Abstract: A process for purifying crude organic pigments, wherein the crude pigment is suspended in a mixture of two organic liquids which are partially or completely immiscible with one another, the suspension is mixed at 50 DEG -180 DEG C. until equilibrium has been reached, the phases are allowed to separate, the phase containing the impurities (i.e. the first liquid) is separated off and the purified pigment is isolated from the other phase (i.e. the second liquid). Finely divided crude pigments can, directly after purification, be converted, while in the second liquid, into pigmentary forms. The process gives pigments of high purity, which after conversion into pigmentary forms give deep, brilliant colorations.

Abstract: A process for converting crude copper phthalocyanine to a pigmentary form, wherein finely divided and heavily agglomerated crude copper phthalocyanine which exhibits disturbed crystallization and which has a primary particle size of less than 0.1 mu um is introduced into an organic or aqueous organic medium together with from 0.5 to 7% by weight, based on the crude copper phthalocyanine, of a basic copper phthalocyanine of the formula (I) or (II) or of mixtures thereof (where CuPc is an n-valent copper phthalocyanine radical, R1 is H or alkyl of 1 to 4 carbon atoms, A is linear or branched alkylene, R2 is alkyl of 1 to 20 carbon atoms, alkoxyalkyl of 3 to 12 carbon atoms or cycloalkyl of 6 to 8 carbon atoms, R3 is H, alkyl of 1 to 4 carbon atoms or cycloalkyl of 6 to 8 carbon atoms or is a saturated heterocyclic 5-membered, 6-membered or 7-membered ring, and n is an integer from 1 to 6), and the suspension is heated at from room temperature to 180 DEG C until the pigment exhibits optimum tinctorial strength. Pigments of high tinctorial strength, which give colorations having a pure hue, are obtained.

Abstract: A procedure and apparatus for charging and emptying the drying trays in a drying box containing pumpable, solvent-moist starting materials and end products which can be conveyed pneumatically, in which procedure, for filling, the drying trays are closed by means of cover plates and the solvent-moist starting materials are pumped into the filling spaces which are thus formed, these spaces being opened on commencing the drying process, and being closed again following completion of this process, after which the end products are conveyed away from the filling spaces by pneumatic means. This procedure enables drying boxes to be employed for drying even pumpable, solvent-moist products, the recommendations relating, respectively, to explosion protection and to maximum permissible concentrations of toxic materials at workplaces, being complied with, while the operations of charging and emptying the drying boxes are, at the same time, carried out by mechanical means, and hence at lower cost.

Abstract: Stable, fluid formulations contain (a) finely divided iron cyano complexes, iron-III oxides or iron-III oxide hydrates, (b) one or more C6-C18-alkylbenzenesulfonic acid, (c) one or more compounds which are obtained by Mannich condensation from 2-hydroxynaphthalene, which may or may not contain 1 or 2 additional beta -hydroxyl groups, formaldehyde and primary or secondary aliphatic, cycloaliphatic or aromatic monoamines, diamines, triamines or polyamines or 5- or 6-membered heterocyclic compounds, and which contain from 1 to 6 beta -hydroxynaphthyl groups, and (d) one or more organic liquids, the ratio of (b):(c) being from 1:8 to 2:1 and the amount of (c) being from 10 to 20% by weight, based on (a). The formulations are fluid or pourable at pigment concentrations of from 20 to 55% by weight and give very deeply colored, very glossy finishes.

Abstract: Readily dispersible formulations comprising (a) finely divided copper phthalocyanine and (b) an iron hexacyanoferrate-III pigment are obtained by thoroughly milling a mixture of (a) and (b). The performance characteristics and tinctorial properties of the formulations comprising (a) and (b) can be improved by incorporating (c) a Mannich condensate obtained from 2-hydroxynaphthalene which may or may not possess 1 or 2 further beta -OH groups, formaldehyde and a primary or secondary amine, (d) a compound of the formula K(-NH-CONH-R)2, where K is 1,5-naphthylene or 4,4'-diphenylenemethane and R is C12-C18-alkyl, C12-C18-alkenyl, C8-C18-alkoxypropyl or C2-C8-alkoxyethyleneoxypropyl, (e) a C6-C18-alkylbenzenesulfonic acid and (f) a mixture of (e) with a basic copper phthalocyanine and/or a salt obtained by reacting (e) with the basic copper phthalocyanine. The finishes and printing inks produced using the formulations have tinctorial properties and performance characteristics which are superior to those of finishes and inks obtained by mixing individually milled or dispersed components.
