BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated sheet capable of printing the output of a computer, which keeps the secret of the printed contents and is completely waterproof, and is intended for a specific address such as a postcard. Related to those used for communication communication, etc.

[0002]

2. Description of the Related Art Conventionally, a card printed with an output from a computer is mailed by a postcard or an envelope.
Invoices for gas, tap water, electricity, telephone charges, etc. may be sent by postcard, and these contents may also belong to the privacy secret depending on the personality of the individual or depending on the situation. Is desirable. On the other hand, particularly confidential items such as loan bills and salary statements are sent by mail or by depositing a card with 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 windowed envelope so that the address can be seen from the outside, which is expensive. In addition, when it is delivered in the rain, it may get wet and become illegible.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a computer-output waterproof laminated sheet for pressure-sensitive printing, in which confidentiality of contents is protected and which does not require an envelope.

[0004]

Means for Solving the Problems The inventors of the present invention laminated a plastic film as a cover of a printing card such as a postcard, type-printed on the plastic film and provided between the plastic film and the card. With the pressure-sensitive copying system, the privacy of the contents such as postcards can be maintained depending on the printing method, and it is possible to prevent the printed surface from getting unclear due to rain or the like. Since it is printing, the present invention has been completed with the idea that there is an advantage 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 composed of dye-containing microcapsules is coated on a plastic printing card coated with a color developer so that the coated surface is a plastic printing card surface. A laminated sheet for pressure-sensitive printing is provided, in which the periphery of both layers is fixed, and a plastic cover film is provided with cuts by perforations along the inner side 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 a synthetic paper or a roughened sheet. A developer for the transfer dye in the microcapsules applied to the cover film is applied thereon. As the print card of the present invention, a print card on which the form portion is printed in advance can be used. In this case, a numerical value or other information of a certain character from a computer can be entered in the blank of the above-mentioned form by type-printing on the plastic cover film. As the transfer dye layer used in the present invention,
A known pressure-sensitive transfer system used for the pressure-sensitive printing method can be used. That is, for example, it is possible to use a printing card in which a coating material containing microcapsules containing a dye is applied to the back surface of a plastic film and a developer is applied to the opposite surface of the coating layer. When type printing is performed on this lamination system from above the plastic film without using ink, the dye inside is transferred to the facing surface while the capsule on the back side is destroyed by the type pressure, and the color developer on the facing surface And the color appears and the print appears. However, since it is covered with the cover film, it cannot be read from the outside immediately after printing. At this time, if a normal paper is placed on the cover film and type-printed with ink, a printing paper for printing can be printed. With this copy sheet, the printed contents can be confirmed.

The present invention will be described in more detail with reference to the drawings of the embodiments. One embodiment of the present invention is shown in FIGS.
As shown in FIG. 2, the inner surface of the print card 2 is roughened by corona discharge, and a carbon-containing transfer ink layer (the roughening treatment and the carbon ink layer are not shown) is applied thereon. Rectangular plastic cover film 1
Are laminated, and the periphery is fused and fixed by fusion bonding 4,
A perforation 3 is provided inside the fusion fixing 4. This fusion fixing can be performed by heat sealing or a heat sensitive adhesive. Corner cut 5 at the lower left corner of perforation 3
Due to this, the perforations of the plastic cover film 1 are cut out. And plastic cover film 1
A matte ink is applied to the outer surface 8 of about the upper half of the upper part to enable writing. In this embodiment, the output from the computer is 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 pressure of the type is printed. Characters can be type-printed on the lower half portion 9'of the printing card by being transferred onto the 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 easily broken by the perforations 3. further,
Since there is a notch of the corner cut 5 in the lower left corner, it is easy to peel it 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 the perforations and the notches as in this embodiment, as shown in FIG. 5, the perforations of the intermittent cuts that penetrate the perforation surface to the three sides and penetrate the print card are provided. Can be provided. The plastic cover film 1 can be opened by cutting all 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 cut does not penetrate the printed card 2. In the present embodiment, the sewing machine surface 3 is provided on all sides, but in some cases, it may be a part thereof. 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 containing an inorganic substance such as matte ink can be used.
Further, 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 foamed layer on the surface and a type in which a filler is blended and then stretched to provide a void on the surface achieves roughening and opacity at the same time. However, it can be suitably used in the present invention. The type for the writing portion is different from the printing of 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, which requires confidentiality, is type printing that does not use ink, and can be printed only on the printing 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 the laminated sheets of this embodiment one by one and type-printing a computer output thereon. Is. 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 the 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 the 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.
This is the case of a continuous type sheet that has guide holes (merged punches) on both sides and is 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-described embodiment (FIG. 1),
The upper half 8 of the front surface of the plastic cover film 1 as an intermediate layer is coated with a color developer together with the matte ink, and by transferring the dye-containing capsules coated on the inner surface of the upper half of the copy sheet 11, the plastic cover is covered. An address or the like can be printed on the surface of the film 1.
(The matte ink layer, developer layer, and capsule layer are 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 application surface in the table imparts writability to the surface of the film, and the matte ink application surface on the back surface is not essential for the present invention, but is desirable because it has the effect of increasing the adhesiveness with the transfer dye capsule layer. . On the plastic cover film 1, a copy sheet 1
Either the method of applying the dye-containing capsule to only the upper half of the back surface of No. 1 or the method of applying the dye-containing capsule to the entire surface and 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 for dividing the pressure-sensitive printing portion on the front surface of the plastic cover film 1 as described above, the 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 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 the writability can be imparted. Due to this laminated structure, when the computer output is written on the copy paper 11 on which the form is printed in advance by using the ink tape, the upper half of the computer output is displayed on the plastic cover film 1. Is printed on the plastic cover film 1, but the computer output corresponding to the lower half is not printed 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 side of the copy sheet 11 of the continuous laminated sheet, the cutout line 12 is used. The laminated sheets 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 this embodiment, the copy sheet 11 is not adhered to the lower layer in the periphery, and therefore the copy sheet 1 is cut off.
1 is released from the lower layer. This can be saved as a copy sheet. Before cutting this copy sheet,
The three sheets are adhered and fixed by the edge papers 13 on both sides.
When the computer output is continuously printed on the continuous output paper of this embodiment and the print card portion is cut off by perforations, the copy paper 11 is released,
After that, the same two-layer laminated sheet as described after printing by computer output in the case of Example 1 is obtained. Since the print card 2 is a thick plastic sheet, heat sealing can be used for the sealing portion around the rectangular shape. Print card 2 like this
If a plastic sheet is used for the waterproof property and confidentiality will be perfect. 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. Are two sheets fixed at the upper side, and the printed contents can be read simply by flipping the cover film toward the upper edge, which is convenient.

EFFECTS OF THE INVENTION The communication printing laminated sheet of the present invention cannot be restored once it is opened during communication, so it can be identified that it has been opened. be able to. Also,
Since both sides are plastic sheets, the printed surface can be prevented from bleeding in rainwater, etc. Furthermore, the surroundings of the two laminated layers can be easily and completely sealed by heat, and the flexible plastic Since pressure-sensitive printing is performed through the 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, so that the contents can be written on the internal printing card from the outside of the sealing sheet according to the type of computer output. can do. Furthermore, if a copy sheet is used and type-printed, it is possible to selectively write only the upper half part of the address etc. when copying on the lower plastic film. . In this case, it is convenient that printing can be performed using ink in both upper and lower parts.
