    摘要: The storage stability of photographic color images obtained by chromogenic development may be improved by compounds of the formula I, which are capable of reacting with primary amines, in particular color developer compounds (reagent for primary amines). The compounds of the formula may be added to the color photographic recording material or to a treatment bath downstream from color development. Compounds of the formula I are moreover suitable as an additive to a spent photographic processing bath or its overflow in order to reduce therein the content of color developer compounds before the processing bath or the overflow is disposed of or regenerated for further use. ##STR1## In formula I: A means --OR.sup.2, --SR.sup.2 or --NR.sup.2 R.sup.3 ; R.sup.1 means H, alkyl, aryl, acyl, sulphonyl or a residue as in A or a residue which, together with A or together with Z.sup.1, completes a ring;R.sup.2 means H, alkyl, aryl, acyl, sulphonyl; R.sup.3 means a residue as in R.sup.2 or optionally a residue which, together with R.sup.2 and the N atom, forms a heterocyclic ring, Z.sup.1 and Z.sup.2 mutually independently mean: H, halogen, cyano, alkyl, aryl, acyl, a heterocyclic group, alkoxycarbonyl, aroxycarbonyl, sulphonyl, imino, imido, sulphamoyl, carbonamido or sulphonamido; wherein Z.sup.1 and Z.sup.2, together with the C atom to which they are attached, may form a carbocyclic or heterocyclic ring system.
