Novel Image Dye-Providing Materials And Photographic Products And Processes

View page
US Patent:
45981582, Jul 1, 1986
Filed:
Jan 10, 1983
Appl. No.:
6/456978
Inventors:
Stephen R. Herchen - Duxbury MA
Gary N. Widiger - Lexington MA
Assignee:
Polaroid Corporation, Patent Dept. - Cambridge MA
International Classification:
C07D31182
US Classification:
549394
Abstract:
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.
