    摘要： Oxoindolizine and oxoindolizinium dyes are useful in photographic materials and processes as image dyes. These dyes are formed in unexposed areas of photographic materials, especially photothermographic materials, by the reaction of a photosensitive cyclopropenone with a pyridine compound. Oxoindolizine and oxoindolizinium dyes are alternatively formed by (1) reaction of a photosensitive cyclopropenone with a pyridine compound and (2) reaction of the resulting product with a color forming coupler. The photographic material is imagewise exposed and then heated to a processing temperature to form a dye image. Alternatively, the oxoindolizine and oxoindolizinium dyes are produced by imbibing at least one of the reactants into the photographic material comprising a photosensitive cyclopropenone.
