Abstract
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.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·sper 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/g. The method gives excellent results, and is flexible and also much simpler than known methods.
