Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material for exterior and interior materials of a house, furniture, home electric appliances and the like, and more particularly to a transfer method for producing a decorative material having a decorative uneven surface. It is.

[0002]

2. Description of the Related Art Among such decorative materials having an uneven surface, a method of obtaining a decorative material having a large three-dimensional uneven surface decorated is disclosed in, for example, Japanese Patent No. 2844424 and Japanese Patent Application Laid-Open No. 10-236092. A transfer technique by projection of solid particles has been proposed. That is, in these publications, a transfer sheet composed of a support and a transfer layer is placed on the uneven surface of the substrate to be transferred with its transfer layer side facing, and solid particles are sprayed on the support side of the transfer sheet to collide with the transfer sheet. A transfer sheet is disclosed in which the transfer sheet is made to follow the surface irregularities of the transfer-receiving substrate by pressing and contacting the transfer sheet by utilizing the collision pressure of the solid particles.

FIG. 1 shows a specific example of an apparatus used for such a transfer method. In the illustrated apparatus, the substrate to be transferred B
Is first preheated by the heating device 21 while being transported by the substrate transport device 11. Then, the transfer sheet S unwound from the unwinding roll 12 is temporarily pressure-bonded to the transfer base material B by a pressing roller 13 made of an elastic body, and is supplied into the chamber 30 integrally with the transfer base material B. In the chamber 30, solid particles P are projected by a solid particle ejector 32 composed of an impeller and made to collide with the support side of the transfer sheet S. Press against the surface. The solid particles P are supplied from the hopper 31,
The used solid particles P are collected in the lower chamber 33 and reused. When the transfer base material B to which the transfer sheet S is pressed comes out of the chamber 30, cool air is blown from the cooling air blowing nozzle 22 to blow off the solid particles P on the transfer sheet S. The support m of the transfer sheet S is peeled off from the sheet B and wound around the winding roll 15 to obtain a decorative plate D as a transfer product.

[0004]

According to the transfer method described in the prior art, a decorative material having a large three-dimensional uneven surface can be easily obtained. When a small amount of air is caught between the two at the time of pressure bonding, as shown in FIG. 2, after the support m of the transfer sheet S is peeled off, the transfer layer transferred to the base material B via the adhesive layer f is removed. In some cases, a small ink floating U occurred at t. After the transfer sheet S is pressure-bonded to the transfer base material B, the transfer sheet is separated from the transfer base sheet without contacting the transfer base material by the minute air therebetween, so that the support m and the transfer layer t are separated from each other. It occurred at the part where it was still attached. Such ink floating may cause the transfer layer t to be removed together with the support m when the support m is peeled off, or may be easily peeled off by friction or the like even if the transfer layer t remains on the transfer-receiving substrate B once. As a result, the transfer layer lacks, that is, ink is lost.

The present invention has been made in view of the above problems, and an object thereof is to transfer a transfer layer from a transfer sheet to a transfer substrate by projecting solid particles. It is another object of the present invention to provide a transfer method capable of obtaining a decorative material free from ink floating and ink bleeding on a transfer layer transferred to a transfer substrate.

[0006]

In order to achieve the above-mentioned object, a first transfer method according to the present invention comprises a step of forming a support and a transfer layer on an uneven surface side of a transfer-receiving substrate having an uneven surface. The transfer sheet is placed with its transfer layer side facing, solid particles are projected on the support side of the transfer sheet, the transfer sheet is deformed by using the collision pressure, and the transfer layer is transferred to the substrate to be transferred. In this method, the transfer sheet is once pressed against the substrate to be transferred by the impact pressure of the solid particles, the solid particles on the support are removed, and the support is peeled off. The method is characterized in that the transfer step is completed by placing the solid particles on the substrate to be transferred, projecting the solid particles from the support side and pressing again, and then peeling the support.

In order to achieve the same object, a second transfer method according to the present invention provides a transfer sheet comprising a support and a transfer layer on an uneven surface side of a transfer-receiving substrate having an uneven surface. The transfer layer side is placed, the solid particles are projected on the support side of the transfer sheet, the transfer sheet is deformed by using the collision pressure, and the transfer layer is transferred to the transfer substrate and transferred. The method is such that the transfer sheet is once pressed against the substrate to be transferred by the collision pressure of solid particles, the solid particles on the support are removed, the support is peeled off, and the peeled support is transferred again. The method is characterized in that the substrate is placed on a substrate, the solid particles are projected from the support side, pressed again, and then the support is peeled off to complete the transfer step.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION [Substrate to be Transferred] The substrate to be used in the present invention may, of course, have a flat surface to be transferred. The surface is an uneven surface, and in particular, a transferred substrate in which the unevenness is three-dimensional. In the present invention, as will be described later, since the collision pressure of a group of solid particles that behave fluidly is used, the three-dimensional shape of the surface irregularities has essentially no planar direction of the pressure application region. The directionality refers to a direction of a temporal position change of a point on the transfer-receiving substrate to which pressure is applied. Therefore, a transfer substrate having a shape having irregularities in the feed direction of the transfer sheet or the transfer substrate may be used. In other words, it means that the present invention can be applied to two-dimensional unevenness having unevenness only in one direction such as only the feed direction or width direction, and three-dimensional unevenness having unevenness in two directions such as both the feed direction and the width direction. The point that the collision pressure of the solid particle group does not have directionality is that the ejector that ejects the solid particles is placed so that the single-sheet transfer sheet is placed on the substrate to be transferred and pressed into contact one by one. This can be easily understood by considering how the area to which the collision pressure is applied moves by moving or transferring the transfer sheet and the base material to be transferred while fixing the ejector.

