Procedure

A mixture of 32.3 g (45 mmol) of N-(2,6-diisopropylphenyl)-1,6,9-tribromoperylene-3,4-dicarboximide (prepared in accordance with Example 1a of WO 96/22 332), 27.0 g (180 mmol) of p-tert-butylphenol, 16.6 g (120 mmol) of anhydrous, finely pulverized potassium carbonate and 1200 ml of N-methylpyrrolidone (NMP) was heated at 120° C. with stirring for 6 h. After cooling to room temperature, the reaction mixture was introduced with stirring into 4500 g of 6% strength by weight aqueous hydrochloric acid, the mixture was subsequently stirred for 2 h, and the precipitated solid was filtered off, washed to neutrality with water and dried under reduced pressure at 100° C. Filtration through a short silica gel column using methylene chloride as eluent, and removal of the solvent under reduced pressure, gave 38.9 g (93%) of the desired product in the form of reddish violet crystals having a softening point of 156° C.
