    摘要: Disclosed is a class of dyes that can be rendered colorless by the application of heat in a silverless imaging system and which have utility in information recording and display, color hard copy and photographic systems. Certain dye ylides, for example, xanthane dye ylides are disclosed which when incorporated in a thin film can be imagewise heated to develop an image by reason of the ylide dye disassociating in the areas where heated and thereby being rendered colorless.

    摘要: Diffusion transfer photographic color processes and products are described utilizing novel image dye-providing materials which provide image dyes having the chromophoric system represented by the formula ##STR1## wherein X is ##STR2## or --SO.sub.2 --R.sub.1 ; Z is H, alkyl or aryl; R is H, alkyl or aryl; DYE is any dye moiety; R.sub.1 is H, alkyl, aryl, --NH.sub.2, --NHR.sub.2, --N(R.sub.2).sub.2 or --OR.sub.2 ; R.sub.2 is H, alkyl or aryl; and m is 1 or 2. The image dye providing material includes a diffusion control moiety such as a hydroquinonyl group or a precursor thereof and may be diffusible or nondiffusible as a function of the diffusion control moiety.
