BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure sensitive recording sheet integrated with a recording sheet, which has non-exposure of recording, copyability, water resistance, chemical resistance, oil resistance, scratch resistance and dust generation. As the recording sheet of a type having an inhibitory property, a record, a label,
It is a pressure-sensitive recording sheet integrated with a reserve sheet that can be used for applications such as slips, correspondence, entertainment items, and recording sheets for clean rooms.

2. Description of the Related Art The pressure-sensitive recording layer used in the present invention is a self-coloring type pressure-sensitive recording, which is developed from so-called carbonless copying paper. It is also called a hand paper. Its composition is a process of applying a coating of microcapsules containing a colorless dye (hereinafter referred to as a color-forming agent) on a support, and further, on the application, electron acceptance of acidic clay, phenolic resin, organic acidic substances, etc. A method of manufacturing by a two-layer coating consisting of two steps including the step of applying a functional substance (hereinafter, referred to as a color developer) (including one in which the coating order is reversed), the above two components, or any of One of the components is microencapsulated, mixed evenly, and then coated by one layer to produce a coating (Japanese Patent Publication No.
No. 7-16096) is known. In such a self-coloring type pressure-sensitive recording sheet, since the color former and the developer are present in the vicinity, it is easy to obtain a printed image with high color density,
There is a problem that unintended and undesired color stains easily occur due to friction during manufacturing or handling. As described above, the self-coloring type pressure-sensitive recording sheet is destined to satisfy both practically required coloring performance and control of unnecessary coloring stains under the conditions under which it is used. Efforts are being made to satisfy both of the conflicting properties of colored stains.

Further, in the self-coloring type pressure-sensitive recording sheet, the pressure-sensitive recorded information is inevitably exposed to the public, and when it is desired to hide the information content,
I had to put it in a separate bag.

Up to now, for example, a method of providing a laminate layer by a vacuum adhesion method (Japanese Patent Publication No. Sho 49-10857) or a plastic layer by a melt lamination method on the recording layer of a self-coloring type pressure-sensitive recording sheet. Methods (Japanese Utility Model Publication No. 52-149709), a method of providing a peeling layer on these protective layers, a method of applying a soluble polymer solution on a self-coloring type recording layer, and a method of forming a coating by drying. Are known. However, in these methods, the microcapsules are destroyed to cause remarkable color fog, or the microcapsules are covered with a resin, so that the original self-coloring type recording property is almost lost, and the color density and the color speed are decreased. Also, since these methods basically assume that the pressure-sensitive recording part is exposed,
The issue of record secrecy could not be resolved.

The present applicants have previously proposed the above problems by using a pressure-sensitive recording sheet having a structure in which a self-coloring type pressure-sensitive recording layer, a polyolefin resin laminate layer, an electron beam curable resin layer, and an opaque coating sheet are sequentially laminated. We applied for a pressure-sensitive recording sheet that solves the above problem and can conceal recorded information. In order to confirm the concealed pressure-sensitive recording portion, the content can be disclosed and confirmed by the user peeling off the portion of the opaque coating sheet from the polyolefin resin laminate layer. Further, the electron beam curable resin layer functions as a temporary adhesive layer until the opaque coating sheet is peeled off, and does not have re-adhesiveness after peeling off, and thus has excellent confidentiality. Further, when printing is performed on the surface of the opaque covering sheet, and when a record of the copy is required, a developer or its microcapsule is coated on one surface of the opaque covering sheet which is not in contact with the electron beam curable resin layer. However, similar to the general pressure-sensitive recording of copy slips, it is superposed on a pressure-sensitive recording paper coated with a separate color former or its microcapsules, and pressure-sensitive recording is performed. It was found that the color development of the can be made possible, and a preliminary record can be obtained. However, when printing is performed by an impact printer using an ink ribbon on the pressure-sensitive recording sheet laminated with a recording sheet coated with microcapsules, the recording density of the self-coloring type pressure-sensitive recording layer is insufficient. May be

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a pressure-sensitive recording sheet with a color developability enough to withstand use even when impact printing is performed through a recording sheet, and a color fog caused by friction. The present invention is to provide a pressure-sensitive recording sheet which has a high level of non-disclosure while satisfying the requirements of copyability, water resistance, chemical resistance, oil resistance, scratch resistance, dust generation suppression property, etc. .

