PURPOSE:To obtain a water-dispersible substrate having excellent printability, water-resistance and stiffness, exhibiting high water-dispersibility when thrown into water and useful, as a substrate such as a releasing paper of sanitary belt, etc., by forming a specific coating layer on at least one surface of a water- soluble paper or water-dispersible paper. CONSTITUTION:A coating layer of a water-soluble resin is formed by coating at least one surface of a water-soluble paper or water-dispersible paper with a coating liquid produced by adding a water-soluble resin and a hydrophilic powder to a mixture of water and a solvent. A coating liquid having high concentration and viscosity can be dried in a short time without causing the foaming trouble. |
