    • 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.
    • 通过显影发展获得的照相彩色图像的储存稳定性可以通过能够与伯胺反应的式I化合物,特别是彩色显影剂化合物(伯胺试剂)来改善。 可以将该配方化合物加入到彩色照相记录材料中,或加入到显影下游的处理浴中。 此外,式I化合物适合作为用过的照相处理槽或其溢流剂的添加剂,以便在处理槽或溢出处理或再生以供进一步使用之前将其中的显色剂化合物的含量减少。 (I)式Ⅰ中,A表示-OR2,-SR2或-NR2R3; R1表示H中的H,烷基,芳基,酰基,磺酰基或残基,或与A或与Z1一起形成环的残基; R2表示H,烷基,芳基,酰基,磺酰基; R3表示残基,如R2或任选残基,其与R2和N原子一起形成杂环,Z1和Z2相互独立地表示:H,卤素,氰基,烷基,芳基,酰基,杂环基,烷氧基羰基 ,芳氧基羰基,磺酰基,亚氨基,亚氨基,氨磺酰基,碳酰氨基或磺酰氨基; 其中Z1和Z2与它们所连接的C原子一起可以形成碳环或杂环系。
