PROCESS FOR PREPARATION OF A NOVEL PIGMENTED COMPOSITION FOR USE IN GRAVURE INKS |
摘要 |
The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially crude phthalocyanines) for use in publication gravure and packaging inks, wherein the crude pigment is dry-milled at relatively low temperature in combination with a resin and a pigment derivative, preferably further together with an extender and optionally an antioxidant. The invention also pertains to the thus obtained, new compositions, which are extraordinarily easily dispersible in aromatic solvents, and their use for the preparation of publication gravure or packaging inks or ink concentrates. Pigment dispersions obtained from the preferred compositions are also claimed. |
