TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording material and a label printer cassette, and more particularly to a recording material and a label printer cassette capable of forming images such as transferable characters and figures.
[0002]
[Prior art]
Conventionally, decalcomania (decal) for transferring an image formed on a film to a surface of glass, plastic, or the like, instant lettering, and the like have been performed.
As a decal, for example, there is a decal using a water transfer decal such as a decoration seal of a plastic model. In this decal, a water-soluble adhesive is applied to the back surface of a water-insoluble synthetic resin film (eg, a polyethylene film) on which an image is printed, and the adhesive applied surface is bonded to a substrate on which a release layer is formed. Used recording material. The decal by the recording material is performed by attaching a synthetic resin film which has been separated from the base material by water and floated on water to a predetermined position, dried and fixed.
Since it is necessary to move the decal floating in water to a predetermined position, there is a problem that it is difficult to accurately decal to a desired position.
In the instant lettering, a recording material having a release layer, a character (pattern) layer, and a pressure-sensitive adhesive layer formed on a substrate in this order is used, and the pressure-sensitive adhesive layer is closely adhered to a transferred material and strongly rubbed. In this way, the transfer to the transfer target is performed by the pressure-sensitive transfer layer. At this time, it is difficult to apply a certain pressure or more only to the characters and pattern portions, and there is a problem that the peripheral pressure-sensitive adhesive layer transferred along with those portions is conspicuous and impairs the appearance of the transferred material. .
In addition, both conventional decals and instant lettering are firmly adhered to the transfer object, and it is very difficult to remove them later.
[0003]
Recently, a label printer capable of forming an arbitrary character or pattern on a long recording material has attracted attention. Decal or instant lettering differs from label printers in that it transfers only ready-made characters and patterns. In a label printer, a character or a pattern is formed on a recording surface of a recording material for a label printer by thermal transfer or the like, and can be attached to a desired position of an object by an adhesive layer on the opposite side of the recording surface. In this case, since the recording material itself is stuck instead of the transfer, there is a problem that the recording material becomes an obstacle.
Further, recording materials for creating instant lettering in which arbitrary characters and patterns can be formed by a label printer have been released, but the above-mentioned problem has not been solved.
[0004]

The present invention has been made in view of the above problems, and can easily and satisfactorily transfer an image of a desired character, figure, or the like onto an object to be transferred, and can easily remove the transferred image. The purpose is to provide a simple recording material.
Further, the present invention provides a recording material that can easily and satisfactorily transfer an image of a desired character, graphic, or the like onto an object by using a label printer, and that can easily remove the transferred image. The purpose is to:
[0005]
[Means for Solving the Problems]
The present invention for achieving the above object, a recording material comprising a base material and a transfer layer for forming a transfer image laminated on one surface of the base material, wherein the base material is water-permeable, The transfer layer is a water-soluble thermoplastic resin, and is thermally fused to the base material.
Further, the present invention is a recording material comprising a long base material and a transfer layer for forming a transfer image laminated on one surface of the base material, wherein the base material is water-permeable, The recording material for a label printer, wherein the transfer layer is a water-soluble thermoplastic resin and is thermally fused to the base material.
Further, the present invention has a recording material supply means on which the recording material for a label printer is wound, a print medium supply means on which a print medium is wound, and a print medium winding means for winding a print medium after printing. This is a label printer cassette.
[0006]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The base material of the recording material of the present invention may be any material having water permeability, such as natural fibers such as manila hemp, mulberry, mitsumata and pulp, and one or two types of synthetic fibers such as polyester, vinylon, nylon and rayon. A paper made by wet or dry method using a combination of seeds or more, or a screen printing gauze made of polyester, nylon or the like can be used.
To ensure that the transfer layer is peeled off from the base material, and to prevent the transfer layer from adhering to the back surface of the base material when stored in a stacked state, a porous material such as silicon resin is formed on the base material. Can be formed.
[0007]
The transfer layer of the recording material of the present invention is made of a water-soluble resin having heat melting property. Examples of the water-soluble resin having a heat melting property that can be used as the transfer layer include polyvinyl alcohol, polyvinylpyrrolidone, acrylamide-acrylate copolymer, acrylamide-acrylate-methacrylate copolymer, and styrene-anhydride. Known resins such as a maleic acid copolymer alkali salt and polyacrylamide can be exemplified.
[0008]
The thickness of the transfer layer is preferably from 10 to 30 μm. When the thickness of the transfer layer is less than 10 μm, the transfer layer is easily broken during image formation. In particular, when an image is formed on a thermal transfer medium, the transfer layer is likely to be damaged. On the other hand, when the transfer layer is thicker than 30 μm, the transfer layer becomes conspicuous, and the quality of the transferred image is impaired.
