Abstract

PURPOSE: To prepare a novel organic material giving, when heated, a beautiful azomethine dye having excellent fastness to light and washing, and useful for the coloring of synthetic fiber, by the addition reaction of a specific isoindoline compound with an aromatic primary amine.
CONSTITUTION: The addition reaction of (a) a compound of formula I [A is (substituted) aromatic ring; R is H, alkyl, or aromatic group], pref. 3-imino-4,5,6, 7-tetrachloroisoindoline-1-one and (b) and aromatic primary amine (pref. a diamine such as m-phenylenediamine) in an organic solvent affords the objective compound of formula II or III. The pref. molar ratio of the component (a) to (b) is 2 to 1. The compound thus obtained releases ammonia by heating at 100W300°C, and forms an azomethine dye.
USE: Coloring of synthetic fibers and plastics such as polyester, polyamide, etc.
