Abstract: Disclosed are 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic acid dianhydrides (I) and perylene-3,4,9,10-tetracarboxylic acids (Ia) in which R represents optionally substituted aryloxy, arylthio, hetaryloxy or hetarylthio. Also disclosed are the production of these compounds and their use as pigments, laser dyes and precursors for the production of fluorescent dyes, polymer colorants, pigments and pigment additives, as well as 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic acid diimides (VI) as intermediate products for these compounds.

Abstract: Disclosed are 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic acid dianhydrides (I) and perylene-3,4,9,10-tetracarboxylic acids (Ia) in which the variables have the following meanings: L , L independently of one another represent 1,2 ethylene, 1,2-ethenylene and 1,2-ethinylene; R , R independently of one another represent hydrogen or optionally substituted C1-C30 alkyl. Also disclosed are the production of these compounds and their use as pigments, laser dyes and precursors for the production of fluorescent dyes, polymer colorants, pigments and pigment additives, and 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic acid diimides (VI) as intermediate products for these compounds.

Abstract: The invention relates to a method for producing aqueous polymer dispersions containing colorants by radical aqueous emulsion polymerisation of ethylenically unsaturated monomers in the presence of radical-forming initiators. At least a proportion of the monomers is used in the form of an oil-in-water emulsion E1 whose disperse phase contains at least one oil-soluble colorant. The inventive method is characterised in that the disperse phase of E1 is essentially made up of colorant-containing monomer droplets with a diameter

Abstract: The disclosure relates to a N,N'-dimethylperylene-3,4,9,10-tetracarboxylic acid diimide pigment suitable for water-based paints and obtainable by: coating the diimide suspended in an aqueous medium with a resin containing carboxyl groups in the presence of perylene-3,4-dicarboxylic acid-imide-9-sulphonic acid or its salts and of a C8-C18 alkyl- or alkenyl amine; isolating, drying and subsequently dry-crushing the coated diimide.

Abstract: The invention concerns a process for producing and purifying perylene-3,4-dicarboxylic acid imides by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: reaction is carried out in the presence of a tertiary nitrogen base compound as the solvent and a transition metal or transition metal salt as the catalyst. The invention further concerns the purification of perylene-3,4-dicarboxylic acid imides obtained by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: the raw products are first heated in N-methyl pyrrolidone, the N-methyl pyrrolidone adducts thus produced are treated with a base in the presence of an organic diluting agent, and the products subsequently isolated undergo further treatment if necessary with an aqueous acid. The invention also concerns novel perylene-3,4-dicarboxylic acid imides and the use thereof as fluorescence dyes, pigments or pigment additive precursors.
