Summary:PROBLEM TO BE SOLVED: To provide a new oxidation base for oxidatively dyeing keratin fibers exhibiting good stability against external factors. SOLUTION: This 3-aminopyrazolo[1,5-a]pyridine compound represented by formula (I') (R'1is H, a halogen atom, an alkyl, an alkylthio, an alkoxy, amino, an alkylamino, a heterocyclic group, or the like; R'2and R'3are each identically or differently H, a halogen atom, nitro, a heterocyclic group or the like). The oxidation base for oxidatively dyeing keratin fibers contains the compound. A new composition for oxidatively dyeing keratin fibers contains the compound. A dyeing method uses the composition.
