Description

  The present invention relates to a method for forming a hand-drawn pattern or the like on an article such as ceramics, glass, tile, or basket, and a transfer paper used therefor.

  Conventionally, a method of directly drawing a pattern with a paint for decorating a pattern on a ceramic surface is widely known. When you try to make your own pattern or decorate by hand drawing, it is difficult to draw with a heavy base, especially drawing on curved shapes such as three-dimensional cups, vases, etc. There is a difficult point for amateurs because it is completely different from the drawing.

Transfer paper is also widely used for painting ceramics. FIG. 2 is a cross-sectional view showing a conventional transfer paper.
This conventional transfer paper A is composed of a pattern layer 10 printed with printing ink containing ceramic paint used in ceramics and the like, and a vinyl-based and cellulose-based overcoat layer 11 formed on the upper surface of the pattern layer 10. The film F is formed on the upper surface of the mount 13 through a water-soluble paste layer 12 such as starch paste.
This transfer paper A is produced by printing a pattern-printed positive film on a silk plate, printing the pattern on the surface of the paste layer 12 of the transfer paper by silk screen printing to form a pattern layer 10, and A synthetic resin is applied to the upper surface of the patterned layer 10.
The transfer paper is used by immersing the transfer paper in water, peeling the mount 13 from the film F, and further attaching the film F to the surface of the transfer object and baking it.
By this firing, the overcoat layer 11 evaporates and disappears, and the ceramic paint that is the main component of the pattern layer 10 is once melted and solidified at room temperature, and the pattern is drawn on the transfer object by the solidified ceramic paint.

On the other hand, the above-mentioned painting with the transfer paper makes it difficult to make a free design because the design is already drawn.
JP 60-83881 Japanese Patent Application Laid-Open No. 2002-68863 discloses a transfer paper that can be expressed by hand drawing. Japanese Patent Application Laid-Open No. 60-83881 applies a water-soluble paste to a water-absorbing mount, forms a peelable water-resistant resin film on this layer, and uses a technique such as hand-drawing, spraying, or stamping on the film. A transfer paper that has been colored and provided with a resin protective coating is shown.

  In recent years, an increasing number of people want to paint pottery in the city due to the spread of ceramics culture. In this case, the product is completed by firing the drawn material, but the pottery classroom in the city is often located away from the firing kiln, and there is a problem of transporting heavy objects and works on the way There is a risk of damage. Conventional hand-drawn transfer paper is coated with a protective film so that the image is not destroyed when the hand-drawn image is peeled off in water, but a separate coating facility is required, and the drawing operation is not completed in the classroom. In addition, it is not desirable to use organic solvents in the paint for working in the city. Furthermore, when firing in the city, the kiln is often an electric furnace or a microwave furnace, unlike a gas furnace that uses flames, a synthetic resin. It is difficult to erase decomposition products.

  The present invention has been made to solve the above-mentioned problems, eliminates the protective film coating process to be completed in the classroom, uses a transfer paper that can be drawn with water-based paint, and is decorated with little odor during electric furnace or microwave baking. A method is provided.

A second step in which the article is peeled off from the mount in water and attached to the article, and the article is baked to burn off the synthetic resin layer and the synthetic resin binder of the colored paint to fix the coloring material on the article surface. It is a method for decorating ceramic products characterized by comprising a process.

  The invention of claim 5 comprises a first step of decorating the transfer paper of claim 1 with a coloring material in which a coloring material and a synthetic resin binder are dispersed in water, and a frit synthetic resin layer and a colored layer. A second step in which the transfer layer is peeled off from the mount in water and attached to the article, and the article is baked to burn off the synthetic resin layer and the synthetic resin binder of the colored paint to fix the coloring material to the article surface. It is a ceramic product manufactured by the third step.

