Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form and a transfer method to the form, and in particular, to easily transfer magnetic information on a medium,
The present invention relates to a form that can be saved and a transfer method to such a form.

[0002]

2. Description of the Related Art As a transfer (copy) sheet, carbon paper has been used for a long time, and recently transfer paper to which a microcapsule technique called so-called carbonless paper is applied has been used.
These are ones in which carbon is transferred only to a pressed portion or microcapsules are destroyed by a pen pressure or a printing pressure of an impact printer or the like to cause a coloring reaction.

Incidentally, with the recent spread of credit cards, prepaid cards and the like, as one of card approval work, a predetermined information recorded on the card is transferred to a form using an imprinter. There is. For example, a credit card has a magnetic stripe and embossed character information provided in an area other than the magnetic stripe area. Then, by setting such a credit card and a form made of carbonless paper on the imprinter in a state of being overlapped, and reciprocating the roller of the imprinter, the difference in pressure difference due to the unevenness of the embossed character part is used. The embossed character information is transferred to the form.

[0004]

However, in the conventional credit card, the amount of character information by embossing is small, the content of the character information can be easily read by a third party, and the thickness of the card increases by embossing. There are problems such as being bulky when holding multiple cards,
There is a request to add information to the card by means other than embossing. In response to such a demand, for example, a card in which magnetized characters and numbers are formed by printing using magnetic ink has been developed. However, since there is no pressure difference between the information part and the non-information part on the card, there is a problem that the information cannot be transferred in the form using the conventional carbon paper or carbonless paper.

The present invention has been made in view of the above circumstances, and a form capable of reliably and easily transferring and storing information on an information medium provided with magnetic information and having no surface irregularity, and to such a form It is an object of the present invention to provide a transfer method for

[0006]

In order to achieve such an object, the form of the present invention comprises a transfer sheet in which a thin film holds a magnetic toner and a volatile solvent at a predetermined position on one surface of a substrate, The fixing sheet is provided on the transfer sheet on the thin film side.

Further, in the method of transferring to a form of the present invention, pressure is applied from the form by a transfer roller in a state where the form is placed at a predetermined position on an information medium provided with magnetic information, The magnetic toner is fixed on the fixing sheet forming the form so as to correspond to the magnetic information.

[0008]

Function: Pressure is applied by the transfer roller so that the pressure is reciprocally different from the form placed on the form of the information medium provided with the magnetic information. At this time, the form is placed at the place on one side of the base material. A transfer sheet that holds a magnetic toner and a volatile solvent by a thin film, and a fixing sheet that is stacked on the transfer sheet from the thin film side. Between the transfer sheet and the fixing sheet, in which the magnetic toner constitutes a form together with the solvent, the magnetic toner is movably positioned according to the magnetic information and moved in the volatile solvent according to the magnetic information.
It is fixed on the fixing sheet.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic sectional view showing an example of a form according to the present invention. In FIG. 1, the form 1 includes a magnetic toner 5 and a volatile solvent 6 formed by a thin film 4 on one end of the base material 3.
Holding the transfer sheet 2 and the thin film 4 of the developing sheet 2
It is composed of a fixing sheet 7 which is stacked on the side.

As the base material 3, synthetic paper such as polystyrene, fine paper, art paper, coated paper, synthetic resin-impregnated paper, emulsion-impregnated paper, etc. can be used. Excellent synthetic paper and surface coated paper are preferred. Further, the base material 3 preferably has a high magnetic permeability so that the magnetic toner can easily move according to magnetic information as described later.

The magnetic toner 5 is fine particles in which a magnetic material is dispersed in a binder.

As a magnetic material constituting the magnetic toner, F is
e ₃ O ₄ , γ-Fe ₂ O ₃ , Co deposited γ-Fe ₂ O ₃ ,
Fe-Cr, Fe-Co, Co-Ni, Ba ferrite, Sr _{ferrite, CrO 2, Fe 3 C,} Fe, Mn
Examples thereof include Al. The particle size of such a magnetic material is preferably about 0.1 to 2 μm.

