실험 절차
Using a method similar to that described in Example 1(a), 7.6 parts of 2-amino-3-cyano-5-formylthiophene were reacted with 9.7 parts of N-cyanoethyl-N-ethyl-m-toluidine to give 13 parts of the dye of the formula ##STR19## 3.8 parts of ethyl cyanoacetate, 1.5 parts of glacial acetic acid and 1.5 parts of piperidine were added to 6.0 parts of this dye in 45 parts by volume of dioxane, and the mixture was stirred for 16 hours at room temperature. Thereafter, the dye was precipitated by adding 50 parts of water and 50 parts of ice, the mixture was stirred for 1 hour and the product was filtered off under suction, washed neutral with water and dried to give 7 parts of the dye of the formula ##STR20## which dyes polyesters in fast dark blue hues.
