High edge effects and interimage effects are provided in a color-photographic material by the use of new DIR-compounds. These are of the formula ##STR1## wherein X represents together with the sulfur atom a development inhibiting group; Y represents --O--, ##STR2## methylene group which may be alkyl substituted or a methine group; Z represents a methylene or ethylene group which may be alkyl substituted, a methine group, a vinylene group, an o-phenylene group, a carbonyl group, an oxycarbonyl group or a carbonamide group; R.sup.1 and R.sup.2 represent aliphatic, araliphatic or aromatic groups, acyl, acyloxy, alkoxy, aryloxy, amino, halogen, cyano, thioether groups or arylsulfoxyl or alkylsulfoxyl or both R.sup.1 and R.sup.2 together complete an at least mono-unsaturated or aromatic ring.
新的DIR化合物的使用在彩色摄影材料中提供了高边缘效应和图像间效应。这些化合物的化学式为##STR1##其中X与硫原子一起表示发展抑制基团;Y表示--O--,##STR2##亚甲基基团,可以是烷基取代的或甲基取代的亚甲基基团;Z表示可以是烷基取代的亚甲基或乙烯基,甲基基团,乙烯基,o-苯基,羰基,氧羰基或碳酰胺基;R1和R2表示脂肪族,芳基脂肪族或芳香族基团,酰基,酰氧基,烷氧基,芳基氧基,氨基,卤素,氰基,硫醚基团或芳基亚砜基团或烷基亚砜基团或R1和R2共同完成至少一个单不饱和或芳香环。
