[0002]

2. Description of the Related Art In various fields such as furniture, building materials, and weak electricity, it is one of designs to make matte surfaces of products in these fields. Means for making the product surface matte include, for example, a method of directly applying a matte paint to the product, a method of transferring the transfer foil to the product using a transfer foil having a matte resin layer formed in advance, and a matte resin. There are various methods such as a transfer method of transferring a layer, a method of using a decorative material which has been matted on the surface of a substrate by using various means, and attaching the decorative material to the product surface.

[0003] By the way, instead of providing a matte surface on the entire surface, only a desired portion is made to have a matte state, or a part of the matte surface having a partially different matte state is formed. May be required. Conventionally, when a partially matte state is formed as described above, for example, 1) in the case of a transfer foil, an ink layer having an internal cohesion force smaller than the adhesion force of the base film / ink and the ink / peeling portion on the base film. A method of forming a transfer foil partially provided with a transfer foil, performing transfer using the transfer foil, delaminating the ink layer to make the portion matte, 2) using a transfer foil having a normal gloss After performing the transfer, masking is applied to a portion that is not desired to be matted, and then a transfer foil provided with a matting layer on the entire surface is used. Thereafter, the masking is removed and only a desired portion is matted. Step transfer method, 3) Pattern layer and mat layer of matting ink containing matting agent directly on base film,
Method of partially forming an adhesive layer and transferring the pattern layer 4) Using a release ink containing a matting agent on the surface of the base material film, partially forming a matte portion by printing, and curing and adhering. A method of using a transfer foil in which a release layer, a pattern layer, an adhesive layer, and the like are sequentially laminated after forming a release layer; 5) In the case of a molded article such as an injection molded article, There is known a method in which a grain is provided on a portion to be matted and molded, and only the grain is matted.

[0004]

The characteristics required as a matte surface are to obtain a soft touch like suede and to obtain a super-matte state with a high matte degree. It is demanded that the matte state described above can be easily provided without a complicated process.

[0005] However, when the transfer foils 1) and 3) are used, a matte state is small, and a soft touch with a soft touch cannot be obtained. When the transfer foil of 4) is used, it is possible to obtain a considerably matte state as compared with 1), but there is also a disadvantage that a soft suede-like one having a soft touch can not be obtained. The method () has a problem that the steps are complicated and workability is poor. In the case of 5) in which a transfer foil is not used, there is a problem that a suede-like soft touch cannot be obtained although the matte state is excellent. In the case of 6), it takes time to dry the ink or paint, and when the product is made of a material which is weak to the solvent, the ink or paint may be deteriorated or deteriorated by the solvent in the ink or paint. This problem is particularly serious in the case of ink containing a matting agent such as bead pigment, since a slow drying solvent is often used.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and is intended to partially form a matte state or to form a part having a different matte when the matte portion or the matte is different. Matte transfer with excellent design that the part is soft like suede, super matte, easy to manufacture transfer foil, and easy to apply matte using transfer foil An object of the present invention is to provide a foil, and to provide a decorative material which is provided with a partially matte state or has a matte part having a different gloss, and is easy to manufacture. .

Embodiments of the present invention will be described below in detail with reference to the drawings. Drawings show an example of the present invention, Drawing 1 shows an example of the present invention transfer foil, (a) is a longitudinal section, and (b) is a longitudinal section after transferring to other base materials. As shown in FIG. 1, the matte transfer foil 1 of the present invention has a matte fine unevenness 2 composed of a fine unevenness coating layer having a specific surface shape formed using, for example, a releasing binder resin to which a matting agent has been added. Using a shaping film 3 partially provided on a film 4, a matting resin layer 5 and an adhesive layer 6 are sequentially formed on the surface of the shaping film 3 on which the matte fine irregularities 2 are formed. They are stacked.

The base film 4 used for the above-mentioned shaped film 3 is not particularly limited as long as it is used as a usual base material for a shaped film. The thickness of the base film 4 is usually about 12 to 100 μm. Examples of the material of the base film 4 include polyolefin such as polyethylene and polypropylene, polyamide, acryl, polycarbonate, polyarylate, polyvinyl chloride, polyethylene terephthalate, polyester such as polybutylene terephthalate, polystyrene, polyvinyl fluoride, polytetrachloroethylene, and Teflon. A film made of a fluororesin such as polyvinylidene fluoride, polyvinyl alcohol, polyetheretherketone, polyimide, cellophane, or the like, alone, or by appropriately bonding those films together, or directly applying the resin to form a laminated film Or a composite with aluminum foil, paper, or the like. Among them, a polyester film is most preferable.

