Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to an iridescent laminate and gold and silver thread.

[Prior art/problems to be solved by the invention] Iris-wrapped gold and silver threads have been known in the past, which are obtained by slitting an iris-colored laminate made of a polyester film or the like provided with a thin film layer of an iris compound such as zinc sulfide. .

However, such conventional iris-wrapped gold and silver threads exhibit monotonous iris colors and poor luster, and also have practical properties as gold and silver threads (resistance to processing such as bleaching, dyeing, scouring, etc.).
There were also problems such as poor washing resistance.

In view of the above-mentioned points, the present invention aims to provide an iris-colored laminate and a iris-wrapping gold and silver thread that exhibits a rich variety of iris colors, has excellent luster, and has excellent practical properties. .

[Means for Solving the Problems] The present invention provides a transparent iris layer formed by laminating an iris compound thin film layer and a transparent resin layer having a non-uniform thickness on one side of a transparent plastic film. A laminate comprising: the iris layer on the plastic film;
The present invention relates to an iris-colored laminate characterized in that it is formed by sequentially laminating a transparent resin undercoat layer and a transparent inorganic protective layer.

Furthermore, the present invention relates to an iris-wrapped gold and silver thread formed by slitting the iris-colored laminate.

[Function and Examples] The iris-colored laminate of the present invention will be explained based on the drawings.

FIG. 1 is a schematic partial cross-sectional view showing an embodiment of the iris-colored laminate of the present invention. In Figure 1, (1) is a transparent plastic film, on one side of which a transparent resin undercoat layer (2) and a transparent inorganic protective layer (3) are provided in this order, and on top of that an iris layer (4). It is provided. The iris layer (4) of this example is made by laminating a transparent resin layer (4b) having a non-uniform thickness on an iris compound thin film layer (4a).

FIG. 2 is a schematic partial cross-sectional view showing another embodiment of the iris-colored laminate of the present invention. In the iris-colored laminate shown in FIG. 2, a transparent resin undercoat layer (2) and a transparent inorganic protective layer (3) are provided in this order on one side of a plastic film (1), and an iris layer (4) is provided on one side of the plastic film (1). ), but the iris layer (4) of this example has an iris compound thin film layer (4a) on top of a transparent resin layer (4b) having a non-uniform thickness.
A transparent resin top coat layer (5) is further provided on the thin film layer (4a).

When the iris layer (4) is laminated in the following order from the plastic film (1) side to the iris compound thin film layer (4a) and the resin layer (4b) having an uneven thickness, as shown in FIG.
Since the resin layer (4b) is the uppermost layer, there is no need to provide a resin top coat layer (5).

As shown in Figure 2, the lamination order of the iris layer (4) is from the plastic film (1) side to the resin layer (4) which has an uneven thickness.
b) In the case of the iris compound thin film layer (4a), the iris compound thin film layer (4a) becomes the top layer, and therefore it is not used in applications that require protection of the thin film layer (4a), such as gold and silver thread applications. If necessary, a resin overcoat layer (5) is provided for protection.

In the iris-colored laminate of the present invention, the iris color can be changed both on the plastic film (1) side and on the opposite side.

In the present invention, the iris layer (4) is an iris compound thin film layer (
4a) and a transparent resin layer (4b) having a non-uniform thickness are laminated, so the iris is rich in color and has excellent gloss.

In addition, by providing the iris layer (4) on the plastic film (1) via the resin undercoat layer (2) and the inorganic protective layer (3), the iris layer (4) and the plastic film (1) can be The adhesion of the iris is improved, and therefore resistance to processing such as bleaching, dyeing, and scouring, as well as washing resistance, is extremely good, and deterioration or loss of iris color due to these treatments is prevented. This effect is especially true for the first
This is remarkable in the case of the embodiment in which the iris compound thin film layer (4a) is directly laminated on the inorganic protective layer (3) as shown in the figure.

Furthermore, since the inorganic protective layer (3) has a higher refractive index than the resin layer, it has the effect of making the color of the iris layer (4) richer and stronger, and improving the gloss. Conventionally known iris-colored laminates in which an overcoat resin layer is laminated on a thin film layer such as zinc sulfide have the disadvantage that the gloss and color development vary greatly depending on the thickness of the thin film layer, but in the present invention, inorganic By laminating the protective layer (3), the refractive index can be changed to a high value regardless of the thickness of the iris compound thin film layer, so that it also has the effect of improving gloss and color development.

The transparent plastic film (1) used in the present invention is not particularly limited, and films conventionally used for applications such as gold and silver thread, such as polyester, polyamide, polyamideimide, polyethylene, polypropylene, cellulose acetate, polycarbonate, and polychloride, can be used. Resin films such as vinyl and fluororesin are used as appropriate. The thickness of transparent plastic film is usually 4~loO
It is appropriately selected from the range of 6 to 50 Atm, more preferably from 6 to 50 Atm. In the case of gold and silver thread applications, the mechanical properties of the transparent plastic film almost directly influence the mechanical properties of the gold and silver thread, thereby determining the weavability and texture, so they are appropriately selected and used in consideration of these factors.

