Blocked leuco dyes for photothermographic elements |
abstract |
A photothermographic element containing a support bearing at least one heat-developable, photosensitive, image-forming photothermographic emulsion layer is provided. The emulsion layer comprises: (a) a photosensitive silver halide; (b) a non-photosensitive, reducible source of silver; (c) a leuco dye reducing agent; and (d) a binder; wherein the leuco dye reducing agent comprises a blocked leuco dye compound of the general formula L-R1, which is capable of being oxidized to a colored form, wherein: (i) L is a group remaining after removal of a hydrogen from a leuco dye; and (ii) R1 is a C(O)-NH-SO¿2-R?5 group wherein R5 is an aliphatic group or an aromatic group. |
