- 2 BAC~ROUND OF THE IN~rENTION
The present invention relates to a heat-sensitive magnetlc transfer element and more particularly to a heat-sensitive magnetic transfer element which allows a thermal printer to prepare a printed magnetic image recognized by a magne-tic ink character reader The magnetic ink character reader (hereinafter referred to as MICR) can read and recognize the certain printed magnetic image, such as character, or mark, which is printed to bill, check, credit card, pass, traffic census card, or the like. A magne~ic head in the MICR
converts the variations of magnetic portions corresponding to various characters and marks into predetermined signals, and volt;ages are detected to recognize the characters and marks.
In that case, it is necessary that each of the charcters and marks to be read by the magnetic head has a certain shape, dimensions and allowable ranges of dimensions in addition to the certain magnetic signal levels. Therefore, the allowable ranges as to E13B type face employed in American Bank Association are defined in JIS C 6251 (Japanese Industrial Standard).
E13B type face defined in JIS C 6251 consists of 10 numbers (0 to 9) and 4 special marks. According to JIS C 6251~ a character height, a character width, a corner radius, allowable ranges of those and an allowable range of a void with respect to each character are described. In addition to E13B type face, CMC7 type face is well known as type face for MICR. CMC7 type face is formed by arranging 7 longitudinal bars with 2 kinds of intervals, and each of CMC7 type faces can be magnetically recognized by combinations of 2 kinds of intervals. Thus, CMC7 type faces consist of 10 numbers, 26 large alphabets and 5 special marks, and dimensions and magnetic property of CMC7 type face are determined by European Computer Manufactures Association.
The prin~ed image of the above type ace for MICR is formed by transferring a magnetic ink onto a receiving paper by an impact printer such as typewriter.
The magnetic ink including a magnetic substallce powcler is coated and dried on a foundation such as plas~lc film to form a pressure-sensitive magntic transfer element.
Such a pressure-sensitive magnetic transfer element is disclosed in, for example, Japanese Patent Publication No. 21449/1970.
However~ the use of the pressure-sensitive magnetic transfer element results in generating noise due to impact system, and further cannot perform high printing speed. In addition, the above transfer element tends to generate voids in the printed magnetic image.

