BACKGROUND OF THE INVENTION
The present invention relates to a personal identification number notification comprising a piece of paper using a layer containing a fluorescent pigment in a personal identification number entry field.
[0002]
[Prior art]
Conventionally, as a PIN code notification using an ultraviolet light emitting layer, an ultraviolet light emitting layer is provided on the back side of a piece of paper on which one PIN code is to be transferred in a copy sheet consisting of a plurality of sheets. The PIN code entered on the surface of the card is copied and entered in the PIN code entry field on which the background pattern is printed by copying the ultraviolet light emitting layer. After reading and registering the PIN number entered on the piece of paper that will receive the number, the upper piece of paper is peeled off and discarded, and the PIN number is copied and entered in the PIN number entry field on which the background pattern is printed by the UV light emitting layer. Thus, a piece of paper in which the personal identification number cannot be seen is stored, and when it becomes necessary to confirm the personal identification number, the personal identification number can be visually confirmed by irradiating with ultraviolet rays. In the case of this configuration, which is a copy form, it is convenient to use it at a bank or other counter, but there is a problem of handling such as falling off due to peeling of the upper paper piece when distributing by mail or mailing. In many cases, the data recorded in the database is used to print out the address with a non-impact printer, and the printability is impaired at the time of printing.
[0003]
In order to solve the above-mentioned problem, a single personal identification number is notified, for example, as described in Japanese Patent Application Laid-Open No. 10-258594, an ultraviolet light emitting layer is provided only in the personal identification number entry field on which the background pattern is printed. It consists of a copy paper piece that is provided so that it can be peeled off, and the password is copied by the ultraviolet light emitting layer by entering the password from the upper surface of the copy paper piece. Banks, etc. read and register the code number entered on the copy paper piece, peel off the copy paper piece, discard it, and copy the code number into the code number entry field on which the background pattern is printed by the ultraviolet light emitting layer. A piece of paper in which the number is not visible is stored, and when it is necessary to confirm the password, the password is made visible by irradiating ultraviolet rays, or By forming a colored ultraviolet light emitting layer on the paper surface and entering the personal identification number directly on the surface of the ultraviolet light emitting layer, the entered personal identification number is made visible. In the bank, etc. that received it, after reading and registering the PIN number written on the UV light emitting layer surface of the PIN number entry column, cover the PIN number entry column with a matte polypropylene film so that the PIN number cannot be read. Are stored.
[0004]
However, the former one has the disadvantage that the manufacturing process for notifying the PIN number becomes complicated because the copy paper piece provided with the ultraviolet light emitting layer in the PIN number entry field needs to be detachably attached, and the price increases. In the latter case, since the ultraviolet light emitting layer is colored in dark color, the light emission effect when irradiated with ultraviolet light is reduced, making it difficult to read the personal identification number even when irradiated with ultraviolet light. There was a drawback that it was not possible to make a background pattern in order to hide the image.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a low-cost PIN code notification with a simplified structure, using an ultraviolet light emitting layer in the PIN code entry field.
[0006]
[Means for Solving the Problems]
A code number entry field is provided in a predetermined area of the form paper piece, and the code number entry field is not printed solidly with dark ink on the surface of the form paper piece. It is a personal identification number report in which an ultraviolet light emitting layer solid-printed with light-colored ink is laminated in order. In this case, when the customer makes an application, the personal identification number is entered directly on the UV light emitting layer surface of the personal identification number entry field. However, since the personal identification number is generally entered with a black pen, the personal identification number entered and the dark color print are printed. Since there is a certain degree of contrast between the surface color of the personal identification number entry column composed of the layer and the ultraviolet light emitting layer and there is a difference in surface gloss, the personal identification number entered is visible. On the bank side that received the application form, after confirming and recording the entered code number, a matte polypropylene film or the like having a good ultraviolet light permeability is attached to the code number entry field and stored.
[0007]
In the above PIN code notification, after the PIN number is entered in the PIN number entry column, the PIN number entry column is covered, and a polypropylene matte film or polypropylene non-woven fabric with good UV transparency is attached. Since the surface of the polypropylene matte film or polypropylene nonwoven fabric reflects light irregularly, the PIN number entered in the PIN number entry field cannot be seen, but it is necessary to keep the PIN number notification in this state and check the PIN number. When it occurs, the ultraviolet light emitting layer emits light emitted from the polypropylene matte film or the polypropylene nonwoven fabric by irradiating the PIN code column with the polypropylene matte film or polypropylene nonwoven fabric affixed with an ultraviolet lamp. Therefore, the password can be confirmed.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an embodiment of a personal identification number notification according to the present invention, FIG. 2 is a sectional view taken along the line II in FIG. 1 showing the configuration of a personal identification number entry column, and FIG. 3 is a personal identification showing a state where the personal identification number is entered (B) in the number entry column is a plan view, (b) is a cross-sectional view, and FIG. 4 is a cross-sectional view of the code number entry column in a state where the security code notification is stored, where 1 is a form paper piece and 2 is a code number entry. Column, 2a represents an ultraviolet light emitting layer, 2b represents a dark print layer, 3 represents a personal identification number, and 4 represents a coating film.
