Abstract
Abstract Iminoisoindolinone pigments of the formula WHEREIN X represents halogen atoms, Y represents a halogen atom, an alkoxy, cycloalkoxy, aralkoxy, aryloxy, alkylthio or arylthio group, R represents an aromatic radical containing a cyclic bound -CONH group, and Q represents an O-atom or the group =N-R and are useful for coloring plastics and lacquers in yellow shades having excellent fastness properties.