Further, in the present invention, the thickness of the transparent resin undercoat layer (2) is usually 0. O range of 1 to 5, more preferably 0.02 to 3
selected from a range of The thickness of the transparent resin undercoat layer is 0.0
If it is less than 1 left, the resistance to washing, bleaching, dyeing, scouring, etc. will be poor, which is not preferable. On the other hand, if it exceeds 5I, it becomes stiff as a whole in applications such as gold and silver threads and lacks weavability and texture, which is not preferable.

As the resin for forming the transparent resin undercoat layer (2), any of various resins such as thermoplastic resins, thermosetting resins, electron beam curable resins, and ultraviolet curable resins can be used. For example, acrylic resins, Styrenic resin, acrylic-styrene copolymer, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resin, urea resin, melamine Preferred are resins such as urea-melamine resins, epoxy resins, alkyd resins, aminoalkyd resins, rosin-modified maleic acid resins, etc. alone or in mixtures.Curing resins are particularly preferred.

The transparent resin undercoat layer (2) is formed by applying an organic solvent solution, aqueous solution, etc. of the resin to a uniform thickness by a conventional coating method such as gravure coating or spray coating, and drying (thermosetting). In the case of resins, electron beam curable resins, ultraviolet ray curable resins, etc., this is done by curing).

The inorganic protective layer (3) in the present invention is a transparent thin film layer of an inorganic substance that can improve the adhesion between the resin undercoat layer (2) and the iris layer (4), and is made of, for example, silicon, silicon oxide (Sj
O,5i02,S,0x(x-0,3~2, <0.7~1.8)), aluminum oxide (M2C
Thin film layers such as h, /V20X (x-1~3) are suitable. As mentioned above, the thin film layer of these inorganic substances also has the effect of enriching the color of the iris layer (4) and further improving the gloss. Further, since the silicon oxide thin film layer itself exhibits an iris color, the resulting laminate has a better iris color.

The inorganic protective layer (3) usually ranges from 25 to 1000 r+m,
More preferably, the thickness is uniform in the range of 30 to 500 nm. If the thickness of the protective layer (3) is less than 25 nm, the effect of preventing deterioration of the iris color against various treatments will not be sufficient;
If it exceeds 1,000 nm, the transparency is decreased, cracks are more likely to occur, and the resistance to various treatments is decreased, which is not preferable.

The inorganic protective layer (3) may be formed using a corresponding evaporation source material by a conventional vapor deposition thin film forming method such as a resistance heating method, a high frequency induction heating method, or an electron beam heating method. As the evaporation source material, silicon is used for the silicon protective layer, and silicon is used for the silicon oxide protective layer.
O9Sj 02, or a mixture thereof, plus Qi and S
A press-molded material such as a mixture of L 02 or, in the case of an aluminum oxide protective layer, a press-molded material of M2O3 may be used as appropriate.

The thickness of the inorganic protective layer (3) is a value measured using a crystal oscillator thickness monitor.

Examples of the iris compound thin film layer (4a) in the present invention include thin film layers of zinc sulfide, bismuth oxide, antimony oxide, titanium oxide, silicon oxide, zinc oxide, magnesium fluoride, potassium fluoride, cryolite, and the like. Zinc sulfide and bismuth oxide (Bib.

Bi2O3, B1204, Bi2O5, Bi20x (
x=2-5)) and antimony oxide [5b203
．． 5b204Sb20s, 5b20x (x-2~5
) is preferable.

The iris compound thin film layer (4a) has a uniform thickness, usually in the range of 5 to loOnm, more preferably in the range of 20 to 80nrA. If the thickness of the thin film layer is less than 5 nm, the iris gloss cannot be changed, which is not preferable. On the other hand, if it exceeds 1100n, the iris will have poor luster and cracks will appear more easily.
Resistance to treatments such as scouring also decreases, which is undesirable.

The iris compound thin film layer (4a) may be formed by a conventional vapor deposition thin film forming method such as a resistance heating method, a high frequency induction heating method, or an electron beam heating method using a corresponding evaporation source material.

There are no particular limitations on the evaporation source material used to form the iris compound thin film layer (4a). For example, as an evaporation source material for forming a zinc sulfide thin film layer, press molding of zinc sulfide (Zn5) powder with a purity of 70% by weight or more can be used as appropriate; however, zinc sulfide powder with a purity of 90% by weight or more can be used. Press-molded materials are more preferably used. As the evaporation source material for forming the bismuth oxide thin film layer, a press-molded bismuth oxide powder with a purity of 80% by weight or more can be used, or a press-molded bismuth oxide powder with a purity of 90% by weight or more can be used. is more preferably used. As the evaporation source material for forming the antimony oxide thin film layer, any press-molded antimony oxide powder with a purity of 80% by weight or more can be used, but antimony oxide powder with a purity of 90% by weight or more is press-molded. is more preferably used.