  According to a sixth aspect of the present invention, there is provided a first step of printing a water-soluble or water-dispersible colorant on the transfer paper of the first aspect with an ink jet printer, and a transfer layer comprising a frit synthetic resin layer and a colored print layer. A second step in which the article is peeled off from the mount in water and attached to the article, and the article is baked to burn off the synthetic resin layer and the synthetic resin binder of the colored paint to fix the coloring material on the article surface. It is a ceramic product manufactured by a process.

The invention according to claim 7 is an ink for an ink jet printer used for ceramic products, and is an ink for an ink jet printer characterized by adding a phospholipid to a water dispersible colorant and performing a fine dispersion treatment.

  As shown in FIG. 1, the hand-drawn transfer paper of the present application comprises a water-absorbing mount 1, a water-soluble paste layer 2 formed on the surface of the mount, a synthetic resin layer 3 formed on the surface of the paste layer, and a synthetic resin layer. And a frit layer 4 formed on the surface.

  The water-absorbing mount 1 holds the transfer layer, is dipped in water and peeled off, and a conventional transfer paper mount can be used.

  The water-soluble glue layer 2 formed on the surface of the mount is a glue that peels off when immersed in water, and then has a role of adhering the transfer layer to the transfer object. As the water-soluble paste, conventional transfer paper pastes such as starch, dextrin, polyvinyl alcohol, polyvinyl pyrrolidone, gum arabic, and water-soluble acrylic resin can be used. The glue may be formed by one layer, or may be constituted by two layers, a slide layer that dissolves in water and peels off, and an adhesive layer that adheres the transfer layer.

  The synthetic resin layer 3 formed on the surface of the glue layer was formed on the outermost layer surface in order to protect the printing surface in the conventional transfer paper, but on the glue layer so that the operation can be completed only with the transfer paper. Provided. A pattern is drawn on the resin layer, and the drawn image is held during the transfer operation in water.

  The transfer paper of the present invention is characterized in that a frit surface 4 is further provided on the synthetic resin layer 3. The decorating method of claim 2 draws with paint on this transfer paper, but when an ordinary consumer draws like a pottery class in an urban area, it is healthier to use an organic solvent to thin the paint. In view of the environment, water-based paints are undesirable. On the other hand, the synthetic resin layer 3 is made of a hydrophobic material so that it does not break during the transfer operation in water. Even if the hydrophobic resin layer is drawn with water-based paint, the paint is bounced and does not become a picture. When the frit layer is on the surface, the surface becomes hydrophilic and can be drawn with water-based paint. Furthermore, the colorant used for the soot is mixed with frit so as to be easily melted during firing. If you write with a paint mixed with frit, the shading will be poor, but by transferring this frit to the drawing base in advance, the pigment of the colored paint will have no or a small amount of frit. Drawing with good elongation and good brush strokes is possible. Since the frit surface only needs to be on the surface of the synthetic resin layer, it may be an integrated layer in which the frit is mixed with the synthetic resin layer as shown in FIG. 2, but it is usually composed of two layers in which a frit layer is provided on the synthetic resin layer. Composed.

  It is necessary that the synthetic resin layer 3 formed on the surface of the adhesive layer supports the hand-drawn pattern so as not to collapse at the time of transfer, evaporates at the time of baking, and does not react with the pigment. In addition, water-based materials cannot be used because they are provided on water-soluble glue, and when a frit layer is subsequently applied on a synthetic resin layer, it is compatible with the frit layer forming material so as not to repel the frit layer. It is necessary to have.

  As such a synthetic resin layer material, acrylic acid ester resin, methacrylic acid ester resin, vinyl acetate resin, cellulose resin, polyvinyl alcohol resin and copolymer resins thereof are used, preferably vinyl acetate resin, cellulose resin Among them, a polyvinyl butyral resin is particularly preferable.

  The frit layer 4 is composed of a frit and a binder. As the frit, a frit used for ceramics such as ceramics, glass, tiles, and firewood is used. When baked, the melting point is lowered to give a smooth and glossy picture.

