<p>Composition comprising (a) from 80 to 99.9 % by weight of an azo pigment (I) where M is Mg, Ca, Sr, Ba, or Mn or a mixture thereof, (b) from 0 to 20 % by weight of an azo pigment (II) (c) from 0 to 20 % by weight of an azo pigment (III) where R?1, R2 and R3¿ independently from each other stand for hydrogen, C¿1?-C20-alkyl, C5-C20-alkoxy, C2-C20-alkenyl, C1-C20-akylthiol, C1-C20-alkoxycarbonyl, hydroxy-C1-C4-alkoxy, phenyl, benzyl, phenylthio, halogen, such as fluoro, chloro, bromo, iodo, cyano, nitro, -CF3, -COR?4, -COOR5, -CONR4R5, -SO¿2R4, -SO2NR?4R5 -NR4R5, -NR4R5 or -OR4¿, with the proviso, that when R2 stands for hydrogen and R3 is CF¿3?, then R?1¿ is not -SO¿3?, and wherein R?4 and R5¿ independently from each other stand for hydrogen, C¿1?-CX4-alkyl or phenyl, with the proviso, that at least one of the groups R?1, R2 or R3¿ is not hydrogen, preferably wherein R1 is -COOH or -SO¿2?H, (a) from 0 to 20 % by weight of an azo pigment (IV) (e) from 0 to 20, preferably 0.1 to 20 % by weight, based on the sum of the amounts of components (a) to (d), of surfactant, (f) from 0.1 ot 50 % by weight, based on the sum of the amounts of components (a) to (d), of a resin selected from the group consisting of tall oil resin, gum rosin, wood rosin, hydrogenated rosin ester, disproprotionated rosin, dimerised rosin, polymerised rosin, phenolic rosin and carboxyl containing maleic and fumaric resin, a process for its preparation, its use for the preparation of dispersions, paint systems, coating materials, color filters, inks, preferably printing inks, as well as color toners comprising the inventive pigment compositions, particularly preferable as liquid inks in the packaging industry, and liquid inks for the packaging industry.</p> |
