Problems to be Solved by the Invention In recent years, more sophisticated and complicated print patterns have been required for flooring materials as the building has become more sophisticated. However, in the conventional method such as gravure printing, when the design is complicated and a multicolor pattern of four or more colors is generated, the pattern shift occurs at the time of printing, which makes it difficult to print. It is impossible to print. In addition, clothing stores, beauty salons, and other stores that require high fashionability have a desire to have their own original design for interior decoration according to fashion, but the floor space of such stores is Due to the small scale of less than about 100 m ² ,
Even when producing flooring materials with original designs, gravure roll plates, screen roll plates, etc. must be created and printed each time, and the resulting synthetic resin tiles will be very expensive. There's a problem. The present inventor has developed a new technique for solving the problems of the conventional techniques as described above and applied for a patent (see Japanese Patent Application No. 3-188285). However, the above-mentioned synthetic resin tile developed by the present inventor has a planar design, and there is a complaint that the three-dimensional effect and depth of the design are poor.

The base material layer 3 may be a layer containing a base cloth 5 having good dimensional stability such as glass fiber.

The full-color copying machine used in the present invention means a full-color copying machine which is usually commercially available by an electronic printing method, an electrostatic printing method or the like. In addition to normal copying, these full-color copying machines can also perform computer processing of external images from personal computers, video cameras, VCRs, etc. and connect them to the full-color copying machine to output (print). For example, an image designed by computer graphics can be input to a computer and output (printed) by a color copying device, or an image from a video camera can be input to the computer and output (printed) by a color copying device. It is possible to print various patterns in small quantities and in various types.

Intermediate pattern layer 2 for providing the above color image
Comprises a synthetic resin layer 2-1, a pearlescent layer 2-2 formed on the surface thereof, and a color image 2-3 formed on the surface of the layer by a full-color copying apparatus. Synthetic resin layer 2-
The material constituting No. 1 must be one that can be printed by a full-color copying machine, and because synthetic resin tiles are usually used as floor coverings,
It should not be easily peeled off from the surface or middle layer of the tile. Usually, in full-color copying, it is most preferable to copy on plain paper due to the adhesion of ink and toner, but when full-color copied plain paper is used as the intermediate pattern layer of the present invention, the formed synthetic resin tile is However, layer peeling and layer peeling easily occur from this plain paper layer, which is not preferable. Therefore, it is necessary to use a material that does not easily cause such layer peeling. Preferred examples of such a material include various synthetic resin films, sheets or synthetic papers. ℃ ~ 2
Due to the heat of 00 ° C., it is difficult to use a film, sheet or synthetic paper which shrinks or melts at this temperature. Therefore, it is preferable to use a film, sheet or synthetic paper made of a synthetic resin having a melting point of 200 ° C. or higher.

In the present invention, the pearl luster layer 2 described later is also used.
-2, the color image formed by the full-color copying machine expresses various color tones on the surface of the pearly luster layer with four colors of cyan, magenta, yellow, and black. Therefore, also in the present invention. In order to fully exhibit the function of the pearlescent layer, the above-mentioned film, sheet or synthetic paper is preferably white. Polyethylene terephthalate, which satisfies these conditions,
Polyester resins such as polybutylene terephthalate and polyamide resins such as nylon 6,66 nylon and the like having a melting point of 200 ° C. or higher and white films or sheets or synthetic papers can be preferably used in the present invention. The thickness of these films, sheets or synthetic papers is required to be a thickness capable of being copied and output by a full-color copying machine, and usually a thickness of 50 to 150 μm is preferable. In particular, when synthetic paper is used as a material for the intermediate pattern layer, heat resistance of 180 to 200 ° C. or higher is required similarly to the film. For example, synthetic paper made of resin having a melting point of 200 ° C. or higher such as polyester or polyamide is used. Used. Also, the specific gravity of the above-mentioned film, sheet or synthetic paper is 0.7 or more without delamination, and is suitable for the base material of the intermediate pattern layer of the synthetic resin tile of the present invention.

