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.

Metallized azo thioether dyes having an azo group linking a substituted 3-hydroxypyridine nucleus to a phenyl nucleus are disclosed. The phenyl nucleus has an thioether substituent ortho to the azo group but does not have electron withdrawing substituents on the phenyl nucleus. The dyes are useful in optical recording elements.

Metallized azo ether dyes having an azo group linking a substituted 3-hydroxypyridine nucleus to a phenyl nucleus are disclosed. The phenyl nucleus has an ether substituent ortho to the azo group. The phenyl nucleus is free of strong electron withdrawing substituents. The dyes are useful in optical recording elements.

摘要:
There is disclosed a recordable optical element that includes a metallized dye. The element has a transparent substrate and on the surface of the substrate, a dye containing recording layer and a light reflecting layer. The improvement is that the dye is a metal complex of a tridentate azo dye ligand containing, on one side of the azo linkage, an aminohydroxypyridine group and on the other side, an aromatic ring including an electron withdrawing substituent. The dyes that are used in the element are very light stable.
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.
