摘　　要：本文从银盐感光材料的成像机理出发,探讨了高灵敏化学型非银盐感光材料的2种研发策略:显影放大和链反应。对于一些光化学反应,无论反应产物是能够使反应原料的光活性区域发生移动,还是对某些反应具有高效的催化作用,都有望作为基础设计出具有显影放大功能的化学型非银盐感光材料。另外,本文从Lambert-Beer定律出发,推导出了发色型感光材料感光灵敏度的估算方法,可用于指导非银盐感光材料的设计及配方优化。By probing the imaging mechanism of silver halides photographic materials, two R＆D strategies toward highly sensitive photo-chemical imaging systems were discussed： signal amplification through development, and photo-initiated chain reactions. Those photochemical re- actions, in which the products could either shift the active exposure wavelength of reactants or ef- fectively catalyze some chemical reactions, pave the way for designing photo-chemical imaging materials with chemical amplification functionality. Furthermore, on the basis of Lambert-Beer＇s law, we deduced the formulas for estimating the photosensitivity of color-generating type photo- sensitive materials. This theory is valuable for the design of non-silver photographic materials and for recipe optimization.
