Summary: | Disclosed herein are compositions comprising a dimeric (diarylide) pigment and a synergist, in which the synergist has a structure similar to a monomer of the dimeric pigment. Also disclosed are aqueous dispersions and inkjet inks comprising such compositions. In a first preferred composition, the symmetric diarylide pigment has the following structure: (P-1) and the synergist has the following structure: (S-1). In a second preferred composition, the symmetric diarylide pigment has the following structure: (P-2) and the synergist has the following structure: (S-2).
L'invention concerne des compositions comprenant un pigment dimère (diarylide) et un synergiste, le synergiste ayant une structure similaire à un monomère du pigment dimère. L'invention concerne également des dispersions aqueuses et des encres pour jet d'encre comprenant de telles compositions. |
