PURPOSE:To provide the title colored, weakly acidic composition good in storage stability, containing hydrogen peroxide, a carboxylic acid-based polymer and pigment at a specified proportion. CONSTITUTION:The objective composition with a pH1.5-6, containing (A) 0.5-10wt.% of hydrogen peroxide, (B) 0.05-5wt.% of a carboxylic acid-based polymer including polyacrylic acid (salt) or poly-alpha-hydroxyacrylic acid (salt) pref. 1000-100000 in average molecular weight and/or maleic acid-based polymer 500-100000 in average molecular weight, and (C) 0.0001-1wt.% of a pref. phthalocyanine-based pigment. |
