Abstract
Official abstract text for this publication.
The present invention provides a sheet that has excellent lubricity and good touch feeling under wet conditions and suffers from little drop of the lubricity even if the sheet is used repeatedly. In the sheet of the present invention, a layer of modified polyalkylene oxide obtainable by reacting a polyalkylene oxide compound, a diol compound, and a diisocyanate compound together is directly formed on a surface of a substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a sheet comprising a substrate and a layer of modified polyalkylene oxide formed directly on a surface of the substrate, the method consisting of: forming a solution by dissolving a solid modified polyalkylene oxide in a solvent; applying the solution onto the surface of the substrate and drying the applied solution to form the layer of modified polyalkylene oxide; wherein the solvent is a mixed solvent of an organic solvent and water; wherein the organic solvent is an alcohol; wherein the organic solvent with water is a mixing ratio of 100 to 1100 parts by mass of the organic solvent per 100 parts by mass of water; wherein modified polyalkylene oxide is a reaction product of a polyalkylene oxide compound, a diol compound, and a diisocyanate compound; and wherein the substrate is at least one of the group consisting of resins and metals. 2. The method for producing a sheet according to claim 1 , wherein the amount of the solvent used in the solution is 150 to 2,500 parts by mass per 100 parts by mass of modified polyalkylene oxide. 3. The method for producing a sheet according to claim 1 , wherein the organic solvent is ethanol and/or isopropyl alcohol.
