認できる。2. Description of the Related Art In recent years, applications of two-fold and three-fold postcards using pressure-sensitive recording paper have been expanding. These pressure-sensitive recording papers are formed by applying a pressure-sensitive adhesive coating solution that shows neither adhesiveness nor adhesiveness in a normal state and exhibits adhesiveness when pressed on a support to form a pressure-sensitive adhesive layer. The pressure bonding layers are bonded by pressure in a state where the pressure bonding layers face each other. The bonding at the time of pressing can be peelable after bonding, or can be bonded to the point where it cannot be peeled. The contents of the confidential communication of the postcard (password, member number, billing amount, balance of deposit, etc.) can be printed on the peelable pressure-sensitive adhesive surface, pasted by pressure, and then confirmed by the recipient being peeled off.

題が生じていた。[0003] Such a pressure-sensitive recording paper must be able to be peeled off without destruction or contamination of the bonded surface and the printed content. It is a general configuration that particles such as pigment and starch are dispersed therein. However, due to the pigment or starch, the strength of the pressure-sensitive adhesive layer has been reduced, causing problems such as falling off of the coating layer from the support and poor printing durability during printing.

など）がとられているプリンタの総称である。Further, such a pressure-sensitive recording paper is printed on a pressure-sensitive adhesive layer, bonded to another pressure-sensitive adhesive layer by pressing, and peeled off again to confirm the contents.
There is a problem of so-called show-through or ink transfer, in which the printed content is transferred to the facing pressure-sensitive adhesive layer. In order to avoid such a show-through phenomenon, a printing method using a non-impact printer has been adopted. Here, a non-impact printer means that after printing, ink (or toner)
Is a generic term for printers that employ a printing method (e.g., electrophotography, laser printer, etc.) for fixing the image with heat.

った。[0005] However, despite the use of the non-impact method for the purpose of preventing show-through, such a heat fixing method gives excessive heat to the printing surface (pressure-sensitive adhesive surface) and the paper itself, Because it deprives the water and the pressure-sensitive adhesive surface dries and the pressure-bonding property deteriorates, it is necessary to apply strong pressure for proper bonding. There have been problems such as that the printed contents show through due to a decrease in the strength of the layer and that the fixing roll of the printer is stained.

い。The above-mentioned pressure-sensitive adhesive is developed by the self-adhesion of a polymer, especially a natural rubber component or a modified component thereof. The pressure-sensitive recording paper of the present invention has a self-adhesive property. In addition, characteristics that do not exhibit tackiness on the surface are required. When the surface shows tackiness, it cannot be used because workability in handling is remarkably reduced, such as occurrence of blocking. As the base polymer of the pressure-sensitive adhesive satisfying these properties, natural rubber or a modified product thereof (hereinafter, both are referred to as (modified) natural rubber) are in the form of a solution or emulsion, or (modified) natural rubber. A copolymer obtained by copolymerizing a rubber component with a (meth) acrylate at a ratio of 50% or more is suitable. It is not preferable to use a base polymer containing a synthetic rubber as a main component in the present invention because the surface of the base polymer exhibits adhesiveness even after coating and drying.

が格段に向上した。As an essential component of the present invention, thermoplastic particles are used in combination for the purpose of controlling the adhesiveness of the pressure-sensitive adhesive layer. In general, a thermoplastic material exhibits plasticity with increasing temperature, enables molding, and undergoes a reversible change that returns to its original state when the temperature decreases, but does not cause any chemical change such as molecular structure during that time There are features. Furthermore, it was unexpected at the beginning that by using thermoplastic particles for the pressure-sensitive adhesive layer, not only can the adhesiveness of the pressure-sensitive recording paper be controlled, but also the winding form and the stock form can be used. When handling this pressure bonding recording paper as
The handling property has been remarkably improved, for example, blocking (a phenomenon in which the pressure-bonded recording papers adhere to each other to deteriorate the paper feeding) hardly occurs.

い。Further, in the pressure-sensitive recording paper of the present invention,
When the pressure-sensitive adhesive layer is provided on the support, the plasticity of the thermoplastic particles is developed by heating and drying using a dryer or the like to remove unnecessary moisture immediately after the application of the pressure-sensitive adhesive layer. For this reason, the bond between the coating layer and the support is strengthened, and the film strength of the pressure-sensitive adhesive layer is improved, so that the printability is remarkably improved, and the pressure-sensitive adhesive layer or a part thereof is removed by a printing machine. It has been found that there is no more accident that could happen. In addition, compared to the case without thermoplastic particles,
It has been found that the smoothness of the surface of the coating layer is improved and the finish of printing is improved. On the other hand, thermosetting substances
Because the crosslinking reaction proceeds by heating, the physical properties before and after the heating are different, which makes it difficult to control the adhesive force, which is the original purpose, and causes adverse effects such as lowering the strength of the coating layer itself. Therefore, it is not preferable to use in the present invention.

の向上が達成できることが明らかとなった。Further, by subjecting the pressure-sensitive recording sheet of the present invention to a heat treatment within the range from the softening point to the melting point of the thermoplastic particles, the bond between the pressure-sensitive adhesive layer and the support becomes strong,
In addition, it has been clarified that the surface smoothness can be improved and the printability and the handleability can be improved.

接着不良などのトラブルを発生させる原因になる。The thermoplastic particles used in the present invention preferably have an average particle size of 1 to 30 μm. If the average particle size is less than 1 μm, it is difficult to control the adhesive force of the adhesive, and problems such as blocking and re-peeling are likely to occur, which is not preferable. On the other hand, if the average particle size is larger than 30 μm, the effect of suppressing the adhesive force of the adhesive becomes too large, which causes troubles such as poor adhesion.

ていた。Evaluation result: The pressure-sensitive recording paper obtained in the examples was excellent in suitability for an offset rotary web printing press,
It is possible to continuously print a large amount without soiling the printing press. Further, it is suitable for non-impact printing and can perform printing excellent in toner fixing without soiling the printer. Furthermore, the adhesive force could be appropriately controlled with respect to the pressure bonding property, and the internal print record after re-peeling did not show off to the opposite face.

った。On the other hand, the pressure-sensitive recording paper of the comparative example cannot achieve both control of the adhesive force and printability or suitability for non-impact printing. In particular, when particles having no thermoplasticity are blended, powder drops from the pressure-sensitive adhesive layer are observed, and a large amount of stain is generated during printing and non-impact printing. In addition, even when particles having thermoplasticity are blended, if the average particle diameter of the particles is out of the range of 1 to 30 μm, it becomes difficult to control the printability and the adhesive force,
It was difficult to use as confidential recording paper.
