摘要: 研究了带有不同取代基的显影促进基团对DAR成色剂照相性能的影响.通过比较3个母体及吸附基团相同而显影促进基团不同的DAR成色剂的照相性能,发现不同酰基取代的显影促进基团对DAR成色剂的照相性能有较大的影响,其中带三氟乙酰基取代的显影促进基团的DAR成色剂的照相性能最佳.

Abstract: The effect of DAR couplers with different development accelerating group on photographic properties was researched. Comparing the photographic properties of DAR coupler which contained the same coupler moiety and adsorption group, while contained different development accelerating group. It was found that with different substitute group, the development-accelerating group affected the photographic properties of DAR coupler significantly. The photographic properties of DAR coupler, which contained trifluoroacetyl substitute development-accelerating group, was the best. And at the same time had good anti-aging properties, whereas did not change the absorption spectrum of the main coupler development.

Key words: DAR coupler, β-acylphenylhydrazine development accelerator, cyan coupler, photographic properties
