接着紙に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to rewetting adhesive paper for printers. More specifically, the present invention relates to rewetting adhesive paper with improved runnability in a printer.

のである。 However, such non-impact type printers usually form an electrical latent image on a drum whose surface has been treated with selenium or the like, and then form the image on paper through a process of development, transfer, and fixing. It is.

のため従来の再湿接着紙はプリンターに通紙する
ことができないことから、プリンターに通紙可能
な再湿接着紙の開発が強く要請されて来た。 Conventionally known rewetting adhesive paper generally contains glue, gelatin, gum arabic, dextrin, polyvinyl alcohol, modified starch, polyvinyl acetate,
Since this type of rewetting adhesive paper is made by dissolving or emulsifying a synthetic or natural water-soluble adhesive, such as acrylic, in water and applying it uniformly to the paper surface, when it is passed through a printer, the printer Paper running becomes virtually impossible due to glue adhering to the inner heating plate or heat roll, or curling caused by heating (hereinafter referred to as heat curl). Since paper cannot be passed through the printer, there has been a strong demand for the development of rewetting adhesive paper that can be passed through the printer.
従来公知の再湿接着紙の使用がプリンター内で
走行不良となる主因は、前記したように再湿接着
紙の糊剤が熱板またはヒートロールへ付着するこ
とと、該接着紙のヒートカールとによるものであ
るが、かゝる現象については次のように理解する
ことができる。 The main causes of poor running in the printer when using conventionally known rewet adhesive paper are the adhesion of the glue in the rewet adhesive paper to the hot plate or heat roll, and the heat curl of the adhesive paper, as described above. However, such a phenomenon can be understood as follows.

状態にさらされて糊剤が活性化し、付着する湿熱
付着の２つの場合がある。 In other words, the former is a synthetic polymer rewetting adhesive with a melting point of 70°C or less, such as vinyl acetate polymer,
In the case of a resin such as an acrylic polymer, the resin may be melted by heating with a hot plate or a heat roll and adhere to the hot plate or heat roll, or a polymeric material with a high melting point such as polyvinyl alcohol. There are two cases of wet heat adhesion, in which the adhesive is activated and adheres when exposed to high humidity and high heat conditions.
しかしてそれら２者はいずれも再湿接着剤に熱
的条件が関与するものであるから、融点と密接な
関係を有し、このため融点が70℃以下の再湿性樹
脂は、ノンインパクトタイプのプリンターに適用

ある。 However, since both of these are related to thermal conditions in rewetting adhesives, they have a close relationship with the melting point, and therefore rewetting resins with a melting point of 70°C or less are non-impact type. It is practically impossible to apply this method to rewetting adhesive paper used in printers.

に活性化して湿熱付着性の発現により、これが熱
板またはヒートロールへの付着の原因となる。 From this point of view, in an attempt to prevent the polymers, which are rewetting resins with a low melting point, from adhering to the hot plate when used alone, it is conceivable to mix the polymers with an anti-adhesion agent during heating. Mixing of such anti-adhesive agents results in a loss of rewet adhesion, making it impossible to expect the desired rewet adhesion effect. For this reason, the melting point of the rewetting adhesive for rewetting adhesive paper that should be applied to electrophotographic printers must be 70°C or higher, but generally synthetic polymer rewetting adhesives that are activated by moisture are used. As mentioned above, has the property of being activated in high humidity and high temperature conditions, so when general paper is passed through a printer, for example, the paper is heated by a heater and the moisture in the paper evaporates. As a result, the atmosphere inside the printer tends to be high humidity and heat. Therefore, the melting point in such an atmosphere
When coated paper coated with a synthetic polymeric rewetting adhesive at a temperature of 70°C or higher passes through, the rewetting adhesive is easily activated and develops wet heat adhesion, causing it to be transferred to the hot plate or heat roll. may cause adhesion.

It is caused by the shrinkage of the surface. For this reason, such heat curls can be detected by the wind pressure sensor that detects flapping paper in the printer and stops the machine, and can even cause the printer to fold the paper after it is ejected (after forming the paper). This results in difficulty in folding and stacking sheets of paper.

完成した。 In view of the above points, the present inventors have conducted various studies and found that a synthetic polymer rewetting adhesive with a melting point of 70°C or higher has been developed.
A coating liquid containing chemicals (hereinafter referred to as a moist heat adhesion prevention agent) that can prevent moist heat from adhering to the hot plate or heat roll in the printer is applied to the support paper, and the resulting rewet adhesive paper is passed through the printer. The object of the present invention has been achieved by discovering that it is possible to effectively prevent wet heat adhesion of paper to a hot plate or heat roll when paper is rolled. At the same time, when it is necessary to prevent heat curl inside the printer, a chemical that can slow down the evaporation rate of water (hereinafter referred to as a heat curl control agent) is added to the coating solution to prevent heat curl. The present invention was completed by discovering that a desirable rewet adhesive paper for printers can be obtained.

組み合わせ使用することも可能である。 However, when using the inorganic pigment as a wet heat adhesion inhibitor, the inorganic pigment can be added to the rewetting adhesive 100%
It is added at a mixing ratio of 10 parts to 500 parts, preferably 20 parts to 200 parts. This compounding amount is 10% for rewetting adhesive.
If the amount is less than 50 parts, the moist heat adhesion prevention effect will not be sufficient, and if it is more than 500 parts, the rewetting adhesive property will be lost, making it unsuitable. When using waxes, metal soaps, fatty acids, etc. as moist heat adhesion inhibitors,
It is added in an amount of 0.1 to 20 parts, preferably 1 to 5 parts, per 100 parts of the rewetting adhesive. If the amount added is less than 0.1 part of the rewetting adhesive, the moist heat adhesion prevention effect will not be sufficient, and if it is more than 20 parts, the rewet adhesive property will be lost, which is unsuitable. In the above, it is also possible to use a combination of inorganic pigments, waxes, metal soaps, fatty acids, etc.

If the amount added is less than 1 part to the rewetting adhesive, the effect as a heat curl control agent will be poor, and if it is more than 200 parts, it will cause deterioration of the rewet adhesion and the occurrence of heat curl on the printed surface. It is not appropriate.

がよい。 In this way, in the present invention, the amount of coating liquid applied to the supporting paper is always one of the major factors that determines the quality, and the amount of coating liquid applied to the supporting paper is 0.5
If it is less than g/m 2 , good results can be obtained with respect to moist heat adhesion and heat curling property without any problems, but rewet adhesion, which is an important quality, disappears.
Furthermore, if the coating amount of the coating liquid is 30 g/ m2 or more, not only can it not be expected to improve quality such as rewetting adhesion by increasing the coating amount, but also increasing the coating amount is disadvantageous from an economic point of view. be. Therefore, the amount of the coating liquid applied to the support paper of the present invention is preferably in the range of 0.5 g/m 2 to 30 g/m 2 , preferably 2 g/m 2 to 10 g/m 2 .

配慮が湿式プリンター用以上に必要となる。 When the thus obtained rewetting adhesive paper for printers of the present invention is applied to a printer, the adhesive paper has good runnability within the printer. There are two types of electrophotographic printers depending on the development method: dry type and wet type (liquid dry type).
In the dry type, the temperature of the hot plate is usually higher than in the wet type because the toner is thermally fixed. This temperature difference affects the runnability of the paper within the printer, and for dry printers it is necessary to pay more attention to moisture and heat adhesion than for wet printers.
