摘要： Procédé de formation d'une image photographique de coloration azo ou azaméthine dans un élément photographique exposé d'halogénure d'argent, ce procédé consistant à a) développer le matériau exposé pour former un motif d'un agent révélateur de couleur oxydé reproduisant l'image, b) faire réagir l'agent révélateur de couleur oxydé avec un copulant de couleur pour produire une image de couleur, cette étape se caractérisant en ce qu'au moins l'agent révélateur de couleur ou le copulant de couleur possède un site de chélation de métal tel que l'image de couleur peut former une matière colorante bidentée, tridentée ou multidentée, c) mettre en contact l'image de couleur avec des ions métalliques polyvalents pour former une image de couleur métallisée. Des agents révélateurs de couleur spécifiques comprennent des hydrazides substitués hétérocycliques et des copulants spécifiques comprennent des benzyso-oxazolones et des 2H-pyrazolo- AD3,4-b BDpyridines ajoutés avec des composés plus conventionnels.

摘要： A method of forming a photographic azo or azamethine dye image in an exposed photographic silver halide element, the method comprising the steps of a) developing the imagewise exposed material to form an imagewise pattern of oxidised colour developing agent, b) reacting the oxidised colour developing agent with a colour coupler to produce an image dye, characterized in that at least one of the colour developing agent and the colour coupler possesses a metal chelating site such that the image dye is capable of forming a bi-, tri- or higher-dentate metallised dye, and c) contacting the image dye with polyvalent metal ions to form a metallised dye image. Specified colour developing agents include heterocyclic substituted hydrazides and specified couplers include benziso-oxazolones and 2H-pyrazolo-[3,4-b]pyridines in addition to more conventional compounds.

摘要： There is provided a photographic element comprising at least one silver halide emulsion layer having associated therewith a novel phenolic cyan dye-forming coupler of formula (I), wherein X is hydrogen or a group that can be split off by the reaction of the coupler with an oxidised colour developing agent, and one of Y and Z is the group represented by formula (II), wherein each R is independently an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; R1 is hydrogen or an unsubstituted or substituted alkyl or aryl group, R2 is an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted R3 is hydrogen of an unsubstituted or substituted alkyl or aryl group, n is 1 or 2, and the other of Y and Z is an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted. The couplers for use in the element of the invention yield cyan images of good hue, with good stability to heat, humidity and light, whilst retaining the other properties desirable for good photographic performance.

摘要： A multiple layer photosensitive element having at least three differently sensitised photosensitive layers on one side of a support, such as a , transparent flexible support, is imagewise exposed according to a desired circuit pattern and developed to form two layers of conductive track patterns from each photosensitive layer, which may then be connected together by forming vias by drilling or in situ generation. The resulting multiple layer conductive element has application in the field of printed circuit board manufacture or as the backplane electronic element of a flexible display device.
