Description

[Detailed description of the device]

[0001]

[Industrial applications]

 Since the present invention relates to a laminated sheet capable of printing the output of a computer, it has confidentiality of printed contents and is completely waterproof, and is used for communication such as postcards for specific addresses. It is about what you do.

[0002]

[Prior art]

 Traditionally, postcards or envelopes have been used to mail cards printed with computer output. Invoices for gas, tap water, electricity, telephone charges, etc. may be sent by postcard, and these contents may also belong to the confidentiality of privacy depending on the personality of the individual or depending on the situation. It is better to keep it secret. On the other hand, particularly confidential items, such as loan invoices and salary statements, are sent by mail or by depositing a card with the computer output printed in an envelope. However, it takes time and effort to put the printed card in the envelope, and it is necessary to use a window envelope so that the address can be seen from the outside, which is expensive. In addition, if it is delivered in the rain, it may get wet and become illegible.

[0003]

[Problems to be solved by the device]

 It is an object of the present invention to provide a waterproof laminate sheet for pressure-sensitive printing of computer output, which does not require an envelope and whose confidentiality is protected.

[0004]

[Means for Solving the Problems]

 The inventors of the present invention laminated a plastic film as a cover for a printing card such as a postcard, type-printed on the plastic film, and used a pressure-sensitive copying system provided between the plastic film and the card. Depending on the printing method, the privacy of the contents such as postcards can be maintained, and it is possible to prevent the printed surface from becoming unclear due to rain or the like.Moreover, since it is printed on a plastic film thinner than paper, The present invention has been completed with the idea that pressure-sensitive printing type characters that tend to be unclear usually can be made clear.

That is, according to the present invention, a plastic cover film coated with a transfer dye layer is laminated on a plastic printing card so that the coated surface faces the surface of the plastic printing card. The present invention provides a pressure-sensitive laminated sheet for fixing, in which a plastic cover film is provided with perforations along the inside of the fixed portion. The plastic printing card used in the present invention uses a plastic sheet having a printable surface, for example, a writable surface-treated plastic sheet such as synthetic paper or a roughened sheet. The print card of the present invention may be a preprinted form part. In this case, a numerical value or other information of a certain character from the computer can be entered in the blank of the above-mentioned form by the type printing on the plastic cover film. As the transfer dye layer used in the present invention, those used in the known pressure-sensitive transfer system used in the pressure-sensitive printing method can be appropriately used. That is, for example, it is possible to use a printing card in which a coating material containing a microcapsule containing a dye is applied to the back surface of a plastic film and a developer is applied to the opposite surface of this coating layer. . When printing is done from the top of the plastic film to this laminated system, the dye inside is transferred to the facing surface while the capsule on the back side is destroyed by type pressure, and the color develops by acting with the dye and the developer on the facing surface. It is possible to use a method in which the printing appears. Further, for example, a method in which a carbon-containing transfer ink is simply applied to the back of the upper surface, and this is pressed by the type pressure from above the upper surface film, and the carbon layer is transferred to the facing surface of the printing card for printing. Can be used.

The present invention will be described in more detail with reference to the drawings of the embodiments. One of the embodiments of the present invention is, as shown in FIGS. 1 and 2, on a print card 2, an inner surface is roughened by corona discharge, and a carbon-containing transfer ink layer (roughened The rectangular plastic cover film 1 coated with the treatment and the carbon ink layer (not shown) is laminated, and the periphery thereof is fusion-fixed by fusion-bonding. Eyes 3 are provided. This fusion fixing can be performed by heat sealing or a heat sensitive adhesive. At the lower left corner of the perforation 3, a perforation portion of the plastic cover film 1 is cut out by a corner cut 5. A matte ink is applied to the outer surface 8 of the upper half of the plastic cover film 1 for writing. In this example, the output from the computer was typed into the blank area of the preprinted form from above the plastic cover film 1 and the carbon layer applied to the plastic film by the type pressure was applied. Characters can be written on the lower half portion 9 ′ of the print card by being type-printed, which is transferred onto the print card 2. In this embodiment, since the periphery of the print card 2 and the opaque plastic cover film 1 are fixed by an adhesive, the contents of the print card cannot be seen unless the plastic cover film 1 is broken. In this embodiment, the plastic cover film 1 is made easy to tear by the perforations 3. Furthermore, there is a notch of the corner cut 5 in the lower left corner so that it can be easily peeled from here with a nail. It can be peeled off from here to break the perforations 3 and see the contents of the printed card.

Instead of the combination of perforations and notches as in the present embodiment, as shown in FIG. 5, the perforations of intermittent cuts that penetrate the perforation surface up to three sides and penetrate the print card. Can be provided. The plastic cover film 1 can be opened by cutting off the edges of the print card from the perforations. The perforations 3 of this embodiment intermittently cut the plastic cover film 1, but the intermittent cutting does not penetrate the printed card 2. In the present embodiment, the sewing machine surface 3 is provided on four sides, but in some cases, it may be formed on only a part. Matte ink is applied to the writing portion 8 on the upper half of the plastic cover film 1 so that writing can be performed. This writing portion is a portion for writing an address and the like, and this can be written by a type output by a computer or by handwriting. As the ink used for the writing portion, inks in which an inorganic substance is mixed, such as matte ink, can be used. In addition, any material can be used as long as it is writable, such as a material that is roughened by corona discharge to provide writability. Further, instead of imparting writability by surface treatment of the plastic film, a plastic film having a writable surface such as synthetic paper can be used. In this case, as one aspect of the synthetic paper, for example, a method of providing a foam layer on the surface and a type of blending a filler and then stretching it to form voids on the surface are known to have both roughening and opaqueness at the same time. As achieved, it can be suitably used in the present invention. The type for the writing portion is different from the printing for the lower half in that ink is essential. Therefore, the upper half of the printed card 2 can be written at the same time as the upper half of the plastic cover film 1. The lower half of the description that requires secrecy is type printing that does not use ink, and can be printed only on the print card 2 by transferring the carbon layer applied to the back of the plastic cover film 1.

