Abstract:
Ink compositions are prepared by processes that include acoustically mixing a plurality of components at a resonance frequency. This encourages mixing of the components over a large range of viscosities with a minimal temperature rise and also shortens mixing time.
Abstract:
Disclosed herein are ink compositions comprising at least one hyperbranched oligomer present in an amount ranging from about 3% to about 20% and having a functionality ranging from about 6 to about 40; at least one pigment present in an amount of at least about 10%; and at least one photoinitiator present in an amount ranging from 5% to 10%. Further provided herein are methods of printing using a variable data digital lithographic printing device.
Abstract:
A nanosilver ink composition including silver nanoparticles; a clay dispersion; and an ink vehicle. A process for forming conductive features on a substrate includes providing a nanosilver ink composition comprising silver nanoparticles; a clay dispersion; and an ink vehicle; depositing the nanosilver ink composition onto a substrate to form deposited features; and heating the deposited features on the substrate to form conductive features on the substrate.
Abstract:
