Abstract: The disclosure relates to circuits and methods for the manufacture of circuits, such as those which avoid the formation of undesirable short circuit paths. One such method maintains a layout area of a fluid composition receiving layer within a layout area of a dielectric layer. Another such method relates to the application of fluid composition receiving layers, conductive layers, and dielectric layers, such as in the provision of printed circuits.

Abstract: Printed circuits having conductive traces applied adjacent to a substrate, such as one where the traces have a resistivity of from about 1 to about 0.1 ohms/square, and methods for forming a fluid composition receiving layer adjacent to a substrate. One such method includes depositing a primary treatment fluid having a particle dispersion and a binder in a carrier fluid adjacent to at least a portion of a substrate to provide a treated substrate having a fluid composition receiving layer. The primary treatment fluid is deposited in a pattern using a: micro-fluid ejection head. After deposition, the carrier fluid content of the fluid composition receiving layer is reduced.

Abstract: Methods for improving adherence of conductive traces, such as in a printed circuit, and circuits having conductive traces formed in accordance with such methods. One such method includes depositing a fluid composition receiving layer adjacent to a substrate, and depositing a gradient layer adjacent to the fluid composition receiving layer. The gradient layer is comprised of a fluid composition providing the fluid composition receiving layer and a fluid composition providing a conductive layer. A conductive layer composition is deposited adjacent to the gradient layer to provide the conductive layer.

Abstract: Printing systems such as those comprising a printing device operable for depositing one or more inks upon a substrate and a drying device, such as one operable for emitting radiation having a pre-selected electromagnetic wavelength, for the purpose of drying the one or more inks in a predetermined time period subsequent to the deposition of the one or more inks upon the substrate, wherein the printing device and the drying device are operated at about the same moving speed. Methods of printing, such as those comprising depositing one or more inks onto a substrate using a printing device and drying the one or more deposited inks using a drying device, such as one operable for emitting pre-selected wavelengths of energy that are focused onto the one or more deposited inks in a predetermined time period subsequent to ink deposition, wherein the depositing and the drying are synchronized.

Abstract: Thermal inkjet inks having at least about 5 percent by weight pigment, a dispersant having moieties of methacrylic acid, poly(propylene glycol)-4-nonylphenyl ether acrylate and poly(ethylene glycol) 2,4,6-tris-(1-phenylethyl)phenyl)ether methacrylate; a humectant and a surfactant, preferably ethoxylated 2,4,7,9-tetramethyl 5 decyn-4,7-diol.

Abstract: An ink set of at least four colors includes a high density cyan (C), a low density cyan (c), or a high density magenta (M), or a low density magenta (m), or both the cyans and magentas, and a high density yellow comprising Pigment Yellow 74, and a low density yellow comprising Pigment Yellow 155. The low density inks may be in a single cartridge having three, separate ink compartments, as is known for three color inks. Similarly, the high density inks may be in separate compartments of another cartridge. A third cartridge may contain other inks such a high density or low density black. In printing by the foregoing ink set for photographic quality the low density yellow ink may be favored, which provides maximum resistance to fade, while the high density ink is used as desired for more vibrant images.

Abstract: This invention relates to polymeric dispersants useful in ink jet ink compositions. The graft polymers comprise monomers having electron rich functional groups, which exhibit favorable interactions with the surface of pigment particles thereby better stabilizing the pigment dispersion within the aqueous ink composition. The graft polymers also comprise hydrophobic monomers having the ability to form hydrogen bonding. The polymers of the present invention provide a dispersant that increases the smear resistance of pigmented inks, especially when used on photo or gelatin paper. The graft polymers also provide excellent chroma for printing. The present invention also relates to aqueous ink compositions which include those polymeric dispersants.
