Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a postcard laminating binder for laminating a recording paper capable of ink jet recording and a postcard, and a postcard laminating method capable of efficiently laminating.

[0002]

2. Description of the Related Art A conventional technique relating to the present invention will be described assuming that the recording paper is an ink jet recording paper. The ink jet recording system records fine images and characters by flying small droplets of ink by various operating principles and attaching them to a recording sheet such as paper. It is easy to use, has great flexibility in recording patterns, and does not require development-fixing, and is rapidly spreading in various applications as a recording device for various figures including Chinese characters and color images. Further, it is possible to obtain an image formed by the multi-color ink jet system which is comparable to multi-color printing by the plate making system. In addition, in applications requiring a small number of copies, it is being widely applied to the full-color image recording field because it is inexpensive.

As recording sheets used in the ink jet recording system, efforts have been made in terms of apparatuses and ink compositions in order to use high-quality paper or coated paper used for ordinary printing and writing. However, with the improvement of the performance of ink jet recording apparatuses such as high-speed, high-definition and full-color apparatuses, and expansion of applications, more advanced characteristics are also required for recording sheets. That is,
As the recording sheet, the density of print dots is high, the color tone is bright and vivid, the ink does not flow out or bleed even when the print dots overlap, and the print dots spread laterally. Is not unnecessarily large and high image reproducibility such as smooth surroundings and no blurring is required.

On the other hand, as an application for an individual who has a small number of copies to be made, it is used for postcards and the like, and inkjet recording of destinations and communication texts on both sides can be mentioned. Furthermore, as one of the recent environmental measures, there is a demand for recording sheets capable of recording on the front and back sides, which requires less number of sheets to be used. However, when ink-jet recording is performed on a general postcard, particularly when high-definition images are ink-jet recorded, the undulation of the opposite surface caused by ink bleeding and the visibility of the recording on the opposite surface due to strike-through of the ink on the opposite surface The problem of deterioration will arise.

When a recording sheet which can be ink-jet recorded on both sides is used for a postcard, a normal postcard, a prepaid postcard with a lottery number (a postcard with a year-end gift, a postcard for hot summer with a lottery, "Kamomeru"), etc. can be used. It is a private postcard and has low utility value because it is not possible to use the opportunity for lottery, and it is necessary to paste stamps even though the fee is the same as a postcard, and a postal code frame, postcard or similar description etc. Need to be applied to the surface. Also,
The water resistance of the recording paper that has been surface-treated for inkjet recording may be inadequate, and the printed part (including the inkjet coded postal code entry frame, etc.) may bleed due to moisture when stamps are applied, and the stamps may accept ink. Peeling with layers,
There was a problem such as falling off.

Since the surface of a postcard has a certain degree of ink jet recording property, the problem of utilizing ink jet recording and postcard can be solved by integrating the ink jet recorded recording paper and the postcard with glue or adhesive. Glue on the back of the recording paper after
Alternatively, when an adhesive is applied and attached to a postcard, there is a problem that the ink jet recording is blurred due to the glue, the water content or the solvent contained in the adhesive.

If the ink jet recording paper and the postcard are pasted with glue or an adhesive and then printing is performed by ink jet recording, the air permeability may change due to the moisture or solvent in the glue or the adhesive. However, there was a problem in that the water overflowed and the dryness was poor. When ink-jet recording (particularly color ink-jet recording) is performed on the front and back of a postcard, it is the same as when ink-jet recording is performed on non-coated type paper. The undulation on the other side caused by ink seepage when recording on one side, the other side There is a possibility that the visibility of recording may be deteriorated due to the strike-through of ink on the ink.

In order to overcome such problems, the present inventors have at least one or more ink receiving layers on one side of a support, and the other side shows tackiness and adhesiveness under normal conditions. Patent application was filed for the invention of a heat-adhesive recording paper which has a heat-adhesive layer of any one of a delayed tack layer, a hot-melt adhesive layer and a heat-seal layer, which exhibits stickiness or adhesiveness when heated without heating. .

