加熱により熱分解して塩基性成分を放出するものを意味
する。熱現像感光材料では熱による現像を促進するため
に塩基を用いるのが望ましく、感光材料の安定性を高め
るには塩基をプレカーサーの形で用いることが必要であ
る。かかる塩基プレカーサーを実用に供するためには常
温での安定性と加熱時の迅速な分解性とを両立させる必
要がある。
従来知られている塩基プレカーサーとしては、例えば米

しかしながら、これtti基プレカーサーとして用いた
画像形成材料は本質的に重大な欠点を有している。すな
わち、常温保存時の高い安定性と現像処理の急激な分解
という前述の□必須条件を満たすことができずそのため
、高い画像濃度が得られないか、あるいは保存中に塩基
