[Prior art]
Conventionally, when checks and promissory bills issued by customers (individuals and corporations) are processed at financial institutions, the input processing of the amount printed by the check writer is performed by terminal input while visually checking.
[0003]
The above check writer prints the amount of money by forming embosses with vertical stripes by pressing on the gold sheet column (the amount of money is printed) on the securities sheet while applying stamp ink to the convex type. This is a tool to prevent tampering, and the degree of embossing and the degree of sticking of the stamp ink varies depending on the individual checkwriters possessed by the customer, and also the density varies depending on the person who prints. There are many current situations.
[0004]
Information such as the name of a financial institution determined from the outset on securities paper is printed with magnetic ink or with a sufficient density so that it can be read with OCR. However, since the customer prints in the gold seat column, it is not always printed at a density sufficient for machine reading for the above reasons, and this is a problem in automatic processing by the machine. It was one.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
The present invention relates to a form of securities represented by, for example, a check or a promissory note. More specifically, as shown in FIG. 2, printing is performed by a check writer on a gold washer column (20) at an arbitrary position. The present invention relates to a securities sheet for obtaining securities (1) having a concentration such that the numbers and symbols of the amount (K) to be processed are reliably read and processed by a machine.
[0014]
Therefore, first, the invention of claim 1 includes a sheet body (30) having a horizontally long washer column (20) on which the amount of money is to be printed by a check writer as shown in the front view of FIG. This is a securities sheet (2) in which a carbon copy paper piece (10) having a width (WC) that is at least wider than the width (WK) of the gold column (20) is adhered so as to cover the gold column (20). .
[0015]
In the invention of claim 2, the carbon copy paper piece (10) is attached as shown in the perspective view of FIG. 1 (b) and the BB cross-sectional view of FIG. 1 (a). In addition, on the right and left edges of the base paper (12) of the carbon copy paper piece (10) composed of the carbon ink layer (14) laminated on the base paper (12), that is, on the surface (30a) of the paper body (30) (20) It consists of the peelable adhesive layer (16) laminated | stacked on the part corresponded out of the right-and-left end (20a, 20b). Therefore, the carbon ink layer (14) is stuck so as to completely cover at least the gold column (20).
[0016]
The peelable adhesive layer (16) may be laminated on the left and right edges of the carbon ink layer (14) laminated on the entire surface of the base paper (12), but can be peeled off from the carbon ink layer (14). Considering the fear that the adhesiveness of the adhesive layer (16) is inferior, it is preferable to laminate directly on the left and right edges of the base paper (12) as shown in FIG. 1 (b). Therefore, it is better to laminate the carbon ink layer (14) on the portion excluding the left and right edges of the base paper (12). Further, as shown in FIG. 1 (a), a carbon copy paper piece (10) having a wider vertical width than the metal washer column (20) may be provided, and a peelable adhesive layer may be provided on the upper and lower edges thereof.
[0017]
Therefore, the peelability means that the peel strength (also referred to as adhesive strength) between the adhesive layer (16) and the surface (30a) of the paper body (30) is 50 to 200 gf. This is because after the carbon copy paper piece (10) of the securities paper (2) of the present invention is pressed and printed with a check writer, the carbon copy paper piece (10) is peeled off and the amount (K) as shown in FIG. In order to obtain the printed securities (1), the peelable adhesive layer (16) and the paper body (30) are easily peeled off. If this peel strength is less than 50 gf, it will be peeled off when not needed for storage or operation before printing, and if it exceeds 200 gf, it will not peel easily even if it is peeled off, and peeling of the peelable adhesive layer (16) will occur. It is not preferable because it occurs and the adhesive remains in the paper body (30).
[0018]
When the securities copy paper (2) having the above-described configuration is pressed from above the carbon copy paper piece (10) with a check writer and the carbon copy paper piece (10) is peeled off, for example, the check writer and the person who prints are different. However, the carbon ink layer (14) is transferred to the washer column (20) of the paper body (30), and numbers and symbols with a PCS value of 0.8 or more can be stably obtained, and the amount printed can be assured. You can get machine-readable securities.
[0019]
Further, the invention of claim 3 is a securities paper (2) in which the carbon ink layer (14) shown in FIGS. 1 (b) and 1 (c) is a layer containing a fluorescent pigment. is there.
