摘要： The present invention is directed to a method of forming a positive image in a photothermographic element comprising a potentially negative-working emulsion wherein fog density development is imagewise inhibited in exposed areas of the image upon thermal development. In one embodiment of the invention, a density-inhibiting agent is released during thermal development which agent inhibits the thermal development of unexposed silver salts in the exposed areas relative to the unexposed areas. The method preferably comprises imagewise exposing the film with a non-solarizing amount of radiation/energy to form a latent image and thermally developing the latent image in a single development step to produce a positive image in the element. The present invention is also directed to a photothermographic element that can be used in the present process in which a positive image characterized by high speed and discrimination is formed when exposed and thermally heated above 150° C.

摘要： A variable contrast photographic element containing a light sensitive silver halide emulsion layer is disclosed wherein the silver halide is sensitized with a benzimidazolooxacarbocyanine dye of the following formula (I) in an amount less than that required to impart maximum sensitivity to all of the silver halide in the emulsion. ##STR1## In formula (I), R.sup.1, R.sup.2, R.sup.6 and R.sup.7 each independently represent hydrogen, halogen, hydroxy, or substituted or unsubstituted alkyl, alkenyl, alkoxy, alkylamino, alkylthio, aryl, aryloxy, arylamino, or arylthio. R.sup.3 and R.sup.4 each independently represent substituted or unsubstituted alkyl. R.sup.5 represents a substituent containing an electron withdrawing group. X represents a counterion as needed to balance the charge of the molecule. Use of dyes of formula (I) having an R.sup.5 substituent which contains an electron withdrawing group has been found to beneficially reduce the sensitivity of variable contrast photographic elements at wavelengths longer than 570 nm, thereby enhancing safelight tolerance, while still maintaining good spectral sensitivity at wavelengths in the green region less than 560 nm.
