Abstract

NEW MATERIAL:Azomethine compounds of formula I (wherein R1, R2 are H, halogen, lower alkyl, lower alkoxy except when both of R1 and R2 are H simultaneously).
USE: Pigments which develop clear red to yellow color and exhibit particularly high chroma. Other pigment performances such as weather resistance, solvent resistance, chemical resistance, coloring power, etc. of the above compounds are similar to or higher than those of commercially available red to yellow high-quality org. pigments. The compounds are useful as coloring matters for paints, lacquers, printing inks, etc.
PREPARATION: Two moles of 3-imino-4,5,6,7-tetrachloroisoindoline-1-one of formula II is reacted with one mole of a diisocyanate compd. of formula III in an inert solvent to obtain the desired compd.