FIG. 5 shows matte fine irregularities 2 of the shaping film 3.
FIG. As the uneven shape of matte fine unevenness,
Depending on the application and the desired product surface gloss, any one may be selected. In order to reproduce suede-like matting well, in particular, as shown in FIG. A matting agent having a shape or a sphere-like shape is preferably composed of a fine uneven coating layer formed by coating so that the center of gravity X of the matting agent has a surface state protruding from the average level surface H of the binder component coating film 8.

The surface of the above-mentioned fine uneven coating layer has a surface gloss value (60 ° incidence) of 0.1 to 10% and a surface roughness of 0.5 to 40 μm. The surface gloss value (60 ° incidence) is measured by a specular gloss measurement method according to JIS Z8741. The surface roughness is measured from the position H where no matting agent is present to the matting agent of the coating film. It is represented by the distance from the existing portion to the maximum protruding portion Y.

The matting agent added to the fine uneven coating layer is
It is added to give a matte state, and its shape is generally spherical, and in addition to this, it can be used as an ellipse, eggplant type, cardioite similar to a spherical shape with a smooth surface A shape such as a rotating body rotated about a shaft is used. Examples of the material of such a matting agent include fine particles and bead pigments, and these can be used alone or in combination.

Examples of the material of the fine particles include silica, alumina, calcium carbonate, precipitated barium sulfate, clay, shirasu balloon, benzoquanamine, and talc. The particle size of the fine particles is about 0.8 to 30 μm, preferably about 1.0 to 30 μm. Further, the amount of the fine particles added to the binder resin can be appropriately determined according to the surface gloss value of the fine uneven coating layer.

As the bead pigment, for example, Fe ₂ O
₃ , the surface of fine powder of ordinary pigments such as TiO ₂ , CaCO ₃ and quinacridone is coated with elastic resin such as polyurethane, acrylic, epoxy, polyester, nylon, fluororesin, vinyl chloride-vinyl acetate copolymer, etc. Is used. The bead pigment having a particle size of 2 to 30 μm is more preferable because it can exhibit a suede-like texture and improves the coating property of the adhesive layer 6 and the adhesion to the substrate.

The surface gloss value and the surface roughness of the matting agent added to the coating film are, in the case of fine particles, in the range of 0.1 to 10% in surface gloss value and 0.5 to 30 μm in surface roughness. Preferably, in the case of a bead pigment, the surface gloss value is 0.1.
The surface roughness is preferably from 1 to 6% and the surface roughness is from 1 to 40 µm.

The releasable binder resin which forms the fine uneven coating layer while holding the matting agent has good adhesion to the base film 4 and, after transfer, the shaped film 3
Any material may be used as long as it has good mold releasability from the matte resin layer 5 when peeling off. As the material of the release binder resin, for example, a thermoplastic resin or an ionizing radiation curable resin can be used. As the ionizing radiation curable resin, polyester acrylate, urethane acrylate, 2-hydroxylethyl acrylate, neopentyl glycol di- Acrylates and the like are preferred. In addition, as the ionizing radiation, an ultraviolet ray or an electron beam is often used.

In order to form the fine uneven coating layer, a known gravure,
It can be provided by any printing method such as silk screen. Further, the pattern of the fine uneven coating layer may be appropriately determined according to a desired pattern to be matted, and, for example, a lattice shape, characters (such as a company logo) and the like can be arbitrarily provided.

(Transfer object) side, the matte resin layer 5
Is usually formed as the surface of the transfer object. Therefore, a portion corresponding to the pattern of the above-mentioned matte fine irregularities 2 becomes the concave portion 10, and the inside of the concave portion 10 is formed in a matte shape (see FIG. 1B).

