Pigment compositions suitable for oil-based lithographic printing inks are provided which comprise besides an organic pigment, a hyperdispersant which is a poly-alkyleneiminepolyester adduct, a synergist agent which is a quaternary ammonium pigment derivative, a solvent which includes aliphatic/aromatic hydrocarbon distillates and vegetable oils, and optionally rosin or a modified rosin. The printing inks prepared from these pigment compositions show outstanding improvements in their rheological properties.
L'invention concerne des compositions pigmentaires pouvant être utilisées dans des encres d'impression lithographique à base d'huile, qui comprennent, outre un pigment organique, un produit hyperdispersant qui est un produit d'addition poly-alkylèneiminepolyester; un agent synergique qui est un dérivé de pigment d'ammonium quaternaire; un solvant qui comprend des distillats d'hydrocarbures aliphatiques/aromatiques et des huiles végétales; et éventuellement de la colophane ou une colophane modifiée. Les encres d'impression préparées à partir de ces compositions pigmentaires présentent des propriétés rhéologiques améliorées de façon exceptionnelle.
