PURPOSE:To obtain the title composition which can dye an article clear blue uniformly in good reproducibility and can give a dyed article excellent in practical fastness, by mixing a specified dioxazine dye with a copper phthalocyanine dye. CONSTITUTION:The title composition is obtained by mixing at least one dioxazine dye (A) of formula I (wherein Z is vinyl or beta-sulfatoethyl, R1 is H or a 1-4C alkyl, R2 is a 1-4C alkyl which may be substituted with an aryl which may be substituted with a sulfo, carboxyl, sulfato or phosphato group or an allyl which may be substituted with a sulfo or carboxyl group) with at least one copper phthalocyanine dye (B) of formula II (wherein CuPc is copper phthalocyanine, l and m are each 1-3, and l+m=3-4) at a weight ratio of 90-10:10-90, and optionally adding an anionic surfactant, a dust- preventing agent, an antiseptic, etc. to the mixture. This composition is useful for dyeing a fiber material containing carbonamide and/or OH groups.
