Abstract
NEW MATERIAL:Diazaphenalene derivative of formula I [R1 is H, halogen, OH, lower alkyl, aryl, -NR7R8, -COOR7, -COR7R8 (R7,8 are H, lower alkyl, etc.),; R3,5,6 are H, halogen, -COOR7, etc,; R4 is H, halogen, cyano, -NR7R8, etc.; Y is group IV, etc.].
USE: Orange to reddish violet organic pigment.
PROCESS: A compound of formula II (R1' is H, halogen, -NR7R8, etc.; R2' is H, halogen, OH, lower alkyl, lower alkoxy, lower haloalkyl, etc.) is made to react with a carboxylic acid anhydirde of formula III (Z1 is group Y, etc.) or its reactive derivative
