[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative paper material which can be suitably used as a bag or a box for packaging, and other various decorative paper materials.
The present invention relates to a decorative paper material using a commercially available glitter film.

[0002]

2. Description of the Related Art Bright film (Aurora film)
Is a very beautiful film that is formed by superimposing and integrating transparent films with different crystallinity to give an aurora-like or rainbow-like illusion of illusion by the refraction and polarization of light. , Sold by Marl of the United States. It is known that when this glittering film is bonded to a base paper made of various types of paper or Japanese paper, or when various embossing processes are performed after the bonding, an elegant decorative paper can be obtained.

[0003]

The decorative paper using the above-mentioned glittery film has a hydrophobic film on its surface, and therefore does not have an adhesive property with an aqueous glue. It has a major disadvantage that it cannot be processed into a box. Also, even when bonded with a solution type adhesive, the curl is strong and the handleability is poor, and the hydrophobic surface of the glittering film does not accept aqueous ink or offset ink, and there is no printability, especially the suitability of offset printing, There is a problem that the trademark and the contents display cannot be printed.

[0004] Therefore, even decorative paper that emits beautiful aurora-like radiance does not have bag-making and box-making properties with an automatic machine, and there is no means for printing in large quantities. The box is inevitably processed by hand, making it inefficient and very costly. Furthermore, the paper material on which the glitter film is affixed has a very strong light brightness, and it is crisp as a glitter. is there. Due to these drawbacks, the decorative paper of this type in the past has a very limited application range.

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the problems caused by the brilliant film of the decorative paper as described above, and has good adhesiveness with an aqueous paste and without curling. A bag making machine or a box making machine can process a large amount of bags or boxes, and it has printability and can apply any characters, figures and patterns, and the light brightness is moderately suppressed. The purpose of the present invention is to provide a decorative paper material having a very high usefulness.

[0006]

In order to achieve the above object, various resin coatings were tried at first, but good results were not obtained. As a result of further investigation, it was important to prevent curling. It is conceived that the three-layer structure, that is, the structure of “paper + film + paper” is excellent as a form, and it is considered that making this surface layer paper improves the adhesiveness and printability. It has been found that a very suitable decorative paper material can be obtained by sticking a glass paper, which is a transparent paper and reduces the light brightness appropriately.

That is, in the present invention, any coloring or pattern
A glitter film as an intermediate layer on the base paper
The gist of the present invention is a decorative paper material characterized by laminating glassine paper or translucent paper similar to glassine paper as its surface layer.

The present invention will be described with reference to the drawings. FIG. 1 is a partially enlarged sectional schematic view of the paper material of the present invention. As shown in this figure, the present invention is obtained by laminating a glitter film (2) as an intermediate layer and a glassine paper (3) as a surface layer on a base paper (1).

The base paper (1) in the present invention may be arbitrarily selected according to the purpose. A thick paper is suitable for a box, and a slightly thin paper is used for a bag. Flexible paper is desirable. The base paper (1) may be appropriately colored or patterned. This coloring, for example, by coating
When colored in white, black, red, yellow, green, blue, and the like, various aurora-like and rainbow-like expressions can be achieved in combination with the glittering film (2) of the intermediate layer. In the case of a pattern, if various print patterns are applied by gravure printing or the like, a very complicated phantom pattern can be obtained in combination with the glittering film (2).

Also, the glitter film of the present invention (2)
As described above, "Aurora Film" sold by Marl Company of the United States is usually a film having a thickness of 10 to 20 .mu.m.

The most important feature of the present invention is that glassine paper (3) is used as the surface layer, which results in a three-layer structure of "base paper + bright film + paper", and curl prevention is obtained. In addition, since the surface layer is made of a paper material, affinity with an aqueous paste, an aqueous ink, an offset ink, or the like is obtained, and the translucency of the translucent film moderately lowers the brightness of the glittering film (2). It is.