[0020]
It goes without saying that the numbers and symbols (amounts) of which the carbon ink layer (14) containing the fluorescent pigment is pressure-transferred with a check writer can be reliably read and processed by a machine. For example, money numbers and symbols are colored under a black light as a true / false determiner, making it possible to more easily determine the authenticity of securities.
[0021]
In particular, the material of the carbon copy paper piece (10) will be described below.
First, as the base paper (12) constituting the carbon copy paper piece (10), a thin copy paper that can be transferred by pressing with a check writer or a typewriter is used. For example, a KS copy bright having a basis weight of about 40 g / m ² ( Oji Paper Co., Ltd.), MCP (Mishima Paper Co., Ltd.), JCR (Honshu Paper Co., Ltd.), NBCP (Jujo Paper Co., Ltd.), and the like. In addition, synthetic paper having a thickness of about 10 μm, which has recently been used for courier services, can also be used.
[0022]
The carbon ink layer (14) includes pigments (mainly black pigment carbon black and oil black, and other blue, red and white pigments) 5 to 35% by weight, oil (non-drying oil such as machine oil) Using a general hot-melt carbon ink of about 100 ° C. in which 20 to 40% by weight and wax (plant wax, paraffin wax, polyethylene wax, etc.) 30 to 70% by weight are dispersed and kneaded, rubber convex flexo is used. It is obtained by part-coating the above-mentioned base paper (12) by a method or a gravure method.
[0023]
Further, as the peelable adhesive layer (16), a pressure-sensitive adhesive (also referred to as an adhesive) is suitable, and among them, penetration into the base paper (12), emulsion type with good adhesion, water-soluble A mold or a hot melt mold is preferred. For example, the emulsion type includes an acrylic pressure-sensitive adhesive mainly composed of an acrylic ester, and the water-soluble type includes an acrylic acid copolymer, an acrylamide copolymer, and polyethylene oxide. . Examples of the hot melt type include ethylene vinyl acetate copolymer (EVA), block copolymers such as styrene-butadiene or styrene-isoprene, polyamides, acrylic ester copolymers, and the like, and heating at 150 to 200 ° C. It can be applied by melting at a temperature, and various additives and compatible resins can be added to these resins for adjusting the peel strength.
[0024]
The pressure sensitive adhesive as described above is adjusted to a viscosity corresponding to each printing method, and a rubber convex flexo method is provided on the left and right edges or the peripheral edge of the base paper (12) constituting the horizontally long carbon copy paper piece (10). Part coating can be performed by either a gravure method or a screen method to form a peelable adhesive layer (16).
[0025]
The carbon copy paper piece (10) in which the carbon ink layer (14) and the peelable adhesive layer (16) are part-coated on the base paper (12) as shown in FIG. As shown in FIG. 3, the peelable adhesive layer (16) surface is affixed to a release paper (50) coated with silicon (52), and this release paper is used during the manufacture of securities paper. The carbon copy paper piece (10) may be peeled off from (50) and attached so as to cover the metal washer column (20) of the paper body (30) as shown in FIG. 1 (c).
[0026]
Furthermore, as the fluorescent pigment to be contained in the carbon ink layer (14), there are those made of a fluorescent dye and a synthetic resin solid solution and those made of an inorganic pigment, but the carbon ink layer (14) is a wax-based one. Because of the hot melt type, the former fluorescent dye is inferior in heat resistance and may inhibit light emission. Therefore, the latter inorganic pigment having excellent heat resistance is preferably used. As the inorganic fluorescent pigment, for example, Zn ₂ SiO ₄ / Mn, CaWO ₄ that emits light only in the wavelength region of 200 to 300 nm, ZnS / Mn that emits light only in the wavelength region of 300 to 450 nm, or the like These mixtures are preferably used, and the above-mentioned carbon ink is mixed with approximately the same amount of fluorescent ink dispersed and mixed, for example, 20 to 50% by weight of the fluorescent pigment, 15 to 40% by weight of oil, and 20 to 50% by weight of wax. The carbon ink layer (14) containing a fluorescent pigment can be formed from the ink thus obtained by a rubber convex flexo method or a gravure method.
[0027]