BRIEF DESCRIPTION OF THE IN~ENrION
Fig. 1 is a schematically sectional view for showing an embodiment of a heat-sensitive magnetic transfer element of the invention; and ~ ig. 2 is a explanatory view for showing a printing method using a heat-sensitive magnetic transfer element of the invention.
DFTAILED EXPLANATION OF THE INVENTION
Fig. 1 shows a heat-sensitive magnetic transfer element according to the invention comprising a heat--- '1 --resisting foundation 1, and a heat-sensitive transferring laver 2 including a ferromagnetic substance powder and having a melting temperature of 50 to :L2~C., which is measured at a heating-up velocity of 40C./min. by Meihosha-type melting point measuring device available from Meihosha ~actory Ltd.
The heat-sensitive transferring layer 2 is one layer formed by uniformly admixing a binder material of wax and/or thermoplastic resin including, if necessary, additives such as fat and oil, extender pigment, or dispersant, with the magnetic substance powder. Such a transferring layer can be obtained by means of ~lot-melt coating or solvent coating.
The magnetic substance powder is pre:Eerably included in the heat-sensitive transferring layer 2 at a range of 30 to 97 % by weight per total amount of the transferring layer 2. When the magnetic substance powder content is less than the above range, the magnetic properties of the printed image are lowered, whereby reading of MICR becomes difficult. On the other hand, when the magnetic substance powder content is more than the above range, the melt-transfer property of the transferring layer 2 and the adhesion strength of the printed image against the image receiving paper are lowered.
In the case that the heat-sensitive transferring layer 2 is provided on the heat-resisting foundation 1 by means of hot-melt coating, wax is preferably employed as a main ingredient of the binder material to prepare the heat-sensitive transferring layer. In that case, 30 to 97 % by weight of the ferromagnetic substance powder, 20 to 70 % by weight of wax, n to 30 ~ by weight of thermoplastic resin~ o to 30 % by weight of fat and oil, 0 to 30 % by weight of extender pigment and 0 to 2 % by weight of dispersant are used per total amount of the heat-sensitive transferring layer 2.
In the case that the heat-sensitive 95~
trans-Eerring ].ayer 2 is provided on the heat-resisting :Eollndati.on l by means o solvent coating, 3n to ~7 ~ by weight of t~e ferromagnetic su~s~ance powder, ~ to 2() %
by weight of wax, 20 to 7n ~ by we;.ght o:E thermoplastic resin, 0 to 30 ~ by we;ght o:E fat and oil, 0 to 3() % by weight of extender pigment and n to 2 % by weight of clispersant are used per total amonnt of the heat-sensitive trans:Eerring layer~ and are homogeneously dispersed in organic solvent such as toluene, metilyl ethyl ketone, methyl isobutyl ketone, cyclohexane, butyl butyrate, dioxane, or ethyl-benzene.
An example of the ferromagnetic substance powder is ~-Fe2O3, ~-Fe2O3 inclllding Co, Fe3O4, Fe3O4 including Co, CrO2, Co-Cr alloy, Co-Fe alloy, Co-Ni-P
alloy, Co-Ni-Fe alloy, Co-Ni-Fe-B alloy, Co-Ni-~n alloy, Fe-Mn-Zn alloy, ~e-Co-Ni-Cr alloy, Fe-Co-Ni-P alloy, Ni-Co alloy, or the like. The aspect ratio (L/D) of the ferromagnetic substance powder mentioned above is 5 : l to 2~ : 1, more preferably 5 : 1 to 1~ : 1, and the diameter o:E the same is 0.01 to 1 ~, more preferably 0.02 to 0.5 ~. Furthermore, the length o-E the ferromagnetic substance powder is preferably 0.05 to 20 ~, more preferably 0.1 to 5 ~.
An example of wax is one or more of carnauba wax, montan wax, para:Efin wax, microcystaline wax, bees wax, or the like. Due to wax contained in the heat-sensitive tranferring layer 2 as a binder material, the melt-transer property of the transferring layer 2 obtained can he effectively increased. Thus, the transferred magnetic image 5 prepared is free from the void and the break, and further has an excellent adhesion on ~he receiving paper 3. Accordingly, it is especially preferable that wax is contained in the heat-sensitive transEerring layer 2.
An example of the thermoplastic resi.n is polyvinyl chloride, polyvinyl acetate, vinyl chloride vinyl acetate copolymer, polyethylene, polypropylene, polyacetal, eth.ylene-vinyl acetate copolymer, 5~
polystyrene, low molecul~r weight polystyrene, poly-acrylic ester, polyamide, ethyl cellulose, or the like.
Furthermore, epoxy resin, xylene resin, ketone resin, petroleum resin, rosin or the derivative.s thereof, cumarone-indene resin, terpene resin, polyurethane, synthetic rubber such as styrene-butadiene rubber, polyvinyl butyral, nitrile rubber, polyacrylate rubber, ethylene-propylene rubber, or the like can be also pre:Eerably employed.
An example of the above fat and oil is animal oil, vegetable oil, mineral oil, dioctyl phthalate, tricresyl phosphate, dibutyl phthalate, or the like.
An example of the above extender pigment is calcium carbonate, magnesium carbonate, diatomaceous lS earth, kaolin, white carbon, silicic acid powder, or the like. Furthermore, an example of the dispersant is nonionic surface active agent such as di(polyoxyethylene alkylether) phosphate, tri(polyoxyethylene alkylether) phosphate, polyoxyethylene stearylamine, polyoxyethylene laurylether, polyoxyethylene oleylether, polyoxyethylene cetyle~her, po].yoxyethylene stearylarylether, or the like.
The heat-sensitive transerring layer 2 thus obtained has preferably a thickness o-f 2 to 25 ~, and the heat-resisting foundation 1 has preferably a thickness of 3 to 4~ ~.
An example of the heat-resisting foundation is a plastic film such as polyester, moisture-protected cellophane, polycarbonate, nylon, polypropylene, or a paper such as condenser paper, glassine paper.
The heat-sensitive magnetic transfer element of the invention is overlapped with the receiving paper 3 such as check, and then is printed by a thermal head 4 of the thermal printer as shown in Fig. 2, whereby the magnetic image 5 is melted and transferred on the receiving paper 3.
In that case, the heat-sensi~ive transferring ` layer 2 according to the invention can be correctly ~195~
transferred only in the portion of the tr~nsferring layer 2 corresponding to the heatillg ancl printing portion Or the thermal head ~, because the heat-sensitive transferring l~yer 2 is a melting temperature o-f 5~ to 120C., and therefore is superior in the heat-transfer property an~ the adhesion property. As ~ result, the magnetic image prepared has a very sharp profile wi~hout causing the void, the break of the character and the smudge of the receiving paper 3.
In particular, the magnetic image 5 thus obtained has a high accuracy in dimension to ensure the reading operation of MICP~ so that a high reliability can be offered.
In addition, the invention has also signi-ficant advantages that a high-speed printing can be performed without generating noise, and the preparation of bill, chec}c, credit card, pass, traffic census card, or the like can be readily and rapidly carried out, since the magnetic image 5 is prepared by using the thermal printer.
~urther, the magnetic image obtained in the invention is not limited to only the certain type face such as E13B or CMC7 mentioned above, and other certain characters are also readily prepared from the heat-sensitive magnetic transfer element by means of the thermal printer.
The invention is rnore particularly described and explained bv means of the following Examples.

Also, voids existing in the magnetic images 15 were determined by observing whether single void is included within a square gauge of 0.21)3 mm. X 0.2n3 mm.
In that case, the void existing in a line having a width of 0.660 mm. or more was determined by employing a square gauge of 0.254 mm. X n.254 mm. according to the 20 definition of JIS C 6251. The results are shown in the following Table.

