Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a printed card with a concealment cover, and particularly relates to a printed card with a concealment cover in which a removable concealment sheet is provided on the card writing surface.

(Prior Art) In order to temporarily hide a specific information field on the written side of a card-like product such as a postcard, for example, a concealing sheet is applied to the information field to be hidden using a pressure-sensitive adhesive via a release treatment layer. (Utility Model Publication No. 55-36858)
etc. are known, but in this case, it is not necessarily easy to peel off the concealing sheet as necessary, and there are practical problems in that smoothness and reliability are lacking.

In order to eliminate such drawbacks, the present applicant has proposed various labels or cards in which a transparent protective film is adhered to the writing surface to be concealed, and a concealing sheet is releasably bonded to this protective film by heat bonding. (For example, Jitsugan Sho 60-99277
No. etc.). In these cards, when the concealing sheet is peeled off, the bonding layer of thermoplastic resin supplied and solidified by hot extrusion or the like between the concealing sheet and the protective film is reliably peeled off from the protective film side, and the mount surface is The description can be read through the protective film.

However, when an end user uses such a card, it is necessary to print predetermined information on the surface of each card in advance and then adhere the laminate including the protective film and cover sheet to the card surface. For example, if such technology is applied to a large number of postcard shipping processes that are automated using computer printing methods, gluing and pasting processes will be introduced during line work, making the entire work process complicated. become

Therefore, there is a need for a card in which the writing surface is basically hidden by a cover sheet, and which does not require the user to carry out this concealing process.

(Means for Solving the Problems) The problem with the above-mentioned prior art is a card mount having a self-coloring layer on at least a portion of its surface, and a concealing material adhered to the mount via a transparent pressure-sensitive adhesive layer. a laminate, wherein the laminate between the concealers is a protective film made of a transparent thermoplastic synthetic resin, and a covering sheet with concealing properties having a laminate layer made of a thermoplastic synthetic resin on one surface; A thermoplastic synthetic resin made of a material similar to the thermoplastic resin of either the protective film or the laminate layer, and supplied in a molten state between the protective film and the laminate layer at a temperature at least above its softening point and solidified. and a bonding layer consisting of a cover sheet having a concealing property, and color printing is applied to the self-coloring layer of the card mount by pressure printing from the covering sheet side of the laminate having a concealing property. The solution is a printed card with a cover.

(Function) In the printed card with a concealment cover of the present invention,
For example, if a laminate is applied to a card mount for a postcard or the like, and if printing is done in advance using a dot printer or the like from the cover sheet side on the surface, the self-coloring layer on the mount will be colored under pressure through the laminate. Ru. Here, between the protective film made of a transparent thermoplastic synthetic resin that is adhered to the mount, a laminate layer of a covering sheet with concealing properties is placed between them, and a thermoplastic resin provided by hot extrusion etc. They are bonded with a predetermined peel strength through a bonding layer made of resin, and for example, if this bonding layer is made of a thermoplastic resin of the same type as the laminate layer, this bonding layer protects when the covering sheet is peeled off. It peels off from the film side and transfers to the laminate layer side. Therefore, the protective film remains adhered to the surface of the card mount, through which the color printing of the self-coloring layer on the card mount can be read.

In this way, in the present invention, the self-coloring layer on the card backing surface is hidden by the laminate, so the user can print the desired color using a regular dot printer from the front side of the completed card. Hidden printing is performed, and the work such as printing on the card surface and then pasting the laminate is omitted.

Hereinafter, the present invention will be explained in detail with reference to specific examples.

Embodiment 1 FIG. 1 is a longitudinal cross-sectional view of a postcard card incorporating a pressure-sensitive color printing surface to which the present invention is applied, and FIG. 2 is an explanatory view showing its usage mode.

In Fig. 1, one side (for example, the back side of the postcard) of a postcard mount 1 as a card mount is colored by the well-known self-coloring reaction of a coloring agent released by the destruction of the capsule when pressurized. Layer 2 is applied over almost its entire surface. Furthermore, a concealing laminate 4, which will be described later, is firmly adhered to the self-coloring layer 2 via a transparent pressure-sensitive adhesive layer 3.

