A novel photographic development inhibitor releasing coupler (A) comprises a coupler moiety bonded to at least one timing group that enables timing of release of a releasable development inhibitor moiety wherein the releasable development inhibitor moiety contains a -CH2-Q group that is bonded directly to the inhibitor moiety and that is a group enabling, upon exposure and processing of a photographic element containing the coupler, reduced interlayer interimage effect without reduced image acutance. The coupler (A) is useful in a color photographic silver halide element and process.
一种新型感光显影
抑制剂释放耦合剂(A)包含一个与至少一个定时基团结合的耦合剂分子,该定时基团能够定时释放可释放的显影
抑制剂分子,其中可释放的显影
抑制剂分子包含一个直接与
抑制剂分子结合的-
CH2-Q基团,该基团能够在对包含该耦合剂的感光元件进行曝光和冲洗时,减少层间间歇效应,而不会降低图像的清晰度。耦合剂(A)适用于彩色卤化
