DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method of manufacturing a ceramic body with a picture, and more particularly, to a simple method of manufacturing a ceramic body with a picture which can be used as a building material such as an art tile, a ceramic photo and the like.

[0002]

2. Description of the Related Art A ceramic body with a picture, in which black and white and color images are formed on a ceramic body such as a ceramic plate, is used not only for building materials such as art tiles used for walls such as bathrooms and entrances, but also for ceramic photographs such as portraits and remains. It is expected to be applied to various uses such as accessories such as pendants and brooches. Conventionally, as a method of forming an image on the surface of a ceramic plate or the like, after forming an image on a normal photographic paper, the paper portion of the photographic paper is removed and adhered to the ceramic surface, and the image portion surface is cured with an ultraviolet curable resin. There is known a method of protecting the image portion by laminating the image portion. However, when an image is formed by this method, the light resistance and heat resistance of the image portion are insufficient.
If the image is excellent in light resistance and heat resistance and the image can be stored semi-permanently, applications can be advantageously expanded.

For example, JP-A-2-252683 discloses a method in which a photosensitive film is adhered to the surface of ceramics,
A method has been proposed in which halftone exposure is performed through a color-separated lith film, the film is developed, and an inorganic pigment for painting is successively placed and fired in accordance with the appearing image. JP-A-62-246887 discloses that a photosensitive polymer is applied directly on a ceramic in place of the photosensitive film, exposed to halftone dots, developed, and treated in the same manner as described above. Methods of forming and firing have been proposed. The images (porcelain photographs) formed by these methods are extremely preservable and semi-permanent. However, when the above method is used, a plurality of squirrel films in which a color original is color-separated must be produced. Also, when attaching the pigment to the surface of the developed photosensitive film, it is necessary to finely adjust the amount of pigment, poor reproducibility,
In many cases, the production must be repeated. Further, the formation and firing of each pigment layer must be repeated. Therefore, the method has a problem that the operation is extremely complicated and the manufacturing cost is high.

[0004] A method has also been proposed in which printing is performed on transfer paper with an ink mainly composed of a painting pigment by screen printing or gravure printing, and the transfer paper is adhered to porcelain and fired. . The image formed by the above method is also excellent in durability and is semi-permanent in the same manner as described above. The firing must be repeated. Therefore, as in the above-described method, there is a problem that the operation is extremely complicated and the manufacturing cost is high. Further, since the pigments for painting tend to cause clogging of the screen mesh, the screen mesh cannot be made sufficiently small. As a result, it is difficult to reproduce a clear photograph-like image having excellent resolution. There's a problem.

Further, in order to form an image having good storability on a ceramic body, it is necessary to sinter the image formed with the inorganic pigment on the ceramic body. You also need to make a choice.

[0006]

Examples of the plastic sheet include a polyethylene terephthalate sheet, a polycarbonate sheet, a polyethylene sheet, a polyvinyl chloride sheet, a polyvinylidene chloride sheet, a polystyrene sheet, a styrene-acrylonitrile sheet,
A polyester sheet can be used. Further, as the paper support, printing paper, coated paper or the like having good smoothness can be used. In the case where the image formed of the transfer material is arranged together with the entire image receiving sheet in the arrangement step,
Since the support needs to be evaporated and / or incinerated in the sintering process, the support may include atoms or compounds that do not disappear by evaporation or combustion in the sintering process, or may react with the pigment to change its color. It is preferably free of atoms or compounds.

It is preferable that the support of the image receiving sheet has minute voids (voids), since curling can be prevented and image quality can be improved. Such a support is, for example, a thermoplastic resin, a mixed melt obtained by mixing an inorganic pigment or a filler made of an incompatible polymer with the thermoplastic resin, a single-layer or multi-layer by a melt extruder. It can be produced by forming a film and stretching it uniaxially or biaxially. In this case, the porosity is determined by the selection of the resin and the filler, the mixing ratio, the stretching conditions, and the like.

As the thermoplastic resin, a polyolefin resin such as polypropylene and a polyethylene terephthalate resin are preferable because of good crystallinity, good stretchability and easy void formation. It is preferable to use the above-mentioned polyolefin resin or polyethylene terephthalate resin as a main component, and appropriately use a small amount of another thermoplastic resin in combination. As the inorganic pigment used as the filler, those having an average particle size of 1 μm or more and 20 μm or less are preferable, and calcium carbonate, clay, diatomaceous earth, titanium oxide, aluminum hydroxide, silica and the like can be used. When polypropylene is used as the thermoplastic resin as the incompatible resin used as the filler, it is preferable to combine polyethylene terephthalate as the filler. In the support of the image receiving sheet,
The content of a filler such as an inorganic pigment is generally about 2 to 30% by volume.

The thickness of the support of the image receiving sheet is usually 1
It is 0 to 400 μm, preferably 25 to 200 μm. Further, the surface of the support is subjected to a surface treatment such as a corona discharge treatment or a glow discharge treatment in order to enhance the adhesion with the image receiving layer (or the cushion layer) or the adhesion with the image forming layer of the thermal transfer sheet. May be.

