Abstract: Composition (A) comprises: in a medium, at least one oxidation base comprising aminopyrazolopyridine bases (I) and (II), and their addition salts, solvates and salts; and at least one coupler comprising 4-aminoindole derivatives (II), and their addition salts, solvates and solvates of their salts. Composition (A) comprises: in a medium, at least one oxidation base comprising aminopyrazolopyridine bases of formula (I) and (II), and their addition salts, solvates and salts; and at least one coupler comprising 4-aminoindole derivatives of formula (III), and their addition salts, solvates and solvates of their salts.
