Abstract
962,261. Substituted chloropyridazines. CIBA Ltd. May 18, 1961 [May 23, 1960; April 13, 1961], No. 18192/61. Heading C2C. [Also in Division C4] Coupling components for use in the production of azo dyes (see Division C4) are obtained by reacting 3:4:5:6-tetrachloropyridazine with 2:4- diaminobenzene-1-sulphonic acid or with 2- amino-5-hydroxy-naphthalene-7-sulphonic acid.
