が利用されている。(Prior Art) As a method of using a pressure-sensitive recording sheet utilizing the reaction between an electron-donating color former and an electron-accepting color developer, an optical reading paper and a pressure-sensitive recording sheet are set, and a writing or type marking is applied to the set. The optical reading paper on the upper side is processed by an electronic computer by an optical reading device, and the pressure-sensitive recording sheet on the lower side is a set form for general paper processing.

感圧記録用帳票がある。In this case, as a set form of the optical reading paper and the pressure-sensitive recording sheet, one is the optical reading paper as it is and the self-coloring type pressure-sensitive recording sheet is spot-bonded or line-bonded with an adhesive. There is a pressure-sensitive recording form that is adhered, and the other is an optical reading paper having a coating layer of microcapsules containing oil droplets in which an electron-donating color former is dissolved and an electron-accepting developer. There is a pressure-sensitive recording form formed by spot-bonding or line-bonding a sheet having a layer with an adhesive.

起こすことになる。These forms will not be separated from each other until they are written or type-printed and used for paperwork, and when they are separated, they are optically passed from an optical reading device. Ideally, the adhesive can be separated without the adhesive remaining on the paper surface or picking on the paper surface. However, there is a problem in that even if spot or line bonding is performed with a general adhesive, the bonding cannot be performed well. That is, the adhesive strength of some kinds of adhesives is weak and delamination of the glue occurs, or peeling occurs from one of the surfaces and immediately separates into pieces. In addition, some adhesives have a too strong adhesive force, and when they are separated, one of the paper surfaces is partially destroyed and transferred to the other surface. If this paper surface destruction is on the optical reading paper, fluffing will occur around the destruction and the paper passing to the reading device will be hindered. Further, when this destruction occurs on the pressure-sensitive recording sheet, the destroyed portion is transferred to the optical reading sheet, which also causes a trouble in passing the sheet to the reading device.
この様な問題を解決するために、本願出願人は先に接着

用帳票の出願をしている（実公昭63−5905）。In order to solve such a problem, the applicant of the present application has previously applied for a pressure-sensitive recording form characterized by spot-bonding or line-bonding with a polyisobutylene-based aqueous emulsion type adhesive as an adhesive.

れている。However, in the case of this device, since the effect of the adhesive depends only on the adhesive force of the adhesive, depending on the quality of the optical reading paper, the adhesive may be glued to the optical reading paper when the set is separated. It has been confirmed that the residual occurs, and further, this phenomenon is particularly remarkable in the case where the pressure sensitive recording sheet is pasted to a portion coated with a color-development inhibitor (desensitizer).

とを目的とするものである。The present invention is written in a state of being spot-bonded or line-bonded,
The sheets do not separate apart until each is used for paperwork, and when they separate, the adhesive may transfer to the pressure sensitive recording sheet and remain on the optical reading paper. An object of the present invention is to provide a form that can be separated on this paper surface without causing picking, and can also be separated on the surface of the pressure-sensitive recording sheet on which the color-forming inhibitor ink is present.

果を得ることができない。The reason why the natural rubber latex is used as the adhesive in the constitution of the present application is that the natural rubber adhesive is hydrophilic when used in combination with the other substances (a, b and c) described above. It has the property of exerting a strong binding force with the surface of the receptive developer layer. Therefore, when the paper quality (stiffness, surface smoothness, etc.) of one of the optical reading papers that are set and joined changes, When a coating layer of microcapsules containing oil droplets is provided on the optical reading paper, or a pressure-sensitive recording sheet to be set and bonded with these is coated with a color-development inhibitor (desensitizer). This is because even when glued to a sheet, it has a characteristic of exhibiting firm adhesiveness unless the paper sheet in the set state is artificially separated. However, other adhesives have a poor binding force to the surface of the electron-accepting developer layer, which is hydrophilic, in comparison with natural rubber latex, and cannot obtain an adhesive effect like natural rubber latex.

糊の凝集力が低い場合には、分離の際に糊の層間剥離が

問題がある。Next, the reason why the acrylic ester resin is used in combination is to further improve the cohesive force of the natural rubber latex.
That is, when separating the pasted paper sheet set, all of the paste can be transferred neatly to the strongly adhered side without causing delamination of the paste. Incidentally, when the cohesive force of the adhesive is low, there is a problem that the adhesive is delaminated during separation and adhesive residue is generated on both sheets.

