Perylene-3,4,9,10-tetracarboxylic acid monoanhydride monoimide and monoimidazolide compounds, processes for their preparation and their use

Abstract

Abstract Compounds of the formula ##STR1## wherein X denotes a chlorine or bromine atom, n denotes a number from zero to 4 and Y denotes an oxygen atom or a nitrogen atom, and A, if Y represents an oxygen atom, is the phenyl radical, which can be substituted by substituents from the group comprising halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, carbalkoxy with 1-4 carbon atoms in the alkyl radical, hydroxyl, carboxyl, CF 3 , nitro, phenoxy, phenoxy which is substituted by C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy and/or halogen, phenylamino, phenylamino which is substituted in the phenyl radical by C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy and/or halogen, phenylazo and phenylazo which is substituted by C 1 -C 4 -alkyl, C 1 -C 4 -akloxy and/or halogen, or is the pyridyl radical, which can be substituted by halogen and/or C 1 -C 4 -alkyl, or A, if Y represents a nitrogen atom, is the o-phenylene radical, which, together with Y and the other nitrogen atom, forms the benzimidazole ring, it being possible for the benzene nucleus of the benzimidazole ring to be substituted by substituents from the group comprising halogen, C 1 -C 4 -alkyl and C 1 -C 4 -alkoxy, processes for their preparation and their use as colorants or their use as intermediates for the preparation of colorants.
