Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a recording sheet,
In particular, the pseudo-adhesiveness of the adhesive layer can be applied to various information printing methods, and the fluctuation of the adhesive force after printing is small,
The present invention relates to an information recording sheet that does not cause blocking and has a pressure-sensitive pseudo adhesive property.

[0002]

2. Description of the Related Art Conventionally, various kinds of information that need to be concealed or concealed are printed on a recording sheet provided with a layer having a pseudo-adhesive property, and then the layers are opposed to each other and pressed to be pseudo-adhered. Has been used as an information hiding sheet that can be peeled off when necessary, and has been put to practical use as a communication medium centered on confidential postcards. Particularly in recent years, attention has been paid to the pseudo adhesive property and the ease of a processing method using the pseudo adhesive property, and it has begun to be used also as an overlay form such as delivery slip paper.

Usually, the pseudo-adhesive layer provided on these pressure-sensitive pseudo-adhesive sheets mainly contains natural rubber having a low glass transition point or synthetic rubber mixed with various tackifiers as an adhesive. In this case, the mechanism of the adhesive force development of the pseudo adhesive layer was considered to be exclusively the self-diffusion of the polymer adhesive at the adhesive layer interface (Adhesion Technology, 15 (2), pp. 49-53, 1995. Year) . Therefore, the adhesive as a constituent material is required to have self-adhesiveness or tackiness.

However, the coated sheet provided with the pseudo-adhesive layer is, for example, a contact surface when the sheet is rolled up, or a perforation or a punch when the sheet is folded into a Z shape. There is a drawback in that blocking occurs on the surface of the pseudo adhesive layer of the holes, and an accident such as inability to feed paper occurs during printing or molding. Therefore, masking processing by printing is performed on the perforations and the like (Japanese Patent Laid-Open No. 2-2893).
No. 93, etc.) and a deterioration treatment (Japanese Patent Laid-Open No. 5-116488, etc.).

As an adhesive, an adhesive composition prepared by filling a pressure-sensitive adhesive that does not adhere in a normal state with fine particles that are not thermoplastic or mixing it as a buffer (Japanese Patent Laid-Open No. 1-85794). No. 1-168779, etc.) has also been proposed. However, since a pressure-sensitive adhesive that does not adhere in a normal state is used, it is necessary to perform pressure bonding or high temperature under a heavy load for a long time in order to bond the coated sheet. In addition to being impractical, there is a drawback that only non-thermoplastic fine particles can be used when a high temperature is applied.

Further, in recent years, as a method of recording information on a pseudo-adhesive layer, for example, a ground pattern or a fixed form information is recorded by an offset printing machine or the like, and individual variable information is linked with an electronic computer. With the increased flexibility of recording methods such as printing with high-speed non-impact printers such as inkjet method or inkjet method, the pseudo-adhesive sheet is used not only as a highly confidential communication medium, but also as a direct method using envelopes. Even for email, it has come to be used as an inexpensive communication means that can be processed quickly.

However, in offset printing or the like, an ultraviolet lamp is used for fixing ink, while in non-impact printing by high-speed electrophotography, fixing of printing is mainly performed by a high temperature heating method of about 160 to 220 ° C. Therefore, there is a problem in that the pseudo adhesive layer is oxidatively deteriorated by an ultraviolet lamp or is deteriorated by heat.

Particularly, in the adhesive composition having self-adhesiveness or tackiness which has been often used conventionally, as an adhesive, for example, natural rubber, modified natural rubber, styrene / butadiene rubber, nitrile rubber, vinyl acetate rubber, etc. In addition to the above, the composition is based on a mixture of fine particles having no thermoplasticity for the purpose of suppressing blocking and the like at the time of processing the above-mentioned sheet to be coated, and therefore is susceptible to oxidative deterioration and thermal deterioration by ultraviolet rays. When the resin functioning as an adhesive is deteriorated in this way, its viscoelasticity becomes poor, resulting in an adhesive composition that loses its self-adhesiveness or tackiness.

Therefore, when various recording methods are used in order to cope with the diversification of the above-mentioned usage forms, even a pressure-sensitive adhesive recording sheet designed to have the same adhesive force is printed by an offset printing machine. When using only with an electrophotographic printer or inkjet printer, and
When these are used in combination, since the degree of deterioration of the adhesive is different, the adhesive strength of the recording sheet at the time of pseudo-adhesion is different.

Therefore, irrespective of the information recording method, when pseudo-bonding is performed under the same conditions, the adhesive force is sometimes too low to spontaneously peel during transportation, and sometimes the adhesive force is too high to be re-peeled. In some cases, the information cannot be read and the information recorded on the pseudo adhesive surface cannot be read due to tearing. Therefore, the user is forced to perform a very complicated work of individually adjusting the pressure condition for adhering the recording sheet according to the recording method of the recording sheet to obtain an appropriate adhesive force. Is.

[0011]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is that it does not cause blocking and has excellent printability, and even if it is printed by any method, the fluctuation of the adhesive force due to printing is small and it is always stable. Another object of the present invention is to provide a recording sheet having the above pseudo adhesive force.

[0012]

SUMMARY OF THE INVENTION The above objects of the present invention are as follows.
The pseudo adhesive strength is 10 to 350 gf / i, which is obtained by applying a pseudo adhesive adhesive composition containing a thermoplastic adhesive and fine particles as main components to at least a part of the substrate surface.
n. Which is a recording sheet for communication or delivery,
The layer formed by applying the adhesive composition is a layer in which the amount of change in the pseudo adhesive strength is within ± 30% before and after printing on the layer with a printing machine and / or a printer. And a pressure-sensitive pseudo-adhesive recording sheet.