[0009]
The transfer layer may contain a pigment, a dye, and the like, and further, if necessary, an ultraviolet absorber, organic and / or inorganic fine particles, a release agent, a plasticizer, a dispersant, an infrared absorber, and an antistatic agent. , An antifoaming agent, a leveling agent, and the like.
[0010]
The method for forming images such as characters and figures on the transfer layer is not particularly limited, and a conventionally known method can be used. For example, a method of forming arbitrary characters and patterns with a writing instrument such as a magic pen and a pencil, and a method of forming characters and patterns with a word processor and a label printer can be used. In particular, it is preferable to form an image using a word processor or a label printer capable of mirror image printing. This is because characters and patterns formed on the transfer layer are transferred as mirror images on the transfer target.
In the case of a recording material for a label printer, it is preferable to use a heat-fusible or sublimation type transfer medium as a transfer medium for forming an image on a transfer layer. In particular, it is preferable to use a transfer medium having a low heat melting temperature or sublimation temperature, for example, a wax type transfer medium having a low transfer temperature. This is because when a character or a pattern is formed using a transfer medium having a high heat melting temperature or a high sublimation temperature, the heat causes the transfer layer to excessively adhere to the substrate.
[0011]
The recording material of the present invention can be manufactured as follows. A film having a predetermined thickness is formed by using the water-soluble resin having the above-mentioned heat melting property. The film is superimposed on the substrate and heated to bond them. The heating temperature for bonding the substrate and the film is from the softening point to the melting point of the film. If it is below the softening point, the film will not adhere to the substrate, and if it is above the melting point, it will be difficult for the film to peel off from the substrate.
[0012]
As described above, the recording material of the present invention can be produced by superposing a water-soluble resin film on a substrate and heating the substrate. That is, since a troublesome process such as application of an adhesive is not required, it can be manufactured extremely easily and at low cost.
[0013]
Further, a water-soluble surface layer may be formed on the transfer layer. When a surface layer is formed on the transfer layer, characters and patterns to be transferred are formed on the surface layer. When forming a character or pattern using a heat-fusible or sublimation transfer medium, the heat transferred to the interface between the transfer layer and the base material is reduced, so that the transfer layer is heated by the heat when forming the character or pattern. It does not adhere excessively to and cannot be separated. Therefore, in this case, a transfer medium having a high melting temperature or high sublimation temperature can be used. Further, it can be suitably used also when forming a color image which needs to be transferred a plurality of times.
[0014]
The above-mentioned surface layer turns on various conventionally known devices such as various blade coaters, roll coaters, air knife coaters, bar coaters, rod coaters, gate roll coaters, curtain coaters, short dwell coaters, gravure coaters, flexographic gravure coaters, and size presses. Coating can be performed using a machine or an off-machine. Further, after coating, finishing may be performed using a calendar such as a machine calendar, a TG calendar, a super calendar, and a soft calendar. The thickness of the surface layer is preferably 3 μm to 35 μm. If it is less than 3 μm, the heat applied to the transfer layer cannot be sufficiently reduced. This is because if the thickness is more than 35 μm, the aesthetic appearance of the image transferred to the transfer object is impaired.
[0015]
Examples of the surface layer include a layer containing a water-soluble polymer. Examples of the water-soluble polymer include polyvinyl alcohol, starch or a dielectric material thereof, hydroxyethyl cellulose, carboxymethyl cellulose, methyl cellulose, cellulose derivatives such as ethyl cellulose, sodium polyacrylate, polyvinyl pyrrolidone, acrylamide-acrylate copolymer, acrylamide-acryl. Conventionally known water-soluble polymers such as acid ester-methacrylic acid copolymer, styrene-maleic anhydride copolymer alkali salt, polyacrylamide, sodium alginate, gelatin, casein and the like can be used without any particular limitation. The surface layer may also contain a colorant such as a pigment or a dye, similarly to the transfer layer. Further, if necessary, it may contain an ultraviolet absorber, organic and / or inorganic fine particles, a release agent, a plasticizer, a dispersant, an infrared absorber, an antistatic agent, an antifoaming agent, a leveling agent, and the like. .
[0016]
FIG. 1 is a partially cutaway view showing an example of the cassette according to the present invention. The cassette A includes a recording material supply unit 3 on which the long recording material is wound, and a printing medium supply on which a printing medium 6 for forming characters and patterns on a transfer layer or a surface layer of the recording material 5 is wound. A printing medium winding means for winding the printing medium after printing.
[0017]
The recording material 5 wound around the recording material supply means 3 is once exposed to the outside of the case via the guide 4 at the openings 10 formed in the cases 1 and 2. On the other hand, the print medium 6 is unwound from the print medium supply means 8 and is stacked so that the printable surface at the opening 10 is in contact with the transfer layer or surface layer of the recording material 5.
