Abstract: Isoindoline pigments of formula (I) are claimed, where R and R are each CN; Q is -CO-NR R or -CO-NR R ; or R +R = R ; Q is a (non)satd. (non)aromatic 5-7-membered heterocyclic ring system, opt. modified by condensn. or bridging to other heterocyclic or isocyclic ring systems, in which the hetero-atoms are N, O and/or S; R and R are each H or 1-4C alkyl; R is Q, opt. mono- to penta-substd. by 1-4C alkyl, halogen, CF3, 1-4C alkoxy, carbo(m)ethoxy, carbonamido (opt. substd. by 1-4C alkyl or phenyl), NO2, 1-4C acylamino or OH; R is H, 1-4C alkyl, phenyl, 1-4C alkoxy, halogen or 1-4C acylamino; R is H, 1-4C alkyl, halogen, CF3, OMe, OEt or NO2; m = 1-4; n = 1-3; and R is H or 1-4C alkyl. (I) are prepd. by reacting (a) an isoindoline cpd. (II) of formula (A: X and Y are gps. X and Y capable of nucleophilic exchange in the 1- and 3-positions) with (b) a cpd. of formula R -CH2-R (III), giving a cpd. (IV) of formula (A: X is CR R ); and then (b) reacting (IV) with a quinoxalindione of formula (V), esp. a 6-aminoquinoxalindione. In (III), X is pref. imino, (hemi)acetal or ketal gp.; and Y is pref. an imino gp.. In (II), H atoms in the -CH2- gp. are CH-acids. Stage (a) is carried out at 30-60, pref. 45-55 degrees C and pH 5-9, pref. 6-8.5.

Abstract: Novel isoindoline pigments of formula (I) are claimed, as are also (i) prepn. of (I) by reacting an isoindoline of formula (II) having nucleophilically-exchangeable gps. X and Y in the 1- and 3-positions with a cpd. of formula (III) in which the H atoms of the -CH2- gp. are CH acids so as to give an intermediate of formula (IV) which is then reacted with a benzimidazolone of formula (V); and (ii) the use of (I) in pigmenting high mol. wt. organic materials. R = CN; R = (a) CN; (b) an (un)satd. (non)aromatic 5-7 membered N, O and/or S heterocyclic ring opt. modified by condensation or bridging to further heterocyclic or isocyclic ring systems; (c) -CONR R where R and R = H or 1-4C alkyl; or (d) -CONR R where R = unsubstd. or with at least 5 1-4C alkyl, halogen, CF3, 1-4C alkoxy, carbo(m)ethoxy or carbonamide- or with one 1-4C alkyl or phenyl gp.-substd. carbonamide, NO2, 1-4C alkylamino or OH-substd. (un)satd., (non)aromatic, iso- or hetero-cyclic (N, O and/or S) 5-7-membered ring opt. modified as per the ring of (b) above; or R and R together = ring as per (b) above opt. substd. as per (d) but excluding NO2; R = H, 1-4C alkyl, phenyl, 1-4C alkoxy, halogen or 1-4C acylamino; R = H, 1-4C alkyl, halogen, CF3, MeO, EtO or NO2; m = 1, 2, 3 or 4; n = 1, 2 or 3; and R = H or 1-4C alkyl.
