ABSTRACT:
This invention concerns a composition for use as an additive in an ink composition for an inkjet printer or a laserjet printer or as a coating on paper or plastic substrate used in an inkjet or laserjet printer which improves lightfastness and durability properties of the ink, which additive composition comprises: (A) at least one ultraviolet absorber, (B) at least one free radical inhibitor, (C) at least one antioxidant, and (D) at least one liquid carrier selected from the group consisting of water, organic liquid or combinations thereof. These compositions result in a print image that is more colorfast and durable than those of the conventional art.