The pearlescent layer 2-2 formed on the surface of the synthetic resin layer 2-1 is formed by applying and drying an ink or paint containing a pearlescent pigment. A pearlescent pigment is a pigment particle having a size of about 5 to 150 μm, a plate-like shape, and a transparent crystal structure, and these plate-like particles have a layered structure in a vehicle. Is reflected in multiple layers, and known pearlescent pigments such as mica titanium and mica titanium are used. Although these pearlescent pigments are usually colored and used, they may be uncolored. Inks or paints containing pearlescent pigments are pearlescent pigments and resin binders having a softening point of preferably 70 ° C. or higher, such as acrylic acid ester, polyester, polyurethane (particularly preferably saturated polyester resin binders having a melting point of 70 ° C. or higher). ) And a solvent, and the pearlescent pigment is usually used in a proportion of 0.5 to 30% by weight. The synthetic resin layer 2-1 has a pearlescent layer 2-
As a method for forming 2, coating is performed by a general coating method such as a gravure roll so that the coating amount at the time of drying is about 3 to 30 μm, the coating is dried, and if necessary, a curing treatment is performed.

The transparent synthetic resin surface layer 1 is provided for the purpose of protecting the ink or toner of the intermediate pattern layer 2 and for providing the depth and gloss of the printed pattern and is transparent. There is no particular limitation as long as it is, but since the tile surface is required to have abrasion resistance, a polyvinyl chloride resin, ethylene-vinyl acetate copolymer sheet or film is laminated, or a curable liquid such as urethane is used. A resin may be applied on the intermediate pattern layer, or these curable liquid resins may be applied on the polyvinyl chloride resin sheet or film and cured to form the surface layer, but the present invention is not limited to these. Not a thing. The thickness of the surface layer 1 is required to be 0.05 mm or more, preferably 0.1 mm or more for abrasion resistance and protection of the intermediate pattern layer.

When a sheet or film made of polyvinyl chloride resin or the like is laminated as the surface layer, the above-mentioned synthetic resin surface layer and intermediate pattern layer are laminated with an adhesive in order to strengthen the peel strength between the layers. It is preferable to carry out the lamination through. When laminating with an adhesive, it is necessary to prevent bubbles from entering between the layers during lamination, and it is preferable to use a dry laminating method or a hot-melt adhesive for adhering after solvent or water of the adhesive is sufficiently vaporized. .. Further, as the material for the backing base material layer 3, known materials which are usually used for synthetic resin tiles can be used. For example, polyvinyl chloride resin sheet, ethylene-
Vinyl acetate copolymer, ethylene-copolymer resin sheet such as ethylene-ethyl acrylate copolymer, thermoplastic resin sheet such as olefin resin sheet such as polyethylene and polybutene, and dimensional stability of tiles on these sheets It is also possible to stack the base cloth 5 of glass fiber, polyester fiber, hemp, or the like, or to stack a balancing sheet for preventing warping of tiles. Further, these sheets 3 can be made of foam such as polyvinyl chloride resin or urethane.

The thickness of the backing base material layer 3 varies depending on the type of tile, and in the case of a so-called laying method in which tiles are attached to the floor surface without using an adhesive,
It is necessary to increase the weight of the tile to some extent, the total thickness of the tile is preferably 0.2 mm or more, and the thickness of the backing base material layer 3 is preferably 1.5 mm or more. When applying an adhesive at the time of tile installation and pasting it on the floor surface, the total thickness of the tile may be 2.0 mm or less,
Therefore, the thickness of the backing base material layer may be 1.5 mm or less, but is preferably 0.5 mm or more in view of the physical properties of the tile. The backing base material layer 3 and the intermediate pattern layer 2 may be laminated by using an adhesive, or the sheet of the backing base material layer may be heat-softened and welded. In the case of laminating via an adhesive, it is preferable that the surface layer 1 and the intermediate pattern layer 2 are bonded by a dry laminating method or a hot melt method as in the case of bonding. The method for manufacturing the synthetic resin tile of the present invention described above is not limited to the above method, and any other manufacturing method may be used.