The substrate to be transferred is not limited to a flat plate material (having an envelope shape) as a whole, but may be a substrate having two-dimensional irregularities that are convex or concave in an arc shape and are curved in the feeding direction or width direction. Alternatively, the curved surface may have finer three-dimensional surface irregularities. In the present invention, whether to transfer the two-dimensional irregularities having an arc-shaped cross section of the base material to be transferred, for example, in the width direction or in the feed direction is arbitrary in consideration of workability and the like. Can be.

It is also possible to use a substrate to be transferred having an irregular surface having fine irregularities superimposed on large irregularities, or a substrate having a surface to be transferred to the bottom or inner surface of the concave portion of the irregular surface. . The large irregularities and the fine irregularities are, for example, as shown in an enlarged perspective view of a main part of FIG. The large irregularities have a step of 1 to 10 mm, a width of the concave portion of 1 to 10 mm, and a width of the convex portion of 5 mm or more. The fine irregularities have a step and a width. Both are smaller than the large uneven shape, specifically, the step is about 0.1 to 5 mm, the width of the concave portion and the width of the convex portion are 0.1 mm or more, and 1/2 of the width of the convex portion of the large uneven shape. Less than about.

As a specific example of an uneven pattern of a decorative material having a combination of large and small irregularities and fine irregularities and having three-dimensional surface irregularities, for example, there are joints and grooves as large irregularities. It has a two-dimensional array pattern of tiles, bricks, stones, etc., and fine irregularities on the spray painted surface such as stucco, lysine, etc., unevenness of stone surface such as granite cleavage surface and travertine marble board Joints, grooves, as a stone-grained uneven pattern having a large pattern, etc.
It has a siding pattern, shaved wood pattern, and a floating wood grain pattern, and a conduit groove as fine irregularities on it, a raised annual ring,
Wood-grain uneven patterns having a hairline or the like can be given.

Each of the surfaces constituting the concave-convex surface is arbitrary, including only a flat surface, only a curved surface, or a combination of a flat surface and a curved surface. Therefore, the curved surface on the substrate to be transferred according to the present invention also means an uneven surface having no curved surface composed of only a plurality of planes, such as a tooth profile of a clog. Further, the curvature referred to in the present invention is:
The case of an infinite curvature (curvature radius = 0) that is angular like a periphery of a side or a vertex of a cube is also included. In addition, in order to make the surface of the transfer-receiving substrate have desired irregularities, press working, embossing, extrusion, cutting, molding, or the like may be used.

The material of the substrate to be transferred is arbitrary.
If it is a board material, a non-porcelain ceramic board such as a calcium silicate board, an extruded cement board, a slag cement board, an ALC (lightweight foamed concrete) board, a GRC (glass fiber reinforced concrete) board, a pulp cement board, a cedar, a pine, Wood veneer, wood plywood, particle board, laminated wood, medium density fiberboard (MDF) made of oak, lauan, teak, etc.
Wood plate, metal plate such as iron, aluminum, copper, etc.
Ceramics such as ceramics and glass, polypropylene, A
A resin molded product such as a BS resin or a phenol resin may be used.

Further, an easy-adhesion primer for assisting adhesion to an adhesive and a sealer for blocking exuding components such as alkali components exuding from the receiving substrate are previously provided on the surface of the substrate to be transferred. An agent or a sealing agent for sealing and sealing fine irregularities and porosity on the surface may be applied. A resin such as an isocyanate, a two-part curable urethane resin, an epoxy resin, an acrylic resin, or a vinyl acetate resin is applied as an easy-adhesion primer, a sealer, or a filler.

[Transfer Sheet] The transfer sheet is composed of a support and a transfer layer that transfers and transfers. The transfer layer comprises at least a decorative layer or a functional layer. Further, the adhesive may be formed on the transfer sheet as an adhesive layer that becomes a part of the transfer layer. In addition, in order to easily remove the residual air embraced between the transfer-receiving substrate surface and the transfer sheet,
If necessary, a large number of small holes may be formed in the entire surface of the transfer sheet so as to penetrate the entire layer of the transfer sheet.

(Support) As a support for the transfer sheet,
If the substrate to be transferred is a flat surface or a two-dimensional uneven surface, paper or the like without stretchability is also possible, but in order to apply the present invention to a three-dimensional uneven surface that exhibits its true value, it is necessary to stretch at least at the time of transfer. Use a flexible support. Due to the extensibility, the transfer sheet can adhere to and transfer to the inside of the concave portion on the surface of the substrate to be transferred when the collision pressure of the solid particles is applied. The stretchability of the entire transfer sheet is mainly governed by the stretchability of the support. Therefore, in addition to a conventionally known thermoplastic resin film, a rubber film that can be stretched even at normal temperature can be used as the support. In the case of a thermoplastic resin film, there is almost no stretchability when forming a transfer layer such as a decorative layer, and at the time of transfer, sufficient stretchability is exhibited by heating, and after cooling, the deformed shape is maintained, and the shape is restored by elasticity. A transfer sheet that can be used in the present invention can be easily prepared as a transfer sheet that does not cause the problem, similarly to a conventionally known ordinary transfer sheet.