It is also possible to mix and use an organic pigment, an inorganic pigment, and a colored dye / pigment in these electron beam curable resins.

The coating amount of the electron beam curable resin is not limited, but it is desired that the coating amount be thinner for the purpose of avoiding a decrease in pressure, and preferably ^{2 to} 40 g / m ² or less, more preferably. It is within the range of 3 to ²⁰ g / m ² or less. If it is less than this range, it is difficult to maintain good adhesion, and if it is more than this range, it works as a buffer material for pressure during pressure printing, and pressure-sensitive printing becomes unclear and color development is delayed.

The method of applying the electron beam curable resin of the present invention includes gravure roll and transfer roll coaters, bar coaters, roll coaters, air knife coaters, U comma coaters, AKKU coaters, smoothing coaters, microgravure coaters, air knives. Coater, reverse roll coater, 4 or 5

More preferably, an electron beam accelerator of 100 to 300 kV is used, and the absorbed dose in one pass is preferably 0.5 to 20 Mrad. If the accelerating voltage or the electron beam irradiation dose is lower than this range, the electron beam penetrating power is too low for sufficient curing, and if it is higher than this range, not only the energy efficiency deteriorates, but also the resin However, unfavorable effects on the quality such as the decomposition of additives and the deterioration of the strength of the base paper appear.

The electron beam accelerator may be, for example, an electro curtain system, a scanning type, a double scanning type or the like.

During electron beam irradiation, if the oxygen concentration is high, the curing of the electron beam curable resin is hindered.
Oxygen concentration is 600ppm or less, preferably 400p by performing replacement with an inert gas such as helium or carbon dioxide.
Irradiation is preferably performed in an atmosphere suppressed to pm or less.

By copying the opaque coating sheet, it is possible to make a copy without impairing the color development of the opaque coating sheet and the color development of the pressure-sensitive recording layer. It has the function of not being able to. By providing a pressure-sensitive recording layer on the surface of the recording sheet, it is possible to perform recording only by the impact of an impact printer without using an ink ribbon. Not only can pressure-sensitive recording be performed on the pressure-sensitive recording layer with good sensitivity, but also the recording system itself can be simplified.

[0036]

The present invention will be described in detail below with reference to examples, but the contents of the present invention are not limited to the examples.
All parts and% shown below are based on weight. Also,
Unless otherwise stated, the value indicating the coating amount is the coating amount after drying.

Preliminary Operation [Preparation of Pressure-Sensitive Recording Layer] Microcapsules containing a color-forming agent to be used for the pressure-sensitive recording sheet and the recording sheet were prepared as follows. First, 10 parts of crystal violet lactone was added to Hisol SAS N-296 (Nippon Petrochemical Co., Ltd.).
(Manufactured by Mfg. Co., Ltd.) and dissolved in 90 parts to obtain an internal phase oil. Melamine 10
And 25 parts of 37% formalin together with 100 parts of water at a pH of 8
The mixture was heated to obtain a melamine-formalin initial polycondensate. Then, the internal phase oil was emulsified into 150 parts of a 5% styrene / maleic anhydride copolymer aqueous solution, and the above melamine-formalin polycondensate was added to this emulsion to adjust the liquid temperature to 7
The mixture was kept at 0 ° C. for 2 hours to obtain a microcapsule dispersion liquid containing a color former having a melamine-formalin resin film. The average particle size of the obtained microcapsules was about 6 μm.

The coating liquid for the pressure-sensitive recording layer was prepared by the following formulation. The unit is dry parts by weight. Microcapsules containing color former 110 parts Developer (PR26298 manufactured by Sumitomo Durez Co., Ltd.) 60 parts Starch particles 280 parts Kaolin clay 70 parts Oxidized starch 100 parts

