    摘要: A multicolor diffusion transfer photographic system wherein development of an exposed multilayer photsensitive element is effected in the presence of a ligand which is represented by the formula ##STR1## wherein R is hydrogen, alkyl or hydroxyalkyl, m is an integer of from 3 to 10 and n is 0 or an integer of from 1 to 3 with the proviso that the sum of m and n is not greater than 10.

    摘要: Trimethylamine acrylimide is prepared by condensing a mixture of 3-chloropropionyl chloride, 3-chloropropionic acid and trimethylhydrazinium p-toluenesulfonate; and then converting the thus-formed intermediate to the trimethylamine acrylimide, including the step of deprotonating with base.