On the surface of the image receiving sheet, one or more image receiving layers are provided for transferring a transfer material from a transfer layer and fixing the same. The image receiving layer is preferably a layer formed mainly of an organic polymer binder. The binder is preferably a thermoplastic resin, for example, acrylic acid, methacrylic acid, acrylate,
Homopolymers and copolymers of acrylic monomers such as methacrylic acid esters and the like, methylcellulose, ethylcellulose, cellulose polymers such as cellulose acetate, polystyrene, polyvinylpyrrolidone, polyvinylbutyral, polyvinylalcohol, vinyl such as polyvinyl chloride Examples include homopolymers and copolymers of the system monomers, condensation polymers such as polyesters and polyamides, and rubber polymers such as butadiene-styrene copolymers. The binder of the image receiving layer is used in order to obtain an appropriate adhesive strength with the transfer material.
Preferably, the polymer has a glass transition temperature (Tg) lower than 90 ° C. For this purpose, it is also possible to add a plasticizer to the image receiving layer. Further, the binder preferably has a Tg of 30 ° C. or higher in order to prevent blocking between sheets. As the binder of the image receiving layer, the same as the binder contained in the transfer layer, in terms of improving the adhesion with the transfer layer during transfer recording, and improving the sensitivity and image strength,
Or it is particularly preferable to use a similar polymer.

The thickness of the image receiving layer is generally from 0.3 to
7 μm, preferably 0.7 to 4 μm.

It is preferable that the image receiving sheet can be adhered to the surface of the ceramic body because the operation becomes easy even when a ceramic body having a curved surface such as a dish or a bottle is used. As the image receiving sheet, a layer composed of a water-soluble polymer (hereinafter, sometimes referred to as a “water-soluble polymer layer”) and an image receiving layer composed of a hydrophobic polymer (hereinafter, referred to as a “hydrophobic polymer layer”) are formed on a support. (Hereinafter, may be referred to as an “adhesive image-receiving sheet”). Examples of the support include a paper support, polyethylene terephthalate, polyamide, polycarbonate, glassine paper, cellulose ester, fluoropolymer, polyether, polyacetal, polyolefin, polyimide, polyphenylene sulfide, polypropylene, polysulfone, cellophane, polyethylene terephthalate, and the like. Can be When the support is a plastic film, it is preferable to have a release layer containing silicone, a higher fatty acid, a fluorine-based compound, or the like on the surface (the surface on which the water-soluble polymer layer is formed), Further, it may be composed of only the release layer.

When the support is a paper support, when the image receiving sheet is immersed in water, a part of the water-soluble polymer is dissolved and the hydrophobic polymer layer can be peeled off from the paper support. At the same time, it is preferable that the peeled hydrophobic polymer layer can be bonded to the surface of a ceramic body such as a ceramic plate. As such a water-soluble polymer, for example, polymers used for painting ceramics, such as dextrin and gum arabic, polyvinyl alcohol, carboxymethylcellulose, methylcellulose, hydroxyethylcellulose, and gelatin are preferable. Examples of the hydrophobic polymer include polyvinyl butyral resin, ethylene-vinyl acetate copolymer, ethylene-acrylate copolymer, styrene-acrylate copolymer, and styrene-maleic acid-acrylate copolymer. Thermoplastic resins such as polymers, polyamides, polystyrenes, polyesters, polyvinyl acetate resins, cellulose derivatives, polystyrene methacrylic resins, polyvinyl ether resins, polyurethane resins, polycarbonate resins, and rosin resins. Further, a resin used as an overprint lacquer for overcoating a ceramic body such as a ceramic body is preferably used, and examples thereof include an acrylic resin and a urethane resin.

As described above, the image receiving layer may be formed on the surface of the ceramic body. When the image receiving layer is formed on the surface of the ceramic body, the transferability promoting material is applied imagewise to at least one of the transfer layer surface of the transfer sheet and the image receiving layer surface of the ceramic body. The components in the image receiving layer when the image receiving layer is formed on the surface of the ceramic body are as described above.

In the latent image forming step, when a transferability-enhancing material is applied imagewise to the transfer layer surface or the image-receiving layer surface to form a latent image, the transfer property of the transfer material constituting the transfer layer Only the part of the latent image with the accelerating material attached,
The transferability-promoting material penetrates into the transfer layer, and the binding of the binder constituting the layer is loosened, and the binding force between the support and the transfer layer is reduced, and the transferability to the image receiving sheet is improved. It becomes possible to transfer at a temperature.

In the transfer step performed after the latent image forming step, the transfer material is transferred from the transfer layer to the image receiving layer according to the formed latent image, and an image made of the transfer material is formed on the image receiving layer surface. . In the transfer step, at least the transfer layer and the image receiving layer are brought into contact with each other, and the transfer material in the transfer layer is transferred onto the image receiving layer only in a region to which the transferability promoting material is provided. At the time of transfer, it is preferable to apply pressure while applying heat. In the embodiment using the image receiving sheet, for example, the transfer step can be performed using a pair of heating nip rollers incorporating a heating unit such as a heater.

