摘要
本文对几种银漂染料的色位移和复色性能与其分子结构的关系进行了研究。结果显示,以N-苯甲酰化J-酸、G-酸、变色酸为偶合组分的染料具有较好的位移和复色性能,而以R-酸、N-酰化H-酸等为偶合组分的银漂染料性能较差。位移染料M-16、C-20的初步涂布应用表明,其样片感光度分别提高了3.8和6.3倍。
Color shifting and returning of diazo dyes used in silver dye bleach (SDB) photography were studied, focusing on the relationship between the properties and their molecular structure. The results showed that the dyes with coupling moieties of N-benzoyl J-acid, G-acid or chro-motropic acid could shift and return easily by benzoylation and debenzoylation, but those with coupling moieties of R-acid or N-acyl H-acid were difficult. Using the shifted dyes M-16 and C-20 in SDB photography, the sensitivity increased 3.8 and 6.3 times, respectively.
