摘要: The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially phthalocyanines) use in offset inks, wherein high amount of resin is used, at least part which low molecular phenol-modified rosin, an esterified rosin or hydrocarbon similar properties, preferably together with antioxidant, and performed relatively temperature. also the thus obtained, new compositions, are extraordinarily easily dispersible solvents, their preparation inks ink concentrates. Pigment dispersions obtained from preferred compositions claimed.