As a specific example of the support, from the viewpoint of stretchability,
Even a biaxially stretched polyethylene terephthalate film, which has been widely used, can express necessary and sufficient stretchability by setting heating conditions, collision pressure conditions, and the like depending on the surface unevenness, so that curved surface transfer is possible. However, preferred supports that can easily exhibit stretchability at lower temperature and lower pressure include, for example, thermoplastic polyester resins such as ethylene terephthalate / isophthalate copolymer polyester and polybutylene terephthalate, polypropylene, polyethylene, and ethylene-propylene copolymer. Polymer, ethylene-
Polyolefin resin such as propylene-butene terpolymer, vinyl chloride resin, or natural rubber, synthetic rubber, olefin-based thermoplastic elastomer, etc., alone or as a mixture,
A resin film having a single layer or a plurality of different layers can be used. These resin films are preferably low stretched or unstretched. The thickness of the support used is usually 20 to 200.
μm.

If necessary, the support may be provided with a release layer on the transfer layer side in order to improve the releasability from the transfer layer. This release layer is peeled off from the transfer layer together with the support when the support is peeled off. As the release layer, for example, a simple substance such as a silicone resin, a melamine resin, a polyamide resin, a urethane resin, a polyolefin resin, a wax, or a mixture containing these is used.

If an uneven pattern is provided on the surface of the support that is in contact with the transfer layer, the uneven pattern can be formed on the surface of the transfer layer after the transfer. The uneven pattern is, for example,
There are hairline, line-shaped groove, uneven pattern of cleavage face of granite, wood grain conduit groove, wood grain ring pattern, cloth texture surface texture, skin squeezing, characters, geometric pattern and so on. The formation of the concavo-convex pattern is performed by embossing, sandblasting, or hairline processing the resin sheet of the support by hot pressing, or forming the ink (2) using a resin having a releasing property as a binder on the support. Liquid-cured urethane, silicone resin, melamine resin, polyfunctional acrylate or methacrylate monomer or prepolymer that crosslinks with ultraviolet light or electron beam, etc.). There is a method of providing a layer and forming a support having a shaping layer. The shaping layer has the function of the release layer.

(Transfer Layer) The transfer layer of the transfer sheet comprises at least a decorative layer or a functional layer, and a release layer, an adhesive layer or the like may be a component of the transfer layer as appropriate.
In the configuration having the adhesive layer, it is possible to omit applying the adhesive to one or both of the transfer sheet and the substrate to be transferred at the time of transfer.

The decorative layer is partially formed by a conventionally known method such as gravure printing, silk screen printing, offset printing or the like and a picture layer printed with a picture or the like by a material, a metal such as aluminum, chromium, gold or silver by a known vapor deposition method or the like. A metal thin film layer or the like formed on the target or on the entire surface, which is used according to the application. As the pattern, according to the surface irregularities of the substrate to be transferred,
A wood pattern, a stone pattern, a cloth pattern, a tile pattern, a brick pattern, a leather pattern, a character, a geometric pattern, a solid pattern, and the like are used. The picture layer ink is composed of a vehicle such as a binder, a coloring agent such as a pigment or a dye, and various additives appropriately added thereto. For the binder, a simple substance such as an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a polyurethane resin, a fluororesin, or a mixture containing these is used. As the pigment of the colorant, inorganic pigments such as titanium white, carbon black, red iron oxide, graphite, and ultramarine blue, and organic pigments such as aniline black, quinacridone, isoindolinone, and phthalocyanine blue are used. If the transfer substrate itself does not have a dyeing property, a receiving layer made of a known resin such as a polyester resin or an acrylic resin may be formed on the surface of the transfer substrate in advance. As the functional layer, a conductor layer (electromagnetic wave shielding layer,
An antibacterial agent or a fungicide such as zeolite powder carrying silver ions, 10,10'-oxybisphenoxyarsine, etc. are used. As the transfer layer,
Both the decorative layer and the functional layer may be used in combination.

The release layer may be provided between the support or the release layer and the decorative layer to adjust the releasability between the decorative layer and the surface of the decorative layer after transfer. This is the same as a conventionally known transfer sheet. For the release layer, for example, a resin or the like used as a binder for the picture layer ink is used. The release layer is transferred to the transfer-receiving substrate together with the decorative layer during transfer, and covers the surface of the decorative layer.

[Adhesive] The adhesive is used as an adhesive layer constituting a transfer layer of a transfer sheet or an adhesive layer on a substrate to be transferred.
Apply by online coating or offline coating before or immediately before transfer. When applied to a substrate to be transferred, the adhesive layer of the transfer sheet can be omitted. The adhesive to be used may be appropriately selected depending on the application, required physical properties, and the like. When a liquid is used as the solid particle accelerating fluid, an adhesive that is insoluble in the liquid is selected.

As the adhesive, for example, a heat-sensitive adhesive,
Moisture-curable heat-sensitive adhesives, hot-melt adhesives, moisture-curable hot-melt adhesives, two-component curable adhesives, ionizing radiation-curable adhesives, water-based adhesives, or pressure-sensitive adhesives with adhesives Various adhesives can be used.

As the heat-sensitive adhesive, any of a heat-sealing adhesive using a thermoplastic resin and a thermosetting adhesive using a thermosetting resin can be used. However, from the point that bonding is completed in a short time, a heat-fusion type (heat-sensitive adhesive)
Is preferred. The adhesive may be diluted with a solvent or without a solvent, or may be a liquid or a solid at room temperature, and may be used as appropriate. In the case of an adhesive other than a pressure-sensitive adhesive exhibiting tackiness, a transfer layer can be formed with only a single adhesive layer. If a coloring agent such as a pigment is added to the adhesive layer, it can be said that the entire layer is a decorative layer composed of a solid ink layer. Examples of the heat-sensitive adhesive include conventionally known adhesives such as vinyl chloride-vinyl acetate copolymer, acrylic resin, thermoplastic polyester resin, thermoplastic urethane resin, and polyamide resin obtained by condensation polymerization of dimer acid and ethylenediamine. Can be used. As the thermosetting adhesive, diallyl phthalate resin, thermosetting urethane resin, epoxy resin, or the like can be used.

