标 题 :Manufacturing and conditioning of solid solution organic pigments
发明人：BUGNON PHILIPPE; MAURER MARC
权利人:CIBA SC HOLDING AG
摘要:Organic solid solution pigments are prepared and conditioned by treating a mixture of their components, after synthesis but preferably without or with only partial drying, in a mixture of from 0 to 30% by weight of an organic liquid having a dipole moment μ of 2.8–6.0·10 −18 .esu (2.8 to 6.0 debye units) and from 70 to 100% by weight of water in an agitated media pearl mill having a specific power density of at most 2.0 kj·s −1 per liter of grinding space. Drying the starting components is especially suitable in the case of only slightly agglomerating, easy to wet pigments of specific surface area from 1 to 25 m 2 /g. The method gives excellent results, and is flexible and also much simpler than known methods.

标 题 :Process for the preparation of high yield pigments
发明人：BAEBLER FRIDOLIN
权利人:CIBA GEIGY CORP
摘要:A process for the preparation of high yield pigments of the series of the diketopyrrolopyrroles, quinacridones, isoindolinones and isoindolines by protolysis of the pigment salt obtained by treating the crude pigment with a strong base or of the pigment salt obtained in the course of the synthesis, which process comprises treating said pigment salt, in an organic solvent, with water such that the organic solvent is simultaneously removed during the protolysis. The pigments so obtained are high yield pigments and have a particularly fine crystalline form and excellent purity.
