    • A process for preparing a colorant of the formula which comprises preparing a first reaction mixture by admixing leucoquinizarin and, optionally, quinizarin, an aminobenzene substituted with an alcohol group of the formula —R1—OH, boric acid, and an optional solvent, and heating the first reaction mixture to prepare an alcohol-substituted colorant of the formula followed by converting the colorant thus prepared to either an ester-substituted colorant by reaction with an esterification compound which is either an anhydride of the formula or an acid of the formula R2COOH in the presence of an optional esterification catalyst, or a urethane-substituted colorant by reaction with an isocyanate compound of the formula R4—N═C═C═O, and brominating the colorant thus prepared, wherein either conversion to ester or urethane can be performed before bromination or bromination can be performed before conversion to ester or urethane.
    • 一种制备下式的着色剂的方法,其包括通过将无色茜素和任选的茜素,由式-R1-OH的醇基,硼酸和任选的溶剂取代的氨基苯混合制备第一反应混合物,并加热 第一反应混合物以制备下式的醇取代的着色剂,然后通过与下式的酸酐或式R 2 COOH的酸的酯化化合物反应将所制备的着色剂转化为酯取代的着色剂 通过与下式的异氰酸酯化合物反应,任选的酯化催化剂或氨基甲酸酯取代的着色剂的存在:“在线公式”=“铅”→R4-NCCO, ?在线公式描述=“在线公式”end =“tail”?>溴化如此制备的着色剂,其中转化为酯或氨基甲酸酯可以在溴化或溴化之前进行 可以在转化成酯或氨基甲酸酯之前进行。
