Abstract: An ink transfer sheet and method for using the same. The transfer sheet includes a backing layer, a release layer on the backing layer, and an ink receiving layer on the release layer. The ink receiving layer contains a quaternary ammonium salt thereon or impregnated therein. To use the transfer sheet, an ink containing an anionic coloring agent is applied to the ink receiving layer, preferably using thermal inkjet methods. Thereafter, the transfer sheet is positioned on a fabric substrate. Heat is applied to the sheet which causes the release layer and ink receiving layer to adhere to the substrate. The backing layer is then detached from the release layer leaving the release and ink receiving layers (with the printed image thereon) on the substrate. This process transfers the image to the fabric substrate, with the image being stabilized by interactions between the quaternary ammonium salt and anionic coloring agent.

Abstract: An ablatable laminar imaging medium useful in the manufacture of a substantially transparent electrode assembly is disclosed. The laminar imaging medium comprises a substrate, a high-index metal oxide layer, an ablatable metallic conductive layer, a high-index conductive metal oxide layer, and an ablation enhancement layer. The ablation enhancement layer has an IR-absorption greater than the IR-absorption of said high-index conductive metal oxide layer and an IR-reflectivity less than the IR-reflectivity of said high-index conductive metal oxide layer. Presence in the laminar imaging medium of the ablation enhancement layer lowers the exposure threshold of the medium and improves ablation accuracy, both—when occasioned in the manufacture of LCD electrode patterns—resulting collectively and ultimately in a more reliably formed electrical architecture, less susceptible to unwanted “shorting”.

Abstract: A method of glass frit bonding wafers to form a package, in which the width of the glass bond line between the wafers is minimized to reduce package size. The method entails the use of a glass frit material containing a particulate filler material that establishes the stand-off distance between wafers, instead of relying on discrete structural features on one of the wafers dedicated to this function.

To accommodate the variability associated with screening processes when low volume lines of paste are printed, the invention further entails the use of storage regions defined by walls adjacent the glass bond line to accommodate excess glass frit material without significantly increasing the width of the bond line.
