<p>Reactive azo dye (I) and its water-soluble salts are new: It is prepd. e.g. by reacting cyanuric chloride with the appropriate prim. amino azo dye. Dye is useful for greenish-yellow dyeing or printing of natural and regenerated cellulose or their mixts. with other fibres. (I) has excellent fastness to light, washing at 60-95 degrees C, Cl2-contg. baths, perspiration and acid or alkaline treatments, and has little tendency to interfere with reactive phthalocyanines when used with them to produce green dyeings.</p> |