The moisture-curable heat-sensitive adhesive is also a kind of heat-sensitive adhesive. The moisture-curable heat-sensitive adhesive is
Since the curing reaction proceeds with the moisture in the air when left naturally, it is applied immediately before transfer from the viewpoint of work stability. Immediately after transfer, the moisture-curable heat-sensitive adhesive has the same adhesive strength as a normal heat-melt adhesive, but the cross-linking / curing reaction gradually proceeds with moisture in the air due to natural standing. It is excellent in heat resistance without creep deformation and heat melting, and a large adhesive strength can be obtained. However, in order to promote crosslinking and curing of the adhesive by moisture after the transfer is completed, the decorative board after the transfer is left to cure in air containing moisture.

The moisture-curable heat-sensitive adhesive is a composition containing a prepolymer having an isocyanate group at a molecular terminal as an essential component. The prepolymer is usually a polyisocyanate prepolymer having one or more isocyanate groups at both molecular terminals, and is a solid thermoplastic resin at room temperature. Isocyanate groups react with each other due to moisture in the air to cause a chain extension reaction, and as a result, a reactant having a urea bond in a molecular chain is generated,
The urea bond further reacts with the isocyanate group at the molecular terminal to cause a biuret bond and branch to cause a crosslinking reaction.

The skeleton structure of the molecular chain of the prepolymer having an isocyanate group at the molecular terminal is arbitrary, and specific examples include a polyurethane skeleton having a urethane bond, a polyester skeleton having an ester bond, and a polybutadiene skeleton. Adhesive properties can be adjusted by appropriately employing one or more of these skeletal structures. When a urethane bond is present in the molecular chain, the terminal isocyanate group also reacts with the urethane bond to generate an allophanate bond, which also causes a cross-linking reaction.

The ionizing radiation-curable resin which can be used as the ionizing radiation-curable adhesive is a composition curable by ionizing radiation. Specifically, a radical polymerizable unsaturated bond or a cationic polymerizable functional group in the molecule is used. A prepolymer (including a so-called oligomer) having a group and / or a composition which is appropriately mixed with a monomer and curable by ionizing radiation is preferably used. These prepolymers or monomers are used alone or as a mixture of two or more.

Specifically, the above prepolymer or monomer contains a radically polymerizable unsaturated group such as a (meth) acryloyl group or a (meth) acryloyloxy group, or a cationically polymerizable functional group such as an epoxy group in the molecule. Consisting of a compound having Further, a polyene / thiol prepolymer based on a combination of a polyene and a polythiol is also preferably used. In addition, for example, a (meth) acryloyl group means an acryloyl group or a methacryloyl group.

Examples of the prepolymer having a radical polymerizable unsaturated group include polyester (meth) acrylate, urethane (meth) acrylate, epoxy (meth)
Acrylate, melamine (meth) acrylate, triazine (meth) acrylate and the like can be used. A molecular weight of about 250 to 100,000 is usually used.

Examples of the monomer having a radical polymerizable unsaturated group include monofunctional monomers such as methyl (meth)
Acrylate, 2-ethylhexyl (meth) acrylate, and the like. Further, as the polyfunctional monomer, there are trimethylpropane tri (meth) acrylate, dipentaerythritol hexa (meth) acrylate and the like.

Examples of the prepolymer having a cationically polymerizable functional group include prepolymers of epoxy resins such as bisphenol epoxy resins and novolak epoxy compounds, and vinyl ether resins such as fatty acid vinyl ethers and aromatic vinyl ethers. .

The thiol includes polythiols such as trimethylolpropane trithioglycolate and pentaerythritol tetrathioglycolate. Examples of the polyene include those obtained by adding allyl alcohol to both ends of a polyurethane made of a diol and a diisocyanate.

When curing with ultraviolet light or visible light, a photopolymerization initiator is further added to the ionizing radiation-curable resin. In the case of a resin system having a radical polymerizable unsaturated group, acetophenones, benzophenones, thioxanthones, and benzoins can be used alone or in combination as a photopolymerization initiator. In the case of a resin having a cationically polymerizable functional group, an aromatic diazonium salt, an aromatic sulfonium salt, an aromatic iodonium salt, a metallocene compound, or the like can be used alone or as a mixture as a photopolymerization initiator. The addition amount of these photopolymerization initiators is about 0.1 to 10 parts by weight based on 100 parts by weight of the ionizing radiation-curable resin.

As the ionizing radiation, electromagnetic waves or charged particles having energy capable of crosslinking the molecules in the adhesive are used. Usually, ultraviolet rays or electron beams are used, but visible rays, X-rays, ion beams, or the like can also be used. As the ultraviolet light source, a light source such as a high-pressure mercury lamp, a low-pressure mercury lamp, a carbon arc lamp, and a black light is used. The wavelength of the ultraviolet light is usually 190
The wavelength range of ３380 nm is mainly used. As the electron beam source, various types of electron beam accelerators such as Cockcroft-Walton type, Van degraft type, resonance transformer type, insulating core transformer type, or linear type, dynamitron type, high frequency type, etc. are used, preferably 100 to 1000 keV, preferably. Is 100
A device that irradiates electrons having an energy of about 300 keV is used.

If necessary, a thermoplastic resin such as a vinyl chloride-vinyl acetate copolymer or an acrylic resin may be added to the ionizing radiation-curable resin. If used without adding a diluting solvent, it becomes a hot melt adhesive.

