Abstract

PURPOSE:To make the falsification of printed information with an elecrtrostatic printing type printer impossible by a method wherein a printing layer printed with ink by a printing method such as solid printing, pattern printing or the like is provided on the top surface of the base sheet material and further a printed image fixing layer is provided on the top surface of the printing layer. CONSTITUTION:In the printing sheet 1 concerned, the expression of the entry column of the name of feed, account number and the like, advice information and the like are arranged by printing. In this case, to the item entry column 3, printing layer 4 printed by the printing method such as solid printing, pattern printing or the like with light-colored ink is annexed. Further, to the top surface of the printing layer 4, printing image fixing layer 5 is annexed in the same region as that of the printing layer. With the printing of printed information in the item entry column 3, printed image is directly fixed to the printing image fixing layer 5 so as to improve the degree of fixation of the printed image. Thus, the printing sheet 1, the printed information on which can not be falsified with an electrostatic printing system printer, can easily be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing sheet, and more particularly to a printing sheet used for various tickets, gift certificates, stock certificates, protective deposit certificates, deposit certificates and the like.

[0002]

2. Description of the Related Art Recently, a printing machine of an electrostatic printing type called a laser printer has become popular because of its high print processing capability and required sheets, for example, financial institutions notify customers. A letter used to send information,
This electrostatic printing machine is also used when outputting various variable information to a sheet such as a postcard. On the other hand, since such electrostatic printing type printing machines have become widespread, a device for providing a print image fixing layer on the sheet side may be devised in order to improve the fixation of the print image, that is, the toner. Has become.

Such a printed image fixing layer has been provided on the sheet base material from the following materials. For example, fine silica powder 50 to 95% by dry weight and binder 5 to 50
It is formed by applying a composition comprising dry weight%, and a preferable blending ratio is about 25 to 45% of fine silica powder dispersed in water at a solid content of 20%, and 10% as a binder.
Partially hydrolyzed polyvinyl alcohol in solution 5 → 0%,
And about 25-45% water. And more specifically,
Cabo Spers S-109 as fine silica powder
(Product name) 35.95%, binder 10%,
Vino1540 (trade name) 28.10%, and water The composition is prepared in mixing ratio of 35.95%, 0.4~2.8g / m ² of coat weight, for example 1.1 g / m ² / Coated on the surface. Application of this composition to a sheet base material is performed by a commonly used conventional method such as flexography, gravure, reverse roll, and air knife.

[0004]

By the way, paying attention to the high printing capacity of the electrostatic printing machine, and printing the reservation information and the amount information on the sheet, for example, by using the sheet on which the printed image is well fixed. Various tickets and deposit certificates are continuously created. When creating these tickets or certificates of deposit, in order to improve the quality and prevent the forgery of the sheet,
Or, since the background printing, the logo mark printing, etc. are pre-printed by a required printing method such as solid printing or tint block printing for partial emphasis, printing is performed on a sheet having a print image fixing layer. Is loaded in the output device, and the printing process is performed on the entire sheet or on the sheet on which the above-described printing is performed in this manner, and a ticket, a certificate of deposit, or the like is created.

However, as described above, a sheet prepared for a ticket, a certificate of deposit, or the like has a layer structure of a print layer, a print image fixing layer, and a sheet base material from the upper layer, and a printed print image and a print image fixing are formed. The result is an intervening print layer between the layers. For this reason, the degree of fixing of the printed image becomes low, and there is a disadvantage that the output information such as the reservation number as a ticket and the display amount of the deposit certificate is easily tampered with.

In view of the above-mentioned circumstances, the invention has an object to prevent the degree of fixation of a printed image from being lowered, and prevents the printed image from being tampered with when variable information is output to create a ticket or a certificate of deposit. The purpose is to

[0007]

The present invention has been made in view of the above-mentioned problems, and a printing layer formed by printing an ink on a sheet base material by a required printing method such as solid printing or tint block printing. The present invention provides a printing sheet characterized in that a printing image fixing layer is provided on the printing layer to solve the above problems.

[0008]

In the present invention, the printed image is directly formed on the printed image fixing layer, and the degree of fixing of the printed image is increased.

[0009]

The present invention will be described in detail below with reference to an embodiment shown in FIGS. In the figure, 1 is a printing sheet used as a certificate of deposit, and the printing sheet 1 is
In addition to the prescribed item description field 3 on the sheet base material 2, a certificate name, an account number entry field, etc., notification information, etc. are provided by printing. In addition, a printing layer 4 formed by printing a light-colored ink by solid printing, tint block printing, or the like is provided in the item description column 3 (see FIG. 2), and the same area is formed on the printing layer 4. A print image fixing layer 5 is provided.

As described above, in the item description column 3, the printing layer 4 is provided on the sheet base material 2, and the print image fixing layer 5 is further provided thereon, and in the item description column 3 of the printing sheet 1. By printing the print information on the other hand, the print image is directly fixed on the print image fixing layer 5, and the action of the print image fixing layer 5 causes the print image to be extremely fixed. .

In the embodiment shown in FIGS. 1 and 2, the print layer 4 and the print image fixing layer 5 are provided in the same area, but in the present invention, at least the area of the print layer 4 corresponding to the required print portion is the print image. It may be covered with the area of the fixing layer 5, and as shown in FIG. 3, the print image fixing layer 5 is provided only in the area set as the print portion on the print layer 4, and the print image a is formed thereon. Alternatively, as shown in FIG. 4, the print layer 4 partially disposed is entirely covered with the print image fixing layer 5, and as shown in FIG. 5, the print image fixing layer 5 is covered with the sheet base material 2. It may be provided on all of the above.

[0012]

As described above, according to the printing sheet of the present invention, the printing layer formed by printing the ink by the required printing method such as solid printing or tint block printing is provided on the sheet base material. Since the printing image fixing layer is provided on the printing layer, the printing image printed on the printing sheet is directly fixed on the printing image fixing layer.
The degree of fixing of the printed image becomes extremely high due to the action of the fixing layer, making it possible to easily create various sheets that cannot be tampered with by using an electrostatic printing printer. The effect is extremely high.
