Gas-generating agent composition

Abstract

There is provided a gas-generating agent composition having a very small pressure exponent and an extremely low pressure dependence of the burning rate. The gas-generating agent composition of the present invention contains a nitrogen-containing organic compound as a fuel and ammonium nitrate as an oxidizing agent, wherein the ratio of the nitrogen-containing organic compound to the ammonium nitrate (the former/the latter: weight ratio) is 35/65 or less. In the gas-generating agent composition, a copper compound may be further blended in a proportion of more than 0 part by weight and 30 parts by weight or less based on 100 parts by weight of the total amount of the nitrogen-containing organic compound and ammonium nitrate. The copper compound is preferably basic copper nitrate. Further, the nitrogen-containing organic compound is preferably a guanidine derivative, particularly preferably a guanidine nitrate.