As the binder, squeegee oil used for transfer printing can be used. Preferably, a resin such as an acrylate ester, a methacrylic acid resin or a copolymer thereof can be used.

  The amount of addition in the frit layer is 2 to 20 parts by weight of squeegee oil (solid content) with respect to 10 parts by weight of the frit. Preferably, 5 parts by weight to 10 parts by weight of squeegee oil (in solid content) is used with respect to 10 parts by weight of the frit. If there is little frit, the paint will be repelled, and if it is too much, no layer will be formed. Further, the thickness of the frit layer is selected from 0.3 μ to 100 μ, preferably from 3 μ to 10 μ. If it is too thick, the picture will flow.

  The transfer paper having the above-described configuration can be produced by applying an aqueous paste to a non-size paper, curling it, and cutting it.

  To decorate ceramic products using the above-mentioned hand-drawn transfer paper, the designer can draw an arbitrary pattern on the transfer paper with a brush, brush, spray, airbrush, seal, inkjet printer, etc. using water-based paint. Then, transfer paper with a pattern is created (FIG. 3). The transfer paper is immersed in water to remove the mount, and the synthetic resin layer and the pattern layer held thereon are attached to the transfer object (FIG. 4). When the patterned transfer material is dried and then fired, the synthetic resin layer evaporates, the frit melts and the pigment is melted (FIG. 5) and can be decorated as designed.

  The aqueous paint used here is a pigment mixed with a binder and dispersed in water. As the pigment, a pigment used for ceramic transfer can be used. When the opaque pigment is reapplied, the color that has been overlaid will develop. The use of a transparent four-color separation pigment (YMCK) produces vivid colors and a favorable picture, but it can be used according to the designer's intention.

  When the binder disperses the pigment in water and is applied to the transfer paper and dried, the pigment is fixed to the frit layer and insoluble in water. As such a material, an emulsion such as a vinyl acetate resin, an acrylic resin, or a urethane resin is used, and a vinyl acetate copolymer resin or an acrylic resin is preferably used in that the pigment does not separate and precipitate even when stored. The binder is used in an amount of 1 to 20 parts by weight, preferably 5 to 10 parts by weight, based on 10 parts by weight of the pigment. After mixing the pigment and binder, add 5 parts by weight of water to make a paint. When drawing, draw with an appropriate amount of water.

  Drawing can also be performed using an inkjet printer. The transfer paper is used as the printing paper, and the ink can be used by diluting the paint. The four color paints may be diluted and filled into four color ink cartridges, or the respective colors may be mixed and filled into a six to eight color printer.

  Ink jet printers eject ink through nozzles, so the pigment particle size must be reduced. For this reason, the ink which does not clog a nozzle can be obtained by adding a phospholipid to the coloring pigment used for ink, and carrying out a fine dispersion process.

  Phospholipids include egg yolk lecithin, purified soybean lecithin, phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, dicetylphosphate, stearylamine, phosphatidylglycerol, phosphatidic acid, phosphatidylinositolamine, cardiolipin and other glycerophospholipids, sphingomyelin, ceramide phosphorylethanol Sphingophospholipids such as amines and ceramide phosphorylglycerols, or substances such as glycerophosphonolipids, sphingophosphonolipids and mixtures thereof can be used, and lecithins such as egg yolk lecithin and soybean lecithin are preferably used. Further, as an improvement of lecithin, hydrogenation, partial hydrolysis, enzyme treatment or the like may be performed. From the viewpoint of stability, it is also preferable to separately add a component having a negative charge such as dicetyl phosphate to the solution of the present invention.

  As the fine dispersion treatment, a fine emulsion is obtained by sonicating an aqueous dispersion obtained by adding a pigment to phospholipid and dissolving in water after heating. Alternatively, known methods for producing liposomes such as a thin film method, a surfactant removal method, an ultrasonic method, an ether injection method, a high-pressure jet emulsification method, an extrusion method, and a supercritical fluid method can be used.