This laminate 4 includes a transparent protective film 5 made of polyethylene terephthalate (PET) with a thickness of approximately 25 μm that closely protects the self-coloring layer 2 in a transparent manner;
A polyethylene layer 7 as a laminate layer is integrally applied to the back side by heat extrusion and is concealed by aluminum vapor deposition (not shown) to a thickness of approximately
It consists of a covering sheet 6 made of 50 μm high-quality paper and a polyethylene layer 8 as a bonding layer which is supplied in a molten state between the protective film 5 and the polyethylene layer 7 and solidified.

When manufacturing the laminate 4, a polyethylene resin with a thickness of about 20 μm is formed by melting and supplying polyethylene resin at a temperature of about 325° C. to the back side of a high-quality covering paper 6 that has been subjected to a concealing treatment. The laminate layer 7 is firmly fixed.

Next, a polyethylene resin of the same type as the polyethylene of the layer 7 is supplied between the polyethylene layer 7 and the PET protective film 5 by hot extrusion at a temperature of about 310°C, and is sandwiched between cooling rolls (not shown). It is compacted to form a polyethylene layer 8 for bonding. During the cold compression bonding, this polyethylene layer 8 is completely integrally bonded to the polyethylene layer 7 made of the same type of material due to partial compatibility occurring at the interface between them. On the other hand, it is made of different materials.
The polyethylene resin, which has become fluid due to melting, gradually enters the PET protective film 5 along the minute irregularities on the film surface, and after solidifying under pressure between cooling rolls, it is peeled off with a predetermined peel strength. Combine as possible. The thus formed concealing laminate 4 is then applied to the postcard mount 1 as described above.
The self-coloring layer 2 applied to the upper surface of the postcard is firmly adhered to the self-coloring layer 2 through a transparent acrylic pressure-sensitive adhesive layer 3 to form a postcard with a hidden writing surface.

Predetermined information is stamped (blank stamped) on the thus formed postcard from the upper surface side of the cover sheet 6 of the laminate 4 using a wire dot printer (not shown) without using a printing ribbon.

Here, the printing pressure of the printer head is applied to the self-coloring layer 2 through the laminate 4, so the coloring agent capsules in the self-coloring layer 2 are destroyed and a coloring reaction occurs, resulting in color development as per the predetermined printing. Color printing is performed on the postcard mount 1.

This colored state is always hidden from the outside because the postcard mount 1 is covered with a laminate 4, especially a covering sheet 6 that has been subjected to a concealing treatment, and the printing is due to blank printing of the printer head. Naturally, it does not appear on the surface of the covering sheet 6.

The postcards printed in this way are delivered to the recipient after normal sorting, shipping, and delivery work, but since the laminate 4 is firmly adhered to the postcard mount 1, the laminate 4 may slip off. To surely cover and protect the writing surface of a postcard without causing peeling or peeling.

Regarding the interlayers of the laminate 4, the high-quality covering paper 6 and the polyethylene layer 7 are bonded by ordinary laminate, and the polyethylene layer 7 and the polyethylene layer 8 are bonded by a phase of the same type of resin as described above. They are firmly fixed to each other by a molten piece. Furthermore, the polyethylene layer 8 and the PET protective film 5 are bonded by wetting the minute irregularities on the PET surface during hot extrusion of the polyethylene resin and solidifying by cooling, so that they do not easily come apart or peel during normal handling. Fixed. Here, if the peripheral edge 9 of the laminate 4 is heat-sealed, the integrity between the layers 5, 6, 7, and 8 will be more secure.

When the recipient of the postcard wants to read the contents, the heat-sealed portion of the lower edge 9 of the cover sheet 6 is cut off along the cut-off line 10 displayed inside the peripheral edge 9 of the cover sheet 6, and then peeled off using silicone or the like. The laminate 4 is peeled off from the peeled end portion 10A which has been previously applied. Here, depending on the bond strength between each layer of the laminate 4 and the strength of the adhesive strength to the postcard mount 1,
Peeling always occurs between the polyethylene layer 8 and the PET film 5, which have a weak bonding force, and each layer 6, 7, and 8 in the laminate is integrated with the PET film 5 remaining on the postcard mount 1. Peeled off.

Therefore, the recipient can print the description printed on the self-coloring layer 2 on the top surface of the postcard mount 1 on a transparent sheet.
It can be read through PET film 5.

