Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suede-like transfer foil used for imparting a suede-like outstanding matte appearance to an object to be transferred. Applications include surface makeup in various fields such as furniture, building materials, and light electrical appliances.

[0002]

2. Description of the Related Art Conventionally, in various fields such as furniture, building materials, and light electrical appliances, the product surface has a soft matte surface appearance,
In order to impart a so-called suede-like surface appearance, for example, a method is known in which a suede-like paint containing a bead pigment in a binder resin is directly applied to the product surface.

In addition to the above method, as a means for imparting a suede-like surface appearance to a product surface by using a transfer foil, a release binder resin containing fine particles such as bead pigments in a film base is used. On the film for fine unevenness shaping film provided with a release layer consisting of, a suede-like resin layer to be shaped,
Another known method is to transfer the shaped suede resin layer and the adhesive layer of the transfer foil having the adhesive layer formed thereon to the surface of the product.

[0004]

In a transfer foil for imparting a suede-like appearance to a product, when a conventional transfer foil is coated with an adhesive on the suede-like resin layer, it is formed in a porous suede-like resin layer. The adhesive penetrated and had a bad effect on color and foil breakage, and because the surface of the suede-like resin layer had irregularities, and the applied adhesive layer was absorbed, the suede-like resin layer became the transfer target. On the other hand, in order to improve the adhesion, it is necessary to increase the amount of adhesive applied. If the coating amount of the adhesive is increased, the adhesion is improved, but the foil breakage is deteriorated and burrs are generated. The present invention has been made to solve the above problems, and a sealing resin layer containing a pigment such as a bead pigment or an extender pigment having a thickness of 0.5 to 10 μm is provided between a suede resin layer and an adhesive layer. As a result, the unevenness of the suede pigment having a large particle diameter was smoothed, and the absorbability of the adhesive was reduced to reduce the amount of the adhesive applied, thereby improving the adhesiveness and the foil cutting property.

[0005]

That is, the suede-like transfer foil of the present invention is a transfer formed by sequentially providing a transfer layer comprising at least a suede-like resin layer, a sealing resin layer and an adhesive layer on the surface of a releasable shaping film. It is a foil, and the surface of the shaped film is formed as a matte rough surface having a surface gloss value (JIS-Z-8741 75 ° incidence) of 20 or less, and the suede-like resin layer is at least the most frequent particles. Diameter 10-40μ
m is a resin containing a bead pigment, and the sealing resin layer is made of a resin containing a pigment having a particle diameter of at least 0.5 to 10 μm.

[0006]

In the transfer foil having the above-described structure, the sealing resin layer containing a pigment such as an extender pigment having a thickness of 0.5 to 10 μm is provided between the suede resin layer and the adhesive layer to prevent unevenness of the suede resin layer. The filling amount of the adhesive can be reduced by filling and smoothing the adhesive, and reducing the amount of the adhesive applied to the suede-like resin layer to effectively reduce the amount of the adhesive applied. As a result, the adhesiveness was improved and the foil cutting property was improved.

Embodiments of the present invention will be described below with reference to the drawings.

(Example 1) A suede-like transfer foil 1 of the present invention comprises a shaped film 2 including a release layer 8 as shown in FIG.
A suede-like resin layer 3 for imparting a suede-like surface 3a to the transferred material is provided on the surface of the above, and a sealing resin layer 4 and an adhesive layer 5 are sequentially provided on the resin layer 3.