In the case of monochrome, an inorganic metal salt aqueous solution can be used instead of the paint. Examples thereof include chlorides such as cobalt, copper, iron, cadmium, nickel, chromium and lead, and alkali salts such as nitrate, sulfate, acetate, vanadic acid and tungstic acid. A monochromatic image with gradation can be drawn by filling the aqueous solution of these inorganic metal salts into multicolor ink jet printer cartridges with different concentrations.
The printed inorganic metal salt becomes a metal oxide when fired, and melts into a frit to become a coloring material. By using an aqueous solution, unlike a pigment, the ink nozzles of an ink jet printer are not clogged and a high density color can be produced.

  If the inorganic metal salt aqueous solution is printed, it will dissolve in water during transfer and the image will flow. It can be protected by spraying or coating a water repellent or hydrophobic organic layer on the printed image. In order to process in one step, it is preferable to mix a resin component in the ink. Similar to the paint, an emulsion of vinyl acetate resin, acrylic resin, urethane resin, vinyl acetate copolymer resin or the like is used.

Prepare paper that is coated with polyvinyl butyral resin and coated with polyvinyl butyral resin.
10 parts by weight of frit (10 μ to 15 μ): 6 parts by weight of squeegee oil (35% to 40% methacrylic acid ester copolymer, 25% to 30% aromatic hydrocarbon, 20% to 30% solvent) in a stirrer And stir to make ink.
Transfer paper is created by printing on the paper with a fully automatic screen printer.

  Stir 5 parts by weight of a 4-color decomposition pigment for transfer paper (manufactured by Kanemizu) with 5 parts by weight of a vinyl acetate copolymer resin emulsion with a stirrer to obtain a paint. A light draft is drawn on the transfer paper with a pencil, and the paint is spread with an appropriate amount of water and appropriately drawn with a brush, a brush or the like. After putting the drawn transfer paper in water, confirm that the film slides freely on the mount, and then slide it on a mug or the like. Lightly extrude bubbles etc. by hand, dry at room temperature (about 12 hours), and then fire in a kiln at 750 ° C to 800 ° C.

  5 parts by weight of soybean lecithin and 5 parts by weight of a pigment for color separation (made of Kanemizu) for transfer paper are stirred with a stirrer and dissolved in warm water to obtain an aqueous dispersion. The aqueous dispersion was subjected to ultrasonic treatment for 30 minutes using a probe-type ultrasonic homogenizer (ULTRASONIC DISPURTOR UR-200P, Tommy Seiko) to obtain an ink fine dispersion treatment liquid. 5 parts by weight of a vinyl acetate copolymer resin emulsion is added to the finely dispersed ink, and each ink tank of a four-color inkjet printer is filled. The image data is processed and printed by the inkjet printer. After drying, place the drawn transfer paper in water and confirm that the film slides freely on the mount, then slide it on a mug or the like. Lightly extrude bubbles etc. by hand, dry at room temperature (about 12 hours), and then fire in a kiln at 750 ° C to 800 ° C.

  Make ink solutions by dissolving 1%, 0.1%, 0.01%, and 0.001% cobalt chloride in 1% aqueous solution of vinyl acetate copolymer resin emulsion, and fill each ink tank of a four-color inkjet printer. . The image data is subjected to monochrome gradation processing and printed by the ink jet printer. After drying, place the drawn transfer paper in water and confirm that the film slides freely on the mount, then slide it on a mug or the like. Lightly extrude bubbles etc. by hand, dry at room temperature (about 12 hours), and then fire in a kiln at 750 ° C to 800 ° C. A dye-like product drawn in Kuresu was created.

  3D designs such as cups and vases can be created on a two-dimensional plane. This is not only applied to tableware, but also applied to ceramic paintings, outdoor information boards, nameplates, bridges, tunnels and other nameplates, and monuments it can.