When an ionizing radiation-curable adhesive is used, an ionizing radiation irradiating device for irradiating an ultraviolet ray or an electron beam can be incorporated in the manufacturing apparatus. The irradiation is performed during, after, or after and after the application of the collision pressure.

Further, various additives may be added to the various resins used for the adhesive, if necessary. These additives include, for example, extenders (fillers) composed of fine powders such as calcium carbonate, barium sulfate, silica, and alumina, and thixotropic agents such as organic bentonite (especially for transfer-receiving substrates having a large uneven step). In this case, the adhesive may be added to prevent the adhesive from flowing into the concave portion from the convex portion.).

To apply the adhesive to a sheet such as a transfer sheet or a substrate to be transferred, a solvent (or dispersion medium) such as water or an organic solvent is used.
In the form of a solution (or dispersion) dissolved (or dispersed) in
Alternatively, a hot-melt thermoplastic composition or a room-temperature liquid uncured resin is applied in the form of a solvent-free resin liquid. As a coating method,
What is necessary is just to apply by the solution coating by gravure roll coat etc. which is a conventionally well-known coating method, or the melt coating (melt coating) method by an applicator etc. When used without adding a diluting solvent, solvent drying is unnecessary. For example, heat-sensitive adhesives can be used as solventless hot-melt adhesives, respectively. In addition, an ionizing radiation-curable adhesive or the like can be applied without a solvent. When used as a hot-melt adhesive, there is no solvent, so solvent drying is unnecessary even immediately before transfer, and high-speed production is possible. The amount of the adhesive applied varies depending on the composition of the adhesive, the type of the substrate to be transferred, and the surface state.
Usually, it is about 10 to ²⁰⁰ g / m ² (solid content).

It is to be noted that a heat-sensitive adhesive is used as the adhesive,
The timing of heating to activate and heat-bond the adhesive may be before applying the collision pressure, during the application of the collision pressure, or before and during the application of the collision pressure. The heating of the adhesive is performed by heating the transfer sheet or the substrate to be transferred. The material to which the adhesive has been applied (the transfer sheet or the substrate to be transferred) may be heated, the material to which the adhesive is not applied may be heated, or both materials may be heated. Good. Also,
For the heating during the application of the collision pressure, heated solid particles or a fluid for accelerating the solid particles may be used as the heating fluid.

On the other hand, if the transfer sheet follows the surface shape of the substrate to be transferred and is formed, and the adhesive is sufficiently activated, the cooling of the adhesive may be promoted by cooling means such as cold air. Cold air is blown from the transfer sheet side or the transfer-receiving substrate side. In addition, cooling solid particles and cooling fluid can also be used as cooling means. The promotion of cooling also prevents the transfer sheet formed following the inside of the concave portion of the concave-convex surface of the transfer-receiving substrate from returning to the case where there is a restoring force after releasing the collision pressure.

[Solid Particles] Examples of solid particles include non-metallic inorganic particles such as glass beads, ceramic beads, alumina beads, zirconia beads, corundum beads, and alundum beads, iron or carbon steel, and stainless steel. Such as iron alloys, aluminum, aluminum alloys such as duralumin, titanium, metal particles such as metal beads such as zinc, or fluororesin beads, nylon beads,
Organic particles such as resin beads such as silicone resin beads, urethane resin beads, urea resin beads, and crosslinked rubber beads, or inorganic substances composed of resin and inorganic particles such as metals.
Resin composite particles and the like can be used. The shape is preferably spherical, but spheroidal, polyhedral, scaly,
Amorphous and other shapes can also be used. The particle size of the solid particles is usually about 10 to 1000 μm.

The solid particles can also serve as heating means and cooling means. When heated solid particles are used, the activation of the adhesive by heating and the promotion of crosslinking and curing thereof, or the improvement of the stretchability by heating the transfer sheet can be performed together with the pressing of the transfer sheet. In this case, the transfer sheet and the substrate to be transferred may be heated to some extent by another heating method before the application of the collision pressure. The heated solid particles can also be used to maintain the temperature of the already heated transfer sheet, substrate to be transferred, and the like. On the other hand, for the purpose of promoting cooling after bonding, solid particles having a temperature lower than the temperature of the adhesive at the time of bonding can be used as the cooling solid particles. The solid particles may be used in combination with a part or all of the solid particles as heated solid particles or cooled solid particles, or after colliding heated solid particles with cooled solid particles. In addition, a transfer sheet, a substrate to be transferred, an adhesive or the like that needs to be heated by another heating method is sufficiently heated, and the molding, bonding and cooling of the transfer sheet are performed almost simultaneously using cooling solid particles. You can do it too.

In order to heat or cool the solid particles, when the solid particles are stored in a tank such as a hopper or the like, an electric heater provided in the tank or on the outer wall of the tank, a heating means using heated steam, a refrigerant, or a cooling means It should be done in. Further, these means may be provided on the outer wall of the solid particle transport tube to heat or cool the solid particle transport tube. Alternatively, when a fluid is used for accelerating the solid particles, the solid particles can be cooled or heated by heat conduction from the fluid using a cooled or heated fluid. In this case, by causing the fluid to collide with the transfer sheet, the fluid can be used as heating or cooling means together with the solid particles. Alternatively, in the case where the fluid is a liquid and a tank for storing solid particles together with the liquid is used, the solid particles and the liquid may be cooled or heated during storage.

