• at least one styphnate selected from the group consisting of potassium-calcium styphnate, basic calcium styphnate and basic potassium-calcium styphnate;
• and
• one or more additives selected from:
• an oxidising agent selected from the group consisting of nitrates of the alkali or alkaline-earth metals or of ammonium, perchlorates of the alkali or alkaline-earth metals or of ammonium, peroxides of the alkaline-earth metals, of zinc and mixtures of these components;
• a reducing agent selected from the group consisting of aluminium, titanium, titanium hydride, boron, boron hydride, zirconium, zirconium hydride, silicon, graphite, active carbon, carbon black and mixtures of these components;
• a sensitizer selected from the group consisting of tetrazene, potassium dinitrobenzofuroxanate, diazodinitrophenol and mixtures of these components;
• a binder selected from the group consisting of adhesin, cellulose and derivatives thereof, polyvinylbutyrals, polynitropolyphenylene, polynitrophenyl ether, plexigum, polyvinyl acetate, copolymers and mixtures of these components;
• a high-energy additive selected from the group consisting of hexogene, octogene, nitropenta and nitrocellulose and mixtures of these components;
• and
