開昭５６−８４０２２号公報に記載されている。Conventionally, various proposals have been made regarding contact arm water sheets in which a water-absorbing agent is applied to a water-permeable sheet (for example, Japanese Patent Application Laid-open No. 55-21203, Japanese Patent Publication No. 57-16773, Japanese Patent Publication No. 57-1677).
No. 8-58124, etc.), and in particular, a contact dehydration sheet using a mixture of a polymeric water-absorbing agent and a hydrophilic paste as a dehydrating agent is described in Japanese Utility Model Application Publication No. 56-84022.

った。However, in the conventionally known catalytic dewatering sheet as described above, a mixture of a polymeric water absorbing agent and a generally high viscosity hydrophilic paste is used, so air bubbles are created in this mixture.
However, the dispersion of the polymeric water-absorbing agent in the resulting contact dehydration sheet is non-uniform and the quality of the product is degraded. In addition, the water-absorbing agent had to be applied to the extent that the glue lost its adhesive strength, which required a large amount of water-absorbing agent.Furthermore, the sheet was hard and did not have sufficient adhesion to the material to be dehydrated, necessitating improvement. .

It has been discovered that a soft contact dehydration sheet that is free of air bubbles and has good adhesion to the material to be dehydrated can be obtained by separately existing a polymeric water absorbing agent and a hydrophilic glue in the contact dehydration sheet. The invention has been completed.
