In order to obtain a foamed sheet having such a multi-layered structure, the foamed layer existing on the writing surface side contains 1 to 1 foamable fine particles containing a liquid as a core substance in a pulp slurry mainly composed of pulp fibers. 40% is added, and in addition to this, wet paper strength enhancer, dry paper strength enhancer, sizing agent, filler, pigment, etc. are added as needed to make this a papermaking raw material. First, the sheet is made into a sheet by a paper machine capable of forming a sheet, such as a cylinder paper machine. After that, the amount of the expandable fine particles to be blended with the two layers and the three layers is adjusted, or the sheets composed mainly of the pulp as described above, which do not contain at all, are sequentially laminated.
In this case, it is not always necessary to blend the foamed fine particles into the first layer, and in the present invention, when the density distribution in the sheet is observed, if the sheet density on the writing surface side is clearly low, the particles are uniformly distributed. It is possible to improve the folding and restoring property more effectively and economically than the foamed sheet, and preferably the sheet.
It is only necessary that 70% or more of the foamed fine particles of the entire sheet be present in the layer extending from the central plane to the writing plane in the thickness direction of the sheet. In addition, as the degree of tightness of the entire sheet including the foam layer,
It is preferable to be in the range of 0.1 to 0.5, and especially the tightness is 0.5.
Above, it is difficult to obtain the expected effect.

This foam layer has a void having a spherical independent cell structure inside,
When the ballot paper is folded in half with the writing surface facing inward, this void is temporarily compressed and half crushed. Therefore, at the same time as the stress applied to the ballot is released, the sheet tends to be returned to its original state by the compressive elastic force of the void. Here, when the sheet is folded in two, the most compressed portion is the inner surface when folding in two, that is, the writing surface side. In order to work, the foamable fine particles in the sheet are distributed more uniformly on the writing surface side of the base paper where compressive stress acts when folded in two, rather than being evenly distributed over the entire sheet, which is economical. It is more effective from the perspective of. As a result, the ballot paper of the present invention has improved folding and restoring properties more effectively and economically.

Next, a coating layer was provided on the writing surface of this foamed sheet. That is, 60 parts of light calcium carbonate and 40 parts of polyvinyl alcohol were mixed and adjusted so that the solid content concentration of the paint was 20%, then sufficiently stirred with a Cowles disperser to obtain the resulting paint. A ballot paper was prepared by coating the surface of the foamed sheet with 5 g / m 2 by the metalling bar method. Using the obtained paper, the folding restoration property and the writability were evaluated. However, when folding the paper, creases were made so as to be parallel to the flow direction of the pulp fibers. The results are shown in Tables 1 and 2. Evaluation method for folding and restoring property The above ballot paper is sampled in a size of 10 mm in width and 60 mm in length. The obtained sample was folded in two and sandwiched between stainless steel plates, and a load of 1 kg was applied from above for 60 seconds, and then the load was released and the opening angle of the sample was measured 60 seconds later. Writability evaluation method Characters were directly written on the ballot paper with a pencil of HB, and the ease of writing was judged by sensory evaluation. ○ indicates that there is no problem, △ indicates that the writing area is slightly dented and fibers are entangled, but there is no problem in writing ability, and × indicates that the writing area is completely depressed and it is very difficult to write.

EFFECT OF THE INVENTION In the ballot for election produced by the constitution and method described above, the compressive stress is generated when the paper is folded in two so that the writing surface is on the inside. It is a mixed foamed layer with low density, and it is more effective due to the elastic force of many closed cells inside it.
This is a ballot paper that can be economically improved in bendability and is easy to recycle and incinerate because it is mainly composed of pulp.
