The present invention relates to a flame-retarding agent comprising a phosphoramidate compound represented by Formula (I):
wherein R 1 and R 2 are each independently C 1-3 alkyl, R 11 and R 12 are each independently C 1-3 alkylene, R 13 is C 1-6 alkylene, B 1 is hydrogen or C 1-6 alkyl, and A is hydrogen or an organic group represented by Formula (Ia):
wherein R 3 and R 4 are each independently C 1-3 alkyl, R 14 and R 15 are each independently C 1-3 alkylene, and B 2 is hydrogen or C 1-6 alkyl, wherein when B 1 is C 1-6 alkyl, and A is hydrogen, B 1 and R 13 -A, taken together with nitrogen to which they are attached, may form a non-aromatic nitrogen-containing heterocycle, and wherein when B 1 is C 1-6 alkyl, A is an organic group represented by Formula (Ia), and B 2 is C 1-6 alkyl, B 1 and B 2 , taken together with nitrogen to which they are attached and with R 13 , may form a non-aromatic nitrogen-containing heterocycle. |
