Abstract:
1. A process comprising: a) depositing from a dispensing orifice a reservoir of a deposit composition comprising between 0.1 and 70 percent by weight of functional phase particles and a viscoelastic polymer solution comprising an ultrahigh molecular weight polymer having a molecular weight greater than 1,000,000 which is soluble in a dispersing vehicle onto the surface of a substrate; b) contacting said reservoir with a needle or spinnerette wet by the composition; c) drawing a fiber from said reservoir by removing needle or spinnerette from the reservoir and away from the surface of said substrate; d) translating the finely pointed object to an other point above the substrate such that said fiber extends between said reservoir and said other point; e) depositing that fiber between said reservoir and another point on the substrate by contacting the needle or spinnerette to the substrate at that point; f) evaporating the dispersing vehicle from the deposited fiber resulting in the functional phase particles being affixed to the substrate in an image and g) optionally heating the substrate and deposited fiber to a temperature sufficient to effect removal of organic components.
