Isoindoline pigments

Isoindoline pigments of the general formula I in which the variables are defined as follows: R1 is C1-C4-alkyl; R2 is hydrogen or C1-C4-alkyl, whose value expressing ease of dispersion in LDPE is 10 and which require a reduction ratio of 5 to obtain of standard depth of shade.
