  • Patent number: 8076394
    Abstract: Compositions and methods for printing on specialty media are disclosed. The methods comprise the steps of providing a fixing fluid, providing a dye- or pigment-based ink-jet ink containing an effective amount of a polyvinyl(alcohol-acetate) species, jetting the fixing fluid onto the specialty media forming a coated substrate, and jetting the ink-jet ink onto the coated substrate. Additionally, a gelled printed image on a substrate is disclosed comprising a fixing fluid containing a fixing agent and an aqueous ink-jet ink containing a polyvinyl(alcohol-acetate) species. In both the method and with respect to the image, the polyvinyl(alcohol-acetate) species used can be a known species, or one of a number of new graft copolymers containing a polyvinyl(alcohol-acetate) polymer as one of the constituents of the copolymer.

  • Patent number: 8067483
    Abstract: Indicator inks, indicators formed by printing or otherwise utilizing the inks and host products utilizing the indicators are disclosed. Reactivity-enhancing adjuvants stimulate enhanced thermal reactivity of diacetylenic or other indicator agents capable of responding to ambient thermal conditions with a visual change signaling an end point. The diacetylenic or other agents may be sensitive or relatively insensitive to ambient temperatures. Use of a reactivity-enhancing adjuvant provides a useful means for adapting the reactivities of indicator agents to the response characteristics of prospective host products, for example perishables such as vaccines or fresh fish and maturables such as fruit, cheese and wine. Some exemplary adjuvants include low-temperature polymerization initiators, for example methyl ethyl ketone peroxide and polymerization accelerators, for example cobalt compounds. Such initiators and accelerators can also be used in combination.
