In JP 2001-515009, the ignition performance is improved by combining bitetrazole with specific metal particles.
しかし、 このように特定の金属粒子を利用する技術では、 金属粒子が粉塵爆発 を発生しやすく、 一部の金属 （例えばボロン） が高価であるので、 好ましくない。 特開 2002— 29879号公報では、 複数のビテトラゾール類の使用が必須 となっているため、 混練の手間が増え、 製造コストを押し上げる。 特開 2000 - 319085号公報では、 塩基性硝酸銅が必須成分となっているため、 燃焼温 度が低ぐ、 着火性が悪い。 特開 2004— 83304号公報では、 19孔以上の 数多くの貫通孔を有するワングレイン型のガス発生剤が開示されているが、 小さ な貫通孔を数多く有しているため、 製造しにくい。 However, such a technique using specific metal particles is not preferable because the metal particles are likely to generate a dust explosion and some metals (for example, boron) are expensive. In Japanese Patent Laid-Open No. 2002-29879, the use of a plurality of bitetrazoles is indispensable, which increases the kneading work and increases the manufacturing cost.

表 1から明らかなとおり、本発明のワンダレインのェンハンサ（実施例 1〜3 ) と、 公知の B/KN03 (比較例 1 ) との対比から、 高価な B/KN03と同じ着火効 果が得られ、 単位当たりの発熱量や燃焼速度も優れていることが確認された。
As is apparent from Table 1, the wanderlein enhancer of the present invention (Examples 1 to 3) and the known B / KN03 (Comparative Example 1) can be compared to obtain the same ignition effect as the expensive B / KN03. It was confirmed that the calorific value per unit and the burning rate were excellent.