The shaped film 2 uses a matte film whose glossiness is adjusted by kneading a matte material, sandblasting, chemical etching or the like in order to make the surface of the film substrate 6 matte. In order to improve the releasability between the shaping film 2 and the suede tone resin layer 3 at the time of transfer, a release layer 8 may be separately provided on the surface of the film substrate 6, and the releasable layer 8 is the suede tone resin. A component (appropriate vehicle) that makes the layer 3 releasable, a releasable binder resin made by further adding a releasable substance such as wax silicon, if necessary, and a suede-like resin layer after peeling the shaped film It is composed of extender pigment 7 dispersed in the resin in order to form fine irregularities that form a matte rough surface. In addition, especially the surface of the suede-like resin layer 3 is JIS
In order to obtain a matte surface with a gloss value of -Z-8741 of 75 ° incidence method of 5 or less, it is preferable to form an inflated concave portion on the surface of the suede resin layer as shown in FIG. For that purpose, a bead pigment is used as a pigment dispersed in the release layer 8.

The material of the base material 6 of the shaped film is, for example, polyolefin such as polyethylene or polypropylene, polyester such as polyethylene terephthalate or polybutylene terephthalate, polyvinyl fluoride, polytetrafluoroethylene (Teflon) or polyvinylidene fluoride. , Such as fluororesin, polyvinyl chloride, polyether ether ketone, polyimide, cellophane, etc. alone, or by appropriately laminating these films, or by directly coating the resin into a laminated film, Alternatively, a composite with aluminum foil or the like may be used, and among them, a polyester film is most preferable.

Glass beads, shirasu balloons and the like can be used as the bead pigment 7 used in the release layer 8. In particular, from the viewpoint of the abrasion resistance, flexibility and suede feel of the suede-like resin layer, Resin beads are desirable, for example
_{Fe 2 0 3, TiO 2,} CaCO 3, the powder surface of the conventional pigments of quinacridone, polyurethane, acrylic,
Those coated with an elastic resin such as epoxy, polyester, nylon, fluororesin, vinyl chloride vinyl acetate copolymer, etc. are used. The most frequent particle size of the pigment is 5
-80 μm is suitable.

The suede tone resin layer 3 is preferably formed by the method disclosed in, for example, Japanese Patent Laid-Open Nos. 4-125198 and 2-26800. That is, the surface of the shaped film 2 has a particle size distribution range of 5 to 5.
By forming the suede-like resin layer 3 containing at least the bead pigment 9 having a particle size of 80 μm and the most frequent particle diameter of 10 to 40 μm, the suede-like resin layer 3 on the shape-imparting film side surface after peeling off the shape-imparting film 2 is suede-like The surface 3a can be formed.

The resin material used for the suede-like resin layer 3 may be any material other than a thermosetting resin, and a thermoplastic resin, an electron beam curable resin or the like can be used. When the suede resin layer 3 is made of thermosetting resin,
There is a problem that the temperature of thermosetting is high and the base material is likely to be distorted by high heat during curing. Examples of resin materials include acrylic, chelate-curable acrylic, vinyl chloride, vinyl acetate copolymer, rubber, etc., and two-component curable types include epoxy-curable acrylic, acrylic urethane, polyester urethane, urethane elastomer, electron beam curable. Examples of the resin include polyester acrylate, urethane acrylate, 2-hydroxyethyl acrylate, neopentyl glycol diacrylate and the like. Among them, acrylic urethane, urethane elastomer and the like are preferable because a resin layer excellent in scratch resistance can be obtained. Further, the suede-like resin layer 3 may be optionally colored in order to enhance the matte effect.

Bead pigment 9 used for suede-like resin layer
The same as those used for the release layer can be used, but the most frequent particle size when used for the suede-like resin layer is 10 to 40 μm in order to express the suede-like matteness and feel of the surface. Those in the range of are suitable. In particular, if the most frequent particle size is 10 to 15 μm and it is combined with a wood grain pattern, it is possible to approximate the luster appearance of the surface of the wood grain board, and the addition amount of these bead pigments is 15 to 100 wt%. In forming the suede-like resin layer 3, after applying the suede ink in which the bead pigment 9 is dispersed in the vehicle 10 or the like to the surface of the shaping film 2 by a coating method such as gravure coating or a printing method such as screen printing, if necessary. The resin material can be formed by heating or irradiating ionizing radiation to dry or cure the resin material.

