The present invention relates to a thermal donor comprising a dye mixture and a urea light-stabilizing compound, wherein the light-stabilizing compound is represented by structure I: wherein:

Urea stabilizers for thermal dye transfer materials

A print assembly including a dye-donor element and a receiver element, wherein the print assembly has a donor having a dye-donor layer having a first glass transition temperature and at least one dye, and a receiver having a dye-receiving layer having a second glass transition temperature on a support, wherein the print assembly has a receiver/donor dye partition coefficient of at least 2.5 when the print assembly is heated above the higher of the first or second glass transition temperature for a time sufficient to achieve an equilibrium state of dye distribution between the dye-donor layer and dye-receiving layer. The print assembly can be used at fast print speeds of 2.0 msec/line or less.

Thermal print assembly

A magenta dye combination having improved lightfastness and keeping properties is described, wherein the magenta dye combination can be used in thermal printing.

Photothermographic elements employing improved base precursors that undergo thermal decomposition are disclosed. Thermal-dye-bleach agents, and in particular, a novel class of salts of arylsulfonylacetic acids as bleaching agents for photothermographic use are disclosed. Photothermographic elements employing these thermal-dye-bleach agents are suitable for use as acutance and antihalation systems, bleachable filter dye materials, and in promoting unblocking of various components such as blocked developers, especially in photothermographic elements.
