ABSTRACT:
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:R1, R2and R3represent a hydrogen atom, alkyl group, cycloalkyl group, alkenyl group, aralkyl group, aryl group or heterocyclic group, provided that at least one of R1, R2, and/or R3is a hydrogen atom; R4-R8represent a hydrogen atom, hydroxyl group, alkyl group, cycloalkyl group, alkenyl group, aralkyl group, aryl group, heterocyclic group, aryloxy group, or alkoxy group; and R3forms a heterocyclic ring with either R4or R8, and an imaging system comprising a donor sheet having a layer containing a dye and an image receiving sheet having a dye receiving layer, wherein either the donor sheet or the image receiving sheet comprises a dye mixture and a urea light-stabilizing compound of structure I.
