ABSTRACT:
A process for preparing a modified particulate solid comprising reacting a dispersant with a compound in the presence of a particulate solid and a liquid medium, characterised in that:a) the dispersant has at least one reactable group selected from keto, aldehyde and beta-diketoester groups,b) the compound has at least two groups reactive towards said keto, aldehyde and/or beta-diketoester groups.The process provides a modified particulate solid having improved stability which is particularly useful for liquid vehicles having and range of polarities and for incorporation into ink jet printing inks.
