摘要: This invention is concerned with dispersions of solids in organic liquids containing polymeric or resinous dispersing agents. The fluidity of such dispersions is greatly improved by the presence in the dispersions of a substituted ammonium salt of a colored acid wherein there are between 16 and 60 carbon atoms contained in at least 3 chains attached to the N-atom of the substituted ammonium ion. The dispersions are particularly useful for the preparation of ink and paints.
