Abstract

A method for producing a halogenated organic pigment comprising a halogenation step of halogenating an organic pigment with a halogenating agent, wherein the halogenating agent comprises one or more N-haloimide compounds selected from the group consisting of trichloroisocyanuric acid, a metal salt of dichloroisocyanuric acid, tribromoisocyanuric acid, and a metal salt of dibromoisocyanuric acid. According to the present invention, a method for producing a halogenated organic pigment which does not use high toxic raw materials, does not generate a large amount of unfavorable by-products such as hydrogen halide gas and succinimide, and is excellent in terms of safety and productivity can be provided.
