Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and has a structure in which a support sheet is provided with a printing layer coated on at least one side of a printer sheet. And a binder resin selected from the group consisting of polyester resin, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer resin, acrylic resin, and styrene resin. A sheet comprising a filler is wound into a roll, and when the rolled sheet is fed out and cut into sheets, the sheet is prevented from being curled.

That is, the inventor of the present invention has conducted intensive studies in order to solve the above-mentioned problems. As a result of using the foamed polyester film for the support of the sheet, the curl can be obtained even in a roll form. The inventor of the present invention found that a sheet without curling and strong water resistance could be obtained even if the sheet was cut off from the roll state without being rolled.

Hereinafter, the present invention will be described in detail. As the support, if a commercially available foamed polyester film having a specific gravity in the range of 0.7 to 1.2 is used, the curl when the roll is cut off into a single sheet from the roll shape due to its original excellent recovery force. Can be prevented.

As a printing layer provided on at least one surface of the support, if the printer is a wire dot ink ribbon recording system or a thermal transfer recording system, necessary items such as meter reading paper must be printed before printing. Therefore, it must have various printing aptitudes such as offset, gravure, screen, letterpress, etc. In addition, it must have high affinity with the wax of the ink sheet, or high ink absorption and setability of the ink ribbon. It becomes necessary characteristic.

As a binder resin for forming a print layer satisfying the above characteristics, polyester resin, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer resin, acrylic resin, styrene resin and the like are suitable. ing.

The filler is preferably an inorganic filler such as silica, calcium carbonate, magnesium carbonate, diatomaceous earth, talc and clay, and an organic filler such as styrene beads and polymethyl methacrylate beads.

Further, a surfactant such as a wetting agent, a sizing agent, an antifoaming agent or a plasticizer may be added to the combination of the binder resin and the filler for the purpose of surface modification. Alternatively, an antistatic agent may be added or applied.

Next, as a means for forming the sheet, a composition prepared by mixing the above-mentioned binder resin, filler, additives and the like at a specific ratio is used as a coating solution, and a known means such as a roll coater, a wire bar coater, a gravure coater is used. When the composition is coated on a support with a knife coater, a comber coater or the like so that the dry thickness is 2 to 15 μm, preferably 5 to 10 μm, and dried, the intended sheet of the present invention can be obtained.

When the printer is of a thermosensitive coloring type, a printing layer containing a thermosensitive coloring agent may be provided on the support according to the forming means.
