Abstract: A color former composition which is composed of a mixture of the color formers 3-diethylamino-6-methyl-7-(2′,4′-dimethylanilino)fluoran and 3-dibutylamino-6-methyl-7-anilinofluoran in defined amounts. Further compositions contain mixtures of color formers including one or both of these fluoran compounds and the color formers 3-dibutylamino-6-methyl-7-anilinofluoran and/or 3-diethylamino-6-methyl-7-(3′-methylanilino)fluoran. Microcapsules containing the color former compositions can be prepared from a composition which also contains an organic solvent and can be used to prepare a pressure sensitive or thermal recording material. The mixture of color formers can provide a higher concentration in various organic solvents and/or can be used with less expensive solvents.
