Abstract
The abrasiveness of a pigment or printing ink is reduced by incorporation of one or more finely divided substances which are insoluble in printing inks and have a Mohs hardness of from 4.5 to 8, suitable compounds being iron powder, compounds of iron, zirconium, silicon and magnesium, aluminum silicates, oxides of manganese, tin and cerium, or mixtures of these. The printing inks obtained cause substantially less, or virtually no, abrasion of gravure printing cylinders.
