PROBLEM TO BE SOLVED: To provide a multilayered paper containing recycled pulp, which is hardly yellowed even when being exposed to light such as sunlight and ultraviolet rays, and is produced by recycling resources.SOLUTION: The multilayered paper containing recycled pulp contains 40 mass% or more of recycled pulp in the whole of a base paper. When a layer out of layers in the base paper, which is arranged one surface, is defined as a surface layer, a layer arranged at the other surface is defined as a back side layer and a layer arranged between the surface layer and the back side layer is defined as an intermediate layer, respectively, (1) the intermediate layer is formed by one or more layers; (2) a blending ratio of recycled pulp in the intermediate layer is 90 mass% or more; (3) a blending ratio of recycled pulp in at least one layer out of the surface layer and the back side layer, or in both layers is 20 mass% or less; and (4) a surface of at least either the surface layer or the back side layer is a coated surface coated with either an ultraviolet ray absorber or sodium hypophosphite, or coated with both of the ultraviolet ray absorber and sodium hypophosphite. |