The sealing layer 4 may be one that adheres well to both the suede-like resin layer and the adhesive layer provided on the patterning film, but is generally an acrylic resin, vinyl chloride-
A single substance such as a vinyl acetate copolymer, a rubber-based resin, a thermoplastic urethane resin or a mixture thereof can be used, and can be formed in the same manner as the suede-like resin layer.

The extender pigment 11 used for the filling layer is
Silica, talc, calcium carbonate, magnesium carbonate,
Precipitated barium sulfate or the like is preferable, and the amount of application may be such that the uneven shape of the suede-like resin layer is reduced, and is preferably smooth. For that purpose, it is necessary to make the most frequent particle size smaller than the bead pigment in the suede-like resin layer, specifically, 0.5 to 10 μm is preferable. Further, by adding a bead pigment of small particle size of 0.5 to 10 μm to the sealing layer, the formation of the adhesive layer can be facilitated at the time of manufacturing the transfer foil, and the suede-like resin layer can be transferred smoothly after the transfer. Also, the foil is well cut and burrs do not appear. The bead pigment 12 used in the filling layer 4 is the same as that used in the release layer, and the most frequent particle size is 0.5 to 1
It can be selected and used in the range of 0 μm. Further, at the time of transfer, the transfer layer is not cut along the boundary between the transfer layer and the portion in contact with the transfer target at the peripheral portion of the transfer target.
In order to prevent such foil burrs from occurring, the amount of extender pigment or bead pigment added is 1 to 15% by weight.

The adhesive layer 5 can be formed by using an adhesive appropriately selected depending on the material of the transferred material 12, and is generally an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a rubber resin, a thermoplastic urethane resin. An adhesive such as a single substance or a mixture thereof can be used. If the coating amount of the sealing resin and the adhesive is sufficient, the adhesion will be excellent, but the processing suitability will deteriorate (foil flash will occur). On the contrary, if the coating amount is reduced, the workability is excellent, but the adhesion is poor. There is a conflict between workability and adhesion, and it is necessary to balance them. The coating amount of the sealing resin layer + adhesive is preferably 5 to 30 μm.

When the suede-like transfer foil 1 of the present invention is used for transfer onto a transfer-receiving member, as shown in FIG. 2, the transfer-receiving member 13 is superposed so that the adhesive layer 5 is in contact with it.
By applying pressure, heating, or the like as needed, and then peeling off the shaping film 2, a suede-like surface 3a having excellent adhesion to the surface of the transferred material and less burr can be obtained. Next, the present invention will be described in more detail with reference to specific examples.

(Example 2) A coating mat PET film (manufactured by Kimoto Co., Ltd.) having a surface roughness of 1.0 μm and a surface gloss value of 2.0% (JIS-Z-8741 incident at 75 °) and a thickness of 25 μm. Suede ink (manufactured by Showa Ink Manufacturing Co., Ltd.) in which 40 wt% of the bead pigment having the most frequent particle diameter of 20 μm is dispersed on the surface of the mold mat 1017-6).

Gravure coater to 0 g / m ^2, and then an adhesive (Showa Ink Mfg. Co., Ltd .: HS-32) is sequentially coated with a comma coat so that the coating amount is 10 g / m ² .
A sealing layer and an adhesive layer were formed to obtain a transfer foil. 3% by weight of silica (the most frequent particle size 5 μm) was added to the resin of the sealing layer. When the obtained transfer foil was transferred to a PS substrate with a slit shape, it had a blush-free, completely matte like suede, a high design with a soft feeling, and excellent adhesion to the transfer substrate. A molded product was obtained.

In order to confirm the effect, the transfer product obtained in Example 2 and the suede-like resin layer were directly coated with an adhesive by comma coating without providing the sealing resin layer of the present invention. The transfer products obtained by coating so that the coating amount was 30 g / m ² were compared, and the results are shown in the table below.
