摘要： A new color-forming 4-(4'-secondary or tertiary-amino)anilino-1-carboxamidonaphthalene dye precursor in a photographic material and process enables formation of a dye image by means of cross-oxidation without the need for a coupling reaction. The color-forming 4-(4'-secondary or tertiary-amino)anilino-1-carboxamidonaphthalene dye precursor is useful in a photographic silver halide material for producing (i) a dye image, or (ii) a dye image and silver image. The exposed photographic material is processed to produce (a) a positive dye image, (b) a negative dye and negative silver image, (c) a negative dye image or (d) a positive dye image and a positive silver image. New naphthoquinoneimide dyes are also described.

摘要： A coupler containing in the coupling position a carbamoyloxy group ##STR1## upon oxidative coupling, releases a carbamic acid fragment that, in turn, is capable of thermally releasing ammonia or an amine. Such a carbamoyloxy substituted coupler and carbamic acid fragment are useful in imaging such as in photothermography and thermography. Ammonia or an amine released from the carbamic acid fragment enables imaging in imaging materials that are responsive to ammonia or an amine. The carbamoyloxy substituted coupler also generally is a dye-forming coupler that reacts with the oxidized form of a color developing agent to form a dye. An image is produced in an exposed photothermographic material comprising the carbamoyloxy substituted coupler by thermal development. An image is produced in a thermographic material comprising the carbamoyloxy substituted coupler and a color developing agent by imagewise heating the thermographic material.