The base material used in the present invention can be appropriately selected from known materials. Specific examples thereof include high-quality paper, medium-quality paper, synthetic paper, polyethylene film,
Examples thereof include polyethylene terephthalate film, film-bonded paper, coated paper, laminated paper, and metallized paper.

In the present invention, the pseudo adhesive strength (hereinafter simply referred to as adhesive strength) before information printing is performed between two metal rolls under the same environment after sufficiently controlling the humidity in an environment of 20 ° C. and 65% RH. Using a pressurizer of the type that allows
T after 2 hours after bonding at kg / cm and 10 m / min
Peeling test result is 10-35 at peeling speed 300 mm / min
0 gf / in. And the sample at 20 ° C, 6
It is necessary that no blocking occurs even when a pressure of 25 kgf / cm ² is applied in an environment of 5% RH.

The adhesive strength before information printing is 10 gf / in. If it is less than the above range, there is a risk that the pseudo adhesive surface may be peeled off during transportation when the adhesive force is reduced after printing. Adhesive force is 350gf
/ In. If the adhesive strength increases after printing, the paper layer peeling will occur instead of peeling between the pseudo-bonding surfaces when paper is used as the support of the recording sheet, making it impossible to obtain information. .

The thermoplastic adhesive used in the present invention is an acrylic resin having a glass transition point of −55 to 15 ° C.,
A vinyl acetate resin, a vinyl chloride resin, a vinylidene chloride resin, or a synthetic rubber such as acrylonitrile-butadiene rubber or styrene-butadiene rubber can be appropriately selected and used. These thermoplastic adhesives may be used alone or in combination of two or more kinds.
In the present invention, it is particularly preferable to use a self-crosslinking acrylic resin.

In the present invention, in order to develop the adhesive force between the coating layers, a mechanical adhesion mechanism by the anchoring effect between the layers based on the fine irregularities on the surface is used. Therefore, the formation of fine irregularities on the surface, which holds the key to the anchoring effect, is adjusted by adding fine particles to the adhesive composition. The fine particles referred to herein can be appropriately selected from known ones as described below, but in the present invention, it is preferable to contain at least non-thermoplastic fine particles.

The average particle size of the fine particles used in the present invention is preferably in the range of 0.5 to 4 μm. If the average particle size is less than 0.5 μm, sufficient adhesive force is not exhibited, and if it exceeds 4 μm, fine particles are easily peeled off from the coating layer, which adversely affects adhesion. In addition, the average particle diameter usually indicates the average value of the size of one particle, but, for example, fine particles such as silica form a group and behave as if they were one particle. When indicated, it means the average size of this population (secondary particles).

In the present invention, in order to suppress the difference in adhesive force between before and after printing by a printing machine and / or a printer within ± 30%, it is necessary to have a spherical shape surrounded by a curved surface, a spindle shape, a disk shape, a cylinder, a polygonal prism, a polygon. This can be easily performed by adjusting the addition amount of particles having a shape such as a weight and having an average particle diameter of 8 to 25 μm. In this way, it is possible to delicately control the adhesive force of the coating layer itself by controlling the three-dimensional structure of the adhesive coating layer surface by using appropriate fine particle groups having different average particle diameters. at the same time,
It is possible to produce a recording sheet which has excellent printability and also has an effect of preventing blocking.

The fine particles used in the adhesive composition of the present invention include silica, kaolin, clay, calcium carbonate, aluminum hydroxide, zinc oxide, titanium oxide, starch particles, cellulose fine powder, and melamine resin particles. , Urea-based resin particles, styrene-based resin particles, acrylic resin particles, regenerated nylon particles, vinyl chloride, polyethylene, and polycarbonate, etc. are used by appropriately selecting from known inorganic or organic fine particles. be able to. These microparticles can be used alone,
Two or more kinds may be used in combination.

In the adhesive composition for forming the coating layer in the present invention, if necessary, an antistatic agent, a surfactant, a defoaming agent, a dispersant, an antiseptic agent, a thickener, and a wetting agent. Further, auxiliary agents such as an ultraviolet absorber, an antioxidant, a fluorescent dye, a colored dye, a dye fixing agent, a mordant, and an ink fixing agent can be added.

The coating amount of the adhesive composition in the recording sheet of the present invention is usually 2.5 to 10 g / m ² (dry weight).
It is. If it is less than 2.5 g / m ² , the adhesiveness is not sufficiently exhibited, and if it exceeds 10 g / m ² , the adhesive force is too high and re-peeling becomes difficult and the substrate may be damaged. or,
The adhesive composition can be applied to the substrate by a known application method such as an air knife coater, a blade coater, a bar coater, a roll coater, a curtain coater, a squeeze coater, a kiss coater, a comma coater or a gravure coater.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION The recording sheet of the present invention comprises a thermoplastic adhesive and fine particles so that the amount of change in adhesive force before and after printing by a printing machine and / or printer is within ± 30%. It can be easily obtained by preparing a pseudo adhesive composition and applying the obtained composition to at least a part of the substrate surface by a known method.

[0024]

EFFECTS OF THE INVENTION The recording sheet of the present invention has a small fluctuation in the adhesive force due to printing regardless of the printing method used, so that the recording sheet is always stable even if the adhesive conditions are not selected according to the printing method. It is possible to obtain the above pseudo adhesive strength, and it is useful for quickly and stably processing a large amount of communication and contact work.
