Description

[Detailed Description of the Invention] The present invention relates to a gold vapor-deposited gold thread that exhibits the elegant golden color inherent to gold.

Gold vapor-deposited flexible laminate, in which a pure gold vapor-deposited film is applied directly or via an uncoated film to a flexible support such as plastic film or Japanese paper coated with a filler, and a protective film is provided on top of the pure gold vapor-deposited film. Gold-deposited gold thread made by slitting is known. Gold-deposited gold thread is used in various high-quality textiles and knitted fabrics, but the reason why gold-deposited gold thread is preferred for use in luxury goods is that it has the depth and softness of pure gold, as well as its vibrant golden color, which cannot be achieved with other metals. It's for a reason.

However, since gold is expensive, gold vapor-deposited gold thread is also expensive, and if the thickness of the gold vapor-deposited film is 60 mμ or less, the original bright golden color of gold cannot be obtained and the reddish color increases. be.

In view of the above points, the present invention has been developed to create a gold evaporated gold thread that is less expensive than conventional gold evaporated gold thread, and which uses a thinner gold evaporated film (for example, 20 mμ or more and less than 40 mμ) and exhibits a golden color equivalent to pure gold. This is what we intend to provide.

That is, the present invention consists of at least a support, a gold vapor-deposited thin film, and a transparent colored resin film, and the three layers are laminated such that the transparent colored resin film is located on the side where a golden color is desired with respect to the gold vapor-deposited thin film. and a gold-deposited gold thread exhibiting a golden color, characterized in that the transparent colored resin film contains a dye, a fluorescent dye, or a fluorescent pigment having a maximum absorption band in a wavelength range of 460 to 600 mμ.

This invention replaces the transparent uncolored resin film in the conventional gold vapor-deposited gold thread with
It is characterized in that it contains a dye, fluorescent dye, or fluorescent pigment that has a maximum absorption band in the wavelength range of 540 mμ. However, depending on the specific dye, fluorescent dye or fluorescent pigment, 460 ~
By absorbing light in the wavelength range of 600 mμ, especially from 500 to 540 mμ, the light reflected from the thin gold-deposited surface is changed accordingly, and in the case of the fluorescent dye or pigment, the fluorescence As a result of this action, a golden color equivalent to that of conventional thick and thin vapor deposited films can be obtained.

In this way, the gold vapor-deposited gold thread of the present invention has a golden color even though the gold vapor-deposited film is a thin film, so it is cheaper than conventional gold vapor-deposited gold thread, and it has the depth and softness of pure gold as well as a supple golden color. It has the advantage of being colorful.

The gold vapor-deposited gold thread of the present invention is not particularly different from the conventional one except that the specific transparent colored resin film is provided on the side where a golden color is desired with respect to the gold vapor-deposited thin film. The gold-deposited gold thread of the present invention will be explained below with reference to the drawings.

FIGS. 1 and 2 are longitudinal cross-sectional views showing preferred embodiments of the gold-deposited gold thread of the present invention, respectively.

The gold vapor-deposited gold thread shown in FIG. 1 has the specific transparent colored resin film 3 and gold vapor-deposited thin film 2 sequentially provided on one side of a support 1, and if necessary, a protective film 4 is further provided thereon. (hereinafter referred to as gold vapor-deposited gold thread ()
). In this gold vapor-deposited gold thread ( ), a transparent support 1 is used, and the side of the support 1 has a golden color as shown by the arrow.

The gold vapor-deposited gold thread shown in FIG. 2 has a gold vapor-deposited thin film 2 and the specific transparent colored resin film 3 sequentially provided on one side of a support 1 (hereinafter referred to as gold vapor-deposited gold thread). In this gold vapor-deposited gold thread ( ), the plastic film 1 may be transparent or opaque, and has a golden color on the side of the transparent colored resin film 3 as shown by the arrow.

