    Abstract: The invention relates to rylene dyes of the general formula (I), wherein the variables have the following meanings: R represents hydrogen; optionally substituted C1-C30 alkyl-C5-C8-cycloalkyl, aryl or hetaryl; R' represents optionally substituted C2-C30 alkyl or C5-C8 cycloalkyl, substituted methyl; and n is 0 or 1. The invention also relates to the preparation and use of said dyes for coloring highly molecular organic and inorganic materials and to 9-amino-perylene-3,4-dicarboxylic acid imides (Va) as their intermediate products.

    Abstract: Black perylene pigments (I) comprising fused-ring dipyridoperylenedione isomers and having a black number of at least 210 in an alkyd/melamine stoving lacquer are new. Black perylene pigments (I) comprising fused-ring dipyridoperylenedione isomers of formula (Ia) and/or (Ib) and having a black number of at least 210 in an alkyd/melamine stoving lacquer are new.
