紙を提供することを課題とする。SUMMARY OF THE INVENTION Film-laminated paper, which is no longer needed, is not recycled as waste paper, and wastes resources only by incineration or disposal. When incinerated, the air polluted, and when discarded, the film did not decompose. In view of these points, the present invention makes it possible to easily disintegrate the laminated film and the adhesive for laminating, as well as the paper base material, when the film laminated paper becomes unnecessary, and to easily recycle it. It is an object to provide a film laminated paper.

印刷が施された紙であってもよい。In the present invention, in order to obtain a film laminated paper by applying a water-soluble acrylic synthetic resin under an alkali to a paper substrate, a film formed by using a water-soluble acrylic synthetic resin under an alkali as a film material is used. The film may be laminated on a paper substrate. At this time, an adhesive made of a water-soluble acrylic synthetic resin under an alkali is used as an adhesive between the film and the paper substrate. The paper base material to be laminated can be applied to base paper, coated paper or impregnated paper using water-soluble acrylic synthetic resin under alkali as described above. It may be paper that has been subjected to offset printing and can be further deinked.

(Available from BELLAND) was bonded to a water-soluble acrylic synthetic resin (available from BELLAND) as an adhesive under an alkali to obtain a film-laminated paper. On the other hand, a stretched polypropylene film (15 μ, Toray Industries, Inc., Trefan) was dry-laminated with an adhesive (BLS-PG16, manufactured by Toyo Morton Co., Ltd.) on the same base paper as in the example to obtain a film laminated paper. This is referred to as a film laminate paper of a comparative example.

かる。In view of the above test results, the film laminate paper of the comparative example has the same resistance to wet compressive friction as the film laminate paper of the present invention and the surface friction property of the comparative example. Although the film laminate paper is slightly inferior to the film laminate paper according to the present invention, in the disintegration test at the time of recycling as waste paper, the laminate film paper of the comparative example is completely disintegrated. It is difficult to say that it is recyclable because fine lumps remain, but the film laminated paper according to the present invention has completely disintegrated not only the laminated film but also the adhesive for lamination. It turns out that recycling as waste paper can be easily achieved.
