Action of DIAR coupler linked by a new moiety to photographic material

本文阐述了功能性成色剂,特别是DLAR成色剂分子中功能基与成色剂母体之间连接基的种类,不同连接基对功能性成色剂稳定性和影像性能的影响;列举了含有典型连接基的功能性成色剂的制备方法。

Photographic compound capable of releasing a photographiclly useful group(PUG).espectaily as DIAR coupler s reviewed. A summary about a link moiety(LINK) which exists between the coupler moiety and the PUG, the type of LINK group, the ettects of various LINK group, to image sharpnes, and fog increase on the processeo material are disoussed. The synthese, of particular compounds, especially DIAR couplers are illu-tracted,