When the image receiving layer is not formed on the ceramic body, after the latent image forming step and the transferring step, the image formed of the transfer material formed on the image receiving sheet is arranged on the surface of the ceramic body. As the image receiving sheet,
When the image receiving layer uses a sheet containing a thermoplastic resin as a binder, the image receiving layer of the image receiving sheet is heated and pressed on the surface of the ceramic body, so that the image made of the transfer material is arranged on the surface of the ceramic body together with the image receiving sheet. can do. At the time of thermocompression bonding, the image made of the transfer material may be arranged so as to face the surface of the ceramic body, or the image receiving layer may be arranged so as to be sandwiched between the ceramic body and the image made of the transfer material. When the images made of the transfer material are arranged to face each other, a reverse image of the desired image is formed on the image receiving sheet.

When an adhesive image receiving sheet having a paper support is used, after the latent image forming step and the transferring step,
Part of the adhesive image-receiving sheet is immersed in water to partially dissolve the polymer of the water-soluble polymer layer, and peel off the hydrophobic polymer layer from the paper support, and place the peeled hydrophobic polymer layer on the surface of the ceramic body. The image formed of the transfer material and the transfer material can be attached to the surface of the ceramic body together with the image receiving layer. When an adhesive image-receiving sheet having a plastic film support is used, the surface of the film is subjected to a surface treatment for forming a release layer in advance, as described above, so that the image is formed without being immersed in water. The polymer layer can be peeled from the film support. The peeled hydrophobic polymer layer can be bonded to the surface of a ceramic body such as a ceramic plate via an adhesive layer.

When the image formed of the transfer material formed on the adhesive image receiving sheet is arranged on the surface of the ceramic body, the image may be inverted. That is, after forming a reversal image on the image receiving layer in advance, the image portion may be arranged on the surface of the ceramic body by facing the surface of the ceramic body (reversing the image again). In this case, since the hydrophobic polymer layer is not interposed between the image and the surface of the ceramic body, the sintering of the inorganic pigment and the ceramic body proceeds more stably in the subsequent sintering step, which is preferable. Since the surface of the hydrophobic polymer layer (the surface on which the image formed of the transfer material is formed) does not have adhesiveness, when the ink image is arranged so that the image faces the ceramic body surface as described above, it is necessary to use the ceramic material. It is preferred to apply an adhesive water-soluble polymer to the body surface.

Further, after transferring an image formed of a transfer material formed on an image receiving layer (a layer made of a thermoplastic resin or the like) of the image receiving sheet having no adhesive property to the image receiving layer of the adhesive image receiving sheet, As described above, after partially immersing the adhesive image-receiving sheet (adhesive sheet having a paper support) in water, the paper support is peeled off, and an image formed of a transfer material together with a hydrophobic polymer layer on the surface of the ceramic body. Can also be arranged.

In the sintering step, the ceramic body on which the image of the transfer material is formed is heated, and the inorganic pigment contained in the transfer material is sintered on the surface of the ceramic body. The inorganic pigment is sintered on the surface of the ceramic body, and components other than the inorganic pigment in the transfer material and components such as an image receiving layer disposed on the surface of the ceramic body together with the image are evaporated or incinerated. The heating of the ceramic body is preferably performed using, for example, an electric kiln from the viewpoint of temperature control, color development, and the like. The heating conditions can be appropriately set according to the selected material, the volume of the ceramic body, the size of the image, and the like. Heating may be performed by gradually increasing the temperature to the firing temperature, or after heating at a constant temperature of 300 ° C. to 500 ° C. for a certain time,
Preferably, the temperature is gradually increased to the firing temperature. In the case of using a paint as the inorganic pigment, the baking temperature is usually 650 ° C to 900 ° C, preferably 750 ° C to 850 ° C.
C. and the firing time is preferably 1 to 8 hours. When an undercolor is used as the inorganic pigment, the firing temperature is set to 1000 ° C to 1300 ° C, preferably 1100 ° C to 1 ° C.
It is preferable to perform the firing at 250 ° C. for a firing time of 1 to 8 hours.

In the sintering step, components other than the inorganic pigment in the transfer material and components such as the image receiving layer disposed on the surface of the ceramic body together with the image are evaporated or incinerated. Therefore, the materials (the components in the transfer layer and the components in the image receiving layer) disposed on the surface of the ceramic body together with the inorganic pigment during the sintering step contain atoms or compounds that are not lost by evaporation or combustion in the sintering step. It is preferable not to contain an atom or a compound which changes color by reacting with an inorganic pigment.

The ceramic body with a picture produced by the manufacturing method of the present invention can be used, for example, in a ceramic photo application (portrait, funeral photograph, pet photograph, etc.) by selecting various shapes and formed images of the ceramic body to be painted. , For commemorative photos you want to keep forever, amusement and accessories (mugs, liquor bottles,
Building crests, including fish crests, fish cultivation, etc., and building materials (art tiles used on walls of bathrooms, entrances, living rooms, lobbies, guest rooms, etc., signs, information boards, room accessories, interior goods, etc.)
And so on.
