ABSTRACT:
In a photographic element for the color diffusion transfer process having a neutralizing system comprising a neutralizing layer and a timing layer, the improvement which comprises said timing layer containing a mixture of acetyl cellulose and a polymer represented by the general formula (I): ##STR1## wherein A represents a repeating unit represented by the general formula (II): ##STR2## wherein R.sub.2 represents a hydrogen atom, a halogen atom, or a methyl group; R.sub.3 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, ##STR3## R.sub.4 represents an alkyl group or an aralkyl group; R.sub.5 and R.sub.6, which may be the same or different, each represents an alkyl group, an aryl group, or an aralkyl group; and a represents 0 or 1; R.sub.1 represents an alkyl group, an aryl group or an aralkyl group; B represents a repeating unit derived from an ethylene-type monomer different than A excluding the monomer component having the formula ##STR4## x is about 20 to 90 mol %; y is about 10 to 80 mol %; and z is about 0 to 30 mol %.