The glassine paper (3) is a so-called loose sulfuric acid paper. The sulfurous acid pulp is highly viscous pulverized with a stone roll beater to form a paper, which is made glossy through a super calender while being translucent. And usually has a basis weight of 20 to 35 g / m ² . Although the glassine paper (3) was the most suitable as the translucent paper in the experiment of the present inventor, other translucent papers such as tracing paper and “Dreep W” commercially available from Honshu Paper Co., Ltd. "(basis weight 27g / m ^2),
"Top color" marketed by Shirakawa Paper Co., Ltd.
(14 g / m ² ).

[0013] The present invention is a method for producing decorative paper, that is, base paper (1), brilliant film (2), and glassine paper (3).
As the laminating means, the three members may be laminated at the same time, but first, the glittering film (2) is laminated with the glassine paper (3), and then the glittering film (2) is attached to the base paper. The method of bonding (1) is the most preferable. The adhesive for these laminations may be a solution type synthetic resin adhesive, for example, a polyurethane resin,
An adhesive such as a vinyl acetate resin or an acrylic resin can be suitably used. It is needless to say that the decorative paper material thus obtained may be appropriately embossed.

[0014]

Example: Aurora film having a thickness of 12 μm manufactured by Marl, USA and glassine paper having a basis weight of 30 g / m ² manufactured by Honshu Paper Co., Ltd. were bonded to a polyurethane resin adhesive manufactured by Takeda Pharmaceutical Company (solid content: 45%). Was dry-laminated at a temperature of 80 ° C. and a speed of 30 m / min using 10 g / m ^{2 of a} wet material.

On the other hand, “Hamayu” (pure white; basis weight 50 g / m ² ) manufactured by Kishu Paper Co., Ltd. was prepared as a base paper, and 100 parts by weight of a white water-based paint (pigment solid content 50%) was prepared. A mixture adjustment liquid consisting of 50 parts by weight of solid content 50%) and 25 parts by weight of poval (solid content 25%) was heated at a temperature of 130.
The entire surface was coated (wet 20 g / m ² ) and colored at 60 ° C. and a speed of 60 m / min.

The aurora film surface of the dry-laminated laminating material is coated on the above-mentioned colored base paper by using the same polyurethane resin adhesive as above at a wet ratio of 10 g / m ² at a temperature of 80 ° C. and a speed of 25 m. / Min dry drying. As a result, a curl-free three-layer decorative paper material in which the aurora film was sanded on the intermediate layer and the surface layer was glassine paper was obtained. The decorative paper material had excellent printability and could be easily printed by ordinary offset printing.

Further, silk paper patterns, fir patterns,
When various embossing processes (temperature: 80 ° C., pressure: 12 tons, speed: 25 m / min) such as satin finish, crepe pattern, and vine pattern were performed, a very beautiful decorative paper material was obtained. This decorative paper material has a surface light brightness that is moderately lower than the surface of Aurora Film only, it has an elegant luster, and it has good adhesion with aqueous glue and it is suitable for bag making machines and box making machines. And could be easily processed into bags and boxes.

[0018]

[Effects of the Invention] As described above, the present invention solves the conventional disadvantages at a glance by pasting glassine paper on the surface layer. The effects are as follows. (A) Despite being a decorative paper material using a glitter film (Aurora film), it has an adhesive property with an aqueous paste, and is excellent in bag making and box making. (B) It also has an affinity for aqueous inks, offset inks and the like, is excellent in printability, and can print any trademark, contents display, and the like. (C) Since it has a three-layer structure of “paper + film + paper”, it is easy to handle without curling and is easy to process with a box making machine or a bag making machine. (D) Since the brightness of light on the surface is appropriately suppressed by glassine paper which is a translucent paper, the gloss is very elegant and elegant.

As described above, the present invention has various excellent effects, and as a result, it can be mass-produced into a bag or a box, is easy to print, and has an elegant and elegant appearance. However, this type of decorative paper material is extremely useful because it can be expected to greatly expand its applications.