Further, when the present inventors try to stick a postcard using such a heat-adhesive recording paper,
Paying attention to the fact that there was only a time-consuming and time-consuming method of stacking sheets one by one and heating them with an iron. A method for heat-bonding in a (microwave oven) and a dedicated fixed binder were invented and applied for a patent. However, when the pasting by the electromagnetic wave heating device and the pasting by the dedicated binder invented so far, the work such as fixing the outer periphery of the laminate of the postcard and the recording paper is required. Furthermore, when heating and adhering a recording paper having a heat-adhesive layer or an inkjet recording recording paper using an electromagnetic wave heating device (microwave oven), there is a problem that steam and odor generated from these recording papers remain in the storage. there were. These vapors and odors have left a serious problem considering that the electromagnetic wave heating device is used for cooking at home.

[0010]

SUMMARY OF THE INVENTION Therefore, the problem to be solved by the present invention is to efficiently bond an adhesive sheet with a heat-adhesive recording paper by using an electromagnetic wave heating device. The purpose is to supply a fixing binder capable of stacking a postcard and a recording sheet and capable of bringing the postcard and the recording sheet into close contact with each other during electromagnetic wave heating. Further, in the electromagnetic wave heating step, a box-shaped fixing binder that does not leave vapor or odor generated from recording paper or postcards is supplied into the electromagnetic wave heating device.

The present invention will be described in detail below.

In the present invention, the convenience of postcards and the ease of use of recording paper used for ink jet recording,
Both good recording properties were made compatible by efficiently pasting recording paper onto a postcard. What is important here is that the recording paper is a heat-adhesive recording paper originally having a laminating function, and the image quality of the recording paper already recorded by the laminating process,
Alternatively, it means that it can be attached to the back surface of a postcard without impairing the recording property for recording.

In the present invention, it is easy if the heat-adhesive recording paper and the postcard are superposed and heated by using an electromagnetic wave heating device (for example, a household microwave oven cooker using a high frequency electromagnetic wave having a frequency of 1000 to 3000 MHz). It can be attached to. In the laminating process, since no solvent such as glue or adhesive is present in the laminating process, the recording property such as ink jet recording is not impaired, and the inside of the electromagnetic wave heating device is not contaminated. It can be a postcard.

However, in the process of heating and laminating with an electromagnetic wave heating device, it is necessary to press-bond the recording paper and the postcard during heating in order to improve the adhesion to the recording paper and the strong adhesion. There is. If the pressure bonding is incomplete, that portion swells with steam or expanded gas generated by heating, and not only the adhesion is not sufficient, but also a bubble appears after the finish and the finish is raised.

The postcard laminating binder of the present invention will be described with reference to the drawings. As shown in FIG. 1, the postcard laminating binder of the present invention has a bottom plate and a side plate for fixing the position of one set or a plurality of sets of a postcard and a heat-adhesive recording sheet (hereinafter referred to as a postcard laminate). You can Next, as shown in FIG. 2, by providing a pressing plate on the postcard laminate, it is possible to heat and bond the postcard and the recording paper without deviation during heating.
Further, as shown in FIG. 3, if a fixing device is provided so that the distance between the pressing plate and the bottom plate is constant, the pressing plate will not be lifted during heating, and a good pressure-bonded state can be maintained.

When the top plate is provided as shown in FIG. 4, the postcard laminate is surrounded by a box constituted by the top plate, the side plate and the bottom plate to form a box-shaped postcard bonding binder. By surrounding the postcard laminate with a box, efficient heating and heat retention can be achieved, and the bonding time can be shortened. In addition, the steam and odor generated during heating do not escape to the outside and the inside of the electromagnetic wave heating device is not polluted. As shown in FIG. 5, when the thickness of the postcard laminate cannot satisfy the distance between the bottom plate and the top plate, it is possible to perform pressure bonding using a pressing plate.
Although the pressing plate in FIG. 5 is arranged on the top plate side, it may be on the bottom plate side or between postcard laminates.
It is preferable that the top plate and the bottom plate are fixed by a fixing device so that the distance between them is constant, or the pressing plate may be fixed so that the distance between the top plate and the bottom plate is constant.

