摘要： The present invention is directed to a photothermographic element comprising silver halide, a blocked developer, a coupler, and core/shell particles, each such particle comprising a mixture of at least two non-photosensitive organic silver salts, which particle comprises a center portion comprising a non-photosensitive first organic silver salt and at least one shell portion covering the center portion, the shell comprising a non-photosensitive second organic silver salt. The organic silver salt in the shell has a higher pKsp relative to the organic silver salt in the core. This invention also provides a composition comprising core/shell non-photosensitive organic silver salt particles, and a method of making the particles.

摘要： A recyclable continuous ink jet print head is provided that includes a manifold formed from a metal such as stainless steel, a die having ink jet nozzles formed from a ceramic material such as silicon, a control circuit connected to the die via microwiring, and an interposing member disposed between the manifold and the die. The interposing member is formed from a composite material such as Al—SiC having a coefficient of thermal conductivity that is higher than that of the silicon die, and a coefficient of thermal expansion (CTE) that is between that of the die and the manifold. During manufacture, the CTE value of the interposing member allows long-lasting, heat-cured epoxy compositions to be used to bond the die to the manifold and to encapsulate the microwiring between the die and a control circuit with while maintaining proper alignment of the die ink jet nozzles on the manifold. When the die wears out, the high thermal conductivity of the interposing member allows the die to be easily removed from the manifold, thereby facilitating re-cycling of the manifold.
