  • Patent number: 11649380
    Abstract: A water-dispersible sheet is described that maintains water dispersibility while providing suppressed time degradation of the tacky adhesiveness of a tacky adhesive layer. The water-dispersible sheet has a paper substrate with a multilayer structure. One layer of the multilayer structure is an inner layer that is not in contact with the tacky adhesive layer. Another layer is a surface layer that is in contact with the tacky adhesive layer. The layers independently include mixed pulps of a wood pulp and a refined pulp with an ?-cellulose content of 88 % by weight or more. The weight ratio of the layers and the beating degree of the mixed pulps are set in the specific ranges.
