<P>PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin composition which provides a uniform film molded body free from swelling and foaming even when being molded at high temperature and to provide the film molded body manufactured by using the same. <P>SOLUTION: In the aqueous polyurethane resin composition including an aqueous polyurethane resin produced from a polyisocyanate and a polyhydroxy compound and a nonionic surfactant and having ≥50 wt.% resin solid concentration, the aqueous polyurethane resin satisfies the following conditions: (a) 50 wt.% or more of the polyisocyanate is diphenyl methane diisocyanate, (b) a hydrophilic group contained in the aqueous polyurethane resin is 0.03 to 0.30 mmol per 1 g of the resin solid. <P>COPYRIGHT: (C)2010,JPO&INPIT |
