Abstract: IMPROVED PROCESS FOR THE PREPARATION OF PUR 4-BROMO3-HYDROXY-QUINOPHTHALONE, WHEREIN 3-HYDROXY-QUINOPHTHALONE IS REACTED WITH BROMINE IN SULFURIC ACID OF 96 TO 100 PERCENT STRENGTH AT A TEMPERATURE BETWEEN ABOUT 0* AND 40*C. THE PRODUCT SO OBTAINED DYES POLYESTER MATERIALS EVEN YELLOW TINITS INDEPENDENT OF THE PH-VALUE OF THE DYEING MEDIUM AND WITHOUT UNDESIRED DEPOSITS ON THE MATERIAL TO BE DYED. MOREOVER, THE DYESTUFF IS OBTAINED IN PURE FORM SO THAT SUBSEQUENT PURIFICATION IS NOT NECESSARY.

Abstract: Pigment compositions of resins and xanthene dyestuffs, which are prepared by dissolving the dyestuff salt with the addition of alkali in an organic solvent miscible with water or in an organic amine, dissolving in this solution such a resin which can be precipitated again by addition of an acid, or adding such a solution of such a resin in one of the said solvents, mixing the mixture thus obtained with an aqueous acid and recovering the pigment composition precipitated. The pigment compositions according to the invention are distinguished by an extraordinary good brilliance of the prints produced therewith. They are extremely easy to disperse in printing varnishes and therefore especially valuable in use.

Abstract: A process for preparing very pure copper phthalocyanine pigments of the alpha -modification, wherein substituted or unsubstituted copper phthalocyanines having different degrees of purity are converted into copper phthalocyanine salts capable of being isolated, with the aid of suitable acids which dissolve the impurities contained in the dyestuff, wherein these salts are separated from the acid, the copper phthalocyanines of the alpha -modification are set free in a pure form from the copper phthalocyanine salts by the action of water and wherein the isolated copper phthalocyanine is subject in an aqueous suspension to a mechanical fine division. This process yields copper phthalocyanines of the alpha -modification in a very pure form without causing problems with respect to the waste water.

Abstract: Polyhalo copper phthalocyanines are obtained by reacting a di- to tetrahalo phthalic acid or a derivative thereof, if necessary urea, a copper salt, a titanium tetrahalide and a compound capable of forming an addition compound with said titanium tetrahalide. The purification of the so-obtained products is much easier since lower amounts of titanium compounds can be used. The products are useful as pigments.
