一、原理微泡胶片是非卤化银感光材料,是重氮盐照相法。区别是在重氮印相中,见光区重氮盐分解,未见光区与偶合剂在碱性条件下偶合发色成正象。微泡胶片中,重氮化合物(也可以是叠氮或羰基化合物)在见光分解产生氮气,在载体热塑性树脂内部产生内 First, the principle Microfibrillated film is non-silver halide photographic materials, diazo salt photography method. The difference is that in the diazo printing phase, see diazonium salt light decomposition, no light and coupling agent coupling under alkaline conditions, a positive image. In a microbubble film, a diazo compound (which may also be an azide or a carbonyl compound) decomposes to produce nitrogen gas, which is internally generated within the carrier thermoplastic resin
