Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card having a writing area available recordable capable of performing the entry by writing instruments, such as sign.
[0002]
Conventionally, as shown in FIG. 8, a conventional plastic card 20 such as a credit card or a cash card is generally written on a so-called sign panel or silk panel as an area for entering the name of the card user. In many cases, a writing panel 21 is provided, and an entry 22 is displayed on the writing panel 21 by writing.
Conventionally, of the writing panel 21, the sign panel has a sheet member for the sign panel pasted on a part of the area on the card base, and the silk panel is white on a part of the area on the card base. For example, it was provided by silk screen printing with the ink.
[0003]
However, when the above sign panel or silk panel is provided on the card substrate, in any case, a part of the card surface becomes convex, and the smoothness of the card surface is lost. For this reason, there is a problem with a direct type printer that directly prints on the surface of the card because there are limitations on the print area and there are negative aspects such as adverse effects on the thermal head.
[0004]
Furthermore, there is a problem that writing suitability is deteriorated for full-screen printing by retransfer, which will become the mainstream in the future, because ink and a retransfer layer are also placed on the panel.
Also, because part of the surface of the card is convex, there is a danger that the sign panel and silk panel will gradually disappear from the card base material by rubbing this convex part or catching on other objects. There is also a problem.
[0005]
[Problems to be solved by the invention]
The present invention for solving the above problems, without the smoothness of the card surface is lost, the card having a writing area available recordable causing no step between the writing area and the other area provide.
[0006]
[Means for Solving the Problems]
Cards having additionally recordable writing region of the present invention, in a card having a writing area that can be filled in by writing instrument, the card includes a printed layer and a transparent protective layer on a card substrate made of a white color in this order a laminated ing with cards that, by Rukoto provided the printing layer only in the region excluding the region corresponding to the writing area, to form a writing area in a state in which visible white solid on the card surface It is characterized by.

FIG. 7 is a perspective view showing a state in which a protective sheet is pasted on a writing area of a card having a writable writing area according to the present invention, and FIG. 8 is a card having a conventional writing panel. FIG.
[0010]
As shown in FIGS. 1 and 2, the card 1 having a writable writing area of the present invention has only an area portion that becomes a writable writing area 3 on at least one surface of the card base 2. A printed layer 4 made of a pattern or the like is formed on the other areas except for the above, and a transparent protective layer 5 is laminated on the printed layer 4 and the writable writing area 3 where the printed layer 4 is not provided. ing.
Further, the card substrate 2 and the print layer 4 are bonded by an adhesive layer 6.
Then, by writing and displaying the entry 7 in the writing area 3 that can be additionally written, the lower surface side of the portion where the entry 7 is written is not printed, so the entry 7 can be clearly displayed. I can do it.
[0011]
The card substrate 2 is not particularly limited, and specifically, polyvinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer resin, butadiene resin, acrylonitrile-butadiene-styrene copolymer resin, Synthetic resins such as polycarbonate resin, polyamide resin, cellulose resin, polyolefin such as polyester, polyethylene, polypropylene, polyvinyl alcohol, acrylic resin, polymethyl methacrylate resin, styrene resin, urethane resin, fluororesin or mixtures thereof Can be mentioned.
[0012]
And it is especially preferable that this card base material is white, and when the card base material is white, when an entry such as a signature is made on the writable area 3 that can be additionally written, the entry items become clear. There is an effect that can be displayed.
However, the color is not necessarily limited to white, and may be any color that can read at least the entry in relation to the color of the writing instrument.
[0013]
The printed layer 4 and the transparent protective layer 5 formed on the card substrate are formed by a thermal transfer method using a thermal transfer sheet.
As shown in FIG. 3, the thermal transfer sheet used in the present invention has a structure in which a release layer 10, a transparent protective layer 5, a printing layer 4, and an adhesive layer 6 are sequentially laminated on a support sheet 9. Yes.
In the configuration of the thermal transfer sheet 8, the transparent protective layer 5 and the print layer 4 on the support sheet 9 are necessarily required. However, the release layer 10 and the adhesive layer 6 can be separated and formed without forming each layer. It can be omitted if it can be glued.
[0014]
The support sheet 9 is not particularly limited and may be a conventionally known sheet, as long as it has releasability from the transfer layer, and the surface to be transferred has unevenness, and further has shape followability to the unevenness.
Therefore, if the transfer surface is a flat or two-dimensional uneven surface, it is possible to use paper having no stretchability.
When the transfer surface is a three-dimensional uneven surface, a support sheet having stretchability is used at least during transfer.
[0015]
Examples of the stretchable support sheet include polypropylene, polyethylene, polymethylpentene, ethylene-propylene copolymer, ethylene-propylene-butene terpolymer, olefin resin such as olefin-based thermoplastic elastomer, polyethylene terephthalate, etc. A low-stretched or non-stretched resin film (sheet) made of a thermoplastic polyester resin such as polybutylene terephthalate, a vinyl chloride resin, a polyamide resin, or an elastomer such as a urethane-based thermoplastic elastomer is preferably used.
