality coated paper as in Example 1 as the base material, 2.3 parts by weight of calcium carbonate (solid) of 50μ or less was added to a resin solution consisting of 20.7 parts by weight of the same copolymer resin as in Example 1 and 77 parts by weight of a mixed solvent. 10% for minutes)
A matte lacquer prepared by adding lacquer is applied as an undercoat lacquer to a thickness of approximately 4 g/m 2 (dry coating), and an aluminum evaporated layer with a thickness of 250 to 350 Å is formed on the surface to produce a matte evaporated sheet. did. Example 3 Using the same medium-quality coated paper as in Example 1 as the base material, 7 parts by weight of calcium carbonate (solid) of 50μ or less was added to a resin solution consisting of 16 parts by weight of the same copolymer resin as in Example 1 and 77 parts by weight of a mixed solvent. A pine lacquer prepared by adding 25% of the lacquer to the base coat was applied to a thickness of approximately 4 g/m 2 (dry coating), and an aluminum vapor-deposited layer with a thickness of 250 to 350 Å was applied to the surface. A matte vapor-deposited sheet was produced. Example 4 Using the same medium-quality coated paper as in Example 1 as the base material, a vinyl chloride-vinyl acetate copolymer resin undercoat lacquer was applied to a thickness of approximately 4 g/m 2 (dry coating). An aluminum vapor deposition layer with a thickness of 250 to 350 Å was formed on the surface. Furthermore, apply the same pine lacquer as in Example 1 as an overcoat lacquer of about 1.0
A matte vapor-deposited sheet was prepared by coating to a thickness of g/m 2 (dry coating).
