Metal compositions, thermal imaging donors and patterned multilayer compositions derived therefrom

A multilayer thermal imaging donor comprising:

• a base film, a metal transfer layer, and a LTHC layer interposed between said base film and said metal transfer layer;
• wherein said metal transfer layer has thickness of about 0.2 to about 3 microns and comprises a metal composition (A) comprising about 65 to about 95 wt % of a metal powder selected from the group consisting of:
• Ag, Cu and alloys thereof;
• comprising a plurality of metal particles characterized by an average longest dimension of about 5 nm to about 1500;
• and about 5 to about 35 wt % of a dispersant comprising one or more resins selected from the group consisting of:
• conducting polymers selected from the group consisting of:
• polyaniline, polythiophene, polypyrrole, polyheteroaromatic vinylenes, and their derivatives;
• and nonconducting polymers selected from the group consisting of:
• acrylic and styrenic-acrylic latexes and solution-based acrylic and styrenic-acrylic (co)polymers;
• and combinations thereof;
• copolymers of ethylene with one or more monomers selected from the group consisting of:
• (meth)acrylate(s), vinyl acetate, carbon monoxide and (meth)acrylic acid;
• and polyvinylacetate and its copolymers further comprising one or more additional transfer layer(s) wherein the one or more additional transfer layer(s) comprises a conducting polymer selected from the group consisting of:
• polyaniline, polythiophene, polypyrrole, polyheteroaromatic vinylenes, and their derivatives, wherein the one or more additional transfer layer(s) comprises a conducting layer selected from the group consisting of:
• polyaniline and derivatives thereof;
• and further comprises 0.1 to 12 wt % single wall carbon nanotubes and an organic protic acid having 1 to 30 carbons, said acid present at a molar equivalent amount of about 25% to about 100% of the nitrogen atoms in the polyaniline backbone.
