  • Patent number: 8591278
    Abstract: A method of manufacturing a PDP bus electrode comprising steps of: (a) applying onto a glass substrate a black paste comprising, based on the weight of the black paste, (i) a black colorant, (ii) a first glass frit having a first softening point, (iii) a second glass frit having a second softening point, (iv) a photopolymerization initiator, (v) a photopolymerizable compound, and (vi) an organic medium; (b) applying onto the applied black paste a white paste comprising a metal powder, glass frit and an organic medium; (c) exposing the applied pastes to light; (d) developing the exposed pastes; and (e) firing the developed pastes with a firing profile having a firing peak temperature, wherein the first softening point is lower than the firing peak temperature and wherein the second softening point is higher than the firing peak temperature.

  • Patent number: 7928322
    Abstract: Disclosed is an active energy ray-curable conductive ink containing a conductive substance and a binder component, which is characterized in that the binder component contains a chlorinated polyester and an active energy ray-polymerizable compound. This active energy ray-curable conductive ink has good fluidity and enables to obtain a conductive circuit with low resistance after curing. Also disclosed are a method for forming a conductive circuit by printing this conductive ink on a substrate, and non-contact media comprising an IC chip mounted in a state electrically connected with the conductive circuit. The conductive substance is preferably a flake powder having a BET specific surface area of 0.1-0.4 m2/g and an aspect ratio of not less than 3.