[Application of Impact Pressure by Solid Particles] In order to strike the solid particles against the transfer sheet and apply the impact pressure to press the transfer sheet against the substrate to be transferred, the solid particles are ejected from the solid particle ejection means for ejecting the solid particles. The particles are ejected toward the transfer sheet to apply a collision pressure to the transfer sheet. As the solid particle ejecting means, for example, an ejector using a rotating impeller (see FIGS. 3 to 6) or an ejector using an ejection nozzle (see FIG. 7) is used as a particle accelerator. The ejector using the impeller accelerates and ejects solid particles by rotation of the impeller. On the other hand, an ejector using a blowing nozzle uses a solid particle acceleration fluid to accelerate and transport solid particles with a high-speed fluid flow of the fluid and eject the solid particles together with the fluid. Sandblasting, shot blasting, shot peening and the like used in the blasting field can be used for the impeller and the blowing nozzle. For example, a centrifugal blast device is used for the impeller, and a pressurized or suction blast device, a wet blast device, or the like is used for the blowing nozzle. A centrifugal blast device accelerates and ejects solid particles by the rotational force of an impeller. The pressurized blast device ejects solid particles mixed with compressed air together with air. The suction-type blast device sucks solid particles into a negative pressure portion generated by a high-speed flow of compressed air, and ejects the solid particles together with the air. The wet blast device mixes and ejects solid particles with a liquid.

As the means for ejecting solid particles, a method of accelerating solid particles using free fall due to gravity, a method of accelerating magnetic particles by a magnetic field, and the like may be employed other than the blowing nozzle and the impeller. Is also possible. In the case of an impeller, a solid particle ejecting unit using gravity and a magnetic field, the solid particles can be ejected toward the transfer sheet in a vacuum.

[Ejector: Impeller] FIGS. 3 to 6 are explanatory views showing an example of an impeller which can be used as a particle accelerator of the ejector. This impeller corresponds to a centrifugal blast device used in the blasting field.

In the drawing, the impeller 812 includes a plurality of blades 8.
13 is fixed on both sides by two side plates 814, and the center of rotation is a hollow portion 815 without blades 813. Further, a direction controller 816 is provided inside the hollow portion 815. The direction controller 816 has a hollow cylindrical shape having an opening 817 that is partially open in the circumferential direction.
The rotation axis is the same as the rotation axis 12 and is rotatable independently of the impeller. The direction controller 816 fixes the opening 817 in a predetermined direction when used. Further, a hollow impeller 8 is provided inside the direction controller 816.
Another impeller having the same rotation axis as the twelve rotation axes is included as a sprayer 818 (see FIG. 5). Sprayer 818
Rotates with the outer impeller 812. A rotating shaft 819 is fixed to the center of rotation of the side plate 814. The rotating shaft 819 is rotatably supported by a bearing 820, and is driven and rotated by a rotating power source (not shown) such as an electric motor. The impeller 812 rotates. The rotation shaft 819 is
It does not penetrate between the two side plates 814 having the blades 813 therebetween, and forms a space without a shaft.

Then, the solid particles P
Is supplied from a hopper or the like through a transport pipe. Usually, the solid particles P are supplied from above (directly above or obliquely above) the impeller 812. The solid particles P supplied into the sprayer 818 scatter outside by the impeller of the sprayer 818. The scattered solid particles P are emitted only in the direction allowed by the opening 817 of the direction controller 816, and supplied between the blades 813 of the outer impeller 812. Then, it collides with the impeller 813, is accelerated by the rotational force of the impeller 812, and jets out from the impeller 812.

The direction in which the solid particles are ejected is substantially vertically downward as shown in FIGS. 3 and 4, but may be horizontally or obliquely downward (not shown). 6A and 6
FIG. 6B is a conceptual diagram of the ejection direction control for adjusting the ejection direction of the solid particles P by setting the direction of the opening 817 of the direction controller 816 (FIGS. 6A and 6B).
Are fixed at the illustrated positions). Note that the direction controller 816 can also adjust the ejection amount of the solid particles P by adjusting the size of the opening 817 in the circumferential direction and the width direction.

In FIG. 3, the rotation shaft 819 is configured so as to be only outside the side plate 814 and not penetrate to the hollow portion 815. Penetrating to the hollow part 815,
It is also possible to adopt a configuration in which the inside of a hollow cylindrical rotary shaft provided with an opening for passing solid particles on the outer periphery is a hollow part (not shown).

The shape of the blade of the impeller is typically a rectangular flat plate (a rectangular parallelepiped) as shown in FIGS. 3 to 6, but other than this, a curved curved plate, a propeller shape such as a screw propeller, or the like may be used. It is also possible to select according to the application and purpose. Further, the number of blades is usually selected from a plurality of blades in a range of up to about 10 blades. And the shape of the impeller, the number of blades, the rotation speed, the mass and supply speed and supply direction of the solid particles,
The ejection direction, ejection speed, projection density, ejection diffusion angle, etc. of the accelerated solid particles are adjusted by the combination of the opening size and orientation of the direction controller.

Further, the impeller described above is further provided with an ejection guide (not shown) for opening only a portion for ejecting and ejecting the solid particles and covering the periphery of the impeller as needed. And the ejection direction of solid particles can be controlled. The shape of the opening of the ejection guide is, for example, a hollow cylindrical shape, a polygonal column shape, a conical shape, a polygonal pyramid shape, a fish tail shape, or the like.

The dimensions of the impeller are usually about 5 to 60 cm in diameter, the width of the impeller is about 5 to 20 cm, the length of the impeller is about the diameter of the impeller, and the rotation speed of the impeller is 500 to 4000 r.
pm. The ejection speed of the solid particles is 10 to 50 m /
s, and the projection density is about 10 to 150 kg / m ² .

