There are described novel compounds which are represented by the formula
wherein R is -CH2-A- or -CH2- = A; A is sulfur or selenium; X represents the nonmetallic atoms necessary to form a nucleus which completes a five or six membered heterocyclic moiety; R, is H or lower alkyl; R2 is H or a hydrolyzable group; and R3 is H, alkyl or a hydrolyzable group. The compounds are useful in photographic applications and provide controlled release of a photographically useful material during processing of photographic elements with an aqueous alkaline processing composition.
所述新型化合物由以下式子表示
其中 R 是-CH2-A-或-CH2- = A;A 是硫或硒;X 代表形成核所需的非金属原子,该核完成一个五或六成员杂环分子;R 是 H 或低级烷基;R2 是 H 或可水解基团;R3 是 H、烷基或可水解基团。这些化合物在摄影应用中非常有用,可在使用水性碱性冲洗组合物冲洗照片元件时,控制释放对摄影有用的材料。