[0016]
Further, the support sheet may have a single-layer structure or a multilayer structure composed of different materials.
For example, when the transfer surface is flat, a support sheet having a structure in which polypropylene is laminated on high-quality paper is one of the preferable support sheets in terms of excellent transferability and low cost.
In addition, the thickness of a support body sheet | seat is about 20-200 micrometers normally.
[0017]
In addition, in order to improve the peelability from the transfer layer on the transfer layer side, the release layer 10 may be provided on the support sheet as a component of the support sheet, if necessary.
The release layer 10 is peeled and removed from the transfer layer as a part of the support sheet when the support sheet is peeled off.
As the release layer 10, 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.
[0018]
The transparent protective layer 5 is a layer for improving surface properties such as wear resistance and solvent resistance.
The transparent protective layer 5 uses, as its resin component, a two-component curable resin that crosslinks an acrylic polyol using a silane coupling agent as a crosslinking agent.
In general, an isocyanate compound can be used as a crosslinking agent for the acrylic polyol, but in the present invention, a silane coupling agent is used as a crosslinking agent without using an isocyanate compound.
Thereby, after laminating the thermal transfer sheet on the transfer target, the peeling force when peeling the support sheet is appropriate, and it is stabilized and constant without changing over time.
[0019]
There is no limitation in particular as said acrylic polyol, What is necessary is just to select and use it according to a use and a required physical property from conventionally well-known things.
Among the polyols, a transfer product excellent in surface properties and weather resistance can be obtained by using acrylic polyol.
In addition, acrylic polyol is, for example, (meth) acrylic acid, methyl (meth) acrylate, ethyl (meth) acrylate, (meth) acrylic acid-n-propyl, isopropyl (meth) acrylate, (meth) acrylic acid. 1 type or 2 types or more of (meth) acrylic acid alkyl ester such as n-butyl, (meth) acrylic acid isobutyl, (meth) acrylic acid octyl, (meth) acrylic acid-2-hydroxyethyl, (meta It is a polyol having a plurality of hydroxyl groups obtained by copolymerizing a hydroxyl group-containing acrylic monomer such as 2-hydroxypropyl acrylate, 2-hydroxy-3-phenoxypropyl (meth) acrylate, or the like. In addition, (meth) acrylic acid means acrylic acid or methacrylic acid.
[0020]
As the silane coupling agent, a known silane coupling agent having an amino group, a vinyl group, an epoxy group, a mercapto group, a chloro group or the like in addition to the alkoxy group may be used.
For example, γ-aminopropyltriethoxysilane, γ-methacryloxypropyltrimethoxysilane, γ-methacryloxypropylmethyldimethoxysilane, γ-methacryloxypropyldimethylmethoxysilane, γ-methacryloxypropyltriethoxysilane, γ-methacryloxy Propyldimethylethoxysilane, γ-acryloxypropyltrimethoxysilane, γ-acryloxypropylmethyldimethoxysilane, γ-acryloxypropyldimethylmethoxysilane, γ-acryloxypropyltriethoxysilane, γ-acryloxypropylmethyldiethoxysilane , Γ-acryloxypropyldimethylethoxysilane, vinyltriethoxysilane, γ-glycidoxypropyltrimethoxysilane, γ-mercaptopropyltrimethoxysila Etc.
In addition, the addition amount of the silane coupling agent as a crosslinking agent with respect to acrylic polyol is about 5 to 15 parts by weight of the silane coupling agent with respect to 100 parts by weight of the polyol.
[0021]
In addition, although a transparent protective layer may be comprised only with the two-component curable resin which consists of said acrylic polyol and a silane coupling agent, you may add various additives suitably as needed.
[0022]
For example, when a filler of metal oxide particles is added as an additive, the wear resistance can be greatly improved.
Examples of the metal oxide particles as the filler include metal oxides such as aluminum, titanium, silicon, zirconium, and magnesium.
Specifically, for example, alumina such as α-alumina.
Such metal oxide particles having an average particle diameter of 2 to 3 μm, a particle size distribution having a minimum value of 0.01 μm and a maximum value of 6 μm, for example, can provide good wear resistance. This is preferable.
[0023]
In addition, the shape of the metal oxide particles is spherical or nearly spherical, such as a spheroid, which has good coating suitability (no streaks, etc.), and when a thermal transfer sheet is molded, it is transparently protected during molding. It is preferable that the layer does not easily crack or break.
As the shape, other shapes such as scales and polygons may be used. Moreover, although the addition amount of a metal oxide particle changes with required physical properties, it is about 0.1-30 weight part with respect to 100 weight part of said 2 liquid curable resins.
