SEMICARBAZIDE-METAL COMPLEXES AND GAS GENERATING AGENT FOR AIR BAGS

摘要

A gas generating agent for air bags which has desirable properties such as the ability to generate a significantly large amount of gas, a low combustion temperature, etc.; and semicarbazide-metal complexes usable as the base of the agent. The agent contains as the active ingredient at least one base selected among semicarbazide-metal complexes represented by the general formula: [M(X)1](NO3)m(OH)n wherein M represents Mg, Al, Ca, Mn, Cu, Zn, or Fe; X represents H2NNHCONH2; 1 is 2 or 3; m is an integer of 1 to 3; and n is an integer of 0 to 2, provided that (m+n) is equal to the ionic valance of the metal represented by M.