Examples of the binder in which the above magnetic material is dispersed include wax resins such as microcrystalline wax, carnauba wax, paraffin wax, montan wax, casta wax, nitrile rubber, and styrene.
Butadiene rubber, acrylonitrile-butadiene rubber,
Examples thereof include rubber-based resins such as neoprene rubber, butyl rubber, isoprene rubber and natural rubber, urethane elastomers and the like. If necessary, butyral resin, vinyl chloride / vinyl acetate copolymer resin, urethane resin, polyester resin, cellulose resin, acrylic resin, styrene / maleic acid copolymer resin, etc. can be used.

If necessary, low molecular wax such as polypropylene and polyethylene, silica, titanium oxide, alumina, etc. may be added internally or externally to the magnetic toner 5 or on the surface of the magnetic toner 5.

Such a magnetic toner 5 has a particle size of 5
˜100 μm, preferably about 10-20 μm.
When the magnetic toner 5 is less than 5 μm, it is difficult to move the toner due to the surface roughness of the transfer sheet or the fixing sheet, and when it exceeds 100 μm, the resolution of the transferred image decreases, which is not preferable.

Examples of the volatile solvent 6 include aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, alcohols, ketones, esters, alcohol esters, ketone esters, ketone alcohols and ethers. Examples thereof include alcohols, ketone ethers, ester ethers, acetals, acids and furans. Specifically, examples of the highly volatile solvent include acetone, ethyl ether, tetrahydrofuran, ethyl acetate, and examples of the less volatile solvent include toluene, methanol, butyl acetate, xylene, butanol and the like. . In consideration of the ease of movement of the magnetic toner in the volatile solvent 6 and the fixability of the magnetic toner in the transfer step, which will be described later, it is preferable to select a single solvent or a mixed solvent in consideration of the volatilization rate.

Magnetic toner 5 and volatile solvent 6 as described above
The thin film 4 for holding can be formed of synthetic paper, coated paper, synthetic resin-impregnated paper, emulsion-impregnated paper, or the like. The thickness of such a thin film 4 is preferably about 50 to 200 μm, and has such a film strength that it can be destroyed by the pressure applied by a transfer roller described later.

As a place for holding the magnetic toner 5 and the volatile solvent 6 by the thin film 4 as described above, one end of the substrate is usually preferable. With this configuration, the transfer roller is moved from one end of the base material holding the magnetic toner 5 and the volatile solvent 6 to the other end, and the thin film 4 is destroyed and the magnetic toner 5 is removed. The contained volatile solvent 6 can be spread uniformly between the transfer sheet and the fixing sheet.

The magnetic toner 5 held by the thin film 4
Although the total amount of the volatile solvent 6 and the volatile solvent 6 can be appropriately set according to the area of the form 1, it is usually preferably about 0.2 to 2.0 cm ³ . The content of the magnetic toner 5 in the volatile solvent 6 is preferably about 0.1 to 10% by weight.

The fixing sheet 7 constituting the form 1 is for fixing the magnetic toner 5 gathered in a shape corresponding to magnetic information as described later. Such a fixing sheet 7
Can be appropriately selected from the materials that can form the base material 3.

Further, the form 1 of the present invention may have a pressure sensitive adhesive layer 8 on the fixing sheet 7 as shown in FIG. By providing the pressure-sensitive adhesive layer 8 in this manner, the magnetic toner 5 can be easily fixed on the fixing sheet 7 in the transfer to a form described later.

A known pressure-sensitive adhesive can be used as the pressure-sensitive adhesive layer 8, but a wax-based or rubber-based pressure-sensitive adhesive that reacts at a pressure equivalent to the fixing pressure of the magnetic toner in the transfer to a sheet described later. Adhesives are preferred. Specifically, natural rubber,
Examples thereof include esterified natural rubber, styrene-butadiene rubber, chloroprene rubber, polyvinyl acetate, polymethylmethacrylate, and the like, or a mixture thereof.

Next, taking the form 1 shown in FIG. 2 as an example,
A method of transferring magnetic information from an information medium provided with magnetic information to a form will be described with reference to FIG.