As the plastic film 1, flexible supports such as films of polyester, polyamide, polyamideimide, polyethylene, polypropylene, polycarbonate, polyvinyl chloride, cellulose acetate, etc., and polymer films such as cellophane are usually used. Usually, the plastic film used has a thickness of about 4 to 50 microns. For the gold vapor-deposited gold thread, a colorless and transparent plastic film is used, and polyethylene terephthalate, polycarbonate, polypropylene, cellulose acetate, etc., which have excellent transparency, are particularly preferred. Gold vapor-deposited gold thread () usually consists of a transparent or opaque polymer film, a polymer film and Japanese paper,
Composite films with Western paper and the like are also used. If the plastic film 1 has poor adhesion to the gold vapor-deposited thin film 2, it is preferable to provide an undercoat film in advance. In the case of gold vapor-deposited gold thread, the transparent colored resin film 3 can also have the function of an undercoat film. The thickness of the base coat is usually 0.5-2μ
That's about it. As the resin paint for the undercoat, one or more resins such as acrylic acid lower alkyl ester resin, urethane resin, urea-melamine resin, aminoalkyd resin, unsaturated polyester, and nitrocellulose are used. .

The gold vapor-deposited thin film 2 may be formed by a normal thin film forming method such as a vacuum vapor deposition method, a sputtering method, or an ion plating method, and its thickness is usually determined.
It is 20 mμ or more and less than 40 mμ. Alternatively, after a gold vapor-deposited thin film is once formed on a removable support, this may be transferred and formed. The transparent colored resin film 3 is
It contains a dye, fluorescent dye or fluorescent pigment having a maximum absorption band in the wavelength range of 460 to 600 mμ, especially 500 to 540 mμ. Here, the fluorescent pigment refers to a transparent organic pigment that exhibits fluorescence. When the maximum absorption band of the dye, fluorescent dye or fluorescent pigment is outside the above wavelength range, it is difficult to obtain a golden color. Examples of the specific dyes, fluorescent dyes, or fluorescent pigments include (dye) Neozapon Fast yellow GG (535mμ, mμ) (fluorescent dye) Shinroihi Color FM-12 Green (520mμ, 460mμ) Shinroihi Color FM-15 Lemon Yellow Woo (520mμ, 460mμ) (fluorescent pigment) Shinroihi Color FZ-3045 Lemon Yellow Rowu (535mμ, 460mμ) Shinroihi Color FZ-5012 Green (520mμ, 460mμ), etc. In the above, the first number in parentheses is the maximum absorption wavelength, and the second number is the wavelength of fluorescence. The content of dye, fluorescent dye, or fluorescent pigment in the transparent colored resin film 3 is 3 to 30%.
(% by weight, the same applies hereinafter), particularly preferably 5 to 18%. When the content of dye, fluorescent dye, or fluorescent pigment is less than the above range, the color obtained is close to the color of the gold vapor-deposited thin film itself, and the effect is small.
On the other hand, if the amount exceeds the above range, coloring by the dye, fluorescent dye or fluorescent pigment itself becomes too strong, and in any case, it is difficult to obtain a golden color. As the resin paint for the transparent colored resin film 3, the same resin paint as that for the undercoat film can be used, except that it contains the dye, fluorescent dye, or fluorescent pigment described above. The thickness of the transparent colored resin film 3 is usually about 0.5 to 2 μm.

The protective film 4 is similar to the undercoat film, but
Usually, it may be colored opaquely using a white pigment such as titanium oxide or other pigments.

The gold vapor-deposited gold thread of the present invention can be obtained by providing the gold vapor-deposited thin film 2, the transparent colored resin film 3, and, if necessary, the protective film 4 on the support 1 in the above-mentioned lamination order. A piece of Japanese paper or the like may be further attached to the protective film 4 side of the money vapor-deposited gold thread (2) using an adhesive. Alternatively, the gold vapor-deposited gold threads () and () may be laminated together with an adhesive with the opposite side of the gold-colored side facing inside to form a two-ply structure so that both sides are coated with the golden color.

The gold-deposited gold thread of the present invention may be used as it is as a flat gold thread, or it may be used as a twisted gold thread by twisting it with other threads such as rayon, silk, cotton, Tetoron, nylon, etc. You can.

Next, the gold vapor-deposited gold thread of the present invention will be explained with reference to Examples and Comparative Examples.
