Abstract: derivs. of formula (where R = satd. 1-18C alkyl in which 1 or 2 H atoms can be substd. by OH, Cl, Br, N-N-dialkylamino with a total of 1-4C; or 1-8C alkoxy; satd. 5-8C mono- or bicycloalkyl or a phenalkyl gp. with 1-8C in the alkylene gp. and in which the Ph gp. may be substd. by Cl, Br, Me, Et, OH or 1-4C alkoxy). The cpds. are used in printing colours and may be prepd. by reaction of imino cpd. with prim. amines of formula R-NH2 at room temp. to 120 degrees C.

Abstract: Process for the preparation of liquid formulations of basic azo dyes comprising m-phenylenediamine which is optionally substituted by C1-C4-alkyl or C1-C4-alkoxy, by diazotisation and coupling in a solution containing carboxylic acid, the reaction being carried out using from 0.76 to 0.95 mol of nitrite, calculated as nitrous acid, per mole of m-phenylenediamine, and the resulting reaction mixture being heated subsequently to a temperature of from 60@C to the boiling temperature of the reaction mixture.

Abstract: Polyhalocopper phthalocyanine pigments of high color strength are prepared by recrystallizing the finely divided agglomerated crude pigment in a heterogeneous aqueous organic phase at elevated temperatures by a process in which the aqueous organic phase used is a heterogeneous mixture of an aliphatic ketone having a total of 3 to 9 carbon atoms and water. The process gives the pigments in the form of spherical granules which are dust-free or have a low dust content. The pigments give deep, brilliant colorations of pure hues.

Abstract: Highly concentrated and stable solutions of esterified rhodamine dyes of formula (A) and/or (B) in which R is H, acetyl, propionyl or 1-4C alkyl, or a radical of formula: (CH2CH2O)nR2; n is 1 or 2; R' is H, CH3 or C2H5; and R2 is H, acetyl, propionyl or 1-4C alkyl. For dyeing paper in aqueous baths, and in printing inks. Solutions from the mixed dyes A and B give good shades when dyeing paper, while solutions from dye A give good printing ink colours. The solutions may contain dye A only, or A and B in the ratios of 40 to 60: 60 to 40. The solutions are prepared by esterifying the bases corresponding to the dyes A and B with dialkyl sulphate and/or polyglycol ethers and heating subsequently to 100 degrees-200 degrees C.

Abstract: Completely esterified rhodamine dyes of the formula where R, R2 and R4 are independently of one another methyl or ethyl, R1 and R3 are independently of one another hydrogen, methyl or ethyl, R5 and R6 are independently of one another hydrogen or methyl and A(-) is an anion, are prepared from compounds of the formula II or from the corresponding water addition products by esterification with dialkyl sulfates in solvents by using gamma -butyrolactone, alkylene carbonates, dialkyl carbonates, methoxypropyl acetate or dialkyl phthalates as solvent and working in the presence of an excess of a base, based on dialkyl sulfate.

Abstract: Salts of esterified rhodamine dyes are prepared in granular form by precipitating the rhodamine dyes with sodium chloride from an aqueous medium containing a water-miscible solvent by adding the sodium chloride at 80 DEG -100 DEG C., which precipitates the dyes in liquid form from the aqueous medium, then stirring the liquid dyes to convert them into a droplet form and then chilling the droplets by direct cooling to below 65 DEG C.
