International ClassesC09D 11/02B41M 5/00 AbstractAnti-bronzing compounds are added to inkjet inks to prevent bronzing of the inks when printed on specialty quick-dry inkjet photographic media. These compounds inhibit bronzing by the proper buffering of the dyes relative to the media of interest.Field of SearchOrganic dye containingPigment containing Organic nitrogen compound containing Organic nitrogen compound containing Organic oxygen compound containing Organic oxygen compound containing Six-ring members in the heterocyclic ring Six-ring members in the heterocyclic ring Particles in recording layer Particles (e.g., pigment, etc.) present in ink receptive layer | |
