See full text

A water-dispersible sheet is described having suppressed time degradation of the tacky adhesiveness of the tacky adhesive layer, while maintaining water dispersibility. The base paper of the water-dispersible sheet has a multilayer structure, including an inner layer which is not in contact with a tacky adhesive layer and a surface layer which is in contact with the tacky adhesive layer. The layers are independently mixtures of papermaking fibers and an alkalized fibrous carboxymethyl cellulose.