The laminated sheet of this embodiment is of a single-leaf type, and is used for a method of continuously and automatically feeding one by one the laminated sheet of this embodiment and type-printing computer output thereon. To do. Further, it is possible to form a three-layer laminated sheet structure in which a copy sheet is reversibly adhered to the laminated sheet of this embodiment with a pressure sensitive adhesive. In this case, the printing type can be entirely implemented by using ink, and this copy sheet is printed in the same format as the printing card 2 and the same printing is performed. Further, the number of copy sheets can be increased as needed. In this case, the situation in which confidential printing is not printed on the plastic cover film 1 is the same as in the second embodiment. Next, another embodiment of the present invention shown in FIGS. 3 and 4 is the case of a continuous type sheet having guide holes (merged punches) on both sides used for the most commonly used computer output. The laminated sheet of this example has three laminated structures. A copy sheet 11 is provided on the uppermost layer, a plastic cover film 1 is provided on the intermediate layer, and a continuous printing card 2 is provided on the lower layer to form a continuous laminated structure. The structure of the intermediate layer, the lower layer, and the laminated surface is the same as that of the above-mentioned embodiment (Fig. 1), but the upper half 8 of the front surface of the plastic cover film 1 as the intermediate layer contains a mat ink and a developer. An address or the like can be printed on the surface of the plastic cover film 1 by transferring the dye-containing capsule that has been applied and is applied to the inner surface of the upper half of the copy sheet 11. (Matt ink layer, developer layer, capsule layer not shown).

In this embodiment, matte ink is applied to the entire front and back surfaces of the plastic cover film 1. The matte ink coated surface in the table imparts writability to the surface of the film, and the matte ink coated surface on the backside is not essential to the present invention, but is desirable because it has the effect of increasing the adhesiveness to the transfer dye capsule layer. . In order not to print secret contents on the plastic cover film 1, the method of applying the dye-containing capsules only to the upper half of the back surface of the copy sheet 11 or conversely, applying the dye-containing capsules to the entire surface, Either of the methods of applying the color developer only to the upper half of the front surface of the plastic cover film 1 can be adopted. Further, as a method of dividing the pressure-sensitive printing portion on the front surface of the plastic cover film 1 as described above, each pressure-sensitive printing agent is applied to the entire surface of both sides, and then one of the predetermined surfaces is desensitized. It is possible to employ a method of printing ink to prevent contact between the dye of the capsule and the color developer. When the method of applying the entire surface of the plastic cover film with a matte ink or the like is adopted, it is convenient because the plastic film can be made opaque and writable. Due to this laminated structure, when the computer output is written on the copy sheet 11 on which the form is printed in advance using the ink tape, the computer output is printed on the plastic cover film 1. Among them, the upper half is printed on the plastic cover film 1, but the computer output corresponding to the lower half is not written on the plastic cover film 1. Then, the same description as the copy sheet 11 will be written on the print card 2.

The computer output continuous laminated sheet used in this embodiment is composed of three layers as described above, and after the computer output is written on the surface of the copy sheet 11 of the continuous laminated sheet, the cutout line 12 is used. The laminated sheet can be cut from the border paper 13 provided with the guide holes 10 on both sides and from the upper and lower laminated sheets. The perforation line 12 is formed by an intermittent sewing surface that penetrates all three layers. In the case of the present embodiment, the copy sheet 11 is not adhered to the lower layer at the periphery, and therefore the copy sheet 11 is released from the lower layer when cut. You can save this as a copy. Before this cut-out sheet is cut out, the three edge sheets 13 are bonded and fixed. When the computer output is continuously printed on the continuous output paper of this embodiment and then the print card portion is cut off by perforations, the copy paper 11 is released, and then the case of the first embodiment. The same as the two-layer laminated sheet after printing by computer output is obtained. Since the print card 2 is a thick plastic sheet, heat sealing can be used for the seal portion around the rectangle. In this way, when the plastic sheet is used for the print card 2, the waterproof performance and the confidentiality retention are perfected. As shown in FIG. 5, the perforations for opening the present invention are provided on the inner three sides of the peripheral sealing portion, and the outer edges of the perforations are cut off together with the laminated structure to form a cover film and a printing sheet. It is convenient because you can read the printed contents by simply flipping the cover film toward the upper edge and it becomes two sheets that are fixed at the upper side.

[Effect of device]

 Since the laminated sheet for communication printing of the present invention cannot be restored once it is opened during communication, it can be identified that it has been opened, so that it can indirectly protect the same privacy as a sealed letter. . In addition, since both sides are plastic sheets, it is possible to prevent the printed surface from bleeding in rainwater, etc. Moreover, it is possible to easily and completely seal the circumference of the two laminated layers by heat. Since pressure-sensitive printing is performed through a flexible plastic film, clearer printing can be performed than when pressure-sensitive printing is performed through paper. Further, the laminated printing sheet of the present invention can be used as continuous paper or single-leaf paper for computer output, which allows contents to be printed from the outside of the sealing sheet to the internal print card depending on the type of computer output. Can be listed. In addition, if you type-print it on a copy sheet, when you copy it to the lower plastic film, for example, selectively write only the upper half of the address etc. You can In this case, printing is convenient because ink can be used for both the upper and lower parts.
