Description

[0001]
[Industrial application fields]
The present invention relates to an overlapped binding sheet in which a plurality of sheets are overlapped or a part of an overlapped sheet formed by folding one sheet is detachably bonded, and a method for producing the same.
[0002]
[Prior art]
Conventional binding methods for the overlapped binding sheet include a case of binding linearly along one edge of the overlapped sheet (hereinafter referred to as line binding) and a case of binding in an annular shape along the periphery of the overlapped sheet ( Hereinafter, bag binding is generally performed. Then, in the case of line binding, the adhesive is applied in a linear form to be bonded, or is bound by paper staples (so-called paper binding), and in the case of bag binding, the adhesive is applied in a predetermined pattern and bonded. It is common to do.
[0003]
[Problems to be solved by the invention]
For this reason, conventionally, in the case of line binding, there is an inconvenience that when the overlapped binding sheets are stacked and stored, the thickness on one edge side corresponding to the adhesive application portion increases and an inclination occurs. On the other hand, in the case of bag binding, the application pattern of the adhesive is fixed, and there is an inconvenience that it is difficult to apply in an arbitrary pattern. Furthermore, it is necessary to provide a cutting perforation for separation in either case of line binding or bag binding. There is an inconvenience that it occurs and interferes with printing. An object of the present invention is to provide an overlapped binding sheet that eliminates such inconveniences.
[0004]
[Means for Solving the Problems]
In order to achieve this object, the overlapped binding sheet of the present invention is a pressure-sensitive adhesive layer that can be peeled after overlapping a plurality of sheets or folding a single sheet and adhering to one or both sides of the overlapping surface. Are laminated so that they can be peeled off at the print-corresponding portion of the pressure-sensitive adhesive layer by the printing pressure at the time of printing.
[0005]
Alternatively, the overlapped binding sheet may be configured by interposing a copying structure on a desired overlapping surface of the overlapping sheet so as to correspond to a part of the pressure-sensitive adhesive layer.
[0006]
The overlap-stitched sheet of the present invention is obtained by overlapping a plurality of sheets provided with a pressure-sensitive adhesive layer that can be peeled off after being bonded to at least one overlapping surface of the sheets, or by folding one sheet. None, the overlay sheet can be created by being peeled from the print-corresponding portion of the pressure-sensitive adhesive layer by the printing pressure applied from the exposed surface side of the overlay sheet. .
[0007]
The pressure-sensitive adhesive layer described above is composed of 100 parts by weight of a non-peelable pressure-sensitive adhesive base, and a fine particulate filler 20 to 130 exhibiting no affinity for the non-peelable pressure-sensitive adhesive base. It is good to form with the pressure sensitive adhesive composition formed by mix | blending a weight part. The non-peelable pressure-sensitive adhesive base can be arbitrarily selected from those conventionally used such as natural rubber and synthetic rubber, and in particular, natural rubber can be used with styrene and methacrylic acid. Natural rubber latex obtained by graft copolymerization of methyl is preferable in terms of blocking resistance, heat resistance, abrasion resistance, and the like.
[0008]
On the other hand, as the particulate filler, for example, zinc oxide, titanium oxide, calcium carbonate, kaolin, activated clay, spherical alumina, wheat starch, silica, glass powder, shirasu balloon and the like are used. These materials may be used alone (especially suitable for silica), or two or more of them may be combined. Further, when two or more kinds having different particle diameters are used in combination, the surface of the pressure-sensitive adhesive layer can be easily formed in a concavo-convex shape, which is advantageous in improving the peeling performance. When silica is added, the adhesive coating film can be strengthened, and due to its porosity, the adhesive easily adheres to the surface, and thus there is an advantage that the adhesive force and peel force can be easily adjusted. The fine particle filler preferably has an average particle size in the range of 5 to 30 μm, preferably 7 to 20 μm.
[0009]
In addition, when providing the above-mentioned pressure-sensitive adhesive layer only on one side of an overlapping surface, an adhesive force adjustment layer can also be provided in the surface which contacts this. The adhesion adjusting layer is preferably formed of a composition comprising 50 to 95 dry parts by weight of fine silica powder and 5 to 50 parts by weight of binder, but 50 to 95 parts by weight of solid silica finely dispersed in water. It is more preferable that the composition comprising 5 to 50 parts by weight of the binder is coated and formed with a coating weight of less than 3.0 g / m ² .
[0010]
[Action]
By providing a pressure-sensitive adhesive layer that can be peeled off after bonding on one or both sides of the overlapping surface, the print-corresponding portion of the pressure-sensitive adhesive layer is bonded to form an overlapped binding sheet by the printing pressure during printing. In addition, if the overlapping surface is separated after bonding, the pressure-sensitive adhesive layer can be peeled off, so that it can be easily peeled without damaging the bonded portion.
