Beschreibung
Zusammenfassung:	The present invention is an aqueous polyurethane resin composition for a flame retardant coated material comprised of an aqueous dispersion of a polyurethane resin obtained by extending a chain of an urethane prepolymer in an aqueous dispersion. The aqueous dispersion of the urethane prepolymer is obtained by reacting (a) a polyisocyanate component with (b) a polyol component which contains a phosphorus-containing polyol compound represented by the following general formula (1) as an essential component then dispersed the obtained prepolymer in the water, wherein a unit corresponding to the compound represented by the said general formula (1) is contained so that the phosphorus content in the urethane resin solid is 0.3 to 5.0 mass percent; R1 in the formula (1) represents an alkylene group having 2 to 4 carbon atoms, and m and n represent a number from 1 to 10.