First, the form 1 is placed so that the fixing sheet 7 is in contact with the information medium 11 provided with the magnetic information 12 (FIG. 3 (A)). In the illustrated example, the holding area of the magnetic toner 5 and the volatile solvent 6 by the thin film 4 is placed at a position where it does not overlap the information medium 11. Next, while applying a predetermined pressure on the transfer sheet 2 of the form 1, a transfer roller (not shown) is moved in one direction, for example, from left to right in the figure, to press the form (outward pressurization). (FIG. 3 (B)). As a result, the thin film 4 is broken and the magnetic toner 5 flows out between the transfer sheet 2 and the fixing sheet 7 together with the volatile solvent 6,
The magnetic toner 5 can move in the volatile solvent 6 according to the magnetic information 12. Then, after the magnetic toner has moved in the volatile solvent according to the magnetic information, the transfer roller is moved in the opposite direction, for example, from the right to the left in the figure, and the form is pressed again (return pressurization). As a result, the magnetic toner 5 is fixed onto the pressure-sensitive adhesive layer 8 of the fixing sheet 7 in a state corresponding to the magnetic information 12 (FIG. 3C).

As described above, according to the method of transferring to the form of the present invention, the transfer roller is reciprocated once on the form by changing the pressure,
First, in the outward pressurization, pressure was applied to destroy the thin film and not to fix the magnetic toner, and the magnetic toner was moved in the volatile solvent according to the magnetic information and the volatile solvent was volatilized and removed. After that, the magnetic toner is fixed to the fixing sheet by applying pressure in the outward path. Further, if the moving speed of the transfer roller is taken into consideration so as to give a sufficient developing time, it is possible to apply the fixing pressure to the pressure of the transfer roller to perform the developing / fixing only in the outward path. Therefore,
For example, the imprinter at a conventional credit card store can be used as it is to transfer it to a form. Further, since heat and light energy are not used, energy is saved, the transfer device can be downsized, and high-speed transfer is possible, and since the transfer device does not require consumables, maintenance is easy.

The form of the present invention is not limited to the above-mentioned form, and may be, for example, one in which the above-mentioned form 1 is further stacked to form a multi-part form.

Next, the magnetic recording medium of the present invention will be described in more detail with reference to experimental examples. (Experimental Example) Preparation of Sample 1 As a base material, a coated paper having a thickness of 100 μm is formed as a thin film on one end of a synthetic paper (Yupo manufactured by Oji Yuka Synthetic Paper Co., Ltd.) having a size of 85 × 140 mm. A magnetic ink (1 cm ³ ) having the composition shown below was held to prepare a transfer sheet.

(Composition of magnetic ink) -Volatile solvent (ethanol) ... 100 parts by weight-Magnetic toner (PC-30 toner manufactured by Canon Inc., particle size 10 µm) ... 2 parts by weight Next, synthetic paper as a fixing sheet (Oji Yuka Synthetic Paper Co., Ltd.
YUPO) was stacked on the thin film formation side of the transfer sheet to prepare a form (Sample 1). Preparation of Sample 2 Form (Sample 2) was prepared in the same manner as Sample 1 except that a pressure-sensitive adhesive having the following composition was applied on the fixing sheet by a gravure method to form a pressure-sensitive adhesive layer (thickness 3 μm). It was created.

(Composition of pressure-sensitive adhesive) Styrene-butadiene rubber ... 30 parts by weight Water ... 60 parts by weight Microsilica ... 3 parts by weight For each form (samples 1 and 2) prepared as described above, The magnetic information on the information medium (magnetic card) was transferred under the following conditions.

(Magnetic card) Coercive force: 2750 Oe Residual magnetic flux density: 1.4 Mx / cm Recording density: 210 BPI (transfer condition) Using elastic roller Thin film breaking pressure: 80-100 kg
f / cm ² Fixing pressure: 200 to 300 kgf / cm ² As a result, the magnetic information provided by the magnetic ink on the information medium was satisfactorily transferred onto the fixing sheet of the form.
