Beschreibung
Zusammenfassung:	This invention relates to a dispersing agent for use in dispersing a finely divided solid powder in a nonaqueous dispersion medium and a dispersion prepared by using the dispersing agent. The dispersing agent of this invention is a low acid value lanolin fatty acid and/or a salt of the same. By means of this dispersing agent, there can be easily obtained a homogeneous and stable nonaqueous dispersion from which the incorporated solid particles will not separate out or settle even on prolonged standing. Therefore, this dispersing agent can be used advantageously in a broad range of applications such as coatings, dyes, pigments, inks, fuels, lubricating materials and so on.