Example 1 On a surface of A3 size polyester synthetic paper (thickness 100 μm, manufactured by Toyobo), a coating containing a saturated polyester resin containing 5% by weight of a pearlescent pigment as a main component, and a thickness after drying was 10 μm. Coating, drying and curing so that
A pearlescent layer was formed. The color-designed original image was placed on a copy table, and the desired pattern was copied on the surface of the pearlescent layer of the polyester synthetic paper. Next, a solvent-based polyester adhesive having a solid content of 30% by weight was applied at 100 g / m ² to a polyvinyl chloride backing base sheet laminated to a thickness of 1.2 mm, and the solvent was volatilized, The surface of the above-mentioned synthetic paper which was not printed was heated and laminated at 160 ° C by a dry laminating method. An aqueous polyester adhesive having a solid content of 30% by weight was applied at 80 g / m ² on a synthetic paper printing surface laminated on a backing substrate,
Evaporate the moisture, dry-laminate it with a 0.4 mm thick transparent polyvinyl chloride sheet, and bond it to synthetic paper.
It was cut into a size of 90 mm square to obtain a synthetic resin tile of the present invention.

Example 2 An image produced by computer graphic was measured in a size of 305 mm in length and width on the surface of which a pearly luster layer having a thickness of 8 μm, which contains a pearlescent pigment and a saturated polyester resin having a softening point of 115 ° C. as main components is provided. Then, color printing was performed by a color copying device on the surface of the pearlescent layer of a white polyester film having a thickness of 100 μm. Next, a solvent type urethane adhesive having a solid content of 30% by weight was applied at a rate of 80 g / m ² on the surface of a polyvinyl chloride resin backing sheet having a thickness of 2.5 mm in which glass fibers were laminated as an intermediate layer. The solvent was volatilized and heated to 160 ° C., and adhesively laminated with the surface of the above white polyester film which was not printed in full color. A transparent polyvinyl chloride paste having a thickness of 0.2 mm is applied to the surface of the intermediate pattern layer on which the backing base material layer is laminated, and gelled at 180 ° C. Further, an aqueous urethane treatment solution is applied to the surface of the intermediate pattern layer for 100 mm. It was dried at ° C and surface-treated. This was cut into a size of 300 mm in length and width to prepare a synthetic resin tile of the present invention having a vivid pattern created by computer graphics.

[0016]

[Effect] According to the present invention as described above, the following effects are exhibited. (1) It is possible to provide a synthetic resin tile having any pattern that cannot be produced by a conventional printing method such as a gravure printing method. (2) In the case of the conventional gravure printing method, textile printing, and screen printing method, it is necessary to create a plate roll for each new pattern, which is very expensive in a small number of productions. In the invention, there is no need to make a plate, so
It is possible to provide synthetic resin tiles of any design pattern easily and at low cost. (3) Even if the floor space is small, such as clothing stores such as boutiques and beauty shops where high fashionability is required and the original design unique to the store is required, the gravure roll plate should be used. It is not necessary to make it each time, and moreover, it is possible to easily and inexpensively provide the synthetic resin tile of the original design according to the user's preference. (4) Since the color image is formed on the surface of the pearlescent layer, the color image appears to be raised, and a synthetic resin tile having an extremely excellent three-dimensional effect and a deep design is provided. Such an effect is due to the fact that heat of 180 to 200 ° C. is applied at the time of copying a color image, the paint of the pearlescent layer is melted or softened, and a part of the color toner enters the pearlescent layer. Conceivable. Also, a large amount of toner is applied to the dark part of the image, and the pearlescent layer is lost, and conversely, the light and bright part of the image is applied with little toner or only a small amount of pearl. The gloss layer appears on the surface. In this way, the pearl luster becomes higher as the color of the image becomes lighter and brighter, and the pearl luster becomes lower as the color becomes darker and darker. In this way, the bright parts of the image appear bright and the dark parts appear to be sunk, so that the contrast of the image is enhanced, and the pattern has a three-dimensional effect and depth.
