摘要:Process for preparing a polar organic solvent-based printing ink composition which comprises reacting a dye precursor of a cationic indole dye with an organic non-abietyl resin acid, preferably an organic sulfonic acid, in a polar organic solvent suitable for printing inks or in the printing ink medium. The synthesis of the coloured ink via an in-situ generation of the cationic dye offers many procedural advantages such the avoidance of isolation and purification steps for the dye. The printing inks obtained show for example high colour strength and excellent rheological properties and can be used in publication or packaging gravure flexographic, lithographic or letterpress printing processes.

摘要:The invention describes a process for the preparation of granular dye formulations by melt granulation, using a polyethylene glycol as melt vehicle. The essential feature of the invention is that a start is made from the dye which contains water, for example from the aqueous filter cake or synthesis solution, and adjusting the moisture content of the granular formulations to 1 to 30% by partial evaporation of water from the dye/polyethylene glycol melt.