As shown in FIG. 6, it is possible to provide the holding plate with a spring function so as to cope with various postcard laminate thicknesses. Even if the postcard laminate has a large volume, the expansion and contraction of the spring will always allow the pressing plate to press the plate for efficient bonding. The pressing plate having such a spring function can be used alone,
As shown in FIG. 7, a pressing plate having a spring function may be arranged on the top plate or the bottom plate and used. The pressing plate having the function of the spring may be made of a synthetic resin that is bent to provide elasticity, or may be a bag-like or porous material that can be expanded by heating. Further, the top plate and the bottom plate may be formed separately, or may be integrally formed in a double-spread form so as to be bent at the center.

The postcard laminating binder of the present invention suppresses the thermal expansion of the side plate during electromagnetic wave heating, and does not let the heated postcard or odor components generated from the recording paper escape to the inside of the electromagnetic wave heating device. By providing an outer peripheral plate capable of covering the periphery, a double box-shaped postcard can be used as a binder for laminating. FIG. 8 shows an example thereof, but the handleability is improved by integrating the outer peripheral plate with the top plate.
Further, as shown in the cross-sectional view of FIG. 9, by providing a locking mechanism between the outer peripheral plate and the side plate, it is possible to fix the distance between the top plate and the bottom plate, and it is possible to uniformly press the postcard laminate. Become.

The heat-adhesive recording paper can be attached to a postcard before printing, or can be attached to a postcard after printing. In the postcard laminated recording paper, not only the postcard and the heat-adhesive recording paper are isometric,
For the purpose of neatly aligning the edges of postcards and for preventing the postcards and recording papers from adhering (blocking) to each other at the edges, the postcards and recording papers have a longitudinal dimension of 14 mm.
It may be cut to a size of 0 mm or more and a lateral dimension of 90 mm or more. If it is smaller than this size, it does not satisfy the standard for postcards, which is not preferable. For the purpose of obtaining such a size, and for the purpose of eliminating unnecessary adhesion on all sides (edges) of the postcard laminated recording paper, after the heat-adhesive recording paper and the postcard have been laminated, The entire circumference can be punched out to a predetermined size and punched postcard laminated recording paper can be obtained.

In the present invention, the non-metallic fixed binder for electromagnetic wave heating, which can fix the heat-adhesive recording paper and the postcard, is preferably a synthetic resin.
More preferably, at least a synthetic resin having a high softening point,
Alternatively, it is preferably made of a thermosetting resin.

In the present invention, the base paper preferably used as the support for the recording paper is composed mainly of wood pulp and pigment. As wood pulp, LBKP, NB
Chemical pulp such as KP, GP, PGW, RMP, TM
Mechanical pulp such as P, CTMP, CMP, CGP, DI
P, such as waste paper pulp, and the like, if necessary, conventionally known pigments and binders and sizing agents and fixing agents,
Various types of additives such as a yield improver, a cationizing agent, and a paper strength enhancer are mixed and used to produce a support by various devices such as a Fourdrinier paper machine, a cylinder paper machine and a twin wire paper machine. It is possible, and papermaking can be performed with acidity, neutrality, and alkalinity.
When an ink receiving layer is provided for inkjet recording or the like, the ink receiving layer may be provided on the base paper as it is, or the ink receiving layer may be provided after a size press such as starch or polyvinyl alcohol or an anchor coat layer is provided. It may be a multi-layered ink receiving layer.

Further, the base paper may be subjected to on-machine treatment with a calendering device comprising a metal roll and a synthetic resin roll. At that time, off-machine processing may be performed, and after processing, flatness may be controlled by further performing calendar processing using a machine calendar, a super calendar, or the like.

The coating liquid that constitutes the delayed tack layer, which is one of the heat-adhesive layers, is an acrylic resin, vinyl chloride resin, vinyl acetate resin, styrene / acrylic copolymer resin, styrene / butadiene copolymer resin, polystyrene. One or several crystalline (solid) plasticizers such as dicyclohexyl phthalate, diphenyl phthalate, N-cyclohexyl-p-toluenesulfonamide, o / p-toluenesulfonamide, etc. may be added to a dispersion liquid of resin, polyamide resin or the like. included.