FIG. 6 is an enlarged view of the matting resin layer 5 after the shaping film is peeled off. As shown in FIG. 6, since the matte resin layer 5 becomes the other substrate surface after the transfer, when the matte fine irregularities are formed as the above-mentioned fine unevenness coating layer, the shaping film 3 is formed. After peeling, the surface is formed so as to be a concave portion 18 having an inner expanding shape.

Next, the matting resin layer 5 provided on the surface of the shaping film 4 may be formed of a resin having desired physical properties. A resin other than a thermosetting resin is preferable because a distortion is easily generated in the base material due to high heat, and a thermoplastic resin, an ionizing radiation curable resin, or the like is used.

Specific examples of the material of the matting resin layer 5 include acrylic, chelate-curable acrylic, polyester urethane, and two-component curable epoxy-curable acrylic, acrylic urethane, urethane elastomer, and ionizing radiation-curable resin. Polyester acrylate,
Examples thereof include urethane acrylate, 2-hydroxyethyl acrylate, and neopentyl glycol diacrylate. Among them, acrylic urethane and urethane elastomer are preferable because a resin layer having excellent scratch resistance can be obtained.

The matting resin layer 5 contains at least a matting agent.
It is composed of the releasable binder resin added. mat
The agent enhances the matting effect of the matting resin layer. Matte resin layer
5 can also be arbitrarily colored. The above Ma
Fine particles, bead pigments and the like added to the above-mentioned matte fine irregularities may be used as the soaking agent . In particular, when a suede ink in which a bead pigment is added to a vehicle is used, a suede-like texture can be exhibited, and the coating properties of the adhesive layer and the adhesion to the substrate are improved.

In order to form the matting resin layer 5, a paint or a suede ink in which pigments or fine particles are dispersed in the above resin is applied to the surface of the matting fine irregularities 2 of the shaping film 3 by gravure coating or roll coating. The coating is performed by a coating method such as the above or a printing method such as the screen printing, and the resin is dried or cured by heating or irradiation of ionizing radiation to form the resin. The thickness of the matting resin layer 5 is 25 to 35 μm (10 to 30
g / m ² ) is preferred. In addition, this mat resin layer,
It is sufficient that the pattern is at least larger than the pattern of fine irregularities (that is, it can be shaped), and it may be formed in a partial pattern other than the entire surface.

The adhesive layer 6 is for ensuring good adhesion between the matting resin layer and the transfer-receiving body, and may be appropriately determined from known adhesives depending on the material of the other base material.
Generally, an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a rubber-based resin, a thermoplastic urethane resin or the like, or a mixture of the above resins is used. 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.

When a urethane resin is used as the resin of the matting resin layer and the resin layer is in direct contact with the adhesive layer, a vinyl chloride-vinyl acetate resin copolymer is used as the adhesive resin. When the content is 20% by weight, the matte resin layer 5
This is preferable because adhesion between the resin and the adhesive resin becomes better.
The thickness of the adhesive layer 6 may be any thickness as long as it can sufficiently cover the unevenness of the matting resin layer and can sufficiently secure the adhesive force to the transfer target.

If the matting resin layer itself has adhesiveness, the adhesive may be omitted. However, in this case, the adhesive of the matte resin layer, which also functions as the adhesive layer, is avoided from the viewpoint of releasability from the molding film at the time of transfer, stickiness of the surface after transfer, and prevention of contamination.

FIG. 1B is a cross-sectional view showing a case where transfer is performed using the matte transfer foil of the present invention. As shown in the figure, the matte transfer foil 1 of the present invention is overlaid so that the adhesive layer 6 is in contact with the other base material 13 and, if necessary, subjected to pressure or heating, etc. By peeling off, the transfer layer 9 is easily transferred to the other base material 13 to provide a surface having a matte portion partially, thereby obtaining the decorative material of the present invention. The above-mentioned other base material 13 may be any one which is usually used as a base material of a decorative material, for example, a woody base material such as MDF and particle board, a flat plate such as a metal plate such as an iron plate, a vinyl chloride coated steel plate and an aluminum plate. Or three-dimensional molded articles, paper, woven or nonwoven fabric, resin sheets, sheets such as metal foils, ceramic sheets, thermoplastic resin sheets, thermosetting resin sheets and other plate-like bodies, and composites of the above materials.
