Description

[Detailed description of the invention] [Industrial application field] The present invention relates to iridescent gold and silver threads for georgette processing.

[Prior Art/Problems to be Solved by the Invention] Iris-colored 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-colored gold and silver threads have a monotonous iris color and poor luster, and also have poor practical properties as gold and silver threads (resistance to processing such as bleaching, dyeing, scouring, or washing resistance). There were problems such as inferiority.

In particular, when processed under harsh conditions such as georgette processing, the iris color and luster deteriorate, making it almost unusable.

In view of the above points, the present invention aims to provide an iris-colored gold and silver thread that exhibits rich iris colors, has excellent luster, and has excellent practical properties that can withstand georgette processing.

[Means for Solving the Problems] The present invention provides a transparent resin undercoat layer, a first antimony oxide thin film layer having a non-uniform thickness, a transparent resin intermediate layer and a first antimony oxide thin film layer on one side of a transparent plastic film. An iris color for georgette processing, which is made by slitting two laminates in which antimony oxide thin film layers (2) are provided in this order, with the transparent plastic film on the outside via an adhesive layer. Regarding gold and silver thread.

The present invention further provides a rainbow formed by slitting two sheets of a laminate in which a transparent resin topcoat layer is provided on the second antimony oxide thin film layer of the laminate, and bonded together via an adhesive layer as described above. Regarding colored gold and silver thread.

[Operations and Examples] The iris-colored gold and silver thread for georgette processing of the present invention does not reduce its iris color and luster even under the harsh conditions of georgette processing, and is particularly suitable for georgette processing.

The iris-colored gold and silver thread for georgette processing (hereinafter referred to as iris-colored gold and silver thread) of the present invention will be explained based on the drawings.

FIG. 1 is a schematic partial sectional view showing an embodiment of the iridescent gold and silver thread of the present invention. In Figure 1, (1) is a transparent plastic film, on one side of which there is a transparent resin undercoat layer (a1), a first antimony oxide thin film layer (3) with non-uniform thickness, and a transparent resin intermediate layer. (4), a second antimony oxide thin film layer (5) and a transparent resin overcoat layer (6) are provided in this order.Then, a laminate having the same structure and an adhesive layer (7) are sandwiched between the plastic The iris-colored gold and silver threads of the present invention are bonded together with the film on the outside.

In the present invention, the transparent resin topcoat layer (6) can be omitted, but the presence of the topcoat layer is superior in georgette processing resistance, scouring resistance, washing resistance, etc.

In the present invention, each laminate has two antimony oxide layers sandwiching a transparent resin intermediate layer, and at least the first antimony oxide layer has a thin film layer (3) with a non-uniform thickness. Because of this, the iris colors are rich, strong, and have excellent luster.

In addition, antimony oxide was selected from among many iris compounds, the structure of the laminate of the present invention is that the outside is a plastic film as shown in FIG. 1, and the first antimony oxide thin film layer (3 ) is provided on the plastic film (1) via the resin undercoat layer (2), and the adhesion between the thin film layer (3) and the plastic film (1) is excellent. The iris color and luster do not deteriorate even under such harsh conditions. Of course, it also has good resistance to processing treatments such as bleaching, dyeing, and scouring, as well as good washing resistance, and the deterioration or loss of iris color due to these treatments is prevented.

The transparent plastic film (1) used in the present invention is not particularly limited, and includes films conventionally used for applications such as gold and silver thread, such as polyester, polyamide, polyamideimide, polyethylene, polypropylene, cellulose acetate, polycarbonate, and polychloride. Resin films such as vinyl and fluororesin are used as appropriate. The thickness of transparent plastic film is usually 4 to 100 mm.
It is appropriately selected from the range of J, more preferably from the range of 6 to 5oAIm. The mechanical properties of the transparent plastic film determine the weavability and texture by influencing the mechanical properties of the iridescent gold and silver thread, which can be obtained almost as is, so they are appropriately selected and used in consideration of these factors.

Additives such as antistatic agents, ultraviolet absorbers, antioxidants, and colorants may be added to the plastic film as necessary.

The thickness of the transparent resin undercoat layer (2) in the present invention is usually 0.0
It is a uniform one selected from a range of 1 to 5 ρ, more preferably a range of 0.02 to 3 ρ. The thickness of the transparent resin undercoat layer is 0.01. If it is less than is, the effect is significantly inferior, and 5-
Exceeding this is not preferable since the overall material becomes stiff and lacks weavability and texture.

As the resin for forming the transparent resin undercoat layer (2), various resins such as thermoplastic resins, thermosetting resins, electron beam curable resins, and ultraviolet curable resins can be used.
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. Curable resins are particularly preferred.

The transparent resin undercoat layer [2] is formed by applying an organic solvent solution, an aqueous solution, etc. of the resin to, for example, a gravure coating method,
This is done by applying it to a uniform thickness using a normal coating method such as a spray coating method, and drying (curing in the case of thermosetting resin, electron beam curable resin, ultraviolet curable resin, etc.).

