Abstract
A process for converting a pigment or disperse dye into another modification by treating the colorant with a liquid alkylamine and removing the treatment agent by evaporation after the conversion into the modification. The pigments afforded by the instant process are used in the same way as the untreated colorants for pigmenting materials of high molecular weight.