The pressure-sensitive recording sheet was prepared as follows. That is, a pressure-sensitive recording layer having the above composition was coated on a woodfree paper having a basis weight of 100 g / m ^{2 so} that the coating amount was 8 g / m ² , to obtain a pressure-sensitive recording sheet. Next, a polypropylene (density: 0.90) was formed on the recording surface of the pressure-sensitive recording sheet using a melt extrusion die as a polyolefin resin laminate layer.
0 g / cc) was laminated to a thickness of 20 μm.
In addition, a bifunctional acrylate as an electron beam curable resin (Aronix M-803 manufactured by Toagosei Kagaku Kogyo Co., Ltd.)
0: Aronix M-210 8: 2 mixture) 20
It is coated with an offset gravure coater so that it becomes g / m ^2, and an opaque coating sheet (under the pressure-sensitive recording paper for slips,
Mitsubishi Paper Mills Co., Ltd., under Mitsubishi NCR Super, N60, basis weight 60 g / m ² , uncoated surface with ² g / m ² polyvinyl alcohol backcoat layer is used. It was superposed so that it was in contact with the radiation curable resin, and was introduced into an electron beam irradiation device (Electrocurtain, manufactured by Energy Science Co., Ltd.) that had been subjected to nitrogen substitution, and was cured by irradiation with an electron beam accelerating voltage of 200 kV and an absorbed dose of 2 Mrad. Then, a pressure-sensitive recording sheet was obtained.

The copy sheet is a commercially available paper for pressure-sensitive recording paper for slips (manufactured by Mitsubishi Paper Mills, Ltd., on Mitsubishi NCR Super,
A pressure-sensitive recording layer having the same composition as that used in the pressure-sensitive recording sheet was formed on the non-coated surface of the coloring agent microcapsules having N50 and a basis weight of 50 g / m ^{2 so} that the coating amount was 8 g / m ^2. It was applied by coating to.

Example 1 A pressure-sensitive recording sheet integrated with a desired pressure-sensitive recording sheet was prepared by superposing the opaque coated sheet surface of the pressure-sensitive recording sheet prepared in the preliminary operation and the back surface of the recording sheet (coloring agent capsule coated surface). Obtained.

Comparative Example 1 As a copy sheet, a commercially available pressure-sensitive recording paper for slips (manufactured by Mitsubishi Paper Mills Ltd., Mitsubishi NCR Super, N60,
A proof sheet-integrated pressure-sensitive recording sheet was produced in the same manner as in Example 1 except that the grammage of 60 g / m ² ) was used as it was, that is, the pressure-sensitive recording layer was not provided on the surface of the upper paper.

Test: In Example 1 and Comparative Example 1, the color density of the pressure-sensitive recording layer portion of the pressure-sensitive recording sheet was evaluated for the pressure-sensitive recording sheet integrated with the recording sheet. The color density of each pressure-sensitive recording sheet is printed by applying a constant weight to the pressure-sensitive recording sheet using an impact printer, then the pressure-sensitive recording sheet is removed by removing the color-retaining sheet. The color printed surface was exposed and the color density was measured with a Macbeth RD919 reflection densitometer. In Example 1, the ink ribbon was not required when recording on the surface of the copy sheet, so that the weight was directly applied. On the other hand, in Comparative Example 1, since an ink ribbon was required for recording on the copy sheet, a weight was applied via the ink ribbon.

Evaluation: The pressure-sensitive recording sheet integrated with the recording sheet obtained in Example 1 had good color density in the pressure-sensitive recording layer portion of the pressure-sensitive recording sheet, and was at a practical level. On the other hand, in the pressure-sensitive recording sheet integrated with the recording sheet obtained in Comparative Example 1, printing must be performed through the ink ribbon in order to leave a record on the surface of the recording sheet. It became difficult for pressure to be transmitted to the pressure-sensitive recording layer of the pressure recording sheet, and the color development was impaired. In any of the pressure-sensitive recording sheets integrated with a recording sheet, the contents of the pressure-sensitive recording, which are conventionally possessed, were not impaired with respect to the concealing property and the peeling property of the opaque coating sheet.

[0045]

By providing the pressure-sensitive recording layer on the recording surface of the recording sheet, it is possible to print directly on the recording sheet without using an ink ribbon, and the recording system itself can be simplified. Since there is little pressure loss on the pressure-sensitive recording layer of the pressure-sensitive recording sheet, high color density can be obtained. Furthermore, the gloss, scratch resistance and abrasion resistance of the printed surface are maintained as before.
Since the opaque cover sheet has the pressure-sensitive recorded information, it can be exposed to the outside and can be handled without being exposed, and by peeling the opaque cover sheet as necessary,
You can read pressure-sensitive information. As mentioned above,
The pressure-sensitive recording sheet integrated with a copy sheet of the present invention can be used in many applications such as continuous slips, pasting slips, labels, correspondences such as postcards, recordings, and dust-free recording papers, and has practical value. Is a big one.
