As described above, a matte transfer foil using a bead pigment can provide an excellent matte design having a tactile feel like a suede, however, since a bead pigment is used in a single color. In addition, the three-dimensional appearance and color depth were poor. Therefore, in order to give a three-dimensional effect and color depth, an attempt was made to use a mixture of bead pigments of two or more colors, but simply mixing differently colored bead pigments would result in a three-dimensional effect and color depth. It turned out that it did not improve much.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and provides a matte transfer foil capable of providing a design having a matte effect such as suede and a more excellent three-dimensional effect and color depth. The purpose is to do.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. The drawings show an embodiment of the present invention, and FIG. 1 shows an example of the transfer foil of the present invention. As shown in FIG. 1, the matte transfer foil 1 of the present invention is a matte transfer foil comprising a base film 2 and a transfer layer 5 having a matte resin layer 4 containing bead pigments 3 laminated thereon. The layer 4 contains at least two colored bead pigments 31 and 32 having different particle sizes. Further, in this embodiment, the adhesive layer 6 is provided on the matting resin layer 4, and the matting resin layer 4 and the adhesive layer 6 are formed as the transfer layer 5.

The bead pigment 3 only needs to be different in color from at least two types of bead pigments having at least two bead pigments, that is, bead pigments 31 having a large particle diameter and bead pigments 32 having a small particle diameter. In the present invention, it is important that the matting resin layer 4 contains bead pigments of two colors having different particle diameters. Thus, not only the bead pigments of two colors but also the bead pigments of different colors are contained. By varying the particle size of the above, a matte resin layer 4 having a matte surface such as suede can be provided with a design having a more three-dimensional appearance and color depth. The particle size, color, etc. of the two-colored bead pigments 3 having different particle diameters are not particularly limited, but those having an average particle size of about 5 to 100 μm are usually used, and bead pigments having a large particle diameter are preferably used. It is preferable to use a pigment having an average particle diameter of 45 to 100 μm, particularly preferably 50 to 80 μm, and to use a bead pigment having a small particle diameter in combination with an average particle diameter of 5 to 45 μm, particularly preferably 10 to 40 μm. desirable.

FIG. 3 is a sectional view showing another embodiment of the mat resin layer. As shown in FIG. 3, the matte transfer foil of the present invention is obtained by changing the bead pigment 3 of the matte resin layer 4 to red (3A) and yellow (3A).
b) and three different colors of black (3c). In this case, the color is different between the bead pigment 3A having a large particle diameter and the bead pigments 3b and 3c having a small particle diameter. By such a combination, the matte resin layer 4 shown in FIG.
(Red): Bead pigment 3b (yellow) or Bead pigment 3A
(Red): A three-dimensional effect is obtained due to the relationship of the bead pigment 3c (black). However, for example, bead pigments 3A and 3b of different particle sizes
(Or the colors of 3A and 3c) are the same, such as red and red, and black and black, a stereoscopic effect cannot be obtained.

Each bead pigment 3 in the matte resin layer 4
The content, mixing ratio, and the like of are not particularly limited, but the mixing ratio of the two types of bead pigments is set such that the content of the bead pigment having a large particle size is 2 to 15% by weight of the content of the bead pigment having a small particle size.
It is preferable that When the content of the large particle bead pigment is less than 2% by weight, the color effect cannot be obtained because the absolute addition amount of the large bead pigment is small and the color effect cannot be obtained, and the large particle bead pigment increases. The effect is excellent in three-dimensional effect and color depth, but 15% by weight.
If it exceeds 300, the coatability and smoothness when formed on the surface of the base film tend to decrease, and the adhesion to the base film and the adhesive layer tends to decrease.

The total amount of the above-mentioned bead pigments to be added may be appropriately determined according to the degree of the matting design of the matting resin layer 4, the surface properties of the binder resin used for the resin layer 4, and the cutting properties of the foil. However, it is preferably 20 to 50 parts by weight based on 100 parts by weight of the binder resin.

The above-mentioned bead pigment to be added to the matting resin layer 4 is prepared by, for example, applying a fine powder surface of a usual pigment such as Fe ₂ O ₃ , TiO ₂ , CaCO ₃ , quinacridone to polyurethane, acrylic, epoxy, polyester or nylon. , Fluororesin,
An elastic resin such as a vinyl chloride-vinyl acetate copolymer, or a resin formed by adding a plasticizer, a stabilizer, a surfactant, or the like, if necessary, to form a granular resin is used.

As the material of the binder resin forming the matting resin layer 4, a thermoplastic resin, a room temperature curing resin, an ionizing radiation curing resin, or the like is used. Specifically, for example, acrylic, chelate-curable acrylic, polyester urethane, and two-component curable resins include epoxy-curable acrylic, acrylic urethane, urethane elastomer, and the like, and ionizing radiation-curable resins include polyester acrylate and urethane. Acrylate, 2-hydroxyethyl acrylate, neopentyl glycol diacrylate and the like can be mentioned. Among them, acrylic urethane and urethane elastomer are preferable because a resin layer having excellent scratch resistance can be obtained.

In order to form the matting resin layer 4, a coating or suede ink in which the above-mentioned bead pigment is dispersed in the above-mentioned binder resin is applied to the surface of the base film by gravure coating.
It is formed by coating by a coating method such as roll coating or a printing method such as screen printing, and drying or curing the resin by heating or irradiation with ionizing radiation. The thickness of the matting resin layer 4 is not particularly limited, but is preferably about 25 to 35 μm (applied amount of 10 to 30 g / m ² ) from the viewpoint of, for example, breakage of the transfer foil.

