Reaction Steps

To dioxane (100 ml), 1-amino-2-cyano-4-(4-hydroxyanilino)anthraquinone (3.55 g), 2,4-difluoro-6-(1-pyrrolidinyl)triazine (1.9 g), triethylamine (1.1 g) and anhydrous potassium carbonate (1.4 g) were added, and the mixture was heated at 80° C. for 1 hour to effect condensation. The reaction liquor was treated as in Example 6 to produce 4.9 g of an anthraquinone dye of the following formula in a yield of 94%. ##STR46## The dye had a λ max (acetone) of 630 nm.
