标 题:Improved process for the production of printing inks
发明人：NIVEN STUART COOK; WILCOX JOYCE
权利人:CIBA SC HOLDING AG; NIVEN STUART COOK; WILCOX JOYCE
摘要:Process for preparing a polar organic solvent-based printing ink composition which comprises reacting a dye precursor of a cationic indole dye with an organic non-abietyl resin acid, preferably an organic sulfonic acid, in a polar organic solvent suitable for printing inks or in the printing ink medium. The synthesis of the coloured ink via an in-situ generation of the cationic dye offers many procedural advantages such the avoidance of isolation and purification steps for the dye. The printing inks obtained show for example high colour strength and excellent rheological properties and can be used in publication or packaging gravure flexographic, lithographic or letterpress printing processes.

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.

摘要:Organic pigments are conditioned by treating them, after synthesis but preferably without or with only partial drying, in a mixture of from 1 to 30% by weight of a neutral, polar 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 99% 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 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.
