Abstract

Abstract Bis-isoindoline pigments of the formula ##STR1## wherein A represents a carbocyclic or heterocyclic aromatic radical, Q represents an oxygen atom or an imino group, E represents a cyano or acetyl group, a group of the formula --COOR, wherein R represents a C 1 -C 4 -alkyl group or a phenyl group which is unsubstituted or substituted in the o-, p- or m-position by halogen atoms, C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy groups, or represents a group of the formula --CONHR 1 , wherein R 1 represents a hydrogen atom, a C 1 -C 4 -alkyl group or a phenyl group which is unsubstituted or substituted in the o-, p- or m-position by halogen atoms or C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy groups, X represents a hydrogen atom, Y represents a chlorine or bromine atom, M and n are integers from 0 to 4, P is an integer from 0 to 1, while the sum of m+n+p must be 4, and Z if p is 1 and m is 3, represents a nitro or C 2 -C 5 -alkoxycarbonyl group and, if p is 1 and n is 3, represents a chlorine atom or a group of the formula RW--, wherein R has the above meaning and W represents an oxygen or sulphur atom are valuable pigments coloring plastics, lacquers and printing inks in yellow to red shades of excellent fastness properties.

Claim 1
Independent Claim 176 words
A bis-isoindoline pigment of the formula ##STR34## wherein E is cyano and A is ##STR35## or 1,5- or 2,6-naphthylene. where B is a direct bond, --O--, --S--, --C 1 -C 4 -alkylene, -C 1 -C 4 -alkylenedioxy, phenylenedioxy, sulfonyl or --NHCO--; and X 1 , X 2 , Y 1 and Y 2 are independently hydrogen, chloro, C 1 -C 4 alkyl or C 1 -C 4 alkoxy; Q is oxo or imino; X is hydrogen; Y is chloro or bromo; m and n are integers from 0-4; p is an integer from 0 to 1, with the proviso that the sum of m+n+p must be 4; and Z is nitro or C 2 -C 5 alkoxycarbonyl when p is 1 and m is 3; or is chloro or RW-- where W is --O-- or --S-- when p is 1, and n is 3, where R is C 1 -C 4 -alkyl, phenyl, or phenyl substituted in the o-, p- or m- position by halo, C 1 -C 4 -alkyl or C 1 -C 4 alkoxy.
Claim 2
Dependent Claim 176 words
A bis-isoindoline pigment of the formula ##STR34## wherein E is cyano and A is ##STR35## or 1,5- or 2,6-naphthylene. where B is a direct bond, --O--, --S--, --C 1 -C 4 -alkylene, -C 1 -C 4 -alkylenedioxy, phenylenedioxy, sulfonyl or --NHCO--; and X 1 , X 2 , Y 1 and Y 2 are independently hydrogen, chloro, C 1 -C 4 alkyl or C 1 -C 4 alkoxy; Q is oxo or imino; X is hydrogen; Y is chloro or bromo; m and n are integers from 0-4; p is an integer from 0 to 1, with the proviso that the sum of m+n+p must be 4; and Z is nitro or C 2 -C 5 alkoxycarbonyl when p is 1 and m is 3; or is chloro or RW-- where W is --O-- or --S-- when p is 1, and n is 3, where R is C 1 -C 4 -alkyl, phenyl, or phenyl substituted in the o-, p- or m- position by halo, C 1 -C 4 -alkyl or C 1 -C 4 alkoxy.
