  • Patent number: 7691920
    Abstract: An ink jet ink includes an ink vehicle, wherein the ink vehicle includes at least one wax monomer functionalized to include in the chain at least one reactive group curable upon exposure to radiation. The reactive group is preferably curable via cationic or free radical polymerization. In a preferred embodiment, the ink vehicle includes a wax monomer having a structure: wherein C represents a cationically curable group and R represents a radically curable group. The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.

  • Patent number: 7691958
    Abstract: A polypropylene for an electric material has a melt flow rate of 0.1 to 30 g/10 min., a mesopentad fraction calculated from a 13C-NMR spectrum of 0.90 to 0.99, and a firing residue of 50 ppm by weight or less based on the polypropylene, a titanium content and an iron content which are detected from the firing residue, of 1 ppm by weight or less and 0.1 ppm or less, respectively, based on the polypropylene, and the chlorine content of 5 ppm by weight or less based on the polypropylene. The above polypropylene exhibits excellent electric insulation and has a roughened surface when it is formed into a film, and thus the polypropylene can be suitably used for a capacitor film without using an additive such as a ? crystal nucleating agent. The polypropylene is also useful as a material of a film for coating an electric wire and a material for an instrument for conveying an electronic material.

  • Patent number: 7691961
    Abstract: A polyimide film in which the dimensional change is reduced when it has undergone a step of laminating a metal on the polyimide film or a step of etching the metal layer to form wiring, and the rate of dimensional change can be stabilized across the entire width is provided. The object can be solved by a polyimide film produced by a continuous process, wherein when a coefficient of linear expansion a in a direction of the molecular orientation axis and a coefficient of linear expansion b in a direction perpendicular to the molecular orientation axis are measured in the temperature range of 100° C. to 200° C., a and b satisfy a particular relationship across the entire width, or a polyimide film produced by a continuous process, wherein when a tear propagation resistance c in the direction of the molecular orientation axis and a tear propagation resistance d in the direction perpendicular to the molecular orientation axis are measured, c and d satisfy a particular relationship across the entire width.

  • Patent number: 7691967
    Abstract: The present invention relates to prodrugs of protease inhibitors, such as inhibitors of proteosome, DPOP IV, FAP? and the like. These “pro-inhibitors” are activated, i.e., cleaved by an “activated protease” to release an active inhibitor moiety in proximity to a “target protease”. The identity of activating protease and target protease can be the same (such pro-inhibitors being referred to as “Target-Activated Smart Protease Inhibitors” or “TASPI”) or different (e.g., “Target-Directed Smart Protease Inhibitors” or “TDSPI”). After activation of the pro-inhibitor, the active inhibitor moiety can self-inactive by, e.g., intramolecular-cyclization or cis-trans isomerization.