Fig. 1 is a schematically sectional view for showing an embodiment of a heat-sensitive magnetic transfer element of the invention; and ~ ig. 2 is a explanatory view for showing a printing method using a heat-sensitive magnetic transfer element of the invention.
DFTAILED EXPLANATION OF THE INVENTION
Fig. 1 shows a heat-sensitive magnetic transfer element according to the invention comprising a heat--- '1 --resisting foundation 1, and a heat-sensitive transferring laver 2 including a ferromagnetic substance powder and having a melting temperature of 50 to :L2~C., which is measured at a heating-up velocity of 40C./min. by Meihosha-type melting point measuring device available from Meihosha ~actory Ltd.
The heat-sensitive transferring layer 2 is one layer formed by uniformly admixing a binder material of wax and/or thermoplastic resin including, if necessary, additives such as fat and oil, extender pigment, or dispersant, with the magnetic substance powder. Such a transferring layer can be obtained by means of ~lot-melt coating or solvent coating.
The magnetic substance powder is pre:Eerably included in the heat-sensitive transferring layer 2 at a range of 30 to 97 % by weight per total amount of the transferring layer 2. When the magnetic substance powder content is less than the above range, the magnetic properties of the printed image are lowered, whereby reading of MICR becomes difficult. On the other hand, when the magnetic substance powder content is more than the above range, the melt-transfer property of the transferring layer 2 and the adhesion strength of the printed image against the image receiving paper are lowered.
In the case that the heat-sensitive transferring layer 2 is provided on the heat-resisting foundation 1 by means of hot-melt coating, wax is preferably employed as a main ingredient of the binder material to prepare the heat-sensitive transferring layer. In that case, 30 to 97 % by weight of the ferromagnetic substance powder, 20 to 70 % by weight of wax, n to 30 ~ by weight of thermoplastic resin~ o to 30 % by weight of fat and oil, 0 to 30 % by weight of extender pigment and 0 to 2 % by weight of dispersant are used per total amount of the heat-sensitive transferring layer 2.

An example of the ferromagnetic substance powder is ~-Fe2O3, ~-Fe2O3 inclllding Co, Fe3O4, Fe3O4 including Co, CrO2, Co-Cr alloy, Co-Fe alloy, Co-Ni-P
alloy, Co-Ni-Fe alloy, Co-Ni-Fe-B alloy, Co-Ni-~n alloy, Fe-Mn-Zn alloy, ~e-Co-Ni-Cr alloy, Fe-Co-Ni-P alloy, Ni-Co alloy, or the like. The aspect ratio (L/D) of the ferromagnetic substance powder mentioned above is 5 : l to 2~ : 1, more preferably 5 : 1 to 1~ : 1, and the diameter o:E the same is 0.01 to 1 ~, more preferably 0.02 to 0.5 ~. Furthermore, the length o-E the ferromagnetic substance powder is preferably 0.05 to 20 ~, more preferably 0.1 to 5 ~.
An example of wax is one or more of carnauba wax, montan wax, para:Efin wax, microcystaline wax, bees wax, or the like. Due to wax contained in the heat-sensitive tranferring layer 2 as a binder material, the melt-transer property of the transferring layer 2 obtained can he effectively increased. Thus, the transferred magnetic image 5 prepared is free from the void and the break, and further has an excellent adhesion on ~he receiving paper 3. Accordingly, it is especially preferable that wax is contained in the heat-sensitive transEerring layer 2.
An example of the thermoplastic resi.n is polyvinyl chloride, polyvinyl acetate, vinyl chloride vinyl acetate copolymer, polyethylene, polypropylene, polyacetal, eth.ylene-vinyl acetate copolymer, 5~

An example of the heat-resisting foundation is a plastic film such as polyester, moisture-protected cellophane, polycarbonate, nylon, polypropylene, or a paper such as condenser paper, glassine paper.
The heat-sensitive magnetic transfer element of the invention is overlapped with the receiving paper 3 such as check, and then is printed by a thermal head 4 of the thermal printer as shown in Fig. 2, whereby the magnetic image 5 is melted and transferred on the receiving paper 3.
In that case, the heat-sensi~ive transferring ` layer 2 according to the invention can be correctly ~195~
transferred only in the portion of the tr~nsferring layer 2 corresponding to the heatillg ancl printing portion Or the thermal head ~, because the heat-sensitive transferring l~yer 2 is a melting temperature o-f 5~ to 120C., and therefore is superior in the heat-transfer property an~ the adhesion property. As ~ result, the magnetic image prepared has a very sharp profile wi~hout causing the void, the break of the character and the smudge of the receiving paper 3.
In particular, the magnetic image 5 thus obtained has a high accuracy in dimension to ensure the reading operation of MICP~ so that a high reliability can be offered.
In addition, the invention has also signi-ficant advantages that a high-speed printing can be performed without generating noise, and the preparation of bill, chec}c, credit card, pass, traffic census card, or the like can be readily and rapidly carried out, since the magnetic image 5 is prepared by using the thermal printer.
