Zusammenfassung:	A novel process for the preparation of slates of a sandwich arrangement is provided, which comprises coating a polyurethane prepolymer compound solution formed by incorporating a water-conductive agent such as powders of asbestos and hydrophilic fiber powder into a polyurethane prepolymer having terminal isocyanate groups, on an unhardened raw slate containing water, piling another raw slate on the coated layer, and then effecting the foaming and hardening of the polyurethane prepolymer.
