MANUFACTURING AND CONDITIONING OF SOLID SOLUTION ORGANIC PIGMENTS |
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 ~ 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 mil l having a specific power density of at most 2.0 kj.s-1 per litre 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 m2/g. The method gives excellent results, and is flexible and also much simpler than known methods.