According to the embodiment described above, the postcard mount 1 is supplied to the user with the concealing laminate 4 adhered to its upper surface in advance, and the user simply applies pressure printing from the cover sheet 6 side of the laminate 4. Since the colored print hidden by the laminate 4 can be obtained on the upper surface of the postcard mount 1 by simply pressing the paper, there is no need for the conventional trouble of gluing a concealing sheet after printing on the postcard.

In addition, the color printing part is used as a transparent protective film.
Since it is covered with the PET film 5, the colored printing surface will not be faded or smudged due to abrasion due to various handling even after the covering sheet is removed.

Embodiment 2 FIG. 3 is a plan view of the main parts of an embodiment in which the present invention is applied to a postcard with a multilayer structure.

For business postcards, etc., where a large number of sheets are processed, computer-processed information is continuously printed on the writing surface using a printer, so for example, a mount (roll paper) 11 whose size is approximately twice the width of the postcard is used. is used as a postcard base paper, and 1/2 of the left and right areas are used as the front and back sides 11A and 11B of the postcard, respectively, to simultaneously print necessary information such as the addressee and correspondence using a line printer. Are known.

For example, such a roll paper 11 is sent out in synchronization with a predetermined printing speed of the printer by engaging the perforations 19 on both sides with engagement protrusions on a platen (not shown) of a line printer, and printing individual postcards. After simultaneously printing on the front and back sides 11A and 11B in the area corresponding to , the roll paper 11 discharged from the printer is cut into individual postcards, and the front and back sides 11A and
By folding 1B along the center line 20 and integrating them with an adhesive pre-applied to the back side, a structurally two-layer multilayer postcard is obtained.

In this embodiment, as shown in FIG. 4, a self-coloring layer 12 is applied in advance to a region corresponding to, for example, the back surface 11A of the postcard base paper 11, and a transparent acrylic adhesive layer 13 is applied to the upper surface of the self-coloring layer 12. A laminate 14 having the same structure as 1 (PET film 15, covering sheet 16, polyethylene laminate layer 1)
7. Adhere the polyethylene bonding layer 18).

Front and back surfaces 11A, 11 of such a postcard base paper 11
When printing is performed on B using a printer, the front and back surfaces 11A and 11B are simultaneously printed using a dot printer or the like while the surface of the back surface 11A is covered with dummy paper 21. In this case, the print head of the printer is combined with a regular printing ribbon, and the surface 1
Address printing and the like for 1B are performed directly on this paper surface using ribbon ink. On the other hand, the back side 11A
Regarding the description, the actual printing by the ribbon appears on the dummy paper 21, and only the printing pressure of the printer head is applied to the laminate 14. This printing pressure is applied to the self-coloring layer 12 on the back side 11A through the laminate 14 to perform coloring printing, but in this coloring printing, as in the case of Embodiment 1, the recipient holds the cover sheet 16 etc. Only when it is peeled off can the transparent PET film 15 left on the back surface 11A be seen through.

In this embodiment, since the front and back sides 11A and 11B are simultaneously printed using a printer head equipped with a printing ribbon, a dummy paper 2 is placed on the back side 11A.
1 is used, but instead of this, the printing ribbon is used only when printing on the front side 11B side with the printer head, and when printing on the back side 11A side, the ribbon is removed from the stamping area and blank printing is performed. A mechanism may also be used.

Further, the self-coloring layer 12 is attached to the front and back surfaces 11A,
11B, it is also possible to perform color printing on both sides simply by blank printing with the printer head. However, in this case, in order to prevent the self-coloring layer 12 on the surface 11B from developing color and staining due to external pressure such as rubbing other than printing, only the protective PET film 15 in the laminate 14 is coated as shown in FIG. It is preferable to provide it also on the surface 11B side.

Note that the entire laminate 14 has both front and back surfaces 11A and 11B.
It is also preferable in terms of the manufacturing process to form the layers over several layers, but in this case, the weight of the entire postcard base paper increases, so it is necessary to make the thickness of each layer sufficiently small.

(Effects of the Invention) As described above, according to the present invention, cards such as postcards whose writing surface is covered with a removable cover can be extremely easily handled by the user.