The delayed tack layer obtained by applying this coating solution and drying it at a temperature below the melting point of the plasticizer is dry to the touch in a normal state, and can be passed through a general ink jet recording printer without any problem. Possible, but
Once heated above the melting point of the plasticizer, the delayed tack layer is plasticized and becomes tacky. Therefore, it can be bonded to high-quality paper, glass, metal, synthetic resin sheet, wood, etc. by light pressure, and the adhesiveness generated here remains even if the plasticizer is recrystallized. 3 to 6 in the delayed tack layer
It is possible to improve the paper passing property of the printer by containing 0% by weight of the pigment.

The resin constituting the hot melt layer, which is one of the heat-adhesive layers, is generally a thermoplastic material (100% solids) that melts in the temperature range of 60 to 180 ° C., and the polymer, resin and Wax is used. That is, alkyd (modified polyester), asphalt and coal tar bitumen, coumarone-indene resin, rosin and its derivatives, terpene resin, wax (mineral, plant and petroleum), ethylene / ethyl acrylate copolymer, ethylene / acetic acid. Vinyl copolymer, polyethylene, polyvinyl acetate and its copolymer, polycarbonate, polystyrene and its copolymer, polystyrene and its copolymer, polypropylene, polyvinyl ether, polyamide, polyester (thermoplastic), phenoxy resin (plasticizing ), Polyisoprene, polyurethane, thermoplastic elastomer (SBS, SIS,
Resins such as SEBS) are used.

The hot melt adhesive basically contains a resin having the following three functions. That is, a high molecular weight polymer that imparts viscosity to the melt and cohesiveness to the solid, tackiness,
Synthetic elastomers that increase elasticity and strength, synthetic resins or natural resins that impart viscosity and fluidity and promote wettability. It may also contain waxes which reduce the cost and lower the viscosity of the mixture and make it easier to apply.
The hot melt layer can be applied as a solvent solution or as an emulsion by coating and drying, or by hot melt extrusion. By containing up to 60% by weight of the pigment in the hot melt layer, it is possible to improve the paper passing property of the printer.

The heat-sealing coating material constituting the heat-sealing layer, which is one of the heat-adhesive layers, is "all about converting" (published by Processing Technology Research Group, 1993).
, Which is a so-called heat seal coating agent in a narrow sense as described in P351-), and is different from the solventless hot melt coating resin. For example, as its constituent resin, polyolefin resin, polyester,
It is used in the form of an organic solvent solution of ethylene / vinyl acetate copolymer resin, polyacrylate, vinyl chloride acetate, ethylene / acrylic acid copolymer resin, or an aqueous dispersion solution.

A coating liquid is prepared by using the resin, and coating is carried out.
The heat-sealing layer obtained by drying at a temperature higher than the minimum film-forming temperature is normally dry without stickiness even when touched with a finger, and can be passed through a general inkjet recording printer without problems. It is possible, but once heated above the melting point, the heat seal layer is plasticized and becomes sticky, and it is possible to bond to high quality paper, glass, metal, synthetic resin sheet, wood etc. with light pressure,
The adhesiveness generated here remains even after re-cooling. The heat seal layer can be applied as a solvent solution or as an emulsion and dried.

The delayed tack layer, hot melt layer and heat seal layer (hereinafter collectively referred to as adhesive layer) may further contain other additives such as a dispersant, a thickener, a fluidity improver, a defoaming agent, Foam suppressor, release agent, foaming agent, penetrant, coloring dye, coloring pigment, fluorescent whitening agent, ultraviolet absorber, antioxidant, antiseptic, antifungal agent, water resistance agent, wet paper strength enhancer,
A dry paper strengthening agent, an antistatic agent, an antiaging agent, and the like can also be appropriately added.

The coating amount of the adhesive layer varies depending on the adhesive method, but it is preferably in the range of 5 to 40 g / m ^{2 for} the purpose of ensuring good adhesiveness and ink jet recording property. When the coating amount of the adhesive layer is smaller than this range, the adhesion is insufficient and the bonding is weak. If it is larger than this range, it not only hinders the running of the paper but also causes a cost increase economically.