The material of the blades of the impeller may be appropriately selected from ceramics, metals such as steel, high chromium cast steel, titanium, and titanium alloy, depending on the type of solid particles. Solid particles are accelerated by contact with the blades, so when metal beads or inorganic particles are used for the solid particles, the particles are hard, so the blades should be made of high-chromium cast steel or ceramic with good wear resistance. . When resin beads are used as the solid particles, steel may be used because they are softer than metal particles.

[Blowing Nozzle] FIG. 7 shows an example of a blower 840 using a blowing nozzle as a solid particle blowing means for blowing solid particles together with a fluid. Note that the ejector 840 shown in the figure uses gas as a solid particle accelerating fluid,
It is an example of an ejector in a form in which the gas and the solid particles are mixed and ejected when the solid particles are ejected. The ejector 840 shown in the figure includes an induction chamber 841 for mixing the solid particles P and the fluid F, and an induction chamber 8
The nozzle 41 includes an internal nozzle 842 for ejecting the fluid F into the nozzle 41, and an ejection nozzle 844 for ejecting the solid particles P and the fluid F from the nozzle opening 843. Fluid F sent from a compressor or a blower (not shown) through a pressurized tank (not shown) as appropriate,
Blowing nozzle 8 from internal nozzle 842 through induction chamber 841
When jetting from the nozzle opening 843 of the nozzle 44, the guiding chamber 8
At 41, a negative pressure is created by the action of the fluid flow flowing at high speed, and the negative pressure guides and mixes the solid particles into the fluid flow, accelerates and transports the solid particles with the fluid flow, and causes the nozzle opening 843 of the blowing nozzle 844 to flow. And is ejected together with the fluid flow.

It should be noted that there are blow nozzles which use a liquid as a solid particle accelerating fluid. In the case of liquid, the fluid and solid particles are mixed and stored in a pressurized tank (not shown) by, for example, a pump (not shown, when the fluid is a liquid), and the mixed liquid is discharged from the nozzle opening of the blowing nozzle. What gushes etc. is used.

Examples of the shape of the nozzle opening include a hollow cylinder, a polygonal column, a cone, a polygonal pyramid, and a fish tail. The fluid pressure is generally about 0.1 to 100 kg / cm ^{2 in} spray pressure. The flow velocity of the fluid flow is usually about 1 to 20 m / sec for the liquid flow, and is usually about 5 to 80 m / sec for the air flow.

The material of the ejector such as the induction chamber and the nozzle may be appropriately selected from ceramics, steel, titanium, titanium alloys and the like according to the type of solid particles and fluid. If the fluid is a liquid, select a material that does not cause rust, dissolution, corrosion, etc. For example, if the fluid is water, stainless steel, titanium,
Uses titanium alloy, synthetic resin, and ceramic. However,
If the surface is waterproofed, steel or the like may be used.

The solid particles pass along the inner wall of the ejector. When metal beads or inorganic particles are used as the solid particles, the particles are hard. It is preferable to use steel or the like whose surface is coated with ceramics. When resin beads are used as the solid particles, carbon beads (ordinary steel) may be used because they are softer than metal particles.

[Fluid] The fluid is used when the solid particles are accelerated and conveyed by the fluid flow, and the solid particles are ejected together with the fluid from the solid particle ejection means (eg, a blowing nozzle). The fluid is a solid particle acceleration fluid that accelerates the solid particles. Either a gas or a liquid can be used as the fluid, but usually a gas that is easy to handle is used. The gas is typically air, but may be carbon dioxide, nitrogen or the like. On the other hand, the liquid is not necessarily limited, but is nonflammable,
Water is one of the preferred materials because of its ease of drying, non-toxicity, low cost, and availability. In addition, nonflammable liquids such as chlorofluorocarbon can be used. Liquids (as well as gases)
Can collide with the transfer sheet together with the solid particles.

[Collision Pressure Applied Form] Although only one jetting device can be used depending on the area of the collision pressure applying area, if a required area is large, a plurality of ejectors are used to impinge on the transfer sheet. The region may have a desired shape. For example, a plurality of rows are arranged in a straight line in the width direction perpendicular to the feeding direction of the transfer sheet and the transfer-receiving base material, so that the collision area has a band shape that is linear and wide in the width direction. Or,
Even if the ejectors 32 are arranged in a staggered pattern as shown in FIG. 8A or the ejectors 32 are arranged in a row as shown in FIG. May be arranged so as to collide on the upstream side. In the arrangement shown in FIG. 8B, the pressing of the transfer sheet against the transfer substrate by the collision pressure starts from the center in the width direction and gradually presses toward both ends in the width direction. With this configuration, it is possible to prevent the transfer sheet from adhering to the transfer-receiving substrate while air is held in the central portion in the width direction. When a plurality of the ejectors 32 are arranged in the width direction as shown in FIGS. 8A and 8B, the pressurized regions of the individual ejectors 32 partially overlap with each other, so that the pressure can be completely applied over the entire width. It is preferable to arrange them.
FIG. 8B shows an example of such an arrangement, in which a dotted line indicates a pressurized region. In order to lengthen the collision pressure application time, it is preferable that the ejectors are arranged in a multistage arrangement in which two or more rows are arranged in the feed direction of the transfer sheet and the substrate to be transferred.