The thickness of the iris compound thin film layer is a value measured using a quartz crystal resonator film thickness monitor.

The resin layer (4b) having a non-uniform thickness usually has a thickness of 0.01~
The thickness is nonuniform within a range of 5 times, more preferably within a range of 0.02 to 3 times. The thickness of the resin layer is 0. OL, c
If it is less than n, almost no iris luster will be obtained, which is not preferable.

On the other hand, if it exceeds 5 um, the iris luster will be rather poor, and furthermore, in the case of applications such as gold and silver threads, it will become stiff as a whole and lack weavability and texture, which is not preferable. The degree of non-uniformity in the thickness of the resin layer (4b) (difference between thick and thin parts of the resin layer, hereinafter referred to as non-uniformity) is from 0.1 to
It is preferable to set it to about 1 left. Heterogeneity is 0.11Ar
If it is less than 1, the color development will be monotonous and it will be difficult to change the rich iris color, while if it exceeds IJsl, the color development will become pale, which is not preferable. The period of non-uniform thickness (referring to the distance between adjacent thick parts or the distance between adjacent thin parts) corresponds to the density of the iris pattern, and is usually preferably about 0.5 to 20 crn, but within this range It is not limited to. Note that the period may or may not be constant. The non-uniform pattern is usually a striped pattern, but is not limited to this.

Various resins such as thermoplastic resins, thermosetting resins, electron beam curable resins, and ultraviolet curable resins can be used as the resin for forming the transparent resin layer (4b) having a nonuniform thickness. , for example, arykyl resin, styrene resin, acrylic-styrene copolymer, vinyl chloride resin,
Vinyl acetate resin, vinyl chloride-vinyl acetate copolymer,
Polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resin, urea resin, melamine resin, urea-melamine resin, epoxy resin, alkyd resin, amino alkyd resin, rosin-modified maleic acid resin, etc. They are preferably used alone or in mixtures.

The transparent resin layer (4b) having a non-uniform thickness is formed by applying an organic solvent solution, aqueous solution, etc. of the resin to a non-uniform thickness using a conventional coating method such as a gravure coating method or a spray coating method. , drying (curing in the case of thermosetting resins, electron beam curable resins, ultraviolet curable resins, etc.).

The thickness of the transparent resin top coat layer (5) in the present invention is usually 0.
It is selected from the range of 0.01 to 5 times, more preferably 0.02 to 3 times. The thickness of the transparent resin top coat layer is 0.01. a
If it is less than m, the resistance to each of the above-mentioned treatments will be insufficient, which is not preferable. On the other hand, if the number exceeds 5 doors, it is not preferable for applications such as gold and silver threads, since the whole becomes stiff and lacks weavability and texture.

Various resins such as thermoplastic resins, thermosetting resins, electron beam curable resins, and ultraviolet curable resins can be used as the resin for forming the transparent resin top coat layer (5).
For example, acrylic resin, styrene resin, acrylic resin, etc.
Styrene copolymer, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resin, urea resin, melamine resin, urea-melamine Preferably used are resins such as epoxy resins, alkyd resins, aminoalkyd resins, rosin-modified maleic acid resins, and the like alone or in mixtures. In particular, curable resins are preferably used.

The transparent resin top coat layer (5) is formed by coating the resin to a uniform thickness using a conventional coating method such as a gravure coating method or a spray coating method using a solvent solution, an aqueous solution, etc., and drying (heating). Cured in the case of curable resins, electron beam curable resins, ultraviolet ray curable resins, etc.)
It is done by doing.

In addition, the transparent resin undercoat layer (2), the transparent resin layer (4b) having a non-uniform thickness, and the transparent resin topcoat layer (S is a dye and/or pigment as appropriate as long as it does not impair transparency). May be colored.

In the present invention, the two laminates may be laminated using an adhesive with the plastic film (1) side facing inside or the opposite side facing inside to form a two-bly structure. If a two-ply structure is used with the opposite side of the plastic film (1) inside, the gold and silver thread can withstand not only scouring treatment but also georgette treatment.

As the adhesive, a urethane resin-based adhesive, an epoxy resin-based adhesive, a polyester resin-based adhesive, an acrylic resin-based adhesive, a synthetic rubber-based adhesive, or the like is appropriately used.

The iridescent laminate of the present invention is used for packaging materials, labels, sequins, poster buttons, pendants, and various other decorative materials, and is particularly suitable for use with gold and silver threads.

The iris-wrapping gold and silver thread can be obtained by slitting the iris-colored laminate into a suitable width, for example, 0.15 to 2 mm.
