Abstract

See full text

Provided is a polyurethane aqueous dispersion characterized in having practical utility in terms of processing suitability when a formed film is produced by salt coagulation method, and characterized in that a formed film obtained from the same has practical utility in terms of resistance against ethanol water. A polyurethane aqueous dispersion for a formed film, the formed film being obtained by using the polyurethane aqueous dispersion and a coagulant liquid in combination, is obtained by: neutralizing an isocyanate group-terminated prepolymer obtained by reaction of a polyisocyanate (A) composed of diphenylmethane diisocyanate and alicyclic diisocyanate, a random copolymer (B) of ethylene oxide and tetrahydrofuran, a polyol (C) having a number average molecular weight of 1000 to 5000, a polyhydric alcohol-based chain extender (D) having a number average molecular weight of 400 or less, and a diol compound (E) having a carboxyl group; and dispersing the obtained neutralized substance in water, and thereafter causing a chain extension reaction using an amine-based chain extender (F).