[0009]
An embodiment of the personal identification number notification of the present invention is as shown in FIG. 1 and FIG. 2, and the personal identification number notification is provided with a personal identification number entry field 2 in a predetermined area of the slip 1, and an address and name entry field, An account number entry field, a delivery stamp field, etc. are provided. The customer enters the personal identification number directly in the personal identification number entry field 2 with a ballpoint pen or the like, fills in other necessary items, and submits it directly as a personal identification number notification.
[0010]
As shown in FIG. 2, the code number entry field 2 has a dark printing layer 2b and an ultraviolet light emitting layer 2a laminated in this order on the surface of the paper sheet 1. The dark print layer 2b has a color tone that does not have a large contrast with the black color of the ballpoint pen on which the PIN code is written, for example, a solid print layer that uses dark ink such as slightly light black, gray, or brown, or slightly light black, gray, brown, etc. This is a tint block printing layer using dark ink. The ultraviolet light emitting layer 2a is printed with a colorless or lightly colored ink containing a fluorescent pigment that emits light when irradiated with ultraviolet light. The type of ink containing the fluorescent pigment is arbitrary such as flexographic ink, gravure ink, silk printing ink, hot melt ink, etc., but in order to enhance the light emitting effect by irradiation with ultraviolet rays, it is formed to a thickness of 3 to 10 μm. preferable.
[0011]
The personal identification number is entered directly on the surface of the ultraviolet light emitting layer 2a in the personal identification number entry column 2 with a ballpoint pen or the like. The state where the personal identification number 3 is entered in the personal identification number entry field 2 is as shown in FIGS. The personal identification number 3 entered on the surface of the ultraviolet light emitting layer 2a in the personal identification number entry column 2 in which the dark color printing layer 2b and the ultraviolet light emitting layer 2a are laminated in order on one side of the form paper is clear because of the dark color printing layer 2b. Although it is difficult to read, the code number entered by changing the viewing angle because there is a difference in density between the entered code number 3 and the surface of the code number entry field 2 and the reflectance of light on both surfaces is different. Can be confirmed accurately.
[0012]
In the bank etc. that received the PIN code notification, after confirming and registering the PIN number 3 entered in the PIN number entry field 2, when storing the PIN number report, cover the PIN number entry field 2 Because the light is diffusely reflected on the surface of the matte film or non-woven fabric by sticking a matte film or non-woven fabric made of polypropylene with good transparency, the secret code entered in the UV light emitting layer 2a in the PIN number entry column 2 No. 3 is not visible even if the viewing angle is changed, and there is no risk of being seen by others. When it is necessary to confirm the personal identification number 3, the ultraviolet light emitting layer 2a emits light by irradiating the surface of a polypropylene matte film or polypropylene non-woven fabric having good ultraviolet transparency with an ultraviolet lamp. Since it passes through a matte film or a polypropylene non-woven fabric, the password can be confirmed.
[0013]
The fluorescent pigment used in the ultraviolet light emitting layer 2a is changed to visible light having a longer wavelength by irradiating with ultraviolet light having a wavelength of 254 to 365 nm without emitting light under ordinary sunlight or a fluorescent lamp. It emits light and emits light, and pigments mainly composed of oxides such as calcium, barium, magnesium and zinc, silicates, phosphates and tungstates can be used. For example, a fluorescent pigment mainly composed of Zn ₂ SiO ₄ / Mn having an excitation spectrum peak of 254 nm and an emission spectrum peak of 520 nm can be suitably used. As an example of the composition of the hot melt type ink containing the above fluorescent pigment, the fluorescent pigment is 35 to 45%, the mineral oil is 5 to 15%, the wax is 35 to 45%, and the ethylene-vinyl acetate copolymer is 3 to 8%. The hydrocarbon-based resin is 3 to 8%.
[0014]
【The invention's effect】
A code number entry field is provided in a predetermined area of the form paper piece, and the code number entry field is not printed solidly with dark ink on the surface of the form paper piece. Since the PIN number notification is made up of the UV light emitting layer that is solidly printed with light ink in order, the PIN number is entered directly on the UV light emitting layer surface of the PIN number entry column when the customer makes an application. However, since the personal identification number is generally entered with a black pen, there is a certain difference in density between the personal identification number entered and the surface color of the personal identification number entry column composed of the dark color printed layer and the ultraviolet light emitting layer. At the same time, because of the difference in surface gloss, the entered code number is visible. In addition, the bank that has received the application form confirms and registers the entered code number, and when storing the code number, a matte polypropylene film or the like is pasted in the code number entry field.
In the above PIN code notification, after the PIN number is entered in the PIN number entry column, the PIN number entry column is covered, and a polypropylene matte film or polypropylene non-woven fabric with good UV transparency is attached. Since the surface of the polypropylene matte film or polypropylene nonwoven fabric reflects light irregularly, the PIN number entered in the PIN number entry field cannot be seen, but it is necessary to keep the PIN number notification in this state and check the PIN number. When it occurs, the ultraviolet light emitting layer emits light emitted from the polypropylene matte film or the polypropylene nonwoven fabric by irradiating the PIN code column with the polypropylene matte film or polypropylene nonwoven fabric affixed with an ultraviolet lamp. Therefore, the password can be confirmed.
