Description

[Detailed Description of the Invention] Conventionally, it has been known to print a glossy resin undercoat on sealed Japanese paper in a pattern using a gravure cylinder or the like, and then apply metal vapor deposition to the entire surface to create a patterned metal vapor deposited product. ing. It is also known that printing paste is printed in a pattern on textiles, and then metal vapor deposition is applied to the entire surface to create patterned metal vapor deposition products. It is necessary to apply a primer or printing paste to the fabric in a pattern, and this requires a gravure printing machine or a textile printing machine, which increases equipment costs.In addition, the metallic luster of the base part and the metallic luster of the pattern part are high. There is a problem that the difference is so large that it is difficult to change the delicate contrasting metallic luster pattern.

In view of the above-mentioned points, the present invention provides a patterned metal vapor deposited product having a metallic luster pattern of fibrous foundation coat without requiring the step of applying an undercoat or printing paste in a patterned manner.

That is, the present invention provides a patterned gold-metal vapor-deposited product, which is characterized in that a nonwoven fiber aggregate with a coarse structure is heat-sealed on at least one side of a flexible base material, and a metal vapor-deposited layer is provided on the entire surface thereof. Regarding.

Next, the patterned metal vapor deposition product of the present invention will be explained based on the drawings. Fig. 1 is a partial plan view showing an example of the metal vapor deposited product of the present invention, and Fig. 2 is a partially enlarged sectional view thereof◇ The metal vapor deposited product shown in Figs. Material (1
) is heat-sealed with a coarsely textured nonwoven fiber aggregate (2) on one side, and on top of that is metal vapor-deposited Ml (4) on the entire surface.
0(S) is the fiber constituting the fiber aggregate (2).The fiber (8) originally has a substantially circular cross-sectional shape due to heating and pressure during heat fusion. Even though it is almost rectangular in shape and its upper surface is smooth,
The part of the metallized layer (4) located on the fiber (3) (
The metallic luster in 5) is the part (6) of the metal vapor deposited layer (4) located on the base material (1) such as Japanese paper, that is, the base part (6).
It has a superior metallic luster.

However, the patterned metal vapor deposition product of the present invention has a fiber portion (5
) The contrast between the intricate pattern of excellent metallic luster and the slightly dull metallic luster of the base gives it a delicate and unique metallic luster pattern. Furthermore, in the present invention, instead of applying an undercoat or printing paste in a pattern on the base material as in the past, the nonwoven fiber aggregate (2) is simply layered on the base material (1) and thermally fused. Since a pattern is formed by this process, an intricate metallic luster pattern can be formed very easily.

In the present invention, a flexible base material (
The fiber aggregates (2) may be heat-sealed on both sides of 1), and then a metal vapor deposited layer (4) may be provided on the entire surface so that both sides have a metallic luster pattern.

Further, as shown in FIG. 4, a flexible base material (1) having a structure in which a flexible base material (1) is bonded via an adhesive layer (7),
The metallic luster pattern may be applied on both sides.

A metal vapor deposited product having such a structure is usually produced by preparing a metal vapor deposited product in advance as shown in FIG. 2 and forming it into a two-ply structure.

Further, in order to improve the durability of the metal vapor deposited layer (4), an uncolored or colored transparent top coating layer may be provided on the entire surface of the metal vapor deposited layer (4).

As the flexible base material (1), synthetic resin films, papers, woven fabrics, laminates thereof, etc. can be used. Examples of synthetic resin films include polyester, acrylic resin, polyvinyl chloride, polypyrene, polyethylene, etc. All ordinary films are used, and the thickness is 2 to 100 μm.
Japanese paper, Western paper, synthetic paper, etc. are all used as papers with a basis weight of about 8 to 80 g/m2. In particular, Japanese paper for gold and silver threads is preferably used. Woven fabrics include polyester fiber cloth, acrylic fiber cloth,
Any of ordinary synthetic fiber cloths such as rayon fiber cloth, vinyl fiber cloth, cotton cloth, semi-synthetic fiber cloth, natural fiber cloth, etc. can be used. In the case of paper, one coated with a sealing resin may be used. As the flexible base material (1), Japanese paper is particularly preferable because it can be used to create a metallic luster pattern with delicate contrast. , polyolefin-modified polyamide fibers, polyester fibers, acrylic fibers, polyurethane fibers, polyvinyl chloride fibers, vinylon fibers, and other heat-sealable synthetic fibers with a nonwoven structure.

It is preferable to use one with a coarse structure so that metal vapor deposition can be performed in the gaps between the fibers after heat-sealing. From this point of view, fibers with a fineness of about 0.5 to 70 denier and a basis weight of 5 to 70 denier are used.
A material having a weight of about 120 g/m2 is preferably used. The cross-sectional shape of the fiber is not particularly limited, and may be circular, oval, rectangular,
Any other irregular shape may also be used. As described above, in the present invention, the cross-sectional shape of the fibers does not particularly matter because the fibers become flat when the fiber aggregate (2) is thermally fused. Specific examples of such fiber aggregates (2) include:
For example, Dynasty LNS 0010.0011.00
12.0013.0014.0015.0016.00
17.0018.0019.0020 (all of the above are made of polyamide fiber manufactured by Kureha Seni ■), etc. ◇ Metals for the metal vapor deposition layer (4) include aluminum, silver, platinum, gold, nickel, and copper. , titanium, and other metals that can be vapor-deposited are used. These are made into a metal vapor deposited layer by a normal thin film forming method such as a vacuum deposition method, a sputtering method, or an ion blating method. The thickness of the metal vapor deposition layer is usually 30~
15 (approximately 1 mμ).

The metal vapor-deposited product of the present invention is produced by stacking the fiber aggregate (2) on the flexible base material (1) and applying heat and pressure using a hot roll press or the like to form the fiber aggregate (2) on the base material (1). is heat-sealed, and then metal is vapor-deposited on the entire surface to form a metal vapor-deposited layer (
4) and then optionally providing a top coating layer.

The patterned metal vapor-deposited product of the present invention may be cut into an appropriate size and used for decoration by pasting it on other articles.
(In that case, the metal vapor-deposited product itself may be provided with an adhesive layer.) Alternatively, it may be made into slit thread and used as gold and silver thread.1 It may also be used as a foil.

Next, the present invention will be explained with reference to Examples.

Example 1 A melamine-alkyd resin was applied to Japanese paper with a tsubo fi of 21 g/rn2 at a dry coating amount of 3 g/rn2 to seal it.

Dynatsu LNS0010 is applied to the sealing treated side of the Japanese paper.
(Polyamide with a fineness of 10 denier and approximately circular cross section) A non-woven fiber aggregate consisting of 11 fibers, with a basis weight of 60 μm
), and pass it through a hot roll press heated to 140 to 170°O, and place it on washi paper.
10 was heat-sealed. Next, Dynatsuku IJS 001 (
Aluminum was vacuum-deposited over the entire surface of the Japanese paper to which 1 was heat-sealed to form an 80 μm thick aluminum deposited layer, and a 1 μm thick top colting layer made of melamine-alkyd resin was formed thereon.

The metal vapor-deposited product thus obtained was extremely beautiful, with a bright silvery-white lustrous fiber pattern standing out on a slightly dull silvery-white lustrous background.

Example 2 A metal vapor-deposited product was obtained in the same manner as in Example 1, except that Japanese paper without sealing was used instead of Japanese paper.

In this product, the contrast between the metallic luster of the base portion and the metallic luster of the fiber portion was even clearer than in Example 1.