インタール等が好適である。The reason why the tackifier is used in combination is to improve the tackiness of the adhesive (the tackiness is poor only with natural rubber latex). Incidentally, as the tackifier, alkylphenol formaldehyde resin and its rosin modified product, alkylphenol-acetylene resin, coumarone-indene resin, xylene-formaldehyde resin, polybutene, hydrogenated rosin and its processed products, pine tar, etc. are suitable.

ス、その他合成ワックス類等が挙げられる。The reason for using the wax emulsion together is to control the adhesive strength of the entire adhesive. That is, when the optical reading paper and the pressure-sensitive recording sheet are spot-bonded or line-bonded via an adhesive, the size of the bonding area (the bonding area may be changed depending on the application, for example, the bonding area is large In some cases, it may be necessary to weaken the adhesive force, while in other cases, if the adhesive area is small, it may be necessary to increase the adhesive force) to control the destruction of the paper surface by changing the adhesive strength. It is a thing. Examples of the wax constituting the wax emulsion used in the present invention include animal waxes such as beeswax and seraca wax, vegetable waxes such as carnauba wax, paraffin wax,
Examples include petroleum waxes such as microcrystalline wax, polyethylene wax, and other synthetic waxes.

る。In order to achieve the above purpose, the mixing ratio of these compositions is (a) ... 40-92.5 parts by weight (b) ... 2.5-40 parts by weight (c) ... 2.5-30 parts by weight. (D) The content is appropriately adjusted within the range of 2.5 to 50 parts by weight so as to obtain the desired effect. Incidentally, if the amount of (a) is less than 40 parts by weight, the property of the adhesive as an elastic body is impaired, and the form easily separates and becomes separated before being used for paperwork. On the other hand, 9
If it is more than 2.5 parts by weight, the adhesive strength will be too strong and the paper surface will be destroyed when separating the form. When the amount of (b) is less than 2.5 parts by weight, the cohesive force of the adhesive is weakened and the adhesive layer is liable to cause interlayer breakage when the form is separated. On the other hand, when the amount is 40 parts by weight or more, the adhesive strength of the adhesive becomes too strong and the paper surface is destroyed when the form is separated. If the amount of (c) is less than 2.5 parts by weight, the adhesive strength of the adhesive becomes weak, and the adhesive strength becomes extremely weak at the portion where the desensitizer is applied to the pressure-sensitive recording sheet.
When separating the form, the glue will be transferred to the back surface of the optical reading paper. On the other hand, when the amount is 30 parts by weight or more, the adhesive strength becomes too strong and the paper surface is destroyed when the form is separated. (D)
If the amount is less than 2.5 parts by weight, the adhesive strength of the adhesive becomes too strong and the paper surface is destroyed when the form is separated. On the other hand, when the amount is 50 parts by weight or more, the adhesive strength becomes weak, and the forms are likely to be separated before being used for paperwork, and to be separated.

る。That is, when the paper quality (for example, stiffness or smoothness) of the optical reading paper is changed, when a microcapsule coating layer is provided on the back surface of the optical reading paper, or when a desensitizer is applied to the pressure-sensitive recording sheet. In this case, when the set is separated, the adhesive does not remain on the optical reading sheet at all, and the adhesive is prepared so that it can be always transferred to the pressure-sensitive recording sheet. . Therefore, for example, when a coating layer of microcapsules is provided on the optical reading paper, the adhesive force between the optical reading paper and the adhesive becomes weak due to the coating layer. As an adhesive composition for adhering such an optical reading paper and a pressure-sensitive recording sheet, the ratio of natural rubber latex is increased and the ratio of wax emulsion is decreased. Further, when the pressure-sensitive recording sheet is coated with a desensitizer, the desensitizer layer becomes a cause of impairing the binding force between the adhesive and the pressure-sensitive recording sheet. The adhesive composition for adhering such a pressure-sensitive recording sheet and an optical reading paper is adjusted so as to obtain a desired effect by increasing the ratio of the tackifier.