[0024]
As additives other than the metal oxide particles, known additives such as fillers such as extender pigments, lubricants such as waxes, ultraviolet absorbers, light stabilizers, and colorants are appropriately used.
[0025]
The transparent protective layer may be formed by a known forming method such as a printing method such as gravure printing or silk screen printing, or a coating method such as gravure coating or roll coating.
Further, the thickness of the transparent protective layer may be appropriately determined according to the use, required physical properties and the like, and is usually provided with a thickness of about 1 to 100 μm.
[0026]
Moreover, the release layer 10 is suitably provided as needed.
The release layer is not particularly limited and may be formed by a conventionally known material and method.
For example, acrylic resins such as polymethyl (meth) acrylate, polybutyl (meth) acrylate, methyl (meth) acrylate-butyl (meth) acrylate copolymer, vinyl chloride-vinyl acetate copolymer, cellulose resin alone or a mixture thereof Is mentioned.
The release layer may be formed by a known formation method similar to the transparent protective layer described above.
Since the release layer is not intended for surface protection, it is preferable that the release layer has a small thickness, for example, about 0.1 to 4 μm. If it is too thick, the effect of the transparent protective layer underneath is reduced.
[0027]
The printing layer 4 is a layer in which a pattern or the like is formed by a forming method and material using conventionally known printing such as gravure printing, silk screen printing, and offset printing.
In this print layer 4, when the transparent protective layer 5 and the print layer 4 are transferred onto the card base material using the thermal transfer sheet 8, a region corresponding to a region where the writing region 3 that can be additionally written on the card base material is provided. Only the portion is provided with a region portion 11 where no print layer is provided.
Thereby, even when the transparent protective layer 5 and the printing layer 4 are transcribe | transferred on the card | curd base material using the thermal transfer sheet 8, the surface of the card | curd base material 2 can be visually observed from the outside.
The ink (or coating liquid) for forming the printing layer is composed of a vehicle composed of a binder and the like, a colorant such as a pigment and a dye, and various additives appropriately added thereto, as in the case of a general ink (or coating liquid).
[0028]
As the resin used for the binder, for example, an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a polyester resin, a cellulose resin, a polyurethane resin, or the like, or a mixture containing these is used.
Colorants include titanium white, carbon black, petal, yellow lead, ultramarine blue and other inorganic pigments, aniline black, quinacridone, isoindolinone, phthalocyanine blue and other organic pigments, titanium dioxide coated mica foil powder, etc. Pigments or other dyes are used.
[0029]
The adhesive layer 6 is a layer for transferring and adhering the transfer layer to the transfer target, and a conventionally known thermoplastic resin, curable resin, or the like may be used.
For example, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer, acrylic resin, thermoplastic polyester resin, polyamide resin, ionomer, thermoplastic resin such as chlorinated polyolefin, phenol resin, block isocyanate curable urethane resin, etc. A thermosetting resin or the like is used as one or a mixture of two or more.
[0030]
The adhesive layer 6 may be formed by using a known printing method (or coating method) such as gravure printing (or roll coating) with the ink (or coating liquid) made of the above resin.
Although there is no restriction | limiting in particular in the thickness of the adhesive bond layer 6, Usually, it is about 1-100 micrometers.
Note that the adhesive layer can be omitted when the binder resin itself has sufficient adhesion to the transfer target and is formed on the entire surface.
[0031]
Next, the manufacturing method of the card | curd which has the writable area | region which can be additionally written of this invention is demonstrated based on FIG. 3 thru | or FIG.
First, as shown in FIG. 3, a thermal transfer sheet 8 having a printing layer 4 provided in advance with a writing area left on the transparent protective layer 5 is prepared.
Then, the adhesive layer 6 side of the thermal transfer sheet 8 is overlaid on the surface of the card base 2 as shown in FIG.
[0032]
Next, as shown in FIG. 5, after applying heat pressure from above the support sheet 9 of the thermal transfer sheet 8, the support sheet 9 is removed from the transparent protective layer 5 by the release agent layer 10 as shown in FIG. It peels and the printing layer 4 and the transparent protective layer 5 are laminated | stacked on the card | curd base material 2. FIG.
[0033]
As shown in FIG. 1, the card 1 having the writable writing area thus produced is printed from the outside in the transfer area corresponding to the area where the print layer 4 of the thermal transfer sheet 8 is not formed. It is formed in a state in which a white solid color on the surface of the card base that is not present is visible.
Therefore, by writing the card user's signature etc. as additional information on the transparent protective layer in the area where the printed layer on the card base is not provided, for example, the entry items are clearly displayed. be able to.
Further, as shown in FIG. 7, it is preferable to attach a tamper-proof seal 12 as necessary to prevent falsification of the entry.
[0034]
【The invention's effect】
