Abstract
A polyurethane resin composition comprising (A) a polycarbonate base polyurethane resin, (B) a P and N-containing non-halogen flame retardant, (C) a polyhydric alcohol, and (D) a silicone containing at least two reactive functional groups in the molecule obviates the problems of safety, environment and price and has sufficient flame retardance and improved mechanical properties such as tensile strength and elongation.