The substrate film 2 used in the matte transfer foil 1 of the present invention is not particularly limited as long as it has a releasability from the transfer layer 5 including the matte resin layer 4. The surface shape can be arbitrarily used such as matting and gloss. Usually, in order to obtain a larger matte state, it is preferable to use a so-called shaped film in which fine irregularities 8 are formed on the surface of the base film 1 as shown in FIG. The fine unevenness 8 is formed as an uneven coating layer made of a resin layer containing a matting agent or the like, a material obtained by kneading a matting agent or the like in a base film itself, or a method in which a heating emboss is formed on the surface of the base film. It can be formed into various glossy states by means such as sandblasting and chemical etching.

Although not particularly shown, the base film 2 may be formed by separately forming a release layer on the surface to impart releasability. This release layer contains a component that enables the matting resin layer 4 to be peeled off from the base film 2 during transfer, and specifically includes a suitable vehicle (the same as that used for a normal ink composition or the like). ) It is formed solely or, if necessary, further added with a releasing material such as wax or silicone.

The material of the base film 2 may be any material used as a normal transfer foil base material. Examples of the material include polyolefin such as polyethylene and polypropylene, polyamide, acryl, polycarbonate, polyarylate, polyvinyl chloride, and the like. Polyethylene terephthalate, polyester such as polybutylene terephthalate, polystyrene, polyvinyl fluoride, polytetrachloroethylene, Teflon, fluororesin such as polyvinylidene fluoride, polyvinyl alcohol, polyetheretherketone, polyimide, cellophane, etc. film alone or The films are laminated as appropriate or the resin is applied directly to form a laminated film,
Or, a composite with aluminum foil, paper, or the like can be given. Among them, a polyester film is most preferable. The thickness of the base film 2 is usually about 12 to 100 μm.

The adhesive layer 6 is for ensuring good adhesion between the matting resin layer 4 and the object to be transferred, and may be appropriately determined from known adhesives according to the material of the object to be transferred. .
As the adhesive, an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a rubber resin, a thermoplastic urethane resin, or the like, or a mixture of the above resins is generally used. In particular, when a urethane-based resin is used as the binder resin of the matting resin layer, it is preferable to add about 10 to 20% by weight of a vinyl chloride-vinyl acetate copolymer to the adhesive layer.

The form of the adhesive may be any of a heat-sensitive adhesive, a pressure-sensitive adhesive (adhesive), a solvent-activated adhesive, and an adhesive method using an electron beam, ultraviolet light or the like. If the matting resin layer 4 itself has adhesiveness, the adhesive layer 6 may be omitted. However, in this case, the resin of the matting resin layer 4 also serving as the adhesive layer 6 has a releasability from the base film 2 during transfer,
From the viewpoint of preventing stickiness and contamination of the surface after transfer, it is preferable to avoid an adhesive.

In the matte transfer foil 1 of the present invention, a release layer, a picture layer, a concealing layer and the like can be formed at any positions as the transfer layer 5, though not particularly shown.

The above-mentioned peeling layer facilitates the peeling of the base film, and after the peeling of the base film, transfers to the object to be transferred to become the outermost surface of the transfer layer, thereby protecting the surface of the matting resin layer 4 or the like. For the purpose of adjusting the gloss of the surface. The material of the release layer may be any of those commonly used for transfer foils.Specifically, polymethyl methacrylate, polybutyl methacrylate, polyethyl methacrylate, vinyl chloride-vinyl acetate copolymer, urethane, epoxy resin,
Resins such as cellulose alone or a mixed resin thereof may be used. The release layer may be added with a wax, a matting material, or the like, if necessary, to the resin. These resins are applied by a coating method such as gravure coating or roll coating or a printing method such as screen printing or gravure printing to form a release layer.

The pattern layer is provided for improving the decorativeness of the transfer foil, and is formed using a normal printing ink, for example, an ink using a resin similar to the resin forming the release layer as a vehicle. A desired pattern is printed and formed at an arbitrary position such as between the matting resin layer 4 and the adhesive layer 5 or between the matting resin layer 4 and the base film. Printing methods include gravure, silk screen, and offset.
In addition to the pattern layer, a pattern layer, a pattern layer, a pattern layer, a metal layer, a partial metal layer, etc. may be used alone or in combination with two layers. It can be formed from the above.

FIG. 2 is an explanatory view showing a state in which transfer is performed using the matte transfer foil of the present invention. The present matte transfer foil 1
As shown in FIG. 2, the transfer layer is superposed such that the adhesive layer 6 is in contact with the object to be transferred 7, and after applying pressure or heating as necessary, the base film 2 is peeled off. 5 can be easily transferred to the surface of the transfer receiving member 7 to provide a matte surface. Various materials can be used as the transfer object 7, for example, a woody base material such as MDF and particle board, a flat plate or a three-dimensional molded body such as a metal plate such as an iron plate, a vinyl chloride coated steel plate and an aluminum plate, paper, and a woven fabric. Sheets such as cloth or nonwoven fabric, resin sheets, metal foils, etc., plate-like bodies such as ceramic plates, thermoplastic resin plates, and thermosetting resin plates, and composites of the above materials are also included.
