Zusammenfassung:The present invention provides a method for producing a leathery sheet material excellent in hand characteristics and 5 abrasion-resistance, said method being excellent in productivity. The present invention provides a method for producing a leathery sheet material which comprises applying a heat-sensitive coagulable emulsion (A) to a fiber material substrate without a softening and water-repellent treatment and successively carrying out heat coagulation, wherein said heat-sensitive coagulable emulsion (A) contains, as essential components, a polyurethane resin (a), a softening repellent (b), a nonionic surfactant with a cloud point of 40 to 98°C (c) , and an inorganic salt (d) , and the weight ratio (b)/(a) is in a range of 0.005 to 0.2.
