EXAMPLE - N,N'-Bis-N-(2,6-diisopropylphenyl)-1,6,11,16-tetrakis(4-(1,1,3,3-tetramethylbutyl)phenoxy)-8,9:18,19-dinapthoquaterrylene-3,4:13,14-bis(dicarboximide) (0.70 g) in 2-methyl-2-butanol (200 ml) was heated at 55 degrees C. After 2 hours, potassium hydroxide (0.61 g) and potassium fluoride (0.63 g) were added and heated at about 100 degrees C and 16 hours. Further, 50 wt.% of acetic acid (100 ml) was dropped at 70 degrees C for 1 hour. The reaction product was precipitated with water, washed, filtered with hot water and dried in vacuum at 100 degrees C to obtain N,N'-bis-N-(2,6-diisopropylphenyl)-1,6,11,16-tetrakis(4-(1,1,3,3- tetramethylbutyl)phenoxy)-8,9:18,19-dinapthoquaterrylene-3,4:13,14-tetracarboxylic acidmonoimidemonoanhydride (0.25 g).
