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 - 6Ø10-18.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 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.

Selon cette invention, des pigments organiques en solution solide sont préparés et conditionnés par traitement d'un mélange de leurs constituants après synthèse, mais de préférence sans séchage ou avec séchage partiel uniquement, dans un mélange comprenant de 0 à 30 % en poids d'un liquide organique possédant un moment dipolaire ? de 2,8 6,0.10?-18¿ esu (2,8 à 6,0 unités de Debye) et de 70 à 100 % en poids d'eau dans un broyeur à billes à milieu agité possédant une densité calorifique spécifique d'au plus 2,0 kJ.s?-1¿ par litre d'espace de broyage. Le séchage des constituants de départ est spécialement adapté dans le cas de pigments ne s'agglomérant que faiblement, faciles à mouiller, d'une surface utile spécifique comprise entre 1 et 25 m?2¿/g. Ce procédé donne d'excellents résultats, est souple et également considérablement plus simple que les procédés connus.