[0043]

When the postcard laminating binder of the present invention is used, for example, an adhesive type recording paper having an ink receiving layer can be easily and efficiently laminated with a postcard by an electromagnetic wave heating device. In such a laminating method, a solvent such as a glue or an adhesive or a solvent is not present in the laminating step, so that the ink jet recording property is not impaired. Furthermore, an adhesive type recording paper having an ink receiving layer on one surface of the support and having an adhesive layer on the other surface, which has printer paper-passing property and does not normally exhibit adhesiveness or adhesiveness,
Sometimes it is cut to a predetermined size, so it is easy to position the postcard on the adhesive surface, and it is possible to easily position it by aligning the edge surface, and it is stored as it is in the side plate of the postcard bonding binder. Then, by press-bonding with the pressing plate, it is possible to bond the postcard and the recording paper without misalignment. In particular, by using a box-shaped or double box-shaped postcard laminating binder, postcards can be laminated without letting steam and odors generated during heating of postcards and recording paper escape into the electromagnetic wave heating device (microwave oven). It is possible. Further, by using the binder for sticking postcards of the present invention, it is possible to create a unique and beautiful postcard by adhering it to the back of a postcard or a prepayment postcard with a lottery number.

Comparative Example 4 The recording paper A obtained in Preliminary operation 2 was made into a set by superimposing the heat-bonding surface of the recording paper and the back surface of the official postcard, and the entire surface of the postcard could be covered in a bundle of 20 sets. The front and back of the bundle were fixed with a binder of a size (ABS resin), placed in a household microwave oven (500w) and heated for 30 seconds to obtain a postcard laminated recording paper. Similarly, the recording sheets B and C were also laminated.

The bonding of the adhesive type supports and recording sheets of Examples and Comparative Examples was tested by the following method. The results are shown in Table 1 below. In addition, the notation of the result is the adhesive type support A,
A / B / C in the order of the adhesive support B and the adhesive support C, or in the order of the recording paper A, the recording paper B, and the recording paper C.
Each test evaluation is represented in the form of.

<Test method> 1) Lamination stability All postcard laminating recording papers obtained in Examples and Comparative Examples were observed. In the case where the adhesive support and the heat-adhesive recording paper are bonded to each other on the entire surface of the recording paper, the adhesive support and the recording paper are bonded to the postcard. If some parts have wrinkles or floats, the score is -5 points for each sheet, and if there is no sticking, the score is -10 points for each sheet. Multiply by each number and the total is stable. It was sex.

2) Laminating operability In the processes of fixing the postcard, the adhesive type support and the recording paper in the Examples and Comparative Examples, the laminating operability was judged to be relatively excellent, good, average and acceptable. . Even if it is acceptable, the operability is extremely good as compared with the case where the postcard and the adhesive type support, and the recording papers are bonded one by one using a pressure sensitive adhesive as a medium.

3) Residual odor property In postcard laminating in Examples and Comparative Examples, when the odor generated when the heating adhesive is heated remains in the electromagnetic wave heating device, the odor property is inferior and the odor is slightly odorous. The degree of odor was similar to that of odor, the odor was good when almost no odor was felt, and the odor was excellent when no odor remained in the electromagnetic heating device.

[Table 1]

<Evaluation> As is clear from the examples, the use of the binder for postcard laminating of the present invention greatly simplifies the process of accommodating the adhesive type support or the heat-adhesive type recording paper and the postcards. Not only that, the stability of the adhesion is good when they are stuck together by using the electromagnetic wave heating device, and the odor of the adhesive does not remain in the electromagnetic wave heating device. It is possible to easily bond even recording paper which has been recorded by any method such as inkjet recording, printing, printing, sumi-e, sublimation type thermal transfer, impact printer, etc., without disturbing the recording. On the other hand, as is clear from the comparative example, laminating using an electromagnetic wave heating device is much more efficient and efficient than laminating one by one with an adhesive, but the sides of the postcard laminate are fixed. It takes a lot of time to fix it, or to fix it on its entire surface and its sides. Furthermore, since the edge surface is exposed in the method of the comparative example, when heated in the electromagnetic wave heating device, the heated adhesive component remains in the electromagnetic wave heating device as an odor, and the device may handle food. Is not preferable.
