    Abstract: New perylene compounds based on perylene-3,4,9,10-tetracarboxylic monoanhydride monoimides substituted on one or both imide nitrogen atoms by alkylene- or arylenesulphonic groups, or on corresponding tetracarboxylic diimides or on a halogenated product thereof can be used not only as dispersing agents for pigments of the same class of compounds or other categories but also directly as pigments and fluorescent as well as polymer-soluble dyes.

    Abstract: PCT No. PCT/EP90/01311 Sec. 371 Date Mar. 6, 1992 Sec. 102(e) Date Mar. 6, 1992 PCT Filed Aug. 9, 1990 PCT Pub. No. WO91/02034 PCT Pub. Date Feb. 21, 1991.Pigment preparations consisting essentially of (a) at least one pigment based on perylene-3,4,9,10-tetracarboxylic dianhydride or on corresponding monoimides or diimides of tetracarboxylic acid monoanhydride, or a halogenation product thereof, (b) at least one pigment dispergent based on perylene-3,4,9,10-monoimide substituted on one or both imide nitrogen atoms by alkylene or arylene sulphonic or carboxylic acid groups or on corresponding diimides of tetracarboxylic acid monoanhydride, or a halogenation product thereof. The dispergents used appreciably enhance the key properties of perylene pigments, such as dispersibility, coloring power, stability to flocculation, transparency, rheological behavior and surface properties of the application medium. These new preparations are suitable for the pigmentation of high-quality lacquers and synthetic resins.

    Abstract: Pigment prepn. contains organic pigments (I) and basic additives, which are 1,3,6-trioxo- 1,3,6-trihydro- benzimidazo(2,1-b)benzo (1mn)(3,8)phenanthrolin-2-yl cpds. of formula (Q-A)xY (II), where Q = a gp. of formula (III), R1 = halogen, 1-4C alkyl, 1-4C alkoxy or CN; R2 = halogen; m and n = 0, 1, 2, 3 or 4; A = a chemical bond or a divalent -(CH2)p-, -CR3R4-, arylene, -S-, -O-or -NR5- gp. or a combination of these; p = 1-12; R3 and R5 = H or 1-6C alkyl; R4 = 1-6C alkyl; Y = a tert. N atom, -NR6R7, =NR8 or a satd. or unsatd. heterocyclic gp. and contains at least one tert. N atom; R6-8 = 1-20C alk(en)yl (opt. with hetero-atoms in the chain and/or terminal OH, prim. amino or acylamino gps.), a 5-6C cycloaliphatic or araliphatic gp. or an alkylene-heteroaryl gp.; x = 1-6. USE/ADVANTAGE - The prepn. is claimed for pigmenting high mol. organic materials and lacquer systems. It has much better dispersibility, flocculation stability, rheology, gloss and strength of colour than usual and is useful in plastic compsns., melts, spinning solns., lacquers, paints and printing inks.

    Abstract: Preparation of pigments, mixed crystal pigments or pigment preparations based on linear, optionally substituted quinacridones of formula (I) is by hydrolysing a cyclisation reaction mixture of a dianilinoterephthalic acid of formula (IA) and a polyphosphoric acid (or ester) with water or an aqueous mineral acid solution at 110 degrees C or above and then, depending on the nature of the product (A) directly isolating the pigment; (B) subjecting the pre-pigment to a finishing treatment, optionally after adding an organic solvent, and then isolating it; (C) finely dividing the coarse crystalline crude pigment and then isolating it; or (D) subjecting the finely-divided pre-pigment to a finishing treatment, optionally after adding a solvent, and then isolating it. In the formulae, R , R = H, Cl, Br or F or 1-4C alkyl, 1-4C alkoxy, carbonamido (optionally substituted by 1-6C alkyl) or a phenoxy- or aryl-ring optionally substituted by further aromatic, aliphatic or heterocyclic rings.
