Title:
METHOD FOR PRODUCING HALOGENATED ORGANIC PIGMENT, HALOGENATED ORGANIC PIGMENT PRODUCED BY SAID PRODUCTION METHOD, AND COLORED COMPOSITION CONTAINING SAID HALOGENATED ORGANIC PIGMENT
Document Type and Number:
WIPO Patent Application WO/2015/019659
Kind Code:
A1
Abstract:
A method for producing a halogenated organic pigment, which is characterized by comprising a halogenation step of halogenating an organic pigment with a halogenating agent, wherein the halogenating agent comprises at least one N-haloimide compound 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, it becomes possible to provide a method for producing a halogenated organic pigment with high safety and high productivity, in which the use of a highly toxic raw material is not required and undesirable by-products such as a hydrogen halide gas or succinic acid imide is not produced in a large quantity.