[0018]
The opening 10 is formed at a position corresponding to the positions of the thermal head B1 and the platen roller B2 of a label printer (not shown). In the opening, the thermal head B1 and the platen roller B2 sandwich the printing medium 6 and the recording material 5, and desired characters and patterns are formed on the transfer layer or the surface layer of the recording material 5.
After printing, the print medium 6 is taken up by the print medium take-up means 7, and the recording material 5 is taken out of the cassette A via the guide 9.
Hereinafter, the present invention will be described more specifically with reference to examples.

[Example 1]
Production of recording material A 20 μm thick water-soluble hot-melt resin film (PAOGEN PP-15; melting point: 55 ° C., manufactured by Daiichi Kogyo Seiyaku) is superimposed on a 40 μm thick porous thin paper. Then, an iron heated at 150 ° C. was pressed against the back surface of the tissue paper (the surface not in contact with the resin film) for 2 seconds, and the resin film was fused to the porous tissue paper to obtain a recording material of the present invention.
[0020]
Formation as recording material for label printer In the same manner as described above, a recording material having a length of 3 m was obtained, and the recording material was slit into widths of 18 mm and 46 mm.
A recording material slit to a width of 18 mm was mounted on a label printer cassette (XR-18BU, manufactured by Casio) having a heat-fusible transfer medium to obtain a label printer cassette (1) of the present invention.
Further, a recording material slit to a width of 46 mm was mounted on a label printer cassette (XR-46, manufactured by Casio) having a full-color sublimation transfer medium to obtain a label printer cassette (2) of the present invention. At this time, a black streak similar to the recording material used in the label printer cassette was formed on the back surface of the recording material.
[0021]
Forming and Transferring Characters and Patterns Using a Label Printer i) In the case of using a heat-fusible transfer medium The record of the present invention mounted on a label printer cassette (1) by a label printer (KL-8000, manufactured by Casio) On the transfer layer of the material, a monochromatic mirror image character and a mirror image pattern were formed. The formed characters and patterns were visually confirmed, and all were clear.
Cut the recording material for each character and pattern formed, place the transfer layer downward on each of the glass plate, acrylic plate and thumb nails to be transferred, and use a tissue paper soaked with water Pressed from above. Then, when only the base material was peeled off from the transferred material, only the transfer layer remained on each transferred material, and characters and patterns could be clearly distinguished on each transferred material.
Further, each was dried, and the state was visually confirmed. As a result, the characters and patterns were clear, and the boundaries between the transfer layers were unclear.
[0022]
ii) In the case of using a sublimation-type transfer medium A full-color sublimation-type transfer medium is formed on a transfer layer of the recording material of the present invention mounted on a label printer cassette (2) by a label printer (GC-100, manufactured by Casio). An image was formed. When the formed image was visually confirmed, it was clear.
The formed image was cut for each image, and the transfer layer was placed down on each of the glass plate and the acrylic plate to be transferred, and pressed with tissue paper containing water. Next, when only the base material was peeled off from the material to be transferred, only the transfer layer remained on each material to be transferred, and characters and patterns could be clearly distinguished on each material to be transferred.
Further, each was dried, and the state was visually confirmed. As a result, the full-color image was clear and the boundary portion of the transfer layer was unclear.
[0023]
Removal of transfer layer and image The transfer layer transferred as described above was rubbed with a tissue paper soaked in water, and all were easily removed.
[0024]
[Example 2]
On one surface of the resin film produced in the same manner as in Example 1, a solution having the following composition was applied at a solid content of 0.1 g / m ² and dried to form a surface layer.
Water-soluble cellulose resin (ST-102, manufactured by Washin Chemical Co., Ltd.): 40 wt. %
Methyl ethyl ketone: 60 wt. %
Then, the film was laminated on a surface of the film where the surface layer was not formed, in contact with a porous thin paper having a thickness of 40 μm, and then heated to 150 ° C. on the surface of the thin paper where the resin film was not in contact. The iron was pressed for 2 seconds. As a result, the resin film was fused to the porous thin paper, and the recording material of the present invention was obtained.
Using the recording material obtained above, formation as a recording material for a label printer, formation and transfer of characters and patterns using a label printer, and removal of a transfer layer and an image were performed in the same manner as in Example 1. However, all the results were as good as in Example 1.
[0025]
【The invention's effect】
The transfer layer of the recording material of the present invention becomes glue-like by a small amount of water from the back surface of the water-permeable base material, and is provided with tackiness. Therefore, images such as characters and figures formed on the transfer layer can be easily and accurately transferred to predetermined positions.
Further, since the transfer layer transferred together with the image is glued and adheres to the transfer target, the transfer layer is not conspicuous, and the image after drying can be kept in a beautiful state. Then, the transferred image can be easily and reliably removed even by washing with water.
Furthermore, when the transfer agent of the present invention is used as a recording material for a label printer, an image such as an arbitrary character or figure can be formed on the transfer layer, and a good transfer image can be obtained.
