Abstract

A color photographic recording material contains a dispersion of hardened particles of a complex coacervate (packet emulsion) in at least one layer of binder, which particles are hardened with a hardener corresponding to the following formula I ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and each denotes an alkyl group with 1 to 8 carbon atoms or an aryl or aralkyl group optionally substituted with an alkyl group having 1 or 2 carbon atoms or with a halogen atom or R.sup.1 and R.sup.2 together denote the atoms required for completing a heterocyclic ring, e.g. a piperidine or morpholine ring, optionally substituted with an alkyl group having 1 or 2 carbon atoms or with a halogen atom, PA1 R.sup.3 denotes a hydrogen atom or an alkyl group having 1 or 2 carbon atoms and PA1 n represents 0 or 2.