The antimony oxide thin film layer of the present invention includes 5b20x, 5b2
In addition to D < , 5b20 s, the formula 5bOx (X −1
~2.5 real numbers) is used.

In the present invention, the first antimony oxide thin film layer (3) having a non-uniform thickness is usually made to have a non-uniform thickness within a range of 5 to 100 r+g, more preferably within a range of 20 to 100 gOn. If the thickness of the thin film layer is less than 5 ns, the iris gloss cannot be changed, which is not preferable. On the other hand, if it exceeds 100n1, the iris gloss will be rather poor, which is not preferable. The degree of non-uniformity in the thickness of the thin film layer (difference between thick and thin parts of the thin film layer (hereinafter referred to as non-uniformity) is preferably about 20 to 8 off1. If the degree of non-uniformity is less than 20r1-, the color development will be monotonous and it will be difficult to change the rich iris color, while if it exceeds 80nm, the strength of the iris color will decrease, cracks will easily occur, and the resistance to georgette processing will also decrease. Undesirable. 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 204, but within this range. It is not limited. Note that the period may or may not be constant. The iris pattern is usually a striped pattern, but is not limited to this.

The antimony oxide thin film layer (3) may be formed by using an evaporation source material using 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.

In order to make the thickness of the thin film layer non-uniform, when using a continuous or semi-continuous evaporation system, for example, in the vacuum chamber of the evaporation system, the evaporation source and the object to be deposited (resin undercoat layer) are continuously moved. (Plastic film (1) with 2
), and a mask having appropriate through holes (usually slit-like holes) is interposed between the evaporated material and the evaporated material, and the vapor deposition is performed while the mask is reciprocated in a direction perpendicular to the flight direction of the evaporated material. .

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 antimony oxide thin film layer (3) is a value measured using a crystal oscillator thickness monitor.

The thickness of the transparent resin intermediate layer (4) in the present invention is usually 0.
It is selected from the range of 0.01 to 5, more preferably 0.02 to 3. The thickness of the transparent resin intermediate layer is 0.01. c.
If it is less than 5J, the resistance to the above-mentioned treatments will not be sufficient (unpreferable).On the other hand, if it exceeds 5J, it will become rigid as a whole and lack weavability and texture, which is not preferable. It may be uniform or non-uniform, but if it is non-uniform, the iris will have a richer color.If it is non-uniform, the degree of non-uniformity of the thickness should be about 0.1 to 1-1. If the degree of non-uniformity is less than 0, i J1, the color development will be monotonous and a rich iris color will be obtained.If the degree of non-uniformity is less than 1, the color development will become pale, which is not preferable. The period of sa (hereinafter,
The non-uniform period) corresponds to the density of the iris pattern, and is usually preferably about 0.5 to 201, but is not limited to this range. 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.

As the resin for forming the transparent resin intermediate layer, various resins such as thermoplastic resins, thermosetting resins, electron beam curable resins, and ultraviolet curable resins can be used. For example, acrylic resins, styrene resins, etc. 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, aminoalkyd resin, rosin-modified maleic acid resin, and the like are preferably used alone or in mixtures. In particular, curable resins are preferably used.

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

In the present invention, the second antimony oxide thin film layer has a thickness of 20 to 80 nm, similar to the first antimony oxide thin film layer. The thickness of the second antimony oxide thin film layer may be non-uniform or uniform. In the case of non-uniformity, the thickness, degree of non-uniformity, period of non-uniformity, etc. are similar to those of the first ammothine oxide layer, but do not necessarily have to be exactly the same.

Furthermore, a transparent resin overcoat layer of uniform thickness can be provided on the second antimony oxide thin film layer, if necessary. The material, coating method, and thickness of the transparent resin top coat layer can be the same as those of the transparent resin intermediate layer.

The transparent resin top coat layer, transparent resin intermediate layer and transparent resin undercoat layer may be colored with dyes and/or pigments as long as the transparency is not impaired, and if necessary, antioxidants, Antistatic agents, ultraviolet absorbers, etc. can also be added.

In the present invention, two of the laminates obtained as described above are laminated using an adhesive with the plastic film on the outside to form a two-bly structure. In this case, two identical laminates may be used, or two laminates with different thicknesses, non-uniformities, etc. may be used. By adopting such a configuration, it becomes possible to withstand not only scouring treatment but also di-N-zet processing.

As the adhesive, urethane resin type, epoxy resin type,
Adhesives such as polyester resin, acrylic resin, and synthetic rubber are used as appropriate.

The iris-colored gold and silver thread of the present invention can be obtained by slitting the above-mentioned laminate having a two-fly structure into an appropriate width, for example, a width of 0.15 to 2M.

The iridescent gold and silver threads of the present invention are particularly suitable for georgette processing because they can withstand the harsh conditions described above.
