Abstract

NEW MATERIAL:A phthalide derivative of formula I (X is Cl or Br; n is 3 or 4; m is 1 or 0; n+m is 4; R is 1,4-phenylene, 4,4'-biphenylene, 4,4'-stilbenylene, 1,4- naphthylene, pyrenylene, azo-bis-4-phenylene, etc.; when R is 1,4-phenylene or 4,4'- biphenylene, it may contain halogen, methyl or methoxy).
EXAMPLE: N-p-Phenylene-bis-tetrachloroiminophthalide.
USE: Colorant of an organic polymer such as polyolefin and polycarbonate.
PROCESS: The objective compound is prepared by reacting a phthalic anhydride derivative of formula II with an aromatic diamine derivative of formula III in a weak basic organic solvent, and treating the reaction product with a dehydrating agnet.
