| 摘要 |
<p>The present invention is a heat developed, photothermographic element comprising a support bearing at least one photosentitive, image-forming photothermographic emulsion layer comprising: (a) a photosensitive silver halide; (b) a non-photosensitive, reducible silver source; (c) a reducing agent for silver ions; (d) a binder; and (e) a substituted hydroxyphenyl compound which provides antifoggant and print stabilizing properties to the photothermographic element. The substituted hydroxyphenyl compound may be of formula (I), wherein R represents hydrogen, benzoyl, a five or six membered heterocyclic ring system, or a fused ring system; or of formula (II) wherein: R1 represents a disubstituted or a trisubstituted s-triazine group, a disubstituted benz-bis-triazole group, a disubstituted benz-bis-thiazole group, a disubstituted benz-bis-oxazole group, and a disubstituted benz-bis-immidazole group.</p> |