[Use of Chamber] By the way, when solid particles are actually used, it is preferable that the solid particles are not scattered in the surrounding atmosphere and are circulated and reused. Therefore, continuous transfer is performed while preventing scattering of solid particles and circulating and recycling the solid particles using the chamber. in this case,
Solid particles in a state in which the transfer sheet is pressed on the outer sides of both sides of the base material to be transferred by a rotating roller or an endless belt having a peripheral speed synchronized with the transfer speed of the base material transfer means to seal a gap with the base material transfer means. It is desirable to apply the collision pressure of the solid particles while preventing the solid particles behind the transfer layer side of the transfer sheet from adhering to the side surface and the back surface of the substrate to be transferred. The solid particles dropped and collected below the chamber are temporarily stored in a hopper if necessary, and then supplied to the solid particle ejection means again.

[Use of Transfer Product] The use of the transfer product such as the decorative material obtained in the present invention is such that the transferred decorative surface has an uneven surface,
In particular, it can be used for various applications such as an article having an uneven surface such as a three-dimensional shape. For example, as a cosmetic material, exterior walls such as siding, fences, roofs, gates, exteriors such as gable boards, wall surfaces,
Interior decoration of buildings such as ceilings and floors, window frames, doors, handrails, sills, surface decorations of fittings such as sills, furniture such as chests of drawers, surface decorations of cabinets for light electric / OA equipment such as television receivers, automobiles It can be used in various fields such as vehicle interior materials such as trains and interior materials such as aircraft and ships. The decorative material is used as a decorative board or the like. In addition, the shape of the transfer product including the cosmetic material is arbitrary such as a flat plate, a curved plate, a rod-shaped body, and a three-dimensional object.

[Post-processing] In addition, a transparent protective layer may be further applied to the surface of the transferred product such as a cosmetic material after the transfer in order to impart durability, design feeling and the like. As such a transparent protective layer, a fluororesin such as polyvinylidene fluoride, an acrylic resin such as polymethyl methacrylate, a silicone resin, a binder of one or more of urethane resins, and the like, if necessary, Benzotriazole,
UV absorbers such as ultrafine cerium oxide, light stabilizers such as hindered amine radical scavengers, lubricating agents such as silica, α-alumina (spherical, scale or amorphous) particles, coloring pigments, extender pigments, lubricants, etc. Use the added paint. Also,
For exterior use, inorganic paints can also be used. Coating is performed by spray coating, flow coating, roll coating using a soft rubber roll or sponge roll, or the like. The thickness of the transparent protective layer is about 1 to 100 μm.

On the other hand, the release layer was formed of a composition obtained by removing the coloring pigment from the binder resin of the picture ink, and was formed to a thickness of 2 μm (when dried).

Using the above-mentioned substrate to be transferred and the transfer sheet, transfer was performed using a transfer apparatus shown in FIG. First, the base material B to be transferred is placed on the base material conveying device 11 composed of a conveyor belt, and is preheated by the heating device 21 so that the line speed 25 is set.
m / min. Then, the transfer sheet S unwound from the unwinding roll 12 was pressed against the transfer base material B by a rubber pressing roller 13 and temporarily press-bonded, and supplied integrally with the transfer base material B into the chamber 30. In the first chamber 30,
The transfer sheet S was softened by preheating and the adhesive was activated by using the heated residual heat of the transfer-receiving base material B. In this case, the heating conditions of the heating device 21 were adjusted such that the surface temperature of the support became 100 ° C. As the heating device 21, a device that blows out hot air from a nozzle was used.

Next, the solid particles P have an average particle size of 0.4

The rotation speed of the impeller of the ejector 32 is 3600 rpm, and the ejection speed of the solid particles P is 35 m.
/ S, and the projection density was 100 kg / m ² . And
Most of the solid particles P that collided with the transfer sheet S fall around the both ends of the conveyor belt of the base material transport device 11 and fall into the lower chamber 33, are transported to the original hopper 31, and are reused. Further, the solid particles P remaining without dropping were transported downstream while being placed on the support of the transfer sheet S.

At the time when the substrate B to be transferred is unloaded from the first chamber 30, the transfer sheet S is stretched following the surface of the fine unevenness 403 in the flat convex portion 402, and is heat-sealed. The transfer sheet S is not in contact with the groove-shaped recess 401. Transferred substrate B from chamber 30

Subsequently, the transferred substrate B is heated by the heating device 23 before it is carried into the next chamber 34.
On the other hand, only the support n having the same material and thickness as that used for the transfer sheet S is unwound from the unwind roll 16, and is pressed by the pressing roller 17 so as to cover the transferred transfer layer of the base material B to be transferred. Then, in the pressed state, the substrate to be transferred B and the support n were supplied into the chamber 34. In the chamber 34, the solid particles P were ejected under the same conditions as those performed in the first chamber 30. In the figure, 35 is a hopper, 36 is an ejector, 37
Is the lower chamber, which has the same structure as in the first chamber 30.

The solid particles P are ejected in the chamber 34,

Then, the same sealing treatment and adhesive application as in Example 1 were performed. On the other hand, the same transfer sheet as in Example 1 was prepared.

In this embodiment, the transfer was performed using the transfer device shown in FIG. The process up to the peeling roller 14 through the chamber 30 is exactly the same as that of the first embodiment. Thereafter, the support m peeled off by the peeling roller 14 is bypassed by the guide rollers 41 and 42 without being wound, and the transferred substrate B is reheated by the heating device 23. Then, the support pair m once peeled off and the base material B to which the transfer layer has been transferred are pressed against the transfer roller B by the pressing roller 17, and thereafter, the inside of the chamber 34 is passed as in the first embodiment. The support m was peeled again through the roller 18 and wound on the take-up roll 15.
