Abstract
There are disclosed dyes, compositions, imaging elements, and methods of forming images, wherein cyclopropenones are reacted with di- or tri-halogenated compounds in the presence of pyridine to form said dyes. In areas exposed to activating radiation, the cyclopropenone decomposes and prevents the dye reaction from occurring.
