Abstract
A mordant layer for a color diffusion transfer photographic element containing a cationic polymer latex obtained by emulsion-polymerizing a monomer represented by formula (I) ##STR1## wherein R.sub.1 and R.sub.2 each represents hydrogen or an alkyl group having from 1 to 6 carbon atoms; R.sub.3, R.sub.4, and R.sub.5 each can represent an alkyl group having from 1 to 20 carbon atoms, or an aralkyl group having from 7 to 10 carbon atoms, or any two or R.sub.3, R.sub.4, and R.sub.5 together can form a ring; and X.sup..crclbar. represents an anion; as a shell component for a core component of dispersed particles of a polymer latex obtained by emulsion-polymerizing a water-insoluble monomer or monomers other than the monomer of formula (I).
